It should be of particular concern to us that the beliefs of Muslims pose a special problem for nuclear deterrence. There is little possibility of our having a cold war with an Islamist regime armed with long-range nuclear weapons. A cold war requires that the parties be mutually deterred by the threat of death. Notions of martyrdom and jihad run roughshod over the logic that allowed the United States and the Soviet Union to pass half a century perched, more or less stably, on the brink of Armageddon.
What will we do if an Islamist regime, which grows dewy-eyed at the mere mention of paradise, ever acquires long-range nuclear weaponry? If history is any guide, we will not be sure about where the offending warheads are or what their state of readiness is, and so we will be unable to rely on targeted, conventional weapons to destroy them. In such a situation, the only thing likely to ensure our survival may be a nuclear first strike of our own. Needless to say, this would be an unthinkable crime—as it would kill tens of millions of innocent civilians in a single day—but it may be the only course of action available to us, given what Islamists believe. How would such an unconscionable act of self-defense be perceived by the rest of the Muslim world? It would likely be seen as the first incursion of a genocidal crusade. The horrible irony here is that seeing could make it so: this very perception could plunge us into a state of hot war with any Muslim state that had the capacity to pose a nuclear threat of its own. All of this is perfectly insane, of course: I have just described a plausible scenario in which much of the world’s population could be annihilated on account of religious ideas that belong on the same shelf with Batman, the philosopher’s stone, and unicorns. That it would be a horrible absurdity for so many of us to die for the sake of myth does not mean, however, that it could not happen.
... a hostile regime that is avowedly suicidal acquires long-range nuclear weaponry (i.e. they can hit distant targets like Paris, London, New York, Los Angeles, etc.). Of course, not every Muslim regime would fit this description. For instance, Pakistan already has nuclear weapons... and there is every reason to believe that the people currently in control of these bombs are more pragmatic and less certain of paradise than the Taliban are. The same could be said of Iran, if it acquires nuclear weapons in the near term. But the civilized world (including all the pragmatic Muslims living within it) must finally come to terms with what the ideology of groups like the Taliban, al Qaeda, ISIS, etc. means—because it destroys the logic of deterrence.
