I suspect if the Americans attack the North Koreans, it will cement a new anti-American axis that will include China, Japan and South Korea - as the Chinese help the Japanese and South Koreans recover from the consequences of the Americans initiating hostilities without the blessings of their current allies. The North Korean military problem may get solved, but only at the expense of horrendous new problems much worse than now. It seems to me, that countries who already have nuclear weapons need to deeply consider how it is that others aren't justified to want to join the club? Our American friends, of all people, should be sympathetic to the idea of everyone being armed to the teeth. Or maybe the real answer is to initiate a serious effort to ban ALL of EVERYONE's nuclear weapons. But that doesn't seem to have occurred to the diplomatic genius' yet.
