What with Obama specifically omitting Christians when voicing concern for the Yazidis and also saying, “we are not going to be the Kurd’s Air Force” he is giving IS a green light elsewhere. I think that Iran has no desire for anything beyond a holding action against IS in the south and east Shiite and oil areas. I’d be getting out of Bagdad just about now.
Iran taking the whole thing means easier support for/from their buddies in Turkey, don’t forget. They have a desire for the whole area; the Islamic Republic is not a reasonable entity.
