International relations (IR), sometimes referred to as international studies and international affairs, is the scientific study of interactions between sovereign states. In a broader sense, it concerns all activities between states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organisations (IGOs), international nongovernmental organisations (INGOs), international legal bodies, and multinational corporations (MNCs). There are several schools of thought within IR, of which the most prominent are realism, liberalism, and constructivism.
International relations theory is the study of international relations (IR) from a theoretical perspective. It seeks to explain causal and constitutive effects in international politics. Ole Holsti describes international relations theories as acting like pairs of coloured sunglasses that allow the wearer to see only salient events relevant to the theory; e.g., an adherent of realism may completely disregard an event that a constructivist might pounce upon as crucial, and vice versa. The three most prominent schools of thought are realism, liberalism, and constructivism.
A state's foreign policy or external policy is its objectives and activities in relation to its interactions with other states, unions, and other political entities, whether bilaterally or through multilateral platforms. The Encyclopedia Britannica notes that a government's foreign policy may be influenced by "domestic considerations, the policies or behaviour of other states, or plans to advance specific geopolitical designs."
Joseph Samuel Nye Jr. is an American political scientist. He and Robert Keohane co-founded the international relations theory of neoliberalism, which they developed in their 1977 book Power and Interdependence. Together with Keohane, he developed the concepts of asymmetrical and complex interdependence. They also explored transnational relations and world politics in an edited volume in the 1970s. More recently, he pioneered the theory of soft power and explained the distinction between it and hard power. His notion of "smart power" became popular with the use of this phrase by members of the Clinton Administration and the Obama Administration.
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, and others have, within a relatively short period, established constructivism as one of the major schools of thought in the field.
International security, also called global 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 is one of the dominant schools of thought in international relations theory, theoretically formalising the Realpolitik statesmanship of early modern Europe. Although a highly diverse body of thought, it is unified by the belief that world politics is always and necessarily a field of conflict among actors pursuing wealth and power. The theories of realism are contrasted by the cooperative ideals of liberalism in international relations.
In international relations, constructivism is a social theory that asserts that significant aspects of international relations are shaped by ideational factors, not simply material 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, anarchy is the idea that the world lacks any supreme authority or sovereign. 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.

In medieval and early modern Western political thought, the respublica or res publica Christiana refers to the international community of Christian peoples and states. As a Latin phrase, res publica Christiana combines Christianity with the originally Roman idea of the res publica to describe this community and its well-being. A single English word with somewhat comparable meaning is Christendom; it is also translated as "the Christian Commonwealth".

A sovereign state or sovereign country, is a political entity represented by one central government that has supreme legitimate authority over territory. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being recognised by other sovereign states. Unrecognised states will often find it difficult to exercise full treaty-making powers or engage in diplomatic relations with other sovereign states.

Classical realism is an international relations theory from the realist school of thought. Realism makes the following assumptions: states are the main actors in the international relations system, there is no supranational international authority, states act in their own self-interest, and states want power for self-preservation. Classical realism can be differentiated from the other forms of realism since it places specific emphasis on human nature and domestic politics as the key factor in explaining state behavior and the causes of inter-state conflict. Classical realist theory adopts a pessimistic view of human nature and argues that humans are not inherently benevolent but instead they are self-interested and act out of fear or aggression. Furthermore, it emphasizes that this human nature is reflected by states in international politics due to international anarchy.
