This position made two related claims. On the one hand, it conceded something that had become obvious to many: given the growth of nuclear arsenals, the actual use of nuclear weapons in a full-scale nuclear exchange would be suicidal and hence irrational. But it also contended that despite this-indeed, because of this-the serious threat to use such weapons could well be entirely rational. A threat to use nuclear weapons in massive retaliatory response to their use by others would be rational, so the view held, if it was on balance likely to be both necessary and sufficient for averting this offensive use and hence likely to avert the start of such a suicidal and irrational nuclear exchange.
