Nuclear deterrence deserves rigorous, objective ethical analysis. In providing it, the authors of this book face realities - the Soviet threat, possible nuclear holocausts, strategic imperatives - but they also unmask moral evasions - deterrence cannot be bluff, pure counterforce, the lesser (or greater) evil, or a step towards disarmament. They conclude that the deterrent is unjustifiable and examine the new questions of conscience that this raises for everyone.
