Hyperpower
A hyperpower is a power that is vastly stronger than any potential rivals. Since the end of the Cold War, the United States has been the world's only superpower. Many thus call it a hyperpower, the first global one in world history.The term hyperpower emerged into the language in the 1990s in an effort to explain what had replaced superpower and great power dominance of international relations. The United States has a military strength approaching that of the rest of the world combined. In cultural and economic spheres it is also dominant. Thus some observers have termed this era as one of a hyperpower, with other powers having to learn how to deal with the U.S., while at the same time the States have to learn how to responsibly wield their its power.
Others, such as Samuel P. Huntington, disagree with describing this as a hyperpower period, seeing today rather as a multipolar world. Others see the 21st century as the Pacific century and believe Japan and especially the People's Republic of China will join the United States as great powers.
