Publication of the Peace Pastoral, which has been extensively discussed in journals, has had little effect in persuading scholars or commentators on the ethics of nuclear deterrence. A review of the literature generated by The Challenge of Peace provides a survey of the current state of opinion on this question. The bishops, who seek to apply traditional just war categories to the novel situation of the nuclear era, are opposed by representatives of other traditional positions (the arms control community, which tolerates the targeting of civilians, and the “limited war” school, which eschews civilian targets). Two new approaches, likewise opposed to that of the pastoral, set more radical limits to nuclear targeting. All the critics regard the teaching of the pastoral letter, which condemns all militarily meaningful use of the nuclear arsenal, as an anachronistic exercise in the nuclear era.
