By late December  some 200,000 members of the U.S. armed forces were en route to staging areas surrounding Iraq.... Declaring that it was impossible to make predictions about a war that might not occur, the Administration refused to discuss plans for the war's aftermath--or its potential cost. In December the President fired Lawrence Lindsey, his chief economic adviser, after Lindsey offered a guess that the total cost might be $100 billion to $200 billion.
On March 27 , eight days into combat, members of the House Appropriations Committee asked Paul Wolfowitz for a figure. He told them that whatever it was, Iraq's oil supplies would keep it low. "There's a lot of money to pay for this," he said. "It doesn't have to be U.S. taxpayer money. We are dealing with a country that can really finance its own reconstruction, and relatively soon."On April 23 Andrew Natsios, [director] of USAID, told an incredulous Ted Koppel, on Nightline, that the total cost to America of reconstructing Iraq would be $1.7 billion. Koppel shot back, "I mean, when you talk about one-point-seven, you're not suggesting that the rebuilding of Iraq is gonna be done for one-point-seven billion dollars?"Natsios was clear: "Well, in terms of the American taxpayers' contribution, I do; this is it for the U.S. The rest of the rebuilding of Iraq will be done by other countries who have already made pledges ... But the American part of this will be one-point-seven billion dollars. We have no plans for any further-on funding for this."
In the end, what did it really cost? Matthew Duss and Peter Juul of CAP have a summary. Among the elements: the direct cost of the war was about $800 billion, compared with the "shocking" estimate by Lawrence Lindsay of $100 billion to $200 billion. The cost of veterans' care and disabilities would be another $400 billion to $700 billion. And Iraqi reconstruction, which Natsios and Wolfowitz had said would be essentially self-financing? This is how it compared not simply with Natsios's "one-point-seven billion dollars" but also, in inflation-adjusted dollars, with outlays for the Marshall Plan and other recovery efforts after World War II.
