You can see Christopher Hitchens talking to Peter Robinson on the programme Uncommon Knowledge, and also read a transcript of their conversation, here. An excerpt (corrected by me from the video clip):
Christopher Hitchens: The welcome that I've seen American and British forces get in parts of Iraq is something I want to start - I want to mention first because there are people who say that that never happened. It is commonly said by, umm, political philosophers like Maureen Dowd say that the - where were the sweets and where were the flowers? Well, I saw it happen with my own eyes and no one's going to tell me that I didn't. I saw it with - months after the invasion, people still lining the roads, especially in the south.(Thanks: HG.)
Peter Robinson: In the south?
Christopher Hitchens: Especially in the south - still lining the roads and waving and the children waving which is always the sign, because if the parents don't want them to, they don't. For miles, it was like going - it was like, this is the nearest I'll get to taking part in the liberation of the country, to ride in with the liberating army. I'll never forget, and I will not allow it not to be said that that did not happen. And in the marshes too - the marsh Arab area of the country which was drained and burned out and poisoned by Saddam Hussein. Again, almost hysterical welcome, and in Kurdistan in the north. So, extraordinary. But remember you said the population hated Saddam Hussein, that's true, really true. But more than anything, they feared him. They were terrified of him. These are people who were not just forced to obey under terrible and believable threat, but made to applaud, made to participate, made to come out and vote, made to come out and demonstrate that they loved him, made to applaud when their relatives were executed. If your kids were going to be shot, you had to attend and you had to applaud, okay. A pornographic regime in other words. Now people who have been through that are humiliated.
[T]he hatred for the regime [in Iran] among the young is a delightful thing to see, as is the friendship towards the United States. And I have a word for it - it's the baby boomerang. You see, the Mullahs threw away so many of their young people in the suicide wave war with Saddam Hussein - which people I think still remember, the throwing away of handfuls of the younger generation. You know, it turned into a pointless war. They had to give Iranian women incentives to make up the deficit.
Peter Robinson: To produce. Right.
Christopher Hitchens: Now there is a baby boom but it's a baby boomerang, because this younger generation despises the Mullahs and the state that they run, wants to live in America, wants - if it can't do that, wants to live an American life. The regime meanwhile is becoming visibly senile. It's not reproducing itself, palpably senile. So even the revolutionary guards are getting a bit long in the tooth.
