I'm opposed to nuclear weapons, but: the principle of nuclear non-proliferation - or, in other words, the oligopolization of nuclear strike capability - is more of a subjective and self-serving value held by the US (and some other nuclear powers) than a universal objective truth. If, hypothetically, the US lacked nuclear weapons that other countries had, the acquisition of nuclear capability by a hitherto non-nuclear USA would suddenly be seen as very desirable, and there wouldn't be all this talk about the dangers of proliferation.
