Unless China cuts off N. Korea....which they won't, AND in the short run would likely make no difference......N. Korea will continue, and the US will likely call their bluff.....its gonna be ugly if that happens, but sooner or later it has to come to a head...and it may as well be sooner....think if the world had stopped Nazi Germany in 1936 as it "armed up"....N. Korea is a danger now and much more dangerous "later" ....so I hope it comes to a head.
