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

Everything that happens in Iraq affects countries outside.

A defeat for ISIS in Iraq will be defeat for ISIS in Syria.

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.

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.

But from the moment George Bush decided to overthrow Saddam, the people who were going to benefit here were the Shia, who are 60 percent of the population. So if you were ever going to have an election, then the Shia would take over.

One of the problems with the media covering this place is that there are stereotypes of news, one of which is "war rages" and the other is "peace dawns." And there isn't much in between. When I talk to foreign journalists, often they are gritting their teeth because they've been asked for a piece about how shops are reopening and restaurants are reopening and so forth - happy pieces. And it just ain't so.
