Levels of analysis:Polarity

Polarity
Main article: Polarity (international relations)
Polarity in international relations refers to the arrangement of power within the international system. The concept arose from bipolarity during the Cold War, with the international system dominated by the conflict between two superpowers, and has been applied retrospectively by theorists. However, the term bipolar was notably used by Stalin who said he saw the international system as a bipolar one with two opposing powerbases and ideologies. Consequently, the international system prior to 1945 can be described as multipolar, with power being shared among Great powers.

The collapse of the Soviet Union in 1991 had led to unipolarity, with the United States as a sole superpower, although many refuse to acknowledge the fact. China's continued rapid economic growth (in 2010 it became the world's second-largest economy), combined with the respectable international position they hold within political spheres and the power that the Chinese Government exerts over their people (consisting of the largest population in the world), resulted in debate over whether China is now a superpower or a possible candidate in the future. However, China's strategic force unable of projecting power beyond its region and its nuclear arsenal of 250 warheads (compared to 7700 of the United States[24]) mean that the unipolarity will persist in the policy-relevant future.

Several theories of international relations draw upon the idea of polarity. The balance of power was a concept prevalent in Europe prior to the First World War, the thought being that by balancing power blocs it would create stability and prevent war. Theories of the balance of power gained prominence again during the Cold War, being a central mechanism of Kenneth Waltz's Neorealism. Here, the concepts of balancing (rising in power to counter another) and bandwagonning (siding with another) are developed.

Robert Gilpin's Hegemonic stability theory also draws upon the idea of polarity, specifically the state of unipolarity. Hegemony is the preponderance of power at one pole in the international system, and the theory argues this is a stable configuration because of mutual gains by both the dominant power and others in the international system. This is contrary to many neorealist arguments, particularly made by Kenneth Waltz, stating that the end of the Cold War and the state of unipolarity is an unstable configuration that will inevitably change.

The case of Gilpin proved to be correct and Waltz's article titled "The Stability of a Bipolar World" [25] was followed in 1999 by William Wohlforth's article titled "The Stability of a Unipolar World"[26]

Waltz's thesis can be expressed in power transition theory, which states that it is likely that a great power would challenge a hegemon after a certain period, resulting in a major war. It suggests that while hegemony can control the occurrence of wars, it also results in the creation of one. Its main proponent, A.F.K. Organski, argued this based on the occurrence of previous wars during British, Portuguese, and Dutch hegemony.

Extending the comparative analysis to pre-modern civilizations, Max Ostrovsky[27] agrees that hegemony leads to a major anti-hegemonic war but sometimes only in the very long range and usually the hegemonic power emerges from this war victorious. To prevent the recurrence of anti-hegemonic wars, the hegemonic power subsequently transforms its hegemonic grand strategy into imperial. The hegemonies of Rome and Ch'in resulted in major anti-hegemonic wars in which the hegemonic powers prevailed and established universal empires.
