Both policy articles about US post-Cold War foreign policy and the recent rhetoric of US policymakers appears to be slipping back into the language of the ‘arrogance of power’, against which Senator Fulbright warned America in the 1960s. In what follows, the USA's style of foreign policy; its criteria for intervention; its invasion of Panama; its capabilities; its intervention in Bosnia; and the impact of contending theories about changes in the international sphere will be examined with a view to casting some light on how the USA has responded to the world outside its boundaries after the Cold War. Finally, in the light of Senator Fulbright's criticisms of US interventionism in the recent past, the essay draws towards its conclusion by specifically addressing the key questions of the whens, whys and wherefores of US intervention into and exits from international crises. It explores some of the problems posed by continuity and change in the struggle to adjust US foreign policy to a non-Cold War world and examines the wisdom of enthusiastic calls for the US to spread democracy abroad.
