Approaches and Key Concepts in International Relations — UPSC PSIR Optional Notes

1. Idealism: Origins and Core Ideas

Birth of the discipline: International Relations became an academic subject after the First World War; the first chair, the Woodrow Wilson Chair at Aberystwyth (1919), was set up to study how to prevent war, and Alfred Zimmern was its first holder.

Philosophical roots: Immanuel Kant, Perpetual Peace (1795), proposed three definitive articles: every state should have a republican constitution, international right should rest on a federation of free states, and cosmopolitan right should be limited to universal hospitality. Grotius (international law), Bentham and Richard Cobden (free trade) also shaped liberal thinking.

Wilson's Fourteen Points (8 January 1918): open covenants openly arrived at, freedom of the seas, removal of trade barriers, reduction of armaments, adjustment of colonial claims, self-determination for many peoples and a general association of nations.

Interdependence argument: Norman Angell, The Great Illusion (1910), argued that in an interdependent economy war cannot bring economic gain even to the victor.

Core assumptions: human nature is good or improvable; there is a natural harmony of interests among peoples; war results from bad institutions, secret diplomacy and autocracy; public opinion, international law, disarmament and collective security can secure peace.

Institutions: the League of Nations (1920), the Permanent Court of International Justice and the Kellogg-Briand Pact (1928), in which states renounced war as an instrument of national policy.

Failure: the US Senate refused to join the League, and the League failed to stop Japan in Manchuria (1931) and Italy in Abyssinia (1935 to 1936); appeasement at Munich (1938) and the Second World War discredited interwar idealism.

2. Carr's Critique and the First Great Debate

Carr: E.H. Carr, The Twenty Years' Crisis, 1919-1939 (1939), called the idealists 'utopians'. He argued that the 'harmony of interests' disguised the interests of satisfied, dominant powers such as Britain, and that morality in international politics reflects power.

Carr's balance: Carr also criticised pure realism as sterile, since it offers no goal for action; he argued that sound thought must combine utopia and reality.

The 'first great debate': the contest between idealism and realism is called the first great debate of IR. Later historians of the discipline (such as Peter Wilson and Lucian Ashworth) argued that it was partly a myth constructed afterwards, since interwar liberals were less naive than portrayed.

Legacy: idealism returned as liberal internationalism in the UN Charter, human rights law, European integration and democratic peace theory.

3. Classical Realism

Roots: Thucydides' account of the Melian dialogue in the History of the Peloponnesian War, where the Athenians tell the Melians that the strong do what they can and the weak suffer what they must; Machiavelli's The Prince (written 1513); and Thomas Hobbes's Leviathan (1651), where life without a common power is a war of all against all.

Niebuhr: Reinhold Niebuhr, Moral Man and Immoral Society (1932), argued that groups and nations are more selfish than individuals, so politics among nations cannot follow private morality.

Morgenthau: Hans Morgenthau, Politics Among Nations (1948), gave realism its classic form through six principles of political realism.

Principles one to three: politics is governed by objective laws rooted in human nature; the main signpost of international politics is the concept of interest defined in terms of power; the idea of interest is universal, but its content changes with time and circumstance.

Principles four to six: universal moral principles must be filtered through concrete circumstances, so prudence is the supreme political virtue; a nation must not identify its own moral aspirations with the moral laws of the universe; and the political sphere is autonomous from economics, law and ethics.

Shared realist assumptions: states are the main actors; the system is anarchic (no world government); survival is the first goal; states rely on self-help; power is the currency of politics; and progress is limited.

Containment: George Kennan's 'X' article, 'The Sources of Soviet Conduct' (Foreign Affairs, 1947), set out the realist strategy of containing the Soviet Union.

Other classical realists: Raymond Aron, Peace and War (1962), and the statecraft of Henry Kissinger, including the US opening to China (1971 to 1972), are standard examples.

Balance as prudence: classical realists saw the balance of power and skilled diplomacy, not law, as the best means of limiting war.

4. Neorealism and Its Rivals

Waltz's three images: Kenneth Waltz, Man, the State and War (1959), located the causes of war in human nature (first image), the internal nature of states (second image) and the anarchic international system (third image), and gave priority to the third.

Structural realism: Waltz, Theory of International Politics (1979), defined structure by its ordering principle (anarchy), the functions of units (alike, since all must survive) and the distribution of capabilities. States balance against power, and he judged a bipolar system more stable than a multipolar one.

Defensive and offensive realism: defensive realists (Waltz, Stephen Walt, Robert Jervis) argue that states seek enough power to be secure. John Mearsheimer, The Tragedy of Great Power Politics (2001), argued that states maximise power and seek regional hegemony.

Neoclassical realism: Gideon Rose named this school in a 1998 World Politics article; it holds that systemic pressures are filtered through domestic factors such as leaders' perceptions and state capacity.

Neoliberal institutionalism: Robert Keohane and Joseph Nye, Power and Interdependence (1977), described complex interdependence; Keohane, After Hegemony (1984), argued that institutions make cooperation possible under anarchy. Joseph Grieco (1988) replied that states care about relative, not only absolute, gains (the 'neo-neo' debate).

Democratic peace: Michael Doyle, 'Kant, Liberal Legacies, and Foreign Affairs' (1983), revived Kant's argument by showing that liberal democracies have rarely, if ever, fought one another.

5. Critiques of Realism

Explanatory failure: realism did not foresee the peaceful end of the Cold War, which was driven largely by ideas and domestic change in the Soviet Union.

Constructivism: Alexander Wendt, 'Anarchy is What States Make of It' (International Organization, 1992), argued that anarchy has no fixed logic; its meaning depends on shared ideas and identities.

Feminism: J. Ann Tickner (Millennium, 1988) reformulated Morgenthau's six principles from a feminist perspective, arguing that his 'objective' laws reflect masculine traits; Cynthia Enloe, Bananas, Beaches and Bases (1989), showed women's hidden roles in international politics.

Liberal critique: realism ignores interdependence, institutions, non-state actors and the decline of war among developed democracies.

Conceptual and normative critique: power and national interest are elastic and hard to measure; realist policy can become a self-fulfilling prophecy that intensifies the security dilemma.

Postcolonial critique: realism is centred on European great powers and overlooks the agency and experience of the Global South.

6. Indian Context

Kautilya's realism: the Arthashastra set out the saptanga theory of the state, the mandala theory (a neighbouring state is a natural enemy and the state beyond it a natural friend), the six-fold policy (sandhi, vigraha, asana, yana, samshraya, dvaidhibhava) and the four upayas (sama, dana, bheda, danda), centuries before Machiavelli.

Nehru's idealism: Panchsheel (the five principles in the India-China agreement of April 1954), non-alignment, faith in the UN and calls for disarmament are often read as idealist.

Nehru's realism: Nehru also presented non-alignment as a way of protecting India's freedom of action and interests, and used force in Hyderabad (1948) and Goa (1961).

Turn after 1962: the war with China is widely seen as a lesson in the limits of idealism, leading to military modernisation.

Realist moves: the Indo-Soviet Treaty of Peace, Friendship and Cooperation (August 1971) before the Bangladesh war, the Pokhran-II tests (May 1998) and the India-US civil nuclear agreement (2005 to 2008).

Today: strategic autonomy and multi-alignment; S. Jaishankar, The India Way (2020), argued for a pragmatic, interest-based policy that engages all major powers.

Continuing idealism: the G20 presidency theme 'One Earth, One Family, One Future' (2023), drawn from Vasudhaiva Kutumbakam, and the Gandhian legacy of non-violence keep a normative strand alive.

7. Using It in the Exam

10-mark answer: state the core assumption of each approach, name one key thinker and work for each, and add one Indian example.

20-mark answer: context of 1919; idealist assumptions and institutions; Carr's critique; Morgenthau's principles; Waltz's structural turn; critiques; India's blend of the two; conclude that most foreign policies combine power and principle.

Keywords: harmony of interests, collective security, anarchy, self-help, interest defined as power, prudence, three images, offensive and defensive realism.

Quotations: Morgenthau's 'interest defined in terms of power' (Politics Among Nations); Lord Palmerston in the House of Commons (1848) that Britain has no eternal allies and no perpetual enemies, only eternal and perpetual interests (paraphrase).

Tip: do not present realism as one theory; distinguish classical, structural, offensive, defensive and neoclassical realism.

1. Marxist Approach: Classical Foundations

Marx and Engels: they wrote no theory of international relations, but the Communist Manifesto (1848) described how the bourgeoisie creates a world market and declared that 'the working men have no country'.

Core logic: international relations reflect relations of production; states serve dominant classes; the real conflicts are between classes across borders, and war and expansion arise from the needs of capital.

Hobson: J.A. Hobson, a liberal, argued in Imperialism: A Study (1902) that under-consumption at home drove capitalists to seek overseas markets and investment, causing imperialism.

Hilferding: Rudolf Hilferding, Finance Capital (1910), described the fusion of bank capital and industrial capital under monopoly capitalism.

Lenin: V.I. Lenin, Imperialism, the Highest Stage of Capitalism (written 1916, published 1917), listed five features: monopolies, finance capital and a financial oligarchy, export of capital rather than goods, international monopolist combines dividing the world, and the completed territorial division of the world among the great powers. He called the First World War an imperialist war for redivision.

Luxemburg: Rosa Luxemburg, The Accumulation of Capital (1913), argued that capitalism needs non-capitalist areas to absorb its surplus, which drives colonial expansion.

2. Neo-Marxist Variants

Dependency theory: Prebisch, Frank and Amin argued that the periphery is kept underdeveloped by its links with the capitalist core (see Chapter 11).

World-systems theory: Immanuel Wallerstein divided the capitalist world-economy into core, semi-periphery and periphery, and traced successive hegemonies of the Dutch, the British and the Americans.

Gramscian IR: Robert Cox, 'Social Forces, States and World Orders: Beyond International Relations Theory' (Millennium, 1981), wrote that 'theory is always for someone and for some purpose'. He contrasted problem-solving theory, which takes the existing order as given, with critical theory, which asks how that order arose and can change, and saw hegemony as a fit between ideas, material capabilities and institutions.

Hegemony as consent: following Antonio Gramsci, neo-Gramscians see global hegemony as leadership based on consent backed by coercion; Stephen Gill described 'disciplinary neoliberalism' that locks market rules into international agreements.

Critical theory: Andrew Linklater and others in the Frankfurt School tradition seek the emancipation of humanity from unjust structures, including the exclusions of the sovereign state.

New imperialism: David Harvey, The New Imperialism (2003), described 'accumulation by dispossession' through privatisation, financialisation and the seizure of common resources.

3. Evaluation of the Marxist Approach

Strengths: it reveals the economic roots of conflict, explains North-South inequality and exposes the interests behind claims of a neutral world order.

Weaknesses: economic reductionism; in 1914 nationalism defeated working-class internationalism as most socialist parties backed their national governments; socialist states fought each other (Sino-Soviet border clashes 1969, China and Vietnam 1979); and the collapse of the USSR and the rise of East Asia undercut key predictions.

Realist critique: Waltz classified theories of imperialism as reductionist, explaining international outcomes from the internal nature of states instead of from the system.

Continuing relevance: global inequality, financial crises and debates on the power of capital keep Marxist and critical approaches alive.

4. Functionalism and Neo-functionalism

Mitrany: David Mitrany, A Working Peace System (1943), argued that peace would come not from grand political federations but from cooperation in specific technical tasks such as transport, health and communications, run by functional agencies.

Key ideas of functionalism: 'form follows function' (the task decides the shape of the institution); 'ramification' (success in one area spreads cooperation to others); and gradual transfer of people's loyalties from states to functional bodies, reducing the scope for war.

Examples: early functional bodies such as the International Telegraph Union (1865) and the Universal Postal Union (1874), and UN specialised agencies such as the ILO, WHO and FAO.

Neo-functionalism: Ernst Haas, The Uniting of Europe (1958), studied the European Coal and Steel Community and introduced 'spillover'. Functional spillover means integration in one sector creates pressure to integrate linked sectors; political spillover means elites and interest groups shift their expectations and loyalties to a new supranational centre.

European practice: the Schuman Declaration (9 May 1950), drafted with Jean Monnet, led to the ECSC (Treaty of Paris, 1951), then the EEC (Treaty of Rome, 1957), the Single European Act (1986) and the Maastricht Treaty (1992) that created the European Union.

Development and doubt: Leon Lindberg and Philippe Schmitter refined the theory, but Haas himself called regional integration theory 'obsolescent' in 1975.

Intergovernmentalist critique: de Gaulle's 'empty chair' crisis (1965) and the Luxembourg Compromise (1966) showed states defending sovereignty. Stanley Hoffmann, 'Obstinate or Obsolete?' (1966), argued that integration works in 'low politics' but stalls in 'high politics'; Andrew Moravcsik, The Choice for Europe (1998), explained integration through bargaining among national governments.

Spillback: the eurozone crisis and Brexit (the UK left the EU on 31 January 2020) show that integration can reverse; Liesbet Hooghe and Gary Marks's 'postfunctionalism' (2009) stressed that identity politics now constrains integration.

Beyond Europe: ASEAN (1967), the African Union and Mercosur show functional cooperation with much weaker spillover and stronger respect for sovereignty.

5. Systems Approach

Background: drawing on general systems theory and David Easton, scholars treated international politics as a system of interacting units whose patterns could be studied as a whole.

Kaplan: Morton Kaplan, System and Process in International Politics (1957), built six models: the balance of power system, the loose bipolar system, the tight bipolar system, the universal system, the hierarchical system and the unit veto system. Each has rules of behaviour; in the balance of power system, for example, states increase capabilities but prefer negotiation to war and do not eliminate an essential actor.

Rosecrance: Richard Rosecrance, Action and Reaction in World Politics (1963), compared nine historical European systems from 1740 and linked stability to elite security, control and available resources.

Other contributors: Charles McClelland applied event-interaction analysis, and Stanley Hoffmann proposed a historical sociology of international systems.

Polarity debate: Karl Deutsch and J. David Singer (1964) argued that multipolar systems are more stable, while Waltz, 'The Stability of a Bipolar World' (Daedalus, 1964), argued that bipolarity is more stable.

Waltz's structural theory: the most influential systems theory, it distinguished systemic theories from reductionist ones and explained recurring patterns, such as balancing, by the structure of the system.

Critiques: the models are abstract and hard to test, tend to be static, neglect domestic politics, ideas and non-state actors, and Kaplan's models were largely hypothetical rather than drawn from history.

6. Indian Context

Marxist and Third World readings: India saw colonialism and neo-colonialism as structural problems; it helped launch UNCTAD (first session 1964) and backed the G-77 call for a New International Economic Order adopted by the UN General Assembly in 1974.

Dependency and planning: fears of dependence shaped India's import-substitution and self-reliance strategy during the planning era.

Functionalism in South Asia: SAARC (1985) was designed around functional cooperation (agriculture, health, trade), and its Charter excludes bilateral and contentious issues. India-Pakistan hostility has stalled it; the last summit was held in Kathmandu in 2014, and the 2016 Islamabad summit was called off after the Uri attack.

Sub-regional alternatives: India has turned to BIMSTEC (1997) and the BBIN Motor Vehicles Agreement (2015) as more workable functional groupings.

Indus Waters Treaty: the 1960 treaty with Pakistan was long cited as functional cooperation that survived wars; after the Pahalgam terror attack, India placed it in abeyance in April 2025.

Systems view of non-alignment: non-alignment was India's response to a bipolar system and fits Kaplan's loose bipolar model, in which non-aligned actors moderate bloc rivalry; in today's emerging multipolarity India pursues multi-alignment.

7. Using It in the Exam

10-mark answer: state the core claim of the approach, name the key thinker and work, give one example and one criticism.

20-mark answer: explain the origin and assumptions; present the classical and later versions (Lenin to Cox; Mitrany to Haas; Kaplan to Waltz); evaluate with evidence (1914, the EU, the Cold War); apply to India or South Asia; conclude on present relevance.

Keywords: imperialism, finance capital, core and periphery, hegemony, ramification, spillover, supranationalism, unit veto, polarity.

Quotation: Robert Cox, 'Theory is always for someone and for some purpose' (1981).

Tip: keep functionalism (technical, global, apolitical) distinct from neo-functionalism (regional, political, supranational); examiners often test this difference.

1. National Interest: Meaning and Classification

Meaning: national interest refers to the goals a state seeks in its relations with other states; it is the main criterion for judging foreign policy. It replaced older ideas such as raison d'état (associated with Cardinal Richelieu) and the will of the prince.

Beard: Charles Beard, The Idea of National Interest (1934), traced how the concept entered American foreign policy as the basis of state action.

Morgenthau: treated national interest defined as power as the guide to policy, and argued that the irreducible minimum is survival, meaning the protection of a nation's physical, political and cultural identity against encroachment by others.

Frankel: Joseph Frankel, National Interest (1970), distinguished aspirational interests (long-term ideals), operational interests (actual policy goals) and explanatory or polemical uses (justifying policy in debate).

Robinson's classification: Thomas W. Robinson divided interests into primary (survival, security, identity), secondary, permanent, variable, general and specific, and noted that interests may be identical, complementary or conflicting with those of other states.

Objective and subjective views: realists see national interest as objective, set by geography and power; decision-making theorists such as Richard Snyder, H.W. Bruck and Burton Sapin (1954) see it as whatever decision-makers define it to be.

2. Debates on National Interest

Elasticity: critics argue that the concept is so broad it can justify almost any policy, and that it hides whose interest (a class, an elite, a party) is actually served.

Marxist view: 'national' interest masks the interest of the ruling class.

Constructivist view: Martha Finnemore, National Interests in International Society (1996), and Jutta Weldes, 'Constructing National Interests' (1996), argued that interests are not given but produced by identities and international norms.

Liberal view: Andrew Moravcsik, 'Taking Preferences Seriously' (1997), argued that state preferences come from domestic groups and institutions.

Means of promoting national interest: diplomacy, propaganda and public diplomacy, economic tools (aid, trade, sanctions), alliances, and coercion or war.

3. Security: From Traditional to Comprehensive

Traditional view: security means protecting the state's territory, sovereignty and political independence against military threats; it is state-centric and realist.

Wolfers: Arnold Wolfers, 'National Security as an Ambiguous Symbol' (1952), wrote that security in an objective sense measures the absence of threats to acquired values, and in a subjective sense the absence of fear that such values will be attacked.

Security dilemma: John Herz coined the term (1950): measures a state takes for its own security make others less secure, producing arms races even when no one intends aggression. Herbert Butterfield described the same tragedy, and Robert Jervis, 'Cooperation under the Security Dilemma' (1978), showed it is sharper when offence has the advantage and when offensive and defensive weapons cannot be told apart.

Buzan's sectors: Barry Buzan, People, States and Fear (1983), widened security to five sectors: military, political, economic, societal and environmental.

Securitisation: the Copenhagen School (Ole Wæver, 1995; Buzan, Wæver and Jaap de Wilde, Security: A New Framework for Analysis, 1998) treats security as a speech act: when an audience accepts that an issue is an existential threat, it moves out of normal politics and justifies emergency measures. Desecuritisation returns it to normal politics.

Regional security complexes: Buzan and Wæver, Regions and Powers (2003), argued that security interdependence is regional; South Asia forms a complex centred on India-Pakistan rivalry, increasingly shaped by China.

Human security: the UNDP Human Development Report (1994), shaped by Mahbub ul Haq, shifted focus from states to people: freedom from fear and freedom from want, across seven dimensions (economic, food, health, environmental, personal, community and political security).

Responsibility to protect: the International Commission on Intervention and State Sovereignty (2001) and the 2005 World Summit endorsed the idea that states must protect their populations from genocide, war crimes, ethnic cleansing and crimes against humanity, with the international community acting if they fail.

Non-traditional and critical security: terrorism, cyber attacks, pandemics, climate change, energy and migration are now security issues; Ken Booth (1991) argued for security as emancipation of people rather than protection of states.

4. Power: Meaning and Forms

Morgenthau: defined political power as man's control over the minds and actions of other men.

Dahl: Robert Dahl, 'The Concept of Power' (1957): 'A has power over B to the extent that he can get B to do something that B would not otherwise do'.

Faces of power: beyond open decision-making, Peter Bachrach and Morton Baratz (1962) added agenda-setting, and Steven Lukes, Power: A Radical View (1974), added a third dimension, shaping others' preferences.

Resources versus outcomes: power as capabilities does not always convert into outcomes, as the 'paradox of unrealised power' of the USA in Vietnam showed.

Elements of national power (Morgenthau): geography, natural resources, industrial capacity, military preparedness, population, national character, national morale, quality of diplomacy and quality of government.

Hard power: the use of military force and economic coercion or inducement (sticks and carrots).

Soft power: Joseph Nye, Bound to Lead (1990) and Soft Power (2004), defined it as the ability to get what you want through attraction rather than coercion or payment, drawing on culture, political values and legitimate foreign policies.

Smart and sharp power: smart power combines hard and soft tools (Nye; Suzanne Nossel, 2004). 'Sharp power', a term used by the National Endowment for Democracy (2017), describes authoritarian efforts to manipulate other societies' information spaces.

Structural power: Susan Strange, States and Markets (1988), defined it as the power to shape the frameworks within which others act, through four structures: security, production, finance and knowledge.

Measuring power: indices such as the Correlates of War composite index and the Chinese idea of 'comprehensive national power' try to combine military, economic and social factors, but intangibles such as morale and leadership resist measurement.

5. How the Three Concepts Connect

Ends and means: national interest defines goals, security is the most basic of those goals, and power is the means; realists tend to fuse the three, while liberals and constructivists separate them.

Dynamic link: changes in the distribution of power alter perceived interests and threats, which is why rising powers and power transitions create security dilemmas.

6. Indian Context

India's core interests: territorial integrity, security against Pakistan-backed terrorism and Chinese pressure, rapid development, strategic autonomy, energy security, welfare of the diaspora and a greater role in global institutions, including permanent membership of the UN Security Council.

Kautilya on power: the Arthashastra describes three kinds of power: mantra shakti (power of counsel and wisdom), prabhava shakti (power of treasury and army) and utsaha shakti (power of energy and valour).

Security institutions: the National Security Council (1998), reforms after the Kargil Review Committee (1999, chaired by K. Subrahmanyam), and the post of Chief of Defence Staff (created January 2020).

Non-traditional security: Left-wing extremism, cyber security (CERT-In), maritime security through SAGAR (2015), later expanded as MAHASAGAR (2025), and climate and energy security.

Counter-terror posture: the surgical strikes (September 2016), the Balakot air strike (February 2019) and Operation Sindoor (May 2025) after the Pahalgam attack signal a readiness to respond militarily to cross-border terrorism.

Soft power: yoga (the UN General Assembly declared 21 June the International Day of Yoga in December 2014), cinema, the diaspora (Pravasi Bharatiya Divas since 2003), the ICCR (1950) and vaccine supplies under Vaccine Maitri (2021).

Human security and R2P: India supports development-centred human security but is wary of the use of R2P for regime change; it abstained on UN Security Council Resolution 1973 on Libya (2011).

7. Using It in the Exam

10-mark answer: define the concept with a thinker, give one classification or contrast (traditional versus non-traditional, hard versus soft), and add one Indian example.

20-mark answer: define; explain realist, liberal, constructivist and Marxist views; trace the widening of security or the forms of power; evaluate; apply to India; conclude with the relevance of comprehensive or smart power.

Keywords: national interest defined as power, security dilemma, securitisation, human security, soft power, structural power, comprehensive national power, strategic autonomy.

Quotations: Dahl's definition of power (1957); Nye's idea of power through attraction (paraphrase).

Tip: avoid treating power as only military; examiners reward answers that cover economic, technological and soft dimensions.

1. Balance of Power: Meaning

Core idea: balance of power refers both to a distribution of power in which no single state can dominate the others and to the policy of preventing any state from achieving such dominance.

Many meanings: Ernst Haas, 'The Balance of Power: Prescription, Concept, or Propaganda?' (World Politics, 1953), found eight distinct meanings of the term, showing how loosely it is used.

Claude's four usages: Inis Claude, Power and International Relations (1962), separated balance of power as a situation (equilibrium), a policy, a system and a symbol.

Morgenthau: saw the balance of power as the natural and necessary outcome of the struggle for power among sovereign states, and as a stabilising factor in a society of states.

Assumptions: several states of roughly comparable power, rational leaders, flexible alliances not bound by ideology, willingness to use force when needed, and ideally a 'balancer' that throws its weight against whichever side becomes too strong.

2. History of the Balance of Power

Origins: the idea guided Renaissance Italian city-states and the European states system after the Peace of Westphalia (1648); the Treaty of Utrecht (1713) expressly named the balance of power as an aim.

Britain as balancer: for much of the eighteenth and nineteenth centuries Britain acted as the 'holder of the balance', opposing whichever continental power threatened to dominate Europe.

Concert of Europe: after the Congress of Vienna (1815), the great powers managed the balance through regular consultation, and Europe avoided a general war for about a century despite conflicts such as the Crimean War (1853 to 1856).

Breakdown: rigid alliances (the Triple Alliance and the Triple Entente) turned a local crisis into the First World War; Wilson blamed balance-of-power politics and promoted collective security instead.

Since 1945: the Cold War produced a bipolar 'balance of terror', followed by US unipolarity after 1991 and today an emerging multipolarity with the rise of China and other powers.

3. Methods of Maintaining the Balance

Alliances and armaments: forming alliances and counter-alliances, and building or reducing armaments; Waltz called these external and internal balancing.

Compensation and buffers: territorial compensation (as in the partitions of Poland, 1772 to 1795), divide and rule, and buffer states (Afghanistan between British India and Russia).

Intervention and the balancer: intervening in the affairs of other states to restore equilibrium, or a holder of the balance shifting sides.

Soft balancing: T.V. Paul and Robert Pape (2005) described states constraining a dominant power through diplomacy, institutions and limited alignments rather than military alliances.

4. Theories and Debates

Waltz: balancing is a recurring tendency produced by anarchy; whatever states intend, balances form again and again.

Balance of threat: Stephen Walt, The Origins of Alliances (1987), argued that states balance against threats, not power alone, judging aggregate power, geographic proximity, offensive capabilities and perceived offensive intentions.

Bandwagoning: some states join the stronger side instead of balancing; Randall Schweller, 'Bandwagoning for Profit' (1994), argued that revisionist states bandwagon to gain.

Power transition: A.F.K. Organski, World Politics (1958), argued that war is most likely when a dissatisfied rising power approaches parity with the dominant power, so preponderance, not balance, keeps peace. Robert Gilpin, War and Change in World Politics (1981), linked hegemonic decline to hegemonic war.

Thucydides Trap: Graham Allison, Destined for War (2017), found that in twelve of sixteen cases over five hundred years in which a rising power challenged a ruling power, the result was war, and applied this to US-China rivalry.

Unipolarity puzzle: William Wohlforth, 'The Stability of a Unipolar World' (1999), explained why no coalition formed to balance the USA after the Cold War.

Critiques: the concept is vague; power is hard to measure; balancing has often meant war rather than peace; it assumes flexible, rational states and ignores ideology and domestic politics; and nuclear weapons changed its logic.

5. Deterrence: Concept and Strategies

Meaning: deterrence is persuading an adversary not to act by convincing it that the costs will outweigh the benefits. Thomas Schelling, Arms and Influence (1966), contrasted it with compellence, which uses threats to make an adversary do something.

Punishment and denial: Glenn Snyder, Deterrence and Defense (1961), distinguished deterrence by punishment (threatening retaliation) from deterrence by denial (making the attack unlikely to succeed).

Requirements: capability, credibility and communication: the threat must be possible, believable and clearly signalled.

Brodie: Bernard Brodie, The Absolute Weapon (1946), wrote that until then the chief purpose of the military had been to win wars, and from now on its chief purpose must be to avert them.

US doctrines: massive retaliation (John Foster Dulles, January 1954), flexible response (the Kennedy administration, adopted by NATO in 1967) and mutual assured destruction, resting on a triad of land, sea and air forces.

Second-strike capability: Albert Wohlstetter, 'The Delicate Balance of Terror' (Foreign Affairs, 1959), showed that deterrence depends on forces that can survive a first strike and still retaliate.

Strategists of the nuclear age: Schelling, The Strategy of Conflict (1960), analysed deterrence as bargaining and the 'threat that leaves something to chance'; Herman Kahn, On Thermonuclear War (1960) and On Escalation (1965), set out the escalation ladder.

Extended deterrence: a nuclear power's promise to defend allies, such as the US nuclear umbrella over NATO, Japan and South Korea.

Stability-instability paradox: Glenn Snyder (1965) argued that stability at the nuclear level can encourage instability at lower levels of conflict, since each side assumes the other will not escalate to nuclear war.

6. Debates on Deterrence

Waltz versus Sagan: in The Spread of Nuclear Weapons: A Debate (1995), Waltz argued that 'more may be better' because nuclear weapons make states cautious; Scott Sagan replied that organisational failures and military biases make proliferation dangerous.

Limits: deterrence assumes rational actors and clear communication, yet the Cuban Missile Crisis (October 1962) and false alarms showed the risk of miscalculation; terrorist groups without territory are hard to deter; and the morality of threatening mass destruction is contested.

Nuclear taboo and arms control: Nina Tannenwald, The Nuclear Taboo (2007), argued that a normative prohibition has also kept nuclear weapons unused. Arms control includes the NPT (1968), the CTBT (1996, not in force) and the US-Russia New START treaty (2010), whose implementation Russia suspended in February 2023.

New domains: deterrence is now debated for cyber attacks, space and conventional precision strikes, where attribution and credibility are harder.

7. Indian Context

Kautilya's mandala: the Arthashastra describes a circle of states around the vijigishu (would-be conqueror): the ari (enemy), the mitra (friend), the enemy's friend, the madhyama (middle king) and the udasina (neutral king), an early theory of balancing.

Balancing in 1971: after Kissinger's secret visit to Beijing (July 1971) signalled US-China alignment with Pakistan, India signed the Indo-Soviet Treaty of Peace, Friendship and Cooperation (August 1971).

Balancing China today: India works with the Quad (revived in 2017; first leaders' summit, held virtually, in March 2021) and Indo-Pacific partners, while keeping ties with Russia and engaging in BRICS and the SCO, a mix of external balancing, soft balancing and strategic autonomy.

Nuclear tests: Pokhran-I (May 1974) was described as a 'peaceful nuclear explosion'; Pokhran-II (11 and 13 May 1998) was followed by Pakistan's tests on 28 and 30 May 1998.

Nuclear doctrine (January 2003): credible minimum deterrence; no first use; retaliation to a first strike will be massive and designed to inflict unacceptable damage; retaliation authorised only by the civilian political leadership through the Nuclear Command Authority; no use against non-nuclear weapon states; and an option of nuclear retaliation against a major biological or chemical attack.

Triad: INS Arihant, India's first nuclear-powered ballistic missile submarine, completed its first deterrence patrol in November 2018, giving India a sea-based second strike.

Stability-instability paradox in South Asia: the Kargil conflict (1999) and cross-border terrorism under the nuclear shadow fit Snyder's paradox. India's responses in 2016, 2019 and 2025 aim to restore deterrence by punishment below the nuclear threshold.

Debate on no first use: in August 2019 Defence Minister Rajnath Singh said that India had strictly followed no first use but that what happens in future depends on circumstances, reviving debate on the doctrine.

8. Using It in the Exam

10-mark answer: define the concept, give one theory or method, state one critique and give one example.

20-mark answer: define; trace history (Utrecht, Concert of Europe, Cold War); explain methods and theories (Waltz, Walt, Organski); assess relevance today; for deterrence explain punishment and denial, second strike and the stability-instability paradox; apply to India; conclude.

Keywords: equilibrium, balancer, balance of threat, soft balancing, power transition, deterrence by denial, second-strike capability, credible minimum deterrence, no first use.

Quotation: Brodie's point that the purpose of military forces in the nuclear age is to avert wars rather than win them (The Absolute Weapon, 1946; paraphrase).

Tip: link the two concepts: nuclear deterrence created a 'balance of terror' that replaced the flexible alliances of the classical balance of power.

1. Transnational Actors: Meaning and Rise

Meaning: transnational actors are non-state actors whose activities cross national borders: multinational corporations (MNCs), international NGOs, advocacy networks, religious bodies, diasporas, terrorist and criminal networks, and global technology platforms.

Challenge to state-centrism: Robert Keohane and Joseph Nye, Transnational Relations and World Politics (first published as a special issue of International Organization in 1971), argued that contacts and coalitions across borders that are not controlled by foreign ministries shape world politics.

Complex interdependence: in Power and Interdependence (1977) they described multiple channels connecting societies, no clear hierarchy among issues (economics can matter as much as security) and a minor role for military force among interdependent states.

Rosenau: James Rosenau, Turbulence in World Politics (1990), described a 'bifurcated' world in which a state-centric world coexists with a multi-centric world of 'sovereignty-free' actors.

Drivers: economic globalisation, cheap communication and the internet, the end of the Cold War and the spread of democracy all expanded space for non-state actors.

2. Types of Transnational Actors

Multinational corporations: control global production and investment; Raymond Vernon, Sovereignty at Bay (1971), examined their challenge to states. Soft regulation includes the UN Global Compact (2000) and the UN Guiding Principles on Business and Human Rights (2011).

International NGOs: the ICRC (1863), Amnesty International (1961), Greenpeace (1971) and Médecins Sans Frontières (1971) monitor states, deliver aid and shape treaties; the International Campaign to Ban Landmines won the 1997 Nobel Peace Prize after the Ottawa Treaty (1997).

Transnational advocacy networks: Margaret Keck and Kathryn Sikkink, Activists Beyond Borders (1998), described the 'boomerang pattern', in which domestic groups blocked at home reach out to foreign allies who then pressure their government from outside.

Epistemic communities: Peter Haas (1992) defined them as networks of experts with shared knowledge and beliefs who shape policy, as scientists did for the Montreal Protocol on ozone (1987) and through the IPCC (1988).

Religious and diaspora actors: churches, religious movements and diasporas mobilise resources and lobby host governments on behalf of homelands.

Violent non-state actors: networks such as Al-Qaeda and ISIS, and transnational organised crime, addressed by the UN Convention against Transnational Organized Crime (Palermo, 2000).

Private and philanthropic power: technology platforms, credit rating agencies and foundations such as the Gates Foundation (a founder of Gavi, the vaccine alliance, in 2000) now shape global rules and agendas.

3. Debates on Transnational Actors

Liberal-pluralist view: transnational actors erode the state's monopoly, enable global governance and form a global civil society (Mary Kaldor, Global Civil Society, 2003).

Realist view: states remain the main actors; transnational actors operate within rules that states set and can be shut down by them.

Marxist view: MNCs are agents of core capital that extract surplus from the periphery and shape state policy in their favour.

Constructivist view: NGOs act as 'norm entrepreneurs'; Martha Finnemore and Kathryn Sikkink (1998) described a norm life cycle of emergence, cascade and internalisation.

Legitimacy problem: many transnational actors are unelected, dominated by the global North and weakly accountable, which raises questions about whose voice they represent.

4. Collective Security: Meaning

Meaning: collective security is a system in which states agree that aggression against any one of them is aggression against all, and commit to respond together; its motto is 'one for all and all for one'.

Different from balance of power and collective defence: balance of power relies on shifting alliances against strong states, while collective security is directed against any aggressor, including a member. Collective defence is an alliance against a known external threat, such as NATO under Article 5 of the Washington Treaty (1949).

Preconditions: Inis Claude, Swords into Plowshares (1956), and others identified the requirements: near-universal membership, agreement on what counts as aggression, willingness to put the common interest above national interest, enough collective power, no state too strong to be restrained, and impartiality.

Origin: the idea draws on Kant and was championed by Woodrow Wilson as an alternative to the balance of power.

Claude's assessment: Claude concluded that these conditions are so demanding that collective security has rarely been practised as theory requires.

5. Collective Security in Practice

League Covenant: Article 10 obliged members to respect and preserve each other's territorial integrity and political independence; Article 16 provided sanctions against a member that resorted to war in breach of the Covenant.

League failures: it did little against Japan in Manchuria (1931), imposed sanctions on Italy over Abyssinia (1935 to 1936) that excluded oil, and lost Germany, Japan and Italy as members; the USA never joined.

UN Charter: Article 2(4) prohibits the threat or use of force. Chapter VII lets the Security Council determine threats to peace (Article 39), impose non-military measures (Article 41) and authorise military action (Article 42); the agreements to place national forces at the Council's disposal (Article 43) were never concluded, and Article 51 preserves self-defence.

The veto: under Article 27(3) each permanent member can block substantive decisions, so collective security cannot be used against the great powers or their close allies.

Korea and Uniting for Peace: the Council authorised action in Korea in 1950 only because the Soviet Union was boycotting it; the General Assembly's Uniting for Peace resolution 377 (November 1950) allows the Assembly to recommend action when the Council is deadlocked.

Gulf War: Resolution 678 (1990) authorised 'all necessary means' to expel Iraq from Kuwait, the closest case to collective security in practice.

Recent tests: Resolution 1973 on Libya (2011) was criticised for leading to regime change; vetoes blocked action on Syria; after Russia's invasion of Ukraine (February 2022), Russia vetoed a Council draft, and the General Assembly demanded withdrawal in resolution ES-11/1 (March 2022, 141 votes in favour).

6. Peacekeeping as a Substitute

Origin: the first armed UN peacekeeping force, UNEF, was created during the Suez crisis (1956), based on consent of the parties, impartiality and non-use of force except in self-defence.

'Chapter Six and a Half': Secretary-General Dag Hammarskjöld described peacekeeping as lying between peaceful settlement (Chapter VI) and enforcement (Chapter VII).

Evolution: Boutros Boutros-Ghali's An Agenda for Peace (1992) set out preventive diplomacy, peacemaking, peacekeeping and post-conflict peacebuilding, and the Brahimi Report (2000) called for robust mandates and realistic resources.

7. Indian Context

India and collective security: India supports the UN Charter but criticises the selective use of Chapter VII and an unrepresentative Security Council; with Brazil, Germany and Japan it seeks permanent membership as part of the G4.

Peacekeeping record: India is among the largest cumulative contributors of troops to UN peacekeeping. It chaired the Neutral Nations Repatriation Commission in Korea (1953) under General K.S. Thimayya, served in the Congo (1960 to 1964) and deployed the first all-women Formed Police Unit to Liberia (2007).

Lesson of 1948: India's reference of the Kashmir question to the Security Council showed how great-power politics shape collective decisions, which made India cautious about third-party roles.

Ukraine: India abstained on several UN resolutions, called for dialogue and diplomacy, and Prime Minister Modi told President Putin at Samarkand (September 2022) that 'today's era is not of war'.

Regulating transnational actors: the Foreign Contribution (Regulation) Act 2010, amended in 2020, controls foreign funding of NGOs; the Bhopal gas tragedy (1984, Union Carbide) exposed the difficulty of holding MNCs accountable.

Diaspora as an asset: Pravasi Bharatiya Divas (since 2003) engages the diaspora, and Indian-American groups lobbied for the India-US civil nuclear agreement (2005 to 2008).

Terrorist networks: India proposed a Comprehensive Convention on International Terrorism at the UN in 1996 and has pursued listings under the Security Council's 1267 sanctions regime; Masood Azhar was listed in May 2019.

8. Using It in the Exam

10-mark answer: define the concept, give two examples or two conditions, and add one critique or Indian example.

20-mark answer: for transnational actors, define, classify, present liberal, realist, Marxist and constructivist views, and apply to India; for collective security, define, distinguish it from balance of power and collective defence, assess the League and the UN with cases, discuss peacekeeping, and conclude on reform.

Keywords: complex interdependence, sovereignty-free actors, boomerang pattern, epistemic community, norm entrepreneur, collective security, collective defence, Chapter VII, veto, Uniting for Peace.

Quotation: Modi's remark to Putin that 'today's era is not of war' (Samarkand, 2022); Hammarskjöld's description of peacekeeping as 'Chapter Six and a Half'.

Tip: the most common error is to confuse collective security with collective defence; define both in the introduction.

1. Meaning of the World Capitalist Economy

Meaning: a single global system of production, trade and finance organised on capitalist lines (private ownership, markets, profit and wage labour) that links national economies in a hierarchy.

World-economy: Immanuel Wallerstein dated the capitalist world-economy to the long sixteenth century, with core, semi-peripheral and peripheral zones bound by an international division of labour.

Key features: an international division of labour, unequal exchange between regions, cycles of boom and bust, and the dominance of a leading power and its currency.

Birth of IPE: Susan Strange, 'International Economics and International Relations: A Case of Mutual Neglect' (1970), urged that politics and economics be studied together, founding modern international political economy.

Three ideologies: Robert Gilpin, The Political Economy of International Relations (1987), organised the field around liberalism, economic nationalism and Marxism.

2. Perspectives of International Political Economy

Mercantilism and economic nationalism: wealth is a source of power and the state should build national industry. Alexander Hamilton's Report on Manufactures (1791) and Friedrich List's The National System of Political Economy (1841) defended protection of infant industries; Ha-Joon Chang, Kicking Away the Ladder (2002), argued that rich countries grew through protection and now deny it to others.

Liberalism: Adam Smith and David Ricardo (On the Principles of Political Economy and Taxation, 1817, with the theory of comparative advantage) held that free trade benefits all and promotes peace; Hayek and Friedman revived this view in the late twentieth century.

Marxism: Lenin's theory of imperialism, dependency theory and world-systems theory see the world economy as a structure of exploitation of periphery by core.

Hegemonic stability theory: Charles Kindleberger, The World in Depression, 1929-1939 (1973), argued that the Depression was so deep because Britain could no longer lead and the USA would not; an open world economy needs a stabilising hegemon. Gilpin developed the idea, while Keohane, After Hegemony (1984), argued that institutions can sustain cooperation after hegemony declines.

Embedded liberalism: John Ruggie (1982) described the post-war compromise in which states accepted multilateral free trade while keeping room for domestic welfare and full-employment policies.

Casino capitalism: Susan Strange, Casino Capitalism (1986), warned that deregulated global finance had turned the world economy into a gamble with unstable outcomes.

Feminist IPE: scholars have shown how global production relies on women's low-paid work in export zones and on 'global care chains' of migrant domestic workers.

3. Evolution of the World Capitalist Economy

First globalisation and collapse: under Pax Britannica and the gold standard, trade and capital flows grew from about 1870 to 1914; the First World War, the Great Depression and protectionism such as the US Smoot-Hawley Tariff (1930) broke the system.

Bretton Woods (July 1944): created the IMF and the International Bank for Reconstruction and Development (World Bank), with fixed exchange rates pegged to the US dollar, which was convertible into gold at 35 dollars an ounce. The General Agreement on Tariffs and Trade (1947) governed trade after the proposed International Trade Organization (Havana Charter, 1948) failed.

End of Bretton Woods: President Nixon suspended the dollar's convertibility into gold on 15 August 1971, major currencies floated from 1973, and the oil shocks of 1973 and 1979 strengthened OPEC.

New International Economic Order: the UN General Assembly's Declaration (May 1974) demanded sovereignty over natural resources, fair commodity prices, technology transfer and reform of the IMF and World Bank; the Charter of Economic Rights and Duties of States followed in December 1974.

Debt and adjustment: the Mexican default (1982) opened the debt crisis, leading to IMF and World Bank structural adjustment and the Washington Consensus (1989).

WTO: the World Trade Organization began on 1 January 1995 (Marrakesh Agreement, 1994) with binding dispute settlement and agreements on services (GATS), intellectual property (TRIPS) and agriculture; the Doha Development Round launched in 2001 has stalled.

Financial crises: the Asian crisis (1997 to 1998) and the Global Financial Crisis (after the collapse of Lehman Brothers in September 2008) led to the first G20 leaders' summit (Washington, November 2008) and the Financial Stability Board.

China's rise: after joining the WTO in 2001 China became the world's largest manufacturer, and its Belt and Road Initiative (2013) extended its economic reach.

Fragmentation: US-China tariffs from 2018, the paralysis of the WTO Appellate Body since December 2019 (the USA blocked new appointments) and supply-chain shocks from Covid-19 and the war in Ukraine have pushed states toward resilience and security over efficiency.

Weaponised interdependence: Henry Farrell and Abraham Newman (2019) showed how states controlling network hubs such as the dollar system and SWIFT use them for coercion, as in the 2022 sanctions on Russia that froze central bank reserves and cut several Russian banks off from SWIFT.

4. Globalisation and the World Economy: Debates

Sovereignty: globalisation constrains national policy (Strange's retreat of the state, Rodrik's trilemma), but states still set rules, sign treaties and impose controls.

Global value chains: GVCs let developing countries join production through specialised tasks, but much of the value is captured at the design and marketing ends, the 'smile curve'.

Inequality: Thomas Piketty, Capital in the Twenty-First Century (English edition 2014), argued that when the return on capital exceeds economic growth, wealth concentrates.

Governance reform: the 2010 IMF quota reform, effective from 2016, raised the share of emerging economies; the OECD-G20 two-pillar agreement (2021) set a 15 percent global minimum corporate tax.

Climate and capitalism: carbon border taxes and green industrial policy raise the question of 'common but differentiated responsibilities' (Rio, 1992) between North and South.

Digital economy: data, platforms and artificial intelligence are concentrated in a few firms and countries, and rules on data flows and digital trade are contested.

Deglobalisation or reglobalisation: trade has not collapsed, but it is being reorganised through friend-shoring, regional blocs and debates over the dominance of the dollar.

5. Indian Context

Founding member: India, though still a colony, attended the Bretton Woods conference (1944), became a founding member of the IMF and World Bank, and was an original contracting party to the GATT (1947).

Voice of the Third World: India helped build UNCTAD (1964) and the G-77, and championed the NIEO and the economic agenda of the Non-Aligned Movement.

From self-reliance to crisis: planned import substitution gave way to strains such as the 1966 devaluation and a large IMF loan in 1981; in 1991 foreign exchange reserves fell to a few weeks of imports, gold was pledged, and an IMF-supported programme accompanied the LPG reforms.

WTO and TRIPS: the Patents (Amendment) Act 2005 introduced product patents while Section 3(d) blocked 'evergreening'; the Supreme Court upheld it in Novartis v Union of India (2013), protecting India's role as a supplier of affordable generic medicines.

Agriculture and food security: India leads developing countries in defending public stockholding for food security and has resisted new binding rules on e-commerce and data flows to keep policy space.

G20 presidency (2023): India hosted the Voice of the Global South Summit (January 2023), secured the African Union's admission as a permanent G20 member in the New Delhi Leaders' Declaration, and joined the announcement of the India-Middle East-Europe Economic Corridor.

Joining value chains: Production Linked Incentive schemes, the semiconductor mission and the 'China plus one' trend aim to integrate India into global manufacturing, while digital public infrastructure such as UPI is offered as a global public good.

Challenges: a modest manufacturing share, a large informal workforce and agrarian distress limit the gains from integration, and India balances openness with strategic autonomy, as in its withdrawal from RCEP (2019).

Indian critical voices: scholars such as Prabhat Patnaik and Jayati Ghosh criticise neoliberal globalisation for squeezing peasants and workers, while Jagdish Bhagwati and Arvind Panagariya defend trade-led growth.

6. Using It in the Exam

10-mark answer: define the world capitalist economy, name one theory (for example, hegemonic stability or world-systems), give one institution or event, and an Indian link.

20-mark answer: define; outline the three perspectives; trace evolution (gold standard, Bretton Woods, NIEO, Washington Consensus, WTO, 2008, fragmentation); analyse debates on globalisation; bring in India's role; conclude on reform of global economic governance.

Keywords: international division of labour, hegemonic stability, embedded liberalism, Bretton Woods, NIEO, Washington Consensus, global value chains, weaponised interdependence.

Quotation: Strange's warning that deregulated finance had turned the world economy into 'casino capitalism' (1986).

Tip: keep this answer focused on the international system and North-South relations, not domestic economics; the comparative responses of countries belong to the comparative politics answer on globalisation.

1. Core ideas: why new approaches emerged

The syllabus lists Idealist, Realist, Marxist, Functionalist and Systems approaches, but from the 1970s the field moved on: neo-liberal institutionalism, constructivism, feminism, critical theory, post-structuralism and post-colonial IR now shape both scholarship and UPSC questions.

Two triggers: growing economic interdependence and transnational actors in the 1970s (oil shocks, the end of the Bretton Woods system, multinational firms) challenged realist state-centrism, and the peaceful end of the Cold War (1989-91), which neither neo-realism nor Marxism predicted, opened space for theories based on ideas and identity.

Rationalist vs reflectivist: Robert Keohane, in his 1988 presidential address to the International Studies Association ('International Institutions: Two Approaches'), divided the field into rationalist theories (neo-realism, neo-liberalism), which take interests as given, and reflectivist theories, which ask how interests and identities are formed.

Third great debate: Yosef Lapid (1989) called the clash between positivism and post-positivism the third debate; it concerns whether IR can be an objective science at all.

2. Neo-liberal institutionalism

Complex interdependence: Robert Keohane and Joseph Nye, Power and Interdependence (1977), described a world with three features: multiple channels connecting societies (interstate, transgovernmental, transnational), no fixed hierarchy of issues (economics and environment can rank with security), and a reduced role for military force among interdependent states.

They distinguished sensitivity (how quickly and how much a change in one country affects another) from vulnerability (the cost of adjusting to that change), showing that interdependence is often asymmetric and can itself be a source of power.

Keohane's After Hegemony (1984) accepted the neo-realist premises of anarchy and rational, self-interested states, but argued that cooperation can survive the decline of a hegemon because institutions and regimes make it rational.

Institutions help by reducing transaction costs, supplying information, monitoring compliance, linking issues and lengthening the shadow of the future, an idea drawn from Robert Axelrod's The Evolution of Cooperation (1984) on repeated Prisoner's Dilemma games.

Regimes: Stephen Krasner (1982) defined them as sets of implicit or explicit principles, norms, rules and decision-making procedures around which actors' expectations converge in a given issue area; examples are the GATT/WTO trade regime and the nuclear non-proliferation regime.

Absolute gains: states care mainly about how much they gain, not about whether others gain more, so mutually beneficial deals are possible.

Nye later added soft power (Bound to Lead, 1990; Soft Power, 2004): the ability to get what you want through attraction rather than coercion or payment.

3. The neo-neo debate

The debate between neo-realists (Waltz, Grieco, Mearsheimer) and neo-liberal institutionalists (Keohane, Axelrod) was collected in David Baldwin (ed.), Neorealism and Neoliberalism: The Contemporary Debate (1993).

Shared ground: both are rationalist, state-centric and accept anarchy, which is why Ole Waever described the outcome as a neo-neo synthesis.

Relative vs absolute gains: Joseph Grieco (1988) argued that under anarchy states fear that partners will gain more and later use the advantage against them, so cooperation is harder than liberals think.

Role of institutions: John Mearsheimer, 'The False Promise of International Institutions' (1994-95), held that institutions merely reflect the distribution of power; liberals reply that they have independent effects, as in the WTO dispute settlement system.

Priorities and intentions: neo-realists stress security and capabilities; neo-liberals stress economic welfare and intentions, and see cheating rather than survival as the main obstacle to cooperation.

Did neo-liberalism lighten neo-realism's dark view? Yes, in showing that institutions can produce sustained cooperation even under anarchy; but only partly, because it accepted most of realism's assumptions and says little about security issues where relative gains dominate.

4. Constructivism

Core idea: the structures of international politics are social as well as material; shared ideas, norms and identities shape what states want and how they act. Nicholas Onuf introduced the term in World of Our Making (1989).

Wendt: Alexander Wendt, 'Anarchy is What States Make of It' (International Organization, 1992), argued that self-help and power politics do not follow logically from anarchy but are produced by how states interact and see each other.

In Social Theory of International Politics (1999) Wendt described three cultures of anarchy: Hobbesian (others as enemies), Lockean (others as rivals who accept each other's existence) and Kantian (others as friends, as in a security community).

Wendt's own illustration: 500 British nuclear weapons are less threatening to the United States than 5 North Korean ones, because the meaning of power depends on the relationship, not on the weapons alone.

Agent and structure are mutually constituted: states create norms through practice, and norms in turn shape state identities and interests.

Norms: Martha Finnemore and Kathryn Sikkink (1998) described a norm life cycle of emergence (led by norm entrepreneurs), cascade and internalisation; Peter Katzenstein (ed.), The Culture of National Security (1996), showed how identity shapes security policy.

Securitisation: the Copenhagen School (Barry Buzan, Ole Waever and Jaap de Wilde, Security: A New Framework for Analysis, 1998) treats security as a speech act through which an issue is presented as an existential threat that justifies extraordinary measures.

Critiques: rationalists say constructivism lacks a clear, testable account of when identities change; critical scholars say Wendt's version is too state-centric and close to the mainstream; realists reply that material power still decides outcomes.

5. Feminist approaches

Core question: Cynthia Enloe asked where the women are in international politics. In Bananas, Beaches and Bases: Making Feminist Sense of International Politics (1989) she showed how women's work as plantation labourers, domestic workers, diplomats' wives, workers around military bases and in tourism sustains the international system; her theme is that the personal is international.

Tickner: J. Ann Tickner, in a feminist reformulation of Morgenthau's six principles of realism (1988) and in Gender in International Relations (1992), argued that realism's objective laws reflect a masculine view of power as domination and autonomy, and proposed power as mutual enablement and security as multidimensional.

Carol Cohn ('Sex and Death in the Rational World of Defense Intellectuals', 1987) exposed the gendered, sanitised language of nuclear strategists; Jean Bethke Elshtain (Women and War, 1987) questioned the stereotypes of men as just warriors and women as beautiful souls.

Strands: liberal feminism (inclusion of women in institutions), standpoint feminism (knowledge from women's lives), post-structural feminism (gender as discourse) and post-colonial feminism (Chandra Talpade Mohanty, 'Under Western Eyes', criticised Western feminists for treating Third World women as a single victim category).

Feminist critique of global issues: war and sexual violence, the feminisation of poverty and migrant care labour under globalisation, trafficking, the unequal impact of climate change, and the absence of women at peace tables; UN Security Council Resolution 1325 (2000) on Women, Peace and Security reflects this agenda.

Is it biased? Critics (including Keohane, 1989) asked feminists to turn their insights into a testable research programme, and others call it essentialist for treating women as naturally peaceful. Tickner's reply ('You Just Don't Understand', 1997) was that mainstream IR is itself gender-biased, so a gender lens corrects bias rather than creating it.

6. Critical, post-structural and post-colonial approaches

Robert Cox, 'Social Forces, States and World Orders' (Millennium, 1981): 'Theory is always for someone and for some purpose.' He separated problem-solving theory, which takes the existing order as given and makes it run smoothly, from critical theory, which asks how that order came about and how it can change.

Cox used Gramsci's idea of hegemony: a world order rests on a fit between material capabilities, ideas and institutions, and a dominant power leads through consent as well as force.

Frankfurt School IR: Andrew Linklater (The Transformation of Political Community, 1998) sought more inclusive communities beyond the sovereign state; Ken Booth defined security as emancipation, freeing people from constraints such as war, poverty and oppression.

Post-structuralism: following Foucault and Derrida, Richard Ashley, R.B.J. Walker (Inside/Outside, 1993) and David Campbell (Writing Security, 1992) argue that sovereignty, anarchy and identity are produced by discourse; foreign policy constructs a Self by defining a dangerous Other.

Post-colonial IR: drawing on Edward Said (Orientalism, 1978) and Gayatri Spivak ('Can the Subaltern Speak?', 1988), it shows that IR's founding stories (Westphalia, the balance of power) ignore colonialism, race and the Global South.

Amitav Acharya and Barry Buzan asked why there is no non-Western IR theory (2007); Acharya's call for Global IR (2014) seeks theory built from many world histories, including Kautilya's Arthashastra, non-alignment and Asian regionalism.

7. The debate on objectivity

Positivist claim: Morgenthau held that politics is governed by objective laws rooted in human nature; Waltz built a parsimonious structural theory modelled on economics; both claimed a neutral, scientific standpoint.

Post-positivist reply: facts in IR are shaped by the observer's position, values and interests; theories are produced in particular places (mostly the US and Britain after 1945) and serve particular purposes, as Cox argued.

Evidence of bias: realism's focus on great powers sidelines small states; its image of the rational, autonomous actor is gendered (Tickner); its history is Eurocentric (post-colonial IR); and E.H. Carr had already shown that the harmony of interests preached by satisfied powers served their dominance.

Balanced view: complete objectivity is impossible, but reflexivity, meaning stating one's standpoint, testing claims against evidence and including excluded voices, can reduce bias; Wendt seeks a middle way (via media) between positivism and post-positivism.

8. Indian context

Interdependence and institutions: India's preference for rules-based multilateralism in the WTO (food security, special and differential treatment), climate negotiations (common but differentiated responsibilities) and new bodies such as the International Solar Alliance fits liberal institutionalist reasoning.

Identity and norms: a constructivist reading explains non-alignment and Panchsheel as products of an anti-colonial identity, and strategic autonomy as a lasting norm of Indian foreign policy rather than only a power calculation.

Gender: India sent the first all-women Formed Police Unit to a UN mission (Liberia, 2007), and women now serve as peacekeepers and officers in the armed forces; feminist IR asks how far such inclusion changes policy itself.

Global South voice: post-colonial and Global IR draw on Indian experience, and India presents itself as a voice of the Global South (Voice of the Global South Summits from 2023; the African Union's admission to the G20 during India's presidency in 2023).

9. Using it in the exam

10-mark answer (150 words): define the approach with its thinker and work, give two or three core claims, one critique and one example, preferably Indian or current.

20-mark answer: start with the rationalist-reflectivist divide, explain the approach's assumptions, compare it with realism, add critiques, apply it to a case (India's multilateralism, UNSCR 1325, securitisation of migration) and conclude on its value.

Keywords: complex interdependence, absolute vs relative gains, regimes, intersubjectivity, cultures of anarchy, gender lens, problem-solving vs critical theory, emancipation, Eurocentrism, Global IR.

Quotations: Cox: 'Theory is always for someone and for some purpose'; Wendt's title: 'Anarchy is what states make of it'; Enloe's theme that the personal is international (use as a paraphrase).
