Kim Jong-un is not afraid of isolation in the international community nor is he afraid of food shortages. The only thing he fears is the collapse of his dictatorship. When North Korean activists planned to launch balloons carrying 200,000 propaganda leaflets across the heavily militarized border, North Korea responded by threatening to launch a merciless military strike against the anti-North Korean activists. Many of you might think that the leaflets are mere paper, but at the moment, it is one of the most effective way to threaten the current rogue state of North Korea. The leaflet is made not to provoke a conflict but to convey the truth to the north Koreans, and South Korea should not succumb to North Korea's threats and continue with the effort.
