NATO and Extended Deterrence in a Multinuclear World

摘要

Concerns about nuclear proliferation have led to a new wave of enthusiasm for far-reaching nuclear disarmament schemes. According to their proponents, the United States must take the lead in generating a new global disarmament dynamic, including withdrawing the remaining U.S. tactical nuclear weapons from Europe. Such a step will not spell the end of extended deterrence, yet its drawbacks would far outweigh its gains. While achieving little in terms of relaunching disarmament, it would weaken nuclear sharing as an important achievement of managing alliance security. In an emerging multinuclear strategic environment, maintaining a visible nuclear bond between the United States and its NATO allies is not a Cold War relic, but a sensible and nonprovocative means of both deterrence and nonproliferation.
