Google "Ceaucescu" for a possible solution.
Little Kim getting the "Ceaucescu" would be the best possible outcome. Then the South will have one heck of a time integrating the North. A poster on this board previously suggested setting up a "puppet regime" after the implosion. Bad term, however, unlike East Germany, where the people did have some access to the West in spite of the Stasi, in the case of North Korea, you are dealing with a people who have been isolated, brainwashed (and thoroughly messed up), and so conditioned to living in what amounts to the perfect police state. The Kim dynasty had outdone Stalin and Mao on this one. It may take a generation or two for the North to be brought up to speed before a full integration can take place.
Of course the North's view of integrating the peninsula would be to launch a bunch of human wave attacks, and wind up turning the entire peninsula into a glass parking lot. But that doesn't matter to Little Kim, the psycho hedgehog. He's safe in his bunker. Or so he hopes.
