USA won't be the next-door neighbor to China - so don't worry - What is easily lost in the debacle over and about NK is that when the regime folds, about 17 million people will be "state-less". China is not looking forward to having 17 million more people to feed, clothe, house, healthcare, jobs and everything else all of a sudden. There's a difference between 17 million people who are born over a period of time - now contrast that to 17 million who immediately show up at the doorstep - Big Difference! Should all NKers flow into SK, SK would be bankrupted if they receive no help from the IMF, ECB, Federal Reserve and other monetary agencies. Its a lose-lose situation for everyone.
