Deterrence stability just doesn’t happen in an arms competition. Deterrence stability is a frame of mind, not a numbers game. It becomes possible only when the competition seems meaningless to at least one adversary. During the Cold War, China faced the enmity of both nuclear superpowers possessing absurd numbers of nuclear weapons and nuclear war-fighting capabilities with a few dozen long-range missiles. Beijing figured that Moscow and Washington wouldn’t attack if there were a reasonable enough chance that they could be incinerated. This proved to be a wise, low cost bet.
Beijing is much richer now and friction with the United States is growing. So, Beijing is building new subs and missiles, including some that can carry more than one warhead. As is the United States and Russia. At some point, the question will again arise as to when enough is enough, and Beijing has a better track record of figuring this out than Washington and Moscow, which can’t help themselves.
“How much is enough?” was one of the foundational questions of nuclear arms control in the 1960s, and arms controllers were sorely disappointed. They won a great battle with a 1972 US-Soviet treaty banning nation-wide defences. In theory, the absence of missile defences was supposed to drain steam out of the offensive competition. Why? Since missiles would have a free ride to their targets, there would be less reason to add to their number. In practice, the prohibition on national missile defences had a barely imperceptible affect on the arms race. The competition to build up missile “counterforce” capabilities – the ability to accurately target opposing forces and military/industrial potential – had sufficient momentum on its own to carry the competition to new heights. Again, damned if you do and damned if you don’t.
Nuclear war-fighting capabilities never make adversaries feel safer and more secure. Pakistan might have already crossed this Rubicon, broadcasting military targets for its longest-(the Nicobar and Andaman Islands) and its shorter-range (counters to India’s Cold Start plans) missiles. India might go down this path as well, despite an early promise after the 1998 tests by foreign minister Jaswant Singh, who wrote in Foreign Affairs that “India shall not engage in an arms race, nor, of course, shall it subscribe to or reinvent the sterile doctrines of the Cold War.” One of these “sterile” doctrines is presumably the pursuit of nuclear war-fighting capabilities by means of counterforce targeting.
Many such promises have long been broken. Pakistani officials declared that they wouldn’t engage in an arms race, as did their Indian counterparts. Pakistani prime minister Nawaz Sharif promised not to block negotiations in Geneva on a fissile material cut-off treaty. Indian heavyweights such as K Subrahmanyam, Jasjit Singh and K Sundarji weighed in with assessments that very few nuclear weapons would be needed for stable deterrence. Sundarji, an adventurous former army chief and unapologetic booster of an Indian bomb, quipped that, for nuclear deterrence, “more is not better if less is adequate”.
