I'm inclined to agree with this- China should be encouraged to invade North Korea. North Korea's unprovoked attack on a South Korean naval ship is as blatant an act of war as anyone's ever seen and it is hard to see how North Korea will be dealt with in the long term without all out war.
It may be difficult to see what China gets out of it, but the DPRK must be destabilising. Perhaps a US withdrawal from the Korean peninsula and Japan would be a carrot to dangle in front of them in return for sorting out the North.
