--yes, it is sort of contradictory, but not something that should be too surprising given what has transpired since the 'liberation'. On the other hand, I'm inclined to guess that if the average Iraqi polled were concerned about what would happen if the US pulled out now that they've created a bonafide mess, the key question is just how long will they want the US to have any role in their government as this tragicomedy continues to play itself out.
Re: the cheapshots being taken at Tariq Ali by others in this thread, I'm not sure that Ali would be unable to see these questions in light of their complexity. In fact, if anything, his analysis in Clash of the Fundamentalisms should indicate that he does see quite clearly the complexity of radical politics and occupation.
