‘No previous generation of statesmen has had to conduct policy in so unknown an environment at the border line of Armageddon’-Henry Kissinger Nuclear weapons pose a unique challenge to American foreign policy and the American president in particular. The choices the president makes with regard to atomic weapons can change the course of human history and affect the lives of billions of people. In this important new work, scholar, teacher, and diplomat James Goodby analyzes how American presidents have confronted the dilemma of nuclear weapons. Drawing on his own involvement in over fifty years of nuclear policy, he explores specific case studies to illustrate the decision making process and the delicate balance between international cooperation and freedom of action, between the rules of behavior and governmental autonomy.
