It would have been a good day to launch the needed attack, including taking out all their hardware the top leadership would be gone. Do not make the mistake the US made in Iraq, keep the army in tact and make it a part of the Korean defense force. The whole thing will be over in weeks, south Korea and North Korea will again be one country, all that is need is to look at the German integration and how well it went. Once the treat of punishment including death is removed the people in the North will celebrate. Maybe in 10 years the integration will be done with one vote, in the mean time we will still buy the stuff they make and their own economy will expand. Of course the US will have to be compensated for the stuff they use, but Japan, China and the south will do the heavy lifting as it is there issue.
