Also China and Russia, though cautious, are certainly cozying up tighter in order to accommodate one anothers need. I don't think they want that relationship disturbed...and they will certainly have a say in how this goes down. Just as they supported the recent restrictions on N.Korea, they could very well stop anything that comes before the UN concerning any warfare there. Still, the US is bound to assist S.Korea and Japan...so not sure they would have to consider the UN at all.....the whole situation is dicey to say the least.
Good points.
