North Korea is a tough one with no real easy answer. According to Kim Jong Il's son Kim Jong Nam (who now resides in China) the regime is heading to collapse and they only have two options. Keep the status quo which will eventually collapse or Chinese-like reforms which would weaken the regime's grip on the people and probably end up with a total collapse. Either option is frightening, as rogue regimes like that may try to start a war as a last chance to keep their population under control.
