I have now watched the Bush speech. It was idealistic, and perhaps a rosy colored glass analysis, but it was informative, in a very general sort of way, and had coherence and brevity. It was better than average for Bush. I have it a "B." I stand by the comments though that the sovereignty thing is cosmetic. It almost perforce has to be. The interim government really has no local legitimacy. It was hand picked by foreigners.
Apparently the UN guy is interviewing tribal chiefs and ethnic groups getting recommendations. So it really isn't hand-picked by foreigners (although I think we can safely assume that Sadr is not on the short list).
