The time to shut up is now! We, and all the world's superpowers are getting into a 2000 year+ RELIGIOUS WAR. If we, and all of the other powers stay, this will be the beginning of WW3. Listening to the Republican Candidates practically insures WW3.
Ok, Russia is pissed at Turkey, Russia does a little strike on Turkey, Turkey strikes at Russia, Iran Strikes at Turkey, we strike at Iran, and all of a sudden France uses a Nuke on IS. Not to be outdone, Russia strikes at Turkey with a small Nuke, say 10 megaton, Iran has two nukes from Russia and launches these at Jewish religion and we use clean nukes on Iran.
Russia is determined to stop the U.S. and we then have 6,000 Nukes in the air, killing 2 BILLION people, polluting earth with radiation, and providing we are the superpower.
Who knows, 2000 years from now we may kill again in the name of Religion.
OR
Shut the Hell up and attempt with abandon to settle things down.
