The Russians don't give Fck who rules Syria as long as they have a say and their man tows the line. If this does not sound familiar, you have missed the war. Neither does Iran as long as the Ruler is Shiite and follows their brand of Islam.
Get real...
ALL involved want to see the war stop as long as they dominate when it does stop. They want a situation favorable to their own interests. What you and others miss is thinking this equates to some sort of compassion for the civilians in this entire area. Just like your OPost in the other thread crowing about the Chinese, who have stayed out as they really don't have a whole lot of interest at this point.
The Russians will save the day... Sure thing. If they can get people to the table and satisfied with their position something might be done about ISIS which the Russians have basically ignored.
