I think the North wants a war, a conventional one at least with the south. I bet they are hedging bets that Bambi won’t do anything to stop a localized conventional war between the two Koreas.
If the Norks use those 10’s of thousands of pieces of artillery they have pointed at Seoul, it would be devastating within a half hour. A non-conventional response may be appropriate under these circumstances. I think the Norks are stupid, but not this crazy. Causing some Iron rain in one of the most densely populated cities in the world would probably make the Haiti earthquake look like a cakewalk.
Yes, it’s that serious and that’s why we don’t want this escalating.
