Either that or it was pay back for numerous attempts on Assad’s life. The Russians knew that ISIL was the real bad guys all along. Now ISIL has taken a lot of the military hardware they took from Iraq, and have driven it back into Syria. So yes, fairly soon Syria will become even more unstable then it is, and that will bring in Russians by the thousands.
This is the beginning of Irans consolidation of Iraq into the Caliphate,
And Obama handed it to them on a silver platter. What’s worse is they do not see the hammer and the anvil. Iran will push ISIS further and further north towards Syria. Syria will start driving them south.
Phase one will be to wipe out ISIS and this is where Russia will help their Syrian ally. Also keep in mind Russia builds Irans nuke plants. Phase two will be a push by Turkey south and they will start attacking the Kurds. With both Syria and Iran on the borders, the hammer will start coming down.
With no one to back the Kurds and siince Obama already said piss off to the Iraqis, and with Russia providing weapons and support, the Kurds will be wiped out. Now include Lebanon in the Caliphate and that means the only thing between a soon to be nuclear Iran and Israel is Jordan.
This won’t end well.
