Neorealism (international relations)

Neorealism or structural realism is a theory of international relations that emphasizes the role of power politics in international relations, sees competition and conflict as enduring features and sees limited potential for cooperation. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to engage in power politics.

It was first outlined by Kenneth Waltz in his 1979 book Theory of International Politics. Alongside neoliberalism, neorealism is one of the two most influential contemporary approaches (although neoconservatism should be mentioned, at least for approaches in the United States) to international relations; the two perspectives dominated international relations theory from the 1960s to the 1990s.

Neorealism emerged from the North American discipline of political science, and reformulates the classical realist tradition of E. H. Carr, Hans Morgenthau, George Kennan, and Reinhold Niebuhr. Neorealism is subdivided into defensive and offensive neorealism.
