Abstract
Most policy and normative problems with nuclear weaponry arise in the context of extended deterrence; that is, deterrence of attacks on friends or allies of a nuclear power. This article reviews the history and contradictions of post-World War II Western extended deterrent strategy, considers the sources of differences and similarities in the perspectives of the American and West German Catholic bishops on these matters, presents a logical schema of types of deterrent situations, discusses some systematic historical evidence that suggests the utility of nuclear weapons for many of these situations is often exaggerated, and, after reviewing alternative strategies, suggests a role for a very limited “countercombatant” nuclear strategy.
