Has the existence of nuclear weapons transformed the traditional relationship between power and its use in international affairs? If it has, are we then in a period of transition to a new system based on entirely different principles? How would such a transition affect the lives of individuals? A number of writers address these questions in Power and Policy in Transition. The three basic themes of the book are the nature of power, its use in the pursuit of national interests, and the susceptibility to change of the relationship between power and policy. Essays by scholars, professionals, and laymen grapple therein with the uses and abuses of power. The first of three sections addresses the changing nature of power since World War II. The second concentrates on those who either question or disregard the precepts of realism in international politics. The third considers how the changing nature of power in the world challenges American foreign policy.
