You'd never know this crisis was going on at all if you read the US press; the only place I'm seeing anything about it is here on FR, where people are gleaning little scraps from various sources.
As for Blair, I doubt that he talked GWB into anything with regard to Iraq. But whether he did or not, I honestly don't think the US would indulge in such idealistic plans again: no more attempting to conquer a country without any civilian damage, no more attempting to bring the blessings of democracy before the conquered citizens have a nice long period under martial law until they settle down, etc. And no more foggy ideas about Islam as a "religion of peace."
