Based on that I'm actually surprised SK basically adheres to the rules. I"m pretty sure though that a determined effort to overthrow NK by sneakier means would move the needle a lot. E.g. making small scale incursions, or military maneuvers that 'mistakenly'cross the border by about 10 km, but now we refuse to budge. oops we landed on this small shoreline here, but we'd like to stay. What, You're all starving? We sent a massive peace mission backed by unarmed troops, and lots of food - win hearts and minds. Basically play a constant game of chicken with them, call their bluff and needle the regime whilst taking chunks of territory at the same time. It might soften the border enough and cause so much stress to the regime that it collapses by itself.
