Can Deterrence be Moral?: A Review Discussion

CAN DETERRENCE BE MORAL? A Review Discussion I HE AUTHORS OF A RECENT BOOK on the subject of nuclear deterrence 1 contend that the United States' nuclear deterrence policy is immoral because its credibility ultimately depends upon U.S. willingness to kill directly and intentionally innocent non-combatants, either in attacks on some cities to establish intra-war deterrence, or in final massive retaliation in response to an all-out Soviet attack. The moral principle the authors use for reaching their conclusion is the inviolability of non-combatants to direct attack which was reaffirmed at Vatican II: " Any act of war aimed indiscriminately at destruction of entire cities or extensive areas along with their population is a crime against God and against man himself. It merits unequiv;ocal and unhesitating condemnation ." The empirical evidence the authors use to assess the morality of U.S. nuclear deterrence policy against this moral principle are statements by officials from several administrations , from Kennedy's through Reagan's, from Secretary of Defense MacNamara's statement that" U.S. strategic weapons were being placed in a configuration such that (Soviet) cities could either be spared or destroyed '', through Secretary of Defense Weil1!berger's assertion that ". . . our fo11ces can and will deny them their objectives at whatever level of nuclear conflict they (the Soviets) contemplate". However, the authors' conclusion that U.S. nuclear deterrence policy is immoral because it violates the just war cri1 Nualear Deterrenae: Morality and ReaUsm. By John M.

MURPHY terion of discrimination differs from that reached by the American Catholic bishops in their Pastoral Letter on War and Peace: This complex question has always produced a variety of responses, official and unofficial in character. The NCCB Committee has received a series of statements of clarification of policy from U.S. government officials. Essentially these statements declare that it is not U.S. strategic policy to target the Soviet civilian population as such or to use nuclear weapons deliberately for the purpose of destroying civilian population centers. These statements respond , in principle at least, to one moral criterion for assessing deterrence policy: the immunity of non-combatants from direct attack either by conventional or nuclear weapons. (The Challenge of Peace, Para. 179) The bishops point out, however, that Administration statements : do not address or resolve another very troublesome moral problem namely, that an attack on military targets or militarily significant industrial targets could involve " indirect " (i.e., unintended) but massive civilian casualties... and that: In our consultations, administration officials readily admitted that, while they hoped any nuclear exchange could be kept limited, they were prepared to retaliate in a massive way if necessary. They also agreed that once any substantial numbers of weapons were used, the civilian casualty levels would quickly become catastrophic , and that even with attacks limited to "military" targets, the number of deaths in a substantial exchange would be almost indistinguishable from what might occur if civilian centers had been deliberately and directly struck. These possibilities pose a different moral question and are to be judged by a different moral criterion: the principle of proportionality. (The Challenge of Peace, Para. 180) Thus, the bishop's objection to U.S. nuclear ·detenent policy is that it violates the just war criterion of proportionality. Note, however, this critical distinction: while the conclusion the bishops state after applying the princip1e of discrimination to U.S. nuclear deterrent policy is an example of a morally CAN DETERRENCE BE MORAL? binding statement, the conclusion they reach after applying the principle of proportionality is an example of a prudential judgment. As such, it is "... based on specific circumstances which can change or which can he interpreted differently by people of good will " and "the moral judgments that we make in specific cases, while not binding in conscience, are to he given serious attention and consideration by Catholics as they determine whether their moral judgments are consistent with the Gospel". (emphasis added) (The ChaJ,lenge of Peace, Para. IO) We, therefore, do not believe that the authors have...
