I have thought long and hard as to what the world can do about it, and the answer is very little, if Kim the Loon wants to play with the big boys, he needs to act like one, not like a spoilt child with a new toy, I think the Chinese are more concerned than they make out as are the Russians, both are sabre rattlers but thats about it, they know that if either start a war it will be the end of the world, but the Loon from the North is new to the club and as yet does not know the rules, only time will tell if he is going to piss off Trump enough for that idiot to try and take the Loon out.
SO what happens if the shit does hit the fan, well we can all place our heads between our legs and kiss our arses goodbye, to be honest if it kicks off then they say we will have about 45 minutes in which to say goodbye to loved ones, as most of my family are spread around the south east I would not have time so see them, the mobile or cell phone systems would be the first to go, EMP's from the first bomb would kill all mobiles so it would be once again as in world war 2 for those with transceivers i.e. radio enthusiasts to keep comms open and let those of us with radios that still work know whats going on.
Anyway, It's time for me to do some real work, putting lecture together and stuff like that.
