It's ramping up, it will only take the odd trigger happy individual to start it off, the nuclear power facilities must be a serious concern given the amount of them, look how far it spread and what happened when Chernobyl went pop, and that was only one.
Bring back the cold war, at least that had a stabilising factor on these things, It just needs some big balls in Washington to ramp up a response to tell him once and for all it will not be tolerated, sadly I feel that is lacking, both here and there.
I do feel sorry for the disabled Olympians who may lose their chance after years of hard work..
