Threat from the DPRK (North Korea)

[Kinser79]

The problem Mr. Horn, is that Kim is rational. There is no "western sense" to whether one is rational or not. In fact I would say that all three have been particularly cold and calculating in their world wide actions. Kim Jong-Il and Kim Jong-Un in particular. Il-Sung mostly lived on foreign aid from the USSR and China.

As for shelling Seoul, I say let him. It means the ROK will have no choice but to fight, and eventually reunify the penensula. They don't have much interest in doing that right now because modernizing the North would be a huge drag on their economy much like Germany experienced in their reunification.

Vietnam not so much. Neither the south or the north were particularly developed at the time.
