Soft powerIn politics (and particularly in international politics), soft power is the ability to co-opt rather than coerce (in contrast with hard power). It involves shaping the preferences of others through appeal and attraction. A defining feature of soft power is that it is non-coercive; the currency of soft power includes culture, political values, and foreign policies. In 2012, Joseph Nye of Harvard University explained that with soft power, "the best propaganda is not propaganda", further explaining that during the Information Age, "credibility is the scarcest resource".
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.
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.
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.
Sphere of influenceIn the field of international relations, a sphere of influence is a spatial region or concept division over which a state or organization has a level of cultural, economic, military or political exclusivity. While there may be a formal alliance or other treaty obligations between the influenced and influencer, such formal arrangements are not necessary and the influence can often be more of an example of soft power. Similarly, a formal alliance does not necessarily mean that one country lies within another's sphere of influence.
International securityInternational 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. By the end of World War II, a new subject of academic study, security studies, focusing on international security emerged.
Hard powerIn politics, hard power is the use of military and economic means to influence the behavior or interests of other political bodies. This form of political power is often aggressive (coercion), and is most immediately effective when imposed by one political body upon another of less military and/or economic power. Hard power contrasts with soft power, which comes from diplomacy, culture and history. According to Joseph Nye, hard power involves "the ability to use the carrots and sticks of economic and military might to make others follow your will".
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".
Regional powerIn international relations, since the late 20th century, the term "regional power" has been used for a sovereign state that exercises significant power within a given geographical region. States that wield unrivaled power and influence within a region of the world possess regional hegemony. Regional powers shape the polarity of a regional area. Typically, regional powers have capabilities which are important in the region, but do not have capabilities at a global scale. Slightly contrasting definitions differ as to what makes a regional power.
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.
