It's always sort of amazing, sitting in Baghdad, to watch visiting dignitaries being received in the Green Zone by politicians who have usually very little support and seldom go outside the Green Zone.

In 2014, everybody kind of knows that the Iraqi army fled when it was attacked by ISIS. But actually, the Kurdish Peshmerga, although they had a better reputation, fled even faster, about a month later, when they were attacked.

Mosul stands rally at a sort of juncture of sectarian and ethnic differences.

Young Shia who have been brought up with nothing, who are pretty anarchic, pretty dangerous. In 2004 when they came close to killing me, and of course they have killed very large numbers of other Iraqis. That's a major source of strength for Muqtada.

Turkey is saying that it wants to preserve Sunni dominance in Mosul. Obviously, there, the Kurds, the Shia, the Iraqi government have their own agendas.

There's a lot of expectation in the Middle East that post-Obama there will be a sort of tougher U.S. line on Assad, there will be more intervention and so forth. But I don't know if that's going to be fulfilled. If there is more intervention, then I think it's going to go the same way as these other interventions that we've seen in Iraq, we've seen, to a degree, in Syria, we've seen in Libya, you know, that they do really badly. They make bad situations worse.

There are some things that could hold it together, notably oil revenues. But at the moment, the much vaunted surge has had a measure of success primarily, to my mind, because Sunni and Shia Iraqis hate and fear each other more these days than they hate and fear the Americans.
