Delving into the concept of America as an empire, this investigation demonstrates how the country has been steadily expanding its control of overseas territories since the turn of the 20th century. By explaining how U.S. military interventionism harms the interests of Americans politically, economically, and militarily and illustrating how the United States--and the world--would be more free, secure, and prosperous if the U.S. government reduced its military involvement overseas, the study explores how rampant imperialism has threatened U.S. security, straining the country's relations with the rest of the world. A thorough and compelling examination of U.S. foreign and domestic security policies, this informed survey maintains a neutral stance by arguing against both liberal and conservative proponents.
