I think Iran and Bashar al-Assad have arrived at the end!
Putin may need Iran and the Assad regime in the middle of the poultry, but the Sunni alliance does not agree to eat, four million Muslims of Russia's 12 million people are risen and 4 percent of the Muslim autonomous and influenced areas.
If Russia leaves Syria, then in less than a month, a Shi'ite could not be found in Syria. Because the war in Syria is the fight of the followers of Ahle Sunna with Shi'a.
