Basically Kim is just posturing (IMHO) to keep him and his country on a world stage, otherwise NK would be off in the wilderness and nobody would be really concerned about it.
Exactly. NK has no intention of attacking SK. They have had 70 years to do so. Either they are the laziest villains in history, or they have never really been serious about taking on American and SK militarily. But, that doesn’t answer the question: people seem to think that NK was threatening nuclear war. Yet, they clearly weren’t, but rather using the “threat” from the US as justification for not signing the nuclear proliferation treaty. What exactly should Trump’s reaction to that be, that will make NK regret their decision?
