Readying for the Fall of North Korea

Reading among the line, it seems to me that already talks are in progress for the post-Kim North Korea arrangements. The issues to be addressed are:

* Who will deal with the remains of North Korean nuclear facilities?
* Millions will be running for refuge in a short time. They have to be processed, housed, fed and resettled.
* The fall of the regime will cause a vacuum and war between army factions. The transition to a stable government that promises elections must be short.
* The long term political order in the peninsula must be worked out, with participation of the Big Powers and South Korea.

I think a well prepared transition can be fast and will not cause WWIII.
