A coup for MacMaster, Mattis and their circle. After MacMaster was rebuffed in his attempt fire Flynn's right hand man in the NSC who was supported by Bannon, IMO they decided it was time to get him out of the NSC. Key to this was getting the support of Jared Kushner and so Gen. Dunford invited Jared to join him in Iraq. From Kushner's perspective, the experienced Dunford is a key player in executing his mandate as Trump's front man for Iraq.I'm guessing both men bonded and ensured that in the showdown with MacMaster Bannon would be isolated.
