Actually, the Iraq War was a nation building folly by Comrade Bush. All nation building is a fool's game. If Iraqis want freedom, they are equipped to get it themselves. Legitimate governments exist only with the consent of the governed.
Other nation building follies that the U.S. needs to stay out of /should have stayed out of: The Balkans, Darfur, Somalia, Haiti, have I left any out? Lots of leftists like to think they can tell good nation building from bad nation building, I'm trying to head off that nonsense.
