Providing a rigorous and objective ethical analysis of nuclear deterrence, this book discusses such issues as the Soviet menace, possible holocaust, and strategic imperatives. At the same time, the authors unmask types of deterrence that they perceive essentially as moral evasions, maintaining that deterrence cannot be bluffing, pure counterforce, the lesser (or greater) evil, or a step towards disarmament. Concluding that deterrence is unjustifiable, this book examines the new questions of conscience that this raises for us all.
