Only North Koreans can change North Korea. Attempting to impose a solution from outside – whether from Beijing, Seoul, or Washington – will just not work. North Koreans are a proud people, even more so after several decades of austerity and government-sponsored nationalism. Like Afghans and Iraqis, they will not take kindly, to say the least, to military invaders. And they know the limitations and leverage points of their society better than any outside political missionary bent on a softer version of regime change.
