60-Second Review
Express reviewA condensed, point-by-point summary of the module, for reviewing right before a test or exam.
- Realism: From Thucydides to Neorealism. Realism traces a line from Thucydides through Morgenthau to Waltz's structural balance-of-power theory.
- Liberalism and Constructivism. From Kant's perpetual peace to Wendt's constructivism, these schools stress cooperation and ideas.
- Critical and Alternative IR Theories. Critical, Marxist, feminist, postcolonial, and poststructuralist theories challenge mainstream IR's assumptions.
- Strategic Interaction: Games, Deterrence, and Power. Game theory, deterrence, alliances, and power transition explain strategic interaction among great powers.
- Foreign Policy Analysis and Global Governance. Foreign policy analysis and global governance examine decision-making, bargaining, and soft power.
- Classical and Critical Geopolitics. Classical geopolitics from Mackinder to Spykman is challenged by critical geopolitics' constructivist critique.
- Security Studies: From State to Human Security. Security studies expanded from state security to securitization and human security debates.
- Methods and the Future of IR Theory. Rational choice, complexity theory, and debates over theoretical pluralism shape IR's methodological future.
