At a time when events are overtaking many publications, these articles selected from International Security provide up-to-date and comprehensive analyses of American national security strategy in the post-Cold War world.Addressing future U.S. relations with its Cold War allies as well as with its former foes, contributions take up such major issues as overall strategic options, security in the new Europe, relations with the former Soviet Union, U.S.-Japan relations, and threats in the Third World, particularly proliferation.Essays in the first section examine the broad options that the United States has now that it no longer confronts a Soviet threat. They discuss such questions as what threats the United States now confronts, what values and interests it should pursue, whether it should play a diminished role in world politics, and what lessons can be drawn from the past. Essays in the second section look at important dimensions of U.S. strategy, including assuring security in Europe, relations with the former Soviet Union, and U.S. interests in the Third World.With its explicit focus on what course the United States should pursue in the post-Cold War world, America's Strategy in a Changing World serves as a companion volume to The Cold War and After, which drew on important theories in international relations to explain and predict the pattern of world politics.
