Black 5 believes that special forces Colonel David Maxwell's hypothesis about regime change in North Korea will result in another bloody insurgency problem for the United States.
Here is the actual show excerpt on C-Span. Colonel Maxwell's thoughts begin at the 25 minute mark.
I think COL Maxwell is off the mark here for a couple of reasons:
1) The North Korean people themselves want nothing more than to get out from underneath the boot on their throat, as do almost all people in communist countries that bought on to that crap. There will be no support for an insurgency. The Vietnamese left communism of their own accord. As the Chinese are doing now.
2) There is a basic cultural difference between the Middle East and the Far East.
The ideology of militant Islam that exists in Afghanistan does not exist in North Korea. This would not be the case if it was the Philippines or Indonesia. Then the probability of a long insurgency would be high.
