Although I don’t think for a minute that Pyonyang will launch any nukes the tense situation is still a worry. Since South Korea, and gradually the rest of the world, is treating North Korea’s threats as a bellicose joke and basically ignoring them the leadership in the North risk being regarded as a joke if they don’t back up their threats with some fairly serious action. It would seem that the old game of threats, back down and rewards to the North is not going to be played any more. Therefore, if the North does nothing its leadership will lose face in a big way. Loss of face is a big deal to Koreans as it is to other Asians and to many people generally. This very fact ensures that the situation will remain dangerous.
