Abstract

Military deterrence by means of the threat to retaliate if attacked has traditionally involved two intentions—on the one hand, the unconditional intention to deter attack, and, on the other hand, the conditional intention to retaliate if attacked. Nuclear deterrence—that is, military deterrence using nuclear weapons—also involves both intentions, but at the cost of a moral quandary. On the one hand, there is the intention to deter attack in order to preserve peace and freedom. But, on the other hand, there is the intention to retaliate with weapons that would most likely massacre millions of innocent persons. How can the intention to deter attack be morally right, if it presupposes an intention to retaliate if attacked that is morally wrong?
