To the Editors:
In her evaluation of current books on nuclear forces and those that take into consideration them, Jessica Mathews [“The New Nuclear Threat,” NYR, August 20] proceeds from the chilly warfare–period conceptualization involving use by nice powers of chosen parts of their arsenals in a means that may be “clearly signaled…precisely interpreted by the opposite facet, and responded to not in rage or concern however with calm reasonableness.” She doubts that is attainable, for good cause.
Another tackle “restricted” nuclear warfare can be to think about the standpoint of the submit–chilly warfare class of smaller nuclear powers. Their strategic focus is just not lashed to the bigger world competitors of the good powers Dr. Mathews focuses on (as was that of nuclear-armed UK, France, and China throughout the chilly warfare). Their use of nuclear weapons can be restricted by the comparatively few they’ve at their disposal. It isn’t clear that, say, India and Pakistan settle for the chilly warfare–period redline on use of those weapons created by “efficient deterrence, concern of their destructiveness, and a…taboo in opposition to their use” regardless that they likely are nicely conscious of the horrors using such weapons would contain. In a battle involving this dyad or, sometime, the one enmeshing Israel and Iran, the combatants may nicely determine they’re prepared to deal with their restricted numbers of nuclear weapons as treasured, susceptible, probably decisive belongings finest utilized in a primary strike as soon as preventing has begun. Specifically, Pakistan has suffered from India’s numerical superiority in earlier typical wars and will nicely not be prepared to replay this script.
Moderately than pondering by way of deterrence and taboos, smaller nuclear powers may use nuclear weapons like some other weapons. In the course of the warmth of the opening rounds of a brand new warfare they could coldly calculate the counterforce and countervalue choices permitted or precluded by the dimensions and vary of their arsenals, their estimates of their enemy’s capabilities and intentions, and their total technique for no matter they assume constitutes victory. Chances are high that pressures on them to adapt to chilly warfare–period shibboleths concerning nuclear use from the inaptly termed “worldwide group” may not be sufficient to carry them again.
As well as, after all, we must always take into consideration North Korea…

Jessica T. Mathews replies:
Professor Kanin is after all appropriate that the brand new nuclear powers—India, Pakistan, Israel, and North Korea—might imagine in another way about using these weapons than do the unique 5. Importantly, in addition they assume very in another way from each other. India and Pakistan, for instance, are typically thought of the world’s almost definitely nuclear flashpoint. Over time Islamabad, which is quickly enlarging its nuclear arsenal, has explicitly threatened to make use of nuclear weapons in a warfare dealing with India’s overwhelming typical superiority: a coverage of “nuclear first use within the final resort.” These threats are Islamabad’s major means of deterring such a warfare. India’s nuclear forces and doctrine, in contrast, are designed for retaliation after a previous nuclear assault. It’s actually attainable that one or one other of those 4 nations may face circumstances wherein it felt it had no choice apart from to go nuclear. Nevertheless, I doubt that any of them—even North Korea—wouldn’t really feel the large weight of the taboo in opposition to nuclear use and concern the worldwide penalties of crossing the nuclear threshold.
