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.

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.

Muqtada leads the only real mass movement in Iraq. It's a mass movement of the Shia, who are 60 percent of the population, and of poor Shia - and most Shia are poor. Otherwise the place is full of sort of self-declared leaders, many of whom spend most of their time outside Iraq.

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.

You know, if you want to meet a lot of Iraqi leaders, the best places are the hotels in Amman or in London. In general the government here is amazingly unpopular.

Muqtada belongs to the most famous religious family in Iraq, which is the al-Sadr family. He's really the third in line. [Muqtada's father] drew his power from the first really important al-Sadr, Muhammad Baqir, who was executed by Saddam in 1980, together with his sister. So it's really a family of martyrs, and that's why Muqtada suddenly emerged from nowhere with the fall of Saddam.

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