Obama isn't the problem in Iraq. It's Maliki

But it is not clear Maliki wanted that many troops. Indeed, he was conscious of the extreme unpopularity of a continued U.S. presence among his Shia base, and he had no interest in a sizable U.S. contingent along the Arab-Kurd divide, which is what all of our military’s troop options above the 10,000-man threshold assumed. These disputed boundary areas include Kirkuk as well as parts of Nineveh province north of Mosul and portions of Diyala province—precisely where jihadists are making inroads today.
Others claim the administration spent more time negotiating with itself than it did trying to get a deal from the Iraqis. Perhaps. But, in the end, the immunities issue would likely not have been resolved even if the administration had started negotiations earlier and offered more. There was little the administration could have offered or threatened to change their calculations. It was simply too toxic, politically, for Iraqi politicians to accept.
