But the U.S. has to be careful. If our strategy depends on Sunnis doing the fighting to clear Mosul and Ramadi - and, as near as I can tell, that is the strategy - then you have to be careful that Sunnis don't perceive the U.S. to be operating arm in arm with Iran or with Iranian-backed Shiite militias that Abadi - Prime Minister Abadi is using in Iraq, so that, in effect, we're fronting for Iran.

It's very hard to understand just what our strategy is in Syria, frankly, and on Iraq that this is Iraq's war, that the role of the United States is to help Iraq, to arm, train, support, provide air support, but this has to be Iraq's war.

Retrospective analysis is not a useful guide to current problems.
