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.
Pax BritannicaPax Britannica (Latin for "British Peace", modelled after Pax Romana) was the period of relative peace between the great powers during which the British Empire became the global hegemonic power and adopted the role of a "global policeman". Between 1815 and 1914, a period referred to as Britain's "imperial century", around of territory and roughly 400 million people were added to the British Empire. Victory over Napoleonic France left the British without any serious international rival, other than perhaps Russia in Central Asia.
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.
SuperpowerSuperpower describes a state or supranational union that holds a dominant position characterized by the ability to exert influence or project power on a global scale. This is done through the combined means of economic, military, technological, political, and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers.
Realism (international relations)Realism is one of the dominant schools of thought in international relations theory, theoretically formalizing 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. Realists are divided into three classes based on their view of the essential causes of interstate conflict.
United StatesThe United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America and consisting of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations.
HegemonyHegemony (hɪˈdʒɛməni, hɪˈɡɛməni, ˈhɛdʒəmoʊni) is the political, economic, and military predominance of one state over other states. Hegemony can be regional or global. In Ancient Greece (8th BC – AD 6th ), hegemony denoted the politico-military dominance of the hegemon city-state over other city-states. In the 19th century, hegemony denoted the "social or cultural predominance or ascendancy; predominance by one group within a society or milieu" and "a group or regime which exerts undue influence within a society".
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).
Non-Aligned MovementThe Non-Aligned Movement (NAM) is a forum of 120 countries that are not formally aligned with or against any major power bloc. After the United Nations, it is the largest grouping of states worldwide. The movement originated in the aftermath of the Korean War, as an effort by some countries to counterbalance the rapid bi-polarization of the world during the Cold War, whereby two major powers formed blocs and embarked on a policy to pull the rest of the world into their orbits.
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.
Great powerA great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions.
