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.
International relations (IR), are the interactions among sovereign states. The scientific study of those interactions is also referred to as international studies, international politics, or international affairs. In a broader sense, the study of IR, in addition to multilateral relations, concerns all activities among states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organizations (IGOs), international nongovernmental organizations (INGOs), international legal bodies, and multinational corporations (MNCs).
International relations theory is the study of international relations (IR) from a theoretical perspective. It seeks to explain behaviors and outcomes in international politics. The three most prominent schools of thought are realism, liberalism and constructivism. Whereas realism and liberalism make broad and specific predictions about international relations, constructivism and rational choice are methodological approaches that focus on certain types of social explanation for phenomena.
Kenneth Neal Waltz 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.
Alexander Wendt is an American political scientist who is one of the core social constructivist researchers in the field of international relations, and a key contributor to quantum social science. Wendt and academics such as Nicholas Onuf, Peter J. Katzenstein, Emanuel Adler, Michael Barnett, Kathryn Sikkink, John Ruggie, Martha Finnemore, Erik Ringmar and others have, within a relatively short period, established constructivism as one of the major schools of thought in the field.
International security is a term which refers to the measures taken by states and international organizations, such as the United Nations, European Union, and others, to ensure mutual survival and safety. These measures include military action and diplomatic agreements such as treaties and conventions. International and national security are invariably linked. International security is national security or state security in the global arena.
Realism, a school of thought in international relations theory, is a theoretical framework that views world politics as an enduring competition among self-interested states vying for power and positioning within an anarchic global system devoid of a centralized authority. It centers on states as rational primary actors navigating a system shaped by power politics, national interest, and a pursuit of security and self-preservation.
Reflectivism is an umbrella label used in International Relations theory for a range of theoretical approaches which oppose rational-choice accounts of social phenomena and positivism generally. The label was popularised by Robert Keohane in his presidential address to the International Studies Association in 1988. The address was entitled "International Institutions: Two Approaches", and contrasted two broad approaches to the study of international institutions. One was "rationalism", the other what Keohane referred to as "reflectivism". Rationalists — including realists, neo-realists, liberals, neo-liberals, and scholars using game-theoretic or expected-utility models — are theorists who adopt the broad theoretical and ontological commitments of rational-choice theory.
In international relations (IR), constructivism is a social theory that asserts that significant aspects of international relations are shaped by ideational factors. The most important ideational factors are those that are collectively held; these collectively held beliefs construct the interests and identities of actors.
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.
The English School of international relations theory maintains that there is a 'society of states' at the international level, despite the condition of anarchy. The English school stands for the conviction that ideas, rather than simply material capabilities, shape the conduct of international politics, and therefore deserve analysis and critique. In this sense it is similar to constructivism, though the English School has its roots more in world history, international law and political theory, and is more open to normative approaches than is generally the case with constructivism.

Neoclassical realism is a theory of international relations and an approach to foreign policy analysis. Initially coined by Gideon Rose in a 1998 World Politics review article, it is a combination of classical realist and neorealist – particularly defensive realist – theories.
Liberal institutionalism 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.
Social Theory of International Politics is a book by Alexander Wendt. It expresses a constructivist approach to the study of international relations and is one of the leading texts within the constructivist approach to international relations scholarship.
In international relations theory, the Great Debates refer to a series of disagreements between international relations scholars. Ashworth describes how the discipline of international relations has been heavily influenced by historical narratives and that "no single idea has been more influential" than the notion that there was a debate between utopian and realist thinking.
