I think the real reason that airdropping information into North Korea won't help is that it's a slave state held hostage by a ruling family that secures aid for itself with the threat of nuclear Armageddon and the immediate shelling of Seoul. But this is also the reason that the sophistication or lack thereof of their political belief systems is irrelevant: These are not participatory governments.

I would highly recommend The Dictator's Handbook by Bruce Bueno de Mesquita and Alastair Smith for a reset of one's political expectations, especially for countries with resource extraction economies. The mechanics of selectorate theory can be very, very brutal.
