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 four most prominent schools of thought are realism, liberalism, constructivism, and rational choice. 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.
Foreign policy, also known as external policy, is the set of strategies and actions a state employs in its interactions with other states, unions, and international entities. It encompasses a wide range of objectives, including defense and security, economic benefits, and humanitarian assistance. The formulation of foreign policy is influenced by various factors such as domestic considerations, the behavior of other states, and geopolitical strategies. Historically, the practice of foreign policy has evolved from managing short-term crises to addressing long-term international relations, with diplomatic corps playing a crucial role in its development.
A military alliance is a formal agreement between nations that specifies mutual obligations regarding national security. In the event a nation is attacked, members of the alliance are often obligated to come to their defense regardless if attacked directly. Military alliances can be classified into defense pacts, non-aggression pacts, and ententes. Alliances may be covert or public.
An insurgency is a violent, armed rebellion by small, lightly armed bands who practice guerrilla warfare against a larger authority. The key descriptive feature of insurgency is its asymmetric nature: small irregular forces face a large, well-equipped, regular military force state adversary. Due to this asymmetry, insurgents avoid large-scale direct battles, opting instead to blend in with the civilian population where they gradually expand territorial control and military forces. Insurgency frequently hinges on control of and collaboration with local populations.
Deterrence theory refers to the scholarship and practice of how threats of using force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties. The central problem of deterrence revolves around how to credibly threaten military action or nuclear punishment on the adversary despite its costs to the deterrer. Deterrence in an international relations context is the application of deterrence theory to avoid conflict.
Philip Quincy Wright was an American political scientist based at the University of Chicago known for his pioneering work and expertise in international law, international relations, and security studies.
In international relations, the security dilemma is when the increase in one state's security leads other states to fear for their own security. Consequently, security-increasing measures can lead to tensions, escalation or conflict with one or more other parties, producing an outcome which no party truly desires; a political instance of the prisoner's dilemma.
Economic interdependence is the mutual dependence of the participants in an economic system who trade in order to obtain the products they cannot produce efficiently for themselves. Such trading relationships require that the behavior of a participant affects its trading partners and it would be costly to rupture their relationship. The subject was addressed by A. A. Cournot who wrote: "...but in reality the economic system is a whole in which all of the parts are connected and react on one another. An increase in the income of the producers of commodity A will affect the demands for commodities B, C, etc. and the incomes of their producers, and by its reaction will affect the demand for commodity A." Economic Interdependence is evidently a consequence of the division of labour.
Peace and conflict studies or conflict analysis and resolution is a social science field that identifies and analyzes violent and nonviolent behaviors as well as the structural mechanisms attending conflicts, with a view towards understanding those processes which lead to a more desirable human condition. A variation on this, peace studies (irenology), is an interdisciplinary effort aiming at the prevention, de-escalation, and solution of conflicts by peaceful means, thereby seeking "victory" for all parties involved in the conflict.
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.
World Politics is a quarterly peer-reviewed academic journal covering political science and international relations. It is published by Johns Hopkins University Press on behalf of the Princeton Institute for International and Regional Studies. Before 2003, it was sponsored by Princeton's Center of International Studies and before 1951, by the Yale Institute of International Studies. It was established in 1948. The chair of the editorial committee is Grigore Pop-Eleches.

Monica Duffy Toft is an American international relations scholar. Her research interests include international security and strategy, ethnic and religious violence, civil wars, and the relationship between demography and national security. Among her researches, her theory of indivisible territory explains how certain conflicts turn violent while others not, and when it is likely for a conflict to become a violent. Since 2017 she holds the position of Professor of International Politics at the Fletcher School of Law & Diplomacy at Tufts University, and Director of the Fletcher School's Center for Strategic Studies.
In international relations theory, the bargaining model of war is a method of representing the potential gains and losses and ultimate outcome of war between two actors as a bargaining interaction. A central puzzle that motivates research in this vein is the "inefficiency puzzle of war": why do wars occur when it would be better for all parties involved to reach an agreement that goes short of war? In the bargaining model, war between rational actors is possible due to uncertainty and commitment problems. As a result, provision of reliable information and steps to alleviate commitment problems make war less likely. It is an influential strand of rational choice scholarship in the field of international relations.
Compellence is a form of coercion that attempts to get an actor to change its behavior through threats to use force or the actual use of limited force. Compellence can be more clearly described as "a political-diplomatic strategy that aims to influence an adversary's will or incentive structure. It is a strategy that combines threats of force, and, if necessary, the limited and selective use of force in discrete and controlled increments, in a bargaining strategy that includes positive inducements. The aim is to induce an adversary to comply with one's demands, or to negotiate the most favorable compromise possible, while simultaneously managing the crisis to prevent unwanted military escalation."
Rational choice is a prominent framework in international relations scholarship. Rational choice is not a substantive theory of international politics, but rather a methodological approach that focuses on certain types of social explanation for phenomena. In that sense, it is similar to constructivism, and differs from liberalism and realism, which are substantive theories of world politics. Rationalist analyses have been used to substantiate realist theories, as well as liberal theories of international relations.
In international relations, credibility is the perceived likelihood that a leader or a state follows through on threats and promises that have been made. Credibility is a key component of coercion, as well as the functioning of military alliances. Credibility is related to concepts such as reputation and resolve. Reputation for resolve may be a key component of credibility, but credibility is also highly context-dependent.
In international relations, coercion refers to the imposition of costs by a state on other states and non-state actors to prevent them from taking an action (deterrence) or to compel them to take an action (compellence). Coercion frequently takes the form of threats or the use of limited military force. It is commonly seen as analytically distinct from persuasion, brute force, or full-on war.
