The prospect of millions of dead civilians would justify using nukes on Kim’s artillery positions.
Let’s see NOKO nuclear hardened and tunneled arty positions 30 miles north of Soul, nuclear blast radius of several miles and associated fallout, radiation and concussion wave for low yield weapon which will do little damage - guess we’ll have to step it up a bit -— oh that was Soul? How could we have missed? Some sort of malfunction? The Russians? No? Oh seems the prevailing winds took the radiation and fallout into Northeastern China.
Oh look at all those Chinese troops crossing the border, seems familiar somehow. They do look a bit mad at us ... And here come the Russians from the North. Looks like a pickle to me ...
Very bad idea. Would be start of WWIII.
The Chinese have to do it, we could assist but that all, short of a major nuclear war.
