The U.S. handover of sovereignty to Iraq was done quietly Monday morning in Iraq.
I'm sure that much speculation will be made of the rescheduling of the event, but I am sure that there is a very simple explanation...
Paul Bremer wanted to get back to the states in time for Spider-Man 2 on Wednesday. He probably thought everything would work out fine when the movie was scheduled to open on July 2nd; but then they moved it up to June 30th and it forced Bremer to speed things up.
This scenario will be denied by all concerned, but I can understand the reasoning and applaud Bremer's priorities.
