The end of the Cold War did not return the world to multipolarity. Instead the United States - already materially preeminent - became more so.

No other great power has enjoyed such advantages in material capabilities- military, economic, technological, and geographical. Other states rival the United States in one area or another, but the multifaceted character of American power places it in a category of its own. The sudden collapse of the Soviet Union and its empire, slower economic growth in Japan and Western Europe during the 1990s, and America's outsized military spending have all enhanced these disparities.

It became a "unipolar" state. Not surprisingly, this extraordinary imbalance has triggered global debate. Governments, including that of the United States, are struggling to respond to this peculiar international environment"--
