In New Perspectives Quarterly, Nobel Laureate Thomas Schelling on nuking Iran and what to do about proliferation.
The US government ought to recognize the taboo is in its favor and not try to develop a new generation of weapons with the aim of making them somehow useful on the battlefield. I’m afraid a lot of people in the Pentagon think, “We are so rich in nuclear weapons, it is a shame not to use them.” They should learn we are so rich in people and infrastructure that we will risk losing that if we encourage others, by our own example, to look positively on the use of nuclear weapons.
That is why, among other things, it is important to get the US Senate to ratify the Comprehensive Test Ban Treaty—not because testing is important, but because that treaty is a pillar of the taboo, another nail in the coffin of the idea of weapons use. The US, above all, should never say nuclear weapons should be used preemptively…
I don’t know if there is any way to stop the Iranians from acquiring nuclear weapons. If they do, we should try to persuade them to declare—as the Indians and Pakistanis have done—that they are for deterrence and defense, not for offensive use.
Further, we should assist the Iranians in making sure custody of their weapons is secure in any time of disruption. In the case of a riot in the streets, will the weapons be safe? Who might grab them in case of civil war?
