Karlo of Swerve Left puts it concisely with his usual unique bite:
Nearly 100,000 Iraqis each month are fleeing to Syria and Jordan. At the same time, there are about 100,000 government contractors operating in Iraq (and this doesn't even include subcontractors). Since Iraq has a population of around 27 million, this means that if we can just "stay the course," the country should be completely empty of Iraqis in about 22 years, after which time it'll be completely populated by Texas oilmen and ex-CIA operatives working for DC subcontracting firms. Shrub might get to build a ranch next to the Euphrates.
