What to do with North Korea?

North Korea has been in the news lately. Too much of it since it started threatening the U.S. and its allies to have strike us with nukes. Although right now vigorous diplomacy is being applied (along with use of some precautionary military posture), but the threat of the outbreak of the war cannot be ruled out. If it does happen we will continue to be in a state of perpetual war. One of the reason this can be dangerous is the fact that since we don’t have enough intelligence (my previous post has already discussed this) about the intentions of North Koreans, we are just playing blind. Now some of the people are suggesting ways to deal with N.Korea. Some are still urging diplomacy but some are now clamoring for the U.S. to bomb them before it is too late. But would bombing (if possible) solve this problem? and would China and other world powers let this happen because the North Koreans would not sit idle and there would be retaliatory strikes not maybe against the U.S. directly by the South Koreans and maybe Japan and China will feel the pain. So instead of things getting heated up beyond the point of no return, saner voice should prevail and we must find a way out of this nuclear nightmare we are in right now. I cannot suggest anything that will deescalate the situation than to suggest that intense diplomatic efforts (coupled with some concessions) should be pursued and North Korea should be told that it is not in their interest to escalate the situation further than it is right now.
