Many nations have tried to play the ferocity game, but the North Koreans added a brilliant and subtle twist to it: being weak. The North Koreans advertised the weakness of their economy, particularly its food insecurity, by various means. This was not done overtly, but by allowing glimpses of its weakness. Given the weakness of its economy and the difficulty of life in North Korea, there was no need to risk trying to undermine the North. It would collapse from its own defects.
This was a double inoculation. The North Koreans' ferocity with weapons whose effectiveness might be questionable, but still pose an unquantifiable threat, caused its enemies to tread carefully. Why risk unleashing its ferocity when its weakness would bring it down? Indeed, a constant debate among Western analysts over the North's power versus its weakness combines to paralyze policymakers.
The North Koreans added a third layer to perfect all of this. They portrayed themselves as crazy, working to appear unpredictable, given to extravagant threats and seeming to welcome a war. Sometimes, they reaffirmed they were crazy via steps like sinking South Korean ships for no apparent reason. As in poker, so with the North: You can play against many sorts of players, from those who truly understand the odds to those who are just playing for fun, but never, ever play poker against a nut. He is totally unpredictable, can't be gamed, and if you play with his head you don't know what will happen.
So long as the North Koreans remained ferocious, weak and crazy, the best thing to do was not irritate them too much and not to worry what kind of government they had. But being weak and crazy was the easy part for the North; maintaining its appearance of ferocity was more challenging. Not only did the North Koreans have to keep increasing their ferocity, they had to avoid increasing it so much that it overpowered the deterrent effect of their weakness and craziness.
A Cautious Nuclear Program
Hence, we have North Korea's eternal nuclear program. It never quite produces a weapon, but no one can be sure whether a weapon might be produced. Due to widespread perceptions that the North Koreans are crazy, it is widely believed they might rush to complete their weapon and go to war at the slightest provocation. The result is the United States, Russia, China, Japan and South Korea holding meetings with North Korea to try to persuade it not to do something crazy.
Interestingly, North Korea never does anything significant and dangerous, or at least not dangerous enough to break the pattern. Since the Korean War, North Korea has carefully calculated its actions, timing them to avoid any move that could force a major reaction. We see this caution built into its nuclear program. After more than a decade of very public ferocity, the North Koreans have not come close to a deliverable weapon. But since if you upset them, they just might, the best bet has been to tread lightly and see if you can gently persuade them not to do something insane.
