Again, nuclear proliferation to islamic countries is justification enough for the U.S. to war with North Korea.

The key to getting China's cooperation with the U.S. is to make it either 1) North Korea gives up its nukes, or 2) Japan as a defense against N. Korea is permitted to get nukes (which would threaten China). And China would move heaven and earth to prevent Japan getting nukes.

North Korea is a state that exists entirely at the whim of the Chinese government. All that is needed is the proper leverage to get China to pull North Korea's strings.
