"This last point is the one that gnaws. Thousands of American lives and hundreds of billions in taxpayer funds have been expended to provide Iraqis the opportunity to live freely. And this despite the facts that (a) the U.S. interest in Iraqi democracy remains tenuous (our interest was the elimination of Saddam’s terror-mongering, weapons-proliferating regime), and (b) Americans were assured, when the nation-building enterprise commenced, that oil-rich Iraq would underwrite our sacrifices on its behalf. Yet, to be blunt, the Iraqis remain ingrates. That stubborn fact complicates everything." - Andy McCarthy, NRO.
Churchill said the same: an "ungrateful volcano". And the Brits were stuck there for decades.
