Everything that happens in Iraq affects countries outside.

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.

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

I don't think the whole of Iraq would be under al-Sadr, but I think he would be the predominant force on the Shia side. Quite contrary to his sort of maverick, firebrand image, he's shown a propensity to deal with the other side, to look for compromises, to negotiate. You might have a loose federation [in Iraq].

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

Despite the fact that there's billions of dollars sitting in the Iraqi government reserves, somehow they are incapable of getting it out to the people. There are a very large number of people here who are on the edge of starvation. For those sort of people - a sizable chunk of people - that service makes them regard Muqtada as a sort of god.

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.
