As long as it does not involve boots on the ground, I am more than willing to have the US compromise on its interventionist policies by just bombing IS from afar. The only thing to really follow this up with is by changing our policy to promote a multiple state solution. Let the Kurds rule themselves in the north, the shia in the east with baghdad and give the crazies their caliphate in the west, contained on all sides by US supported allies (kurds, turkey, Iraqi government, jordan).

My ideal situation is for the US to use this opportunity to relax tensions with Iran by promoting cooperation with each other against the Sunni extremists that are clearly looking for nothing more than hell on earth.
