Why are we not factoring in half a dozen low yield nukes lobbed into Seoal and Japan? It would absolutely devastate those highly populated countries. Kim would do that if he felt cornered, I’m sure. We are dealing with a nuclear power here, folks.
I’m not yet sold that the North Koreans have miniaturized a high yield nuke enough to fit on a missile...and I don’t have a lot of faith in their missiles - ability to successfully launch and hit a target. Honestly, I think they’d have better success putting a bomb in a shipping container and smuggling it into a port.
