I think this is highly unlikely. There's simply no point. NK needs nuclear weapons to stave off possible US invasion. They are not crazy people. Crazy people can't create nuclear weapons just to randomly kill people for no reason.

Come on, I have no sympathy for NK's regime, but that's victim blaming.

The threat is "baiting someone into nuclear war" and not "having tens of thousands of nuclear warheads and being ready to use them to kill millions of people"? Give me an effing break mate :)
