Expert on military strategy and conflict termination analyzes key problems confronting the United States today and in the future in an increasingly unstable world. This provocative study opens with a short history of U.S. security policy during the Cold War that offers new perspectives; considers the significant changes in both U.S. and Russian defense postures and describes new doctrines and strategies that may apply in the future; discusses some of the major problems of nuclear disarmament in a time of proliferation and points to different expert views on current problems and prospects; and then raises basic questions about how the United States can use military persuasion best to cope with the escalation of warfare both between and within states in the future in terms of peacekeeping roles. This work is designed for upper-level undergraduate and graduate students, teachers, and professionals in military studies, international relations, and world history.
