Living with a nuclear North Korea could give its leaders the confidence to act more aggressively versus South Korea. It could also, over time, drive both South Korea and Japan, as well as countries farther afield such as Vietnam, to reconsider their non-nuclear postures. The stability of a critical region of the world would suddenly be in doubt.

How can we pressure China on North Korea if China's one of the two largest holders of American debt?

No amount of sanctioning will persuade North Korea to give up nuclear weapons, nor will China step up and solve the problem for us.
