I don't want to see anyone killed, but from what I've been reading SK is part of the problem, they've gone really soft on NK ...
The time has come to put pressure on the key country - China. Quietly tell Beijing that if they don't put the squeeze on North Korea in 60 days the U.S. will place tariffs on all Chinese imports and the tariffs will be increased every 90 days China does not take action. I would also encourage Japan to annouce it's intention to go nuclear. Might as well have Taiwan and South Korea take that step as well.
