Security dilemmaIn international relations, the security dilemma (also referred to as the spiral model) is when the increase in one state's security (such as increasing its military strength) leads other states to fear for their own security (because they do not know if the security-increasing state intends to use its growing military for offensive purposes). 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.
International relations theoryInternational 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 policyA state's foreign policy or external policy (as opposed to internal or domestic 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.
Power politicsPower politics is a theory of power in international relations which contends that distributions of power and national interests, or changes to those distributions, are fundamental causes of war and of system stability. The concept of power politics provides a way of understanding systems of international relations: in this view, states compete for the world's limited resources, and it is to an individual state's advantage to be manifestly able to harm others.
Democratic peace theoryProponents of "democratic peace theory" argue that both liberal and republican forms of democracy are hesitant to engage in armed conflict with other identified democracies. Different advocates of this theory suggest that several factors are responsible for motivating peace between democratic states. Individual theorists maintain "monadic" forms of this theory (democracies are in general more peaceful in their international relations); "dyadic" forms of this theory (democracies do not go to war with other democracies); and "systemic" forms of this theory (more democratic states in the international system makes the international system more peaceful).
Balance of power (international relations)The balance of power theory in international relations suggests that states may secure their survival by preventing any one state from gaining enough military power to dominate all others. If one state becomes much stronger, the theory predicts it will take advantage of its weaker neighbors, thereby driving them to unite in a defensive coalition. Some realists maintain that a balance-of-power system is more stable than one with a dominant state, as aggression is unprofitable when there is equilibrium of power between rival coalitions.
International relationsInternational Relations (IR) are the interactions among sovereign states. The scientific study of those interactions is called international studies, international politics, or international affairs. In a broader sense, it 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).
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.
Anarchy (international relations)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.
Liberalism (international relations)Liberalism is a school of thought within international relations theory which revolves around three interrelated principles: Rejection of power politics as the only possible outcome of international relations; it questions security/warfare principles of realism Mutual benefits and international cooperation The role of international organizations and nongovernmental actors in shaping state preferences and policy choices This school of thought emphasizes three factors that encourage more cooperation and less c
Grand strategyGrand strategy or high strategy is a state's strategy of how means (military and nonmilitary) can be used to advance and achieve national interests in the long-term. Issues of grand strategy typically include the choice of military doctrine, force structure and alliances, as well as economic relations, diplomatic behavior, and methods to extract or mobilize resources.
Classical realism (international relations)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 differs from other forms of realism in that 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.
Polarity (international relations)Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes three types of systems: unipolarity, bipolarity, and multipolarity for three or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
Power (international relations)In international relations, power is defined in several different ways. Material definitions of state power emphasize economic and military power. Other definitions of power emphasize the ability to structure and constitute the nature of social relations between actors. Power is an attribute of particular actors in their interactions, as well as a social process that constitutes the social identities and capacities of actors. International relations scholars use the term polarity to describe the distribution of power in the international system.
Constructivism (international relations)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 contrast to other prominent IR approaches and theories (such as realism and rational choice), constructivists see identities and interests of actors as socially constructed and changeable; identities are not static and cannot be exogenously assumed.
