Long admired as the most comprehensive and accessible survey available, this fourth edition of U. S. Diplomacy Since 1900, formerly entitled American Diplomacy in the Twentieth Century, has been completely revised and updated. Beginning with the Spanish American War and ending with the coming century, the book explains how Americans have thought about foreign affairs over the course of the twentieth century, noting both the changes and continuity of American foreign relations from the turn of the century up through the post-Cold War era. Updated to include the first Clinton administration, this new edition provides balanced coverage of both the Clinton and Bush administrations' efforts to deal with the extraordinary changes in international affairs after the Cold War. The first chapter, "The Setting of American Foreign Policy," has been completely revised, and a new concluding chapter, entitled "Toward the Twenty-First Century," discusses American foreign relations after the Cold War. A revised section on the Reagan administration has also been included and a completely updated selected bibliography provides students with a current guide to the best and the latest scholarship available on U. S. foreign policy.
