My Guess- As Good As Anybody's

[poliphilo]

Kim Jong-un may be an idiot but I can't believe everyone around him is. My guess is he's being egged on in his suicidal belligerence by comrades who want to create an excuse to depose him.  As things are going he'll either get a bloody nose or be forced to back down and then those around him, deeply lamenting, will have to step in and get rid of him  "for the good of the nation". When you've created a personality cult as big as that surrounding the Kim family you have to go to extreme lengths to discredit and then demolish it.
