Abstract: The United States as a regional hegemon does not want the formation of rival hegemon for herself in other parts of the world. Therefore, after establishing her regional hegemony in Western Hemisphere tried to prevent rival great powers to gain control of Asia and Europe. Some of the great powers like Japan and Germany before 1945 and later the Soviet Union had the potential to become regional hegemony. Presently China after four decades of modernization of the country's vital elements of power is in a position to become a regional hegemon in Asia Pacific in a way that the United States has to reconsider its calculations about China. The present article wants to answer this question why the United States wants to be present in different regions of the world and what factors has affected the United States strategy in Asia Pacific? The underlying hypothesis is that the United States nation security is affected by balance of power in other regions and the presence of the United States in several regions of the world is a response to rise of regional hegemons and the new strategy of the United States in Asia Pacific is a response to rise of China's power. The above hypothesis has been explained with an explanative method.
