12200. U.S. RESPONSIBILITIES AS A SUPERPOWER IN THE POST-COLD WAR ERA. Considers the responsibilities of the U.S. as the world's only remaining Superpower in the post-Cold War era. The analysis begins with a descriptive overview of the foreign policy that the U.S. appears to be adopting in the new era- that of world leadership. Considers two alternative positions, one based on isolationism and the national self-interest, and the other based on the formation of a new bipolarity. The concluding section argues for the adoption of yet a different course for U.S. foreign policy, one which balances the two extremes of international leadership and isolation and is organized around the principles of international diplomacy and economic responsibility. 8 pages, 15 footnotes, 7 bibliographic sources.
