Sovereignty: Absolute (Realism) vs. Pooled (Liberalism)
Realists (e.g. John Mearsheimer) argue that sovereignty must remain absolute for states to survive. Sovereignty is a zero-sum asset: once you give it away, you weaken your state.
Liberals (e.g. Francis Fukuyama, Robert Keohane) argue that sovereignty can be pooled or shared to solve collective action problems and increase global governance efficiency.
EU coordinated military aid to Ukraine shows pooled sovereignty in defence decisions.
WHO pandemic treaty talks demonstrate liberal willingness to pool health sovereignty post-COVID.
John Locke (Liberal): sovereignty exists through consent and can be delegated, aligning with liberal pooling of authority.
Point: Actors: State Centric (Realism) vs. Pluralist (Liberalism)
Realists like Kenneth Waltz view the international system as anarchic and composed solely of states, which act in rational self-interest.
Liberals (e.g. Keohane and Nye) view the international system as interdependent, with non state actors playing a key role in cooperation and shaping outcomes.
COP28 featured major corporations, NGOs, and states forming energy transition agreements.
ICC issuing arrest warrant for Putin reflects liberal belief in international law restraining state power.
Thomas Hobbes (Realist-aligned): humans (and thus states) are self-interested and cannot be trusted to cooperate.
Human Nature: Conflictual (Realism) vs. Cooperative (Liberalism)
Realists (e.g. Mearsheimer, Waltz) argue that states mirror human nature: self-help, fear, and mistrust dominate international relations.
Hobbes: pessimistic view of human nature → states must rely on power and dominance.
Liberals, particularly Fukuyama, believe in the potential for progress and peace — arguing that liberal democracy encourages cooperation and the “end of history”.
G7 and G20 cooperation on climate finance and debt restructuring reflects belief in interdependence and mutual gains.
