In reply to toad:
I get the impression that both "leaders" are more than content to keep ratcheting up the threat level with no real intention of going to war. It all helps divert public attention, create fear, cement control and stifle dissent.
That doesn't, of course, prevent events taking on a life of their own. Or perhaps one side (like the kid in the play fight, who cops an accidental elbow to the eye, going bonkers) forgetting that it was all in jest and start twiddling with launch keys.
On the positive side, we are definitely overdue for a drastic global population correction. And perhaps a nuclear catastrophe is just what is needed to convince those in power (and voters in support of Trident) that humanity might be better off without (i.e. "deterrence", which is the only justification for their existence, doesn't work).
So on balance I'm all for it, and my message to Kim-Trump would be "Aw'right mate, lets 'av it then!". Global warming, getting on the property ladder, my pension, Brexit, inequality and the other myriad of concerns I have would probably vanish with more immediate and down-to-earth issues becoming a bit more of a priority. Armageddon could be rather cathartic.
