Regime Change in North Korea isnt possible because it is a military society, albeit with a monarchy/emperor at the top. One will be replaced by the next. You can't remove the 'bad guys' because they are at least 30% of the entire population. We are stuck with North Korea as it is for a long long time...decades...so we need to talk and work out something better...well, not 'we' in the west...the north and south brothers, and they are blood brothers, need to work out whats best between them...and I expect, as between all kinds of difficult brothers, there will be push and shove and a bit of blood from time to time...but no one else can solve the artificial split in the people of north and south provinces except the people there. Vietnam springs to mind. best to let the boys work out their problems in their own fashion. They were a united country for longer than they have been divided by outsiders. Korea was given full independence by China in the old days of the Dynasties etc and China wont go back on that agreement. China is the only country on earth that has basically good relationships with both South and North Korea, and that is a diplomatic skill the foreign devils from America do need to learn...and then the US needs, mostly, to just go home.
