I don't know whether we should all be laughing or holding our head in our hands in global collective horror at the lava flow of threats streaming out of Pyongyang. Either they are masters of tension to an intensity that a horror movie director would envy, or the much more frightening aspect is that it's so hermetically walled in by psychosis and persecution complexes that they will lash out against some imagined slight that only they recognise. 

There's something eerily reminiscent of the last few months before the outbreak of WW 2; every day, the ratchet cranks up another cog. What is it they hope to gain?
