 Although political and economic globalization are interconnected and mutually reinforcing, they differ in significant ways. Political globalization refers to changes in the exercise of political power that have resulted from increased transnational engagement. Prior to World War II, the international political system was understood in terms of the so-called Westphalian model. According to this model, political power is exercised primarily through governance at the level of the territorial state. The international political system is comprised of sovereign states, which enjoy a monopoly on political power within their own territories. International treaties govern relations among states; however, states generally cannot legitimately intervene in the domestic affairs of other nations. Thus, when problems, such as famines, genocides, and civil wars arise, they are seen primarily as security issues for individual states, not matters of justice affecting the global community (Fraser 2013).
