We can hope. But Russia's objective is propping up Syria, its client state. They will only attack ISIS when it is threatening Syria.
But any bomb dropped on ISIS' heads is a good bomb.
Follow the emerging war strategy
Putin and the Syrians need to clean out the islamists of all stripes and names from the major cities towns bases and loc’s in In western Syria, and cut off their supply routes from Turkey
then they can go into the center which is the ISIS “ caliphate”
They are making some sorties into ISIS territory to target command centers and ammo and equipment sites before the rats all make a run for Mosul or Turkey
Today it looks more certain that Iraq is going to be cooperating with Russia so cutting off escape of ISIS from Syria back into Iraq
Hopefully this will bring the Russians Kurds and Iraqis all together in cleaning out central Iraq and cleaning out Mosul
Just watch for provocation by muslim brotherhood operative Erdogan to skunk up the works
