Are the countries on our side self-aware of the roles they are playing? Are they giving thought to how to transform the situation? One element George Friedman did not mention is that South Korea took a look at West Germany's absorption of East Germany and its expense, and they decided that they did not want to spend that kind of money.
One obvious transforming intervention we could do is to "infiltrate" a large number of boats to North Korea, with enough additional help to encourage a boat-person exodus. So many people leaving could cause an East German style collapse of the regime.
