This is a great point, but I would submit that the specter of nuclear arms is even more compelling than that of the chemical and biological weapons of the period. The costs are even higher. Has any nuclear armed nation challenged the territorial integrity of another nuclear armed nation? Their proxy fights have been pushed into more and more desolate regions as an ever growing list of nations has fallen under a nuclear umbrella (either their own, or that of an ally).
