Iranian Retreat From Iraq

Maybe:

Petraeus Tells Duncan Hunter That Iranian Arms Shipments Increased, But Quds Force Has Departed

That from National Review's the campaign spot:

There was a drop-off for a couple of weeks, but we do not see a sign of that abating. The [Iranian] Quds Force have been pulled out of the country, as well as Lebanese Hezbollah trainers who were used in assistance [by Iran].

H/T Hot Air.
