I dunno. In the West we took 600 years, and numerous wars and revolutions, to go from the middle ages to the modern world. So why can;t the guys in the Middle East do it in a couple of months?
Probably for the same reason that they were able to rapidly go from sitting around watching the fire for entertainment, to watching TV on their satellite dishes, flying to Mecca in airplanes, talking on cell phones, and setting up websites.
Maybe they can do it becasue they have the advice and guidance of the most successful large-scale experiment in such governance ever? Switzerland has been as successful, but it's on a smaller scale---though it might be a better model for Iraq than the US.
