Saturday Wall St Journal has an op-ed interview with General B.B. Bell, currently US commander in South Korea. The General talks about the various threats from North Korea, the size of their army, the closeness of of North Korean artillery to Seoul, the North Korean nukes, the outgoing South Korean government, just about everything EXCEPT:
Likelihood of the North Korean government loosing control, like the Soviet satellite governments did in eastern Europe at the end of the '80's. If the NK government comes unglued, whose troops will intervene to "maintain order"? The Chinese? The South Koreans? Both? What does China do if North Korea starts reuniting with South Korea?
