Revision summary
Waltzian neorealism pictures anarchy, self-help and relative gains as a dark constant. Keohane and Nye’s neoliberalism keeps anarchy but adds complex interdependence, regimes and absolute gains. Institutions reduce cheating and transaction costs; they do not create a world state. Ukraine, tariffs and health-governance shocks show both residual darkness and institutional repair. The ‘lightening’ is cooperation under anarchy, not the end of power politics.
Model answer
Introduction
Neorealism, in Kenneth Waltz’s Theory of International Politics, is a dark science of anarchy: self-help, relative gains, and the constant possibility of war. Neoliberal institutionalism — Robert Keohane, Joseph Nye, regime theory — does not deny anarchy. It argues that information, iteration and institutions can make cooperation rational. That is the lightening.
Body
The dark view
Waltz stripped classical realism of human nature and kept structure. The international system is anarchic. Units are like units. Security is scarce. States watch relative gains because today’s partner can be tomorrow’s threat. John Mearsheimer later pushed this toward offensive realism: great powers maximise power. The 2022 full-scale war on Ukraine, Pahalgam 2025 and the return of tariff weapons in 2025 all feed the dark reading: force and fear still organise the board.
The neoliberal reply
Keohane’s After Hegemony and Keohane and Nye’s Power and Interdependence argued that under complex interdependence military force is not always the last word, multiple channels connect societies, and issue-areas have their own politics. Regimes — principles, norms, rules and decision procedures — reduce cheating and transaction costs. Absolute gains can suffice when defection is monitored. The WTO, the IAEA, ASEAN’s convening, and even a bruised WHO are illustrations that states lock themselves into rules they could, in theory, smash.
Neoliberalism is not Wilsonian idealism. It is rational-choice institutionalism. Hedley Bull’s anarchical society sits nearby: order without world government. Alexander Wendt later said anarchy is what states make of it; neoliberalism is more cautious, staying with interests and information.
Lightening, not abolition
- The lightening is this: anarchy remains, but it is not a jungle at every hour. Institutions do not replace power; they shape how power is used. When the United States threatens reciprocal tariffs in 2025, neorealists say “I told you so.” Neoliberals reply that the same shock sends India and the EU back to a free-trade agreement table, and that WHO reform talk after a U.S. withdrawal debate is still institutional politics, not a return to 1914. Both can be true. The dark view is the baseline risk. The light view is the daily work of diplomacy.

Conclusion
Neoliberalism lightens neorealism by showing that iterated games, information and regimes make cooperation possible under anarchy. It does not abolish self-help. It makes self-help less lonely.

Is neoliberalism the same as economic neoliberalism?
No. In IR theory it means neoliberal institutionalism, not Thatcher–Reagan market ideology, though the words overlap in student essays.
-
Did neoliberalism refute Waltz?
It qualified him. Most syllabi treat the two as a debate inside rationalism, against constructivism and Marxism.

Discuss the psychological approach to the study of comparative politics.
Approaches to the Study of International Relations
The psychological approach studies personality, attitudes, civic culture and cognition in comparative politics. Lasswell, Adorno, Almond and Verba, Easton and later political psychology are the main lineage. It explains voting, protest, obedience and leadership better than a constitution or a class map alone. Surveys, experiments and psychobiography are typical methods. It is a layer, not a substitute for institutions and political economy.

Explain the non-traditional security threats in the context of food and environmental crises.
Comparative Politics
Non-traditional security covers harms beyond organised military attack: food, environment, health, cyber and crime. Food security is availability, access, utilisation and stability; war, climate and export bans can all break it. Environmental crisis is a threat multiplier through climate, water, disaster and migration. UNDP 1994 human security and Buzan’s sectors supply the theory. These shocks overload the state and also force cooperation through FAO, WHO, Paris and regional reserves.

Discuss the political socialization of open and closed societies.
Politics of Representation and Participation
Political socialisation is the learning of political attitudes, skills and identities. Open societies use competing agents — family, school, parties, plural media — and allow doubt. Closed societies monopolise the story through party, clergy or police and punish dissent. Almond, Verba, Easton, Hyman and Popper supply the vocabulary; Iran, China and backsliding democracies are living cases. No regime is perfectly open or closed; smartphones and migration leak closed systems.
