A harsher, but still accurate, description is that Obama strategy boils down to nudging Iraqis and Syrians to decide, on their own, to take the hard but necessary steps to solve this on their own.
Well, in Iraq the local solution will be for the Iraqi Shia to team up with Iran and send the Shia death squads out to slaughter every Sunni in the country to the last man, woman, and child. Something similar would probably end up being the solution in Syria as well.
I’m not terribly averse to that solution, by the way. As long as the victors don’t try to attack us afterwards.
