I don't think there can be peace with the jihadis. I really think they want to kill them all if not then drive them back to the gulf states that sponsored them so they can cause trouble there. Russia and Iran are too close to dominating the region now not to keep pushing. The coalition is ununified in its intent whereas the Assad, iraq Russia and Iran Alliance obviously wants to get rid of all military threats to the government.I think they want to win a big fight in Aleppo then dash to the border and cut the supply lines. Then go for peace talks in a magnanimous fashion.
But Assad is struggling for manpower and moralee. They need a break.
