This is very unfortunate... Last thing we need is, another proxy war, especially between China and the U.S. .... because, thats pretty much what it would be.. As much as China see's N. Korea as a liability, they have NO choice but to align with it in ANY case being so adjoined to it.. The logistical issue I see here is, while S. Korean cooler heads prevail, the North is not so made up of cooler heads... If i had to guess, I'd say Kim Jong Ill is about to die, which would explain such a brazen attack.. The selfishness of a dictator only dies with the dictator... It would be a devastating blow to have this escalate for SO many diplomatic reasons.. Sabre rattling is one thing, attacking a nation is a whole different thing...
