Nobody wants bombs. The MAD principle still very much rings true. Nobody wants to see Seoul melt, just as much as they don't want to see Pyongyang or San Fran melt.

If you think that a nuclear war with NK will be localized to NK, Japan, SK, and the US, you're severely mistaken. Nuclear war will not stay localized, and even then, we're talking about millions of lives at risk.

That's why the world would all benefit from diplomacy. Nobody is arguing against that. BUT. If it does have to go ballistic, a joint UN war resolution, likely to be lead by the US, would be far less likely to launch a preemptive nuclear strike. The strike would likely be with conventional, non-nuclear weapons. I'm not entirely confident that one could say the same if we let the Kim regime strike the first blow.

There is nothing false in calling a nuclear hegemony that speaks on striking populated city centers of sovereign nations with nuclear weapons a global threat. I feel like that's at least one point we can agree on.
