My prediction is, it will be Israel, blowing Turkey out of the F water, with any luck. Once the gas flows, Turkshit will interfer with Israel and then she will have to show her whos the boss.
who gives a f*** anyone who starts, the rest will blow us all off this little planet,so if the Turks Israelis Korea, China. just face Mecca bend over and kiss you arse GOODBYE.
I suspect the most likely attack will be by a rogue state who will arrange to smuggle a bomb or bombs in and detonate it in a city probably in either USA and/or Europe, posibly even in China or Japan - no missile tracks and all very deniable.
