Survival can be assured in cooperation with international organisations is not a component of the Realist Theory. Realism is a school of thought in international relations theory. The theories of realism revolve around four central propositions: → That the states are the central actors in international politics rather than individuals or international organisations (so the fourth item of the question is incorrect). → That the international political system is anarchic as there is no supranational authority that can enforce rules over the states. → That the actors in the international political system are rational as their actions maximise their own self-interest, and → That all the states desire power so that they can ensure their self-preservation
