Abstract
Nuclear deterrence has recently come under attack from many quarters. And philosophers, no less than others, have participated in the attack. The philosophical attacks have come both from consequentialists and deontologists. Deterrence has also, of course, found its defenders, but the latter have tended to be consequentialist or contractarian. I have not yet seen what I take to be a wholly adequate deontological defense of nuclear deterrence. In this essay, I attempt to make such a defense.
