The One Certainty About Iraq: Spiraling Costs for Americans: "There are many uncertainties about the progress made by coalition forces and the future prospects for stability and democracy in Iraq, but there is at least one indisputable fact: The Bush administration vastly underestimated the costs of the Iraq war.
Not only in human lives, but in monetary terms as well, the costs of the U.S.-led invasion of Iraq far exceed the administration's initial projection of a $50 billion tab. While the number of American casualties in Iraq has declined this year, the amount of money spent to fight the war and rebuild the country has spiralled upward."
Initial projection: $50 Billion
Latest projection: $1 Trillion
That's 20X more than projected.
And look what we have to show for it!
