If you think China is going to let North Korea destroy its explosive young economy by firing a missile at a US territory and risking a second Korean War... well. You haven't been paying attention to China. They can call that dog to heel at any time. Un could go too far, but it's unlikely. His replacement due to SBIBS (sudden bullet in brain syndrome) could be as swift as his daddies in China want it to be. Think about it for a minute. You think they'd give up our multi-trillion dollar debt to them over Fatty Kim?
