RE: North Korea is the Re
I wouldn't worry to much about Kim and his nukes. He has very few nukes (likely more than, probably no more than eight)and, while he is obviously insane, he has shown no signs of being suicidal. He knows damned well that if he fires a nuke anywhere that North Korea will quickly become a smoking hole in the ground.
He has a long record of using the nuclear threat as a negotiating tactic for increased aid...the more nukes, the more negotiating clout.
This whole thing could likely have been avoided if the US would have negotiated like diplomats instead of trying to bully and threaten. John Bolton holds a lot of responsibility for the positioning of things right now.
