Could it be an excuse to go all out against ISIS?
That's the OTHER conspiracy theory, False Flag, and must be investigated as well.
The Russians will be more effective in their fight against ISIS than the Americans will be because Putin will not put restrictions on his forces like Obama will put on ours. Let Putin fight ISIS. Putin is no muzzie.
Remember ISIS was proud to say they did it! The fools should have kept quiet and said it was Allahs Will. But No! They took credit—so Russia now has every right to hit back hard. A new chance to test their nukes and turn iSIS Land into a glowing wastland. War will be over when all of ISIS is dead or dying of radiation poisoning. No Islamic nation will dare to oppose Russia after that demonstration.
