There is no justice nor glory to be had in nuclear weapons, but they exist, and need to be contained to as few entities that can use them as possible. Like seriously, the ideal number of nuclear warheads in the world is 0, but that is not the world we were born into.
So I've made peace with mafia boss power politics keeping the number of countries with nuclear weapons on the low end of the spectrum, and for that matter I'd support a much more aggressive approach to that end than we have seen these last 30 years.
