Neorealism (international relations) in the context of "Theory of International Politics"

In international relations, intergovernmentalism treats states (and national governments in particular) as the primary actors in the integration process. Intergovernmentalist approaches claim to be able to explain both periods of radical change in the European Union because of converging governmental preferences and periods of inertia because of diverging national interests.

Intergovernmentalism is distinguishable from realism and neorealism because it recognized the significance of institutionalisation in international politics and the impact of domestic politics upon governmental preferences.

In international relations theory, the concept of anarchy is the idea that the world lacks any supreme authority or sovereignty. In an anarchic state, there is no hierarchically superior, coercive power that can resolve disputes, enforce law, or order the system of international politics. In international relations, anarchy is widely accepted as the starting point for international relations theory.

International relations generally does not understand "anarchy" as signifying a world in chaos, disorder, or conflict; rather, it is possible for ordered relations between states to be maintained in an anarchic international system. Anarchy provides foundations for realist, neorealist, and neoliberal, and constructivist paradigms of international relations. Liberal theory disputes that anarchy is a fundamental condition of the international system. On the other hand, constructivist scholar Alexander Wendt argued that "anarchy is what states make of it."

John Joseph Mearsheimer (/ˈmɪərʃaɪmər/; born December 14, 1947) is an American political scientist and international relations scholar. He is the R. Wendell Harrison Distinguished Service Professor of Political Science at the University of Chicago.

Mearsheimer is best known for developing the neorealist (or structural realist) theory of offensive realism, which describes the interaction between great powers as being primarily driven by the rational desire to achieve regional hegemony in an anarchic international system. In accordance with his theory, in the 2001 book The Tragedy of Great Power Politics, Mearsheimer says that China's growing power will likely bring it into conflict with the United States.

Offensive realism is a structural theory in international relations which belongs to the neorealist school of thought and was put forward by the political scholar John Mearsheimer in response to defensive realism. Offensive realism holds that the anarchic nature of the international system is responsible for the promotion of aggressive state behavior in international politics. The theory fundamentally differs from defensive realism by depicting great powers as power-maximizing revisionists privileging buck-passing and self-promotion over balancing strategies in their consistent aim to dominate the international system. The theory brings important alternative contributions for the study and understanding of international relations but remains the subject of criticism.

Kenneth Neal Waltz (/wɔːlts/; June 8, 1924 – May 12, 2013) was an American political scientist who was a member of the faculty at both the University of California, Berkeley, and Columbia University and one of the most prominent scholars in the field of international relations. He was a veteran of both World War II and the Korean War.

Waltz was one of the original founders of neorealism, or structural realism, in international relations theory and later became associated with the school of defensive neorealism. Waltz's theories have been extensively debated within the field of international relations. His 1979 book Theory of International Politics is the most assigned book in International Relations graduate training at U.S. universities.

Liberal institutionalism (or institutional liberalism or neoliberalism) is a theory of international relations that holds that international cooperation between states is feasible and sustainable, and that such cooperation can reduce conflict and competition. Neoliberalism is a revised version of liberalism. Alongside neorealism, liberal institutionalism is one of the two most influential contemporary approaches to international relations.

In contrast to neorealist scholarship (which is skeptical of prospects for sustainable cooperation), liberal institutionalism argues that cooperation is feasible and sustainable. Liberal institutionalists highlight the role of international institutions and regimes in facilitating cooperation between states. Robert Keohane's 1984 book After Hegemony used insights from the new institutional economics to argue that the international system could remain stable in the absence of a hegemon, thus rebutting hegemonic stability theory.

"Anarchy Is What States Make of It: The Social Construction of Power Politics" is a journal article by Alexander Wendt published in International Organization in 1992 that outlines a constructivist approach to international relations theory.

Wendt argues that anarchy is not inherent in the international system in the way in which other schools of international relations theory envision it, but rather it is a construct of the nation-states in the system. At the core of constructivist thought is the idea that many core aspects of international relations are socially constructed (they are given their form by ongoing processes of social practice and interaction), rather than inherent, contrary to the assumptions of neorealism and neoliberalism. According to Wendt, the two basic tenets of constructivism are:
