Our original estimate of the cost of the Iraq war was too conservative: in reality the cost for the US will be much higher
by Joseph Stiglitz and Linda Bilmes
President Bush has tried to give the impression that the $3 trillion dollar estimate of the total cost of the war that we provide in our new book may be exaggerated.
We believe that it is in fact conservative. Even the president would have to admit that the $50 to $60 billion estimate given by the administration before the war was wildly off the mark; there is little reason to have confidence in their arithmetic. They admit to a cost so far of $600 billion.
Our numbers differ from theirs for three reasons: first, we are estimating the total cost of the war, under alternative conservative scenarios, derived from the defence department and congressional budget office. We are not looking at McCain’s 100-year scenario - we assume that we are there, in diminished strength, only through to 2017. But neither are we looking at a scenario that sees our troops pulled out within six months. With operational spending going on at $12 billion a month, and with every year costing more than the last, it is easy to come to a total operational cost that is double the $600 billon already spent.
