If Russia cleans up ISIS quickly the world will know 0dunga was FAKING HIS ASSAULT ON ISIS. How embarrassing, but then again THAT is what 0dunga is in office for!
While that may happen eventually, I don’t think Russia gives a damn about ISIS right now. They’re focused on the immediate strategic goal: keep Assad in power. That means defeating the Free Syrian Army or whatever the hell our “moderate Islam allies” are called.
