China is just watching and will not lift a finger in response to anything. NK itself could be handled by one carrier group and a couple birds from the midwest. Such an opportunity to put an ordered world back together! NK and CHICOM know that AND that Barry O. is 100% certain to let it pass. No tensions, really.
SK wants nothing done because NK artillery would destroy Seoul. I have no interest in a third war when a Saudi/alqeada mole is in the white hut. The same Saudis who have all sorts of controlling investments and deals in all 6 TV networks. They also guy the usurper mole elected on THEIR TV networks.
