Hello aspirants,
Today’s revision capsule of PSIR optional preparation covers Approaches to International Relations. There are four 20-markers, twelve 15-markers, and nie 10-markers from this topic in the last 12 years.
Origins of the Idea
| Year | Term / Author | Key Point |
| 1650s | Richard Zouche – inter gentes | Early “law of nations”. |
| 1780s | Jeremy Bentham – “International” | Coined the English word. |
| 1919 | Aberystwyth Chair (Alfred Zimmern) | First university chair in IR. |
IR as Condition vs Discipline
- Quincy Wright:
- Condition → real-world political, economic, cultural, military dealings among sovereign states & other actors.
- Discipline → systematic, scientific study of those dealings.
Early scepticism: Palmer & Perkins call IR a “loose bundle”; Zimmern “no distinct framework.”
Post-WW II shift: E.H. Carr, Hans Morgenthau inject critical, analytical rigour → IR becomes a bona-fide academic field.
Realism: Generations
| Branch | Core Claim | Prime Names | Signature Texts / Concepts |
| Classical Realism | Power rooted in human nature (egoism, domination). | Thucydides, Kautilya, Machiavelli, Hobbes, E.H. Carr, Hans Morgenthau, Niebuhr | Melian Dialogue; Arthashastra; “ends justify means” ; Leviathan; Twenty Years’ Crisis; Politics Among Nations (6 principles). |
| Structural / Neo-Realism | Anarchic structure of system compels states to seek security. | Kenneth Waltz (Theory of International Politics) | Anarchy, relative gains, security dilemma, bipolar stability. |
| Defensive Realism | States seek enough power for security; over-accumulation backfires. | Waltz, Jack Snyder, Stephen Van Evera | Costly conquest, balancing. |
| Offensive Realism | Best path to survival = maximise power, pursue (regional) hegemony. | John Mearsheimer | “Back-passing, bait-and-bleed, bloodletting”; China’s rise; Thucydides Trap; critique of ‘peaceful rise’. |
| Strategic Realism | Focus on rational coercion & bargaining, not morality. | Thomas Schelling (Strategy of Conflict, Arms & Influence) | Game theory, deterrence, brute force vs coercion, “diplomacy of violence”. |
| Neo-classical Realism | System + domestic intervening variables (leaders’ perceptions, state-society, state capacity). | Gideon Rose, Randall Schweller, Lobell–Ripsman–Taliaferro, Stephen Walt | Status-quo vs revisionist states, extraction capacity, perception of power. |
Realist Keywords
- Anarchy – no central authority.
- Security dilemma (Herz/Jervis).
- Balancing vs Bandwagoning.
- Relative gains.
- Self-help.
- Status-quo / Revisionist / Imperialist states (Morgenthau).
- Thucydides’ Trap – rising vs ruling power tension.
- Brute force vs Coercion (Schelling).
Structural Realism
- Waltz: Units equal in functions; differ in capabilities (power).
- Anarchy + capability distribution ⇒ systemic constraints → limited policy autonomy.
- Market analogy: states ≈ firms; survival the bottom line.
Key Realist Applications
- Cold War “long peace” → bipolar stability (Waltz).
- NATO expansion – Russia/Ukraine crisis → security dilemma (Mearsheimer, Wertheimer).
- US regional hegemony in Western Hemisphere & effort to block Eurasian peers (Mearsheimer).
Major Critiques of Realism
| Critique Line | Scholars / Schools | Points |
| Over-power & war bias | Liberal-institutionalists (Keohane & Nye – Complex Interdependence) | Underplays cooperation, IGOs, UN collective security. |
| State-centrism obsolete | NGO / MNC / Trans-national turn; post-Cold-War pluralists | Non-state actors, climate change, terrorism. |
| Degenerating paradigm | Legro & Moravcsik | Conceptual stretching – “is everybody now a realist?”. |
| Emancipatory / Critical | Ken Booth, Andrew Linklater | Human security > state security, need for emancipation & global justice. |
| International Society | Martin Wight, Henry Kissinger | Must weave realism, rationalism (Grotius), revolutionism (Kant). |
| Constructivist | Alexander Wendt, others | Interests shaped by identities & norms, not just material power. |
| Feminist | J. Ann Tickner | Realism marginalises women & gendered power relations. |

Other Approaches
| INTELLECTUAL ROOTS & CORE PROPOSITIONS | KEY SCHOLARS / TEXTS | LEADING CONCEPTS & MODELS | CANONICAL CRITIQUES | ||||
| I. LIBERAL TRADITION | States/peoples are rational; cooperation can tame anarchy. | Locke Two Treatises – consent & limited rule. Kant Perpetual Peace – republicanism + free-trade pacify. Smith Wealth of Nations – laissez-faire & “invisible hand.” Cobden – trade-as-peace. Angell Great Illusion – war ≠ wealth. Bentham – utilitarian int’l court. Wilson Fourteen Points → League of Nations. | Republican peace · Economic interdependence · Open diplomacy · Self-determination. | Realists: cooperation fragile; secrecy & power trump law. | |||
| Schools of Liberal IR | |||||||
| ➊ Institutionalism | Institutions mitigate anarchy, supply info, lower costs. | Nye & Keohane – complex interdependence. | IGOs/NGOs; supranational rule-making; multiple issue-areas. | Legitimacy deficits; IOs = tools of great-power interest (Realism). | |||
| ➋ Sociological Liberalism | Society-to-society links trump billiard-ball states. | John Burton – cobweb; Karl Deutsch – security community; trends flagged by Rousseau (global media, migration). | Transnationalism; mutual responsiveness; shared values (EU, ASEAN). | Underplays hard-power revivals. | |||
| ➌ (Neo-)Functionalism | “Peace-by-pieces”: technical cooperation spills into politics. | David Mitrany; Ernst Haas – political spill-over, ECSC→EU. | Track-two diplomacy; incremental integration. | Euro-centric, economic bias. | |||
| ➍ Interdependence Liberalism | Trade & finance weave pacific ties. | T. Friedman – “Golden Arches.” Rosecrance – Trading State. | Cost-of-war > gains; MNCs as actors. | Asymmetry lets strong exploit interdependence. | |||
| ➎ Democratic Peace | Democracies (Doyle, Russett, Ray) rarely fight each other. | Dyadic & monadic logics; institutional/cultural constraints. | Used normatively to justify intervention; exceptions & Euro-centrism noted. | ||||
| Neo-liberalism & “Neo-Neo” Debate | Accept anarchy (Waltz) but stress absolute gains. | Keohane After Hegemony; Axelrod Evolution of Cooperation. | Regime theory; issue-linkage; shadow-of-the-future. | Neo-realists: states covet relative gains; institutions epiphenomenal. | |||
| HISTORICAL-MATERIAL LENSES | MAJOR VOICES | STRUCTURES & DYNAMICS | REJOINDERS | ||||
| II. MARXIST / NEO-MARXIST IR | Capitalist world-system, class struggle, imperialism. | Marx-Engels – proletarian internationalism. Lenin Imperialism – export of capital & monopolies. | Core/periphery; conflictual order; historical materialism. | Ignores non-economic motives; over-deterministic (Waltz). | |||
| Dependency & World-System | External linkage breeds under-development. | Frank, Cardoso, Amin, Prebisch, Wallerstein (core / semi / periphery). | Unequal exchange, development of underdevelopment. | Over-emphasis on external factors; East-Asian NICs. | |||
| Neo-Gramscian / Critical | Hegemony via consent & coercion. | Gramsci – civil & political society. Robert Cox – ideas + institutions + material capabilities; “theory is always for someone.” | International organisations as legitimacy machines; counter-hegemonic movements. | Eurocentric; may reify status quo. | |||
| Frankfurt / Habermas / Linklater | Emancipation, communicative action, cosmopolitan citizenship. | Horkheimer, Habermas, Linklater. | Norm-creation through discourse; widening moral community. | Abstract; thin policy prescriptions. | |||
| New Marxism | Globalization as endemic to capitalism. | Justin Rosenberg – Empire of Civil Society; uneven-combined development. | Interplay of economic & political structures. | Complexity dilutes class centrality. | |||
| SOCIETY-CENTRIC & IDEATIONAL TURNS | KEY THEORISTS | SIGNATURE IDEAS | STANDARD OBJECTIONS | |
| III. INTERNATIONAL SOCIETY / ENGLISH SCHOOL | Middle ground: anarchy and order. | Hedley Bull, Martin Wight, R.J. Vincent (Grotius & Kant lineage). | System vs Society; institutions (law, diplomacy, BOP); goals—prevent war, uphold agreements, limit violence; neo-medieval shared sovereignty. | Structure-realists: anarchy timeless; radicals: Eurocentric. |
| IV. SOCIAL CONSTRUCTIVISM | World is socially made; ideas > material givens. | Alexander Wendt (“anarchy is what states make of it”; Hobbesian/Lockean/Kantian cultures). Onuf, Katzenstein, Finnemore, Tannenwald (nuclear taboo). | Intersubjective meanings; identity formation; IOs as norm entrepreneurs. | Realists: norms fragile; deceptive signalling (Krasner, Copeland, Mearsheimer). |
| V. FEMINISM (Empirical · Analytical · Normative) | Gender shapes & is shaped by IR. | Cynthia Enloe, J. Goldstein, Ann Tickner, Ann Towns. | Add women (empirical); deconstruct masculinist concepts (analytical); transformative equality (normative). Tickner’s reformulation of Morgenthau; “protection myth”; bottom-up human security. | Focus on elites?; integration into mainstream still patchy. |
| VI. POST-COLONIALISM | Power/knowledge nexus; de-centring the West. | Edward Said Orientalism; John Hobson (Eurocentrism); Doty, Winter, Laffey & Weldes, Sabaratnam, Bhambra, Shilliam, Bhabha, Spivak, Fanon. | Hierarchical discourse; racial capitalism (Cox, Robinson); case studies—US-Philippines, “asymmetric war”, Cuba, Brexit. | Language barriers; risk of relativism; engagement with IR still uneven. |
Cross-Theory
- Actors → States, classes, transnational networks, genders, “subalterns.”
- Structures → Anarchy, capitalism, hegemony, norms, patriarchy, Eurocentric discourse.
- Drivers of Change → Institutions & interdependence (liberals), crises & class struggle (Marxists), dialogue & learning (constructivists / critical / feminist), decolonising knowledge (post-colonial).
- Security Conceptions → Military balance (realist), liberal-institutional collective security, democratic peace, human emancipation, gendered & everyday security.
