I've heard that comment from several analysts commenting on the bush budget. The budget makes several assumptions, the cost of the war being one, that are highly unlikely to come true.

>>Comments like, “it will take ten years before we can leave Iraq”, or “it will be decades before we can rebuild the infrastructure of Iraq”, are not something most Americans want to hear. Yet these are the words coming from the Presidents Staff.

>The real cost to the US of the Iraq war is likely to be between $1 trillion and $2 trillion (£1.1 trillion), up to 10 times more than previously thought, according to a report written by a Nobel prize-winning economist and a Harvard budget expert.
>The study, which expanded on traditional estimates by including such costs as lifetime disability and healthcare for troops injured in the conflict as well as the impact on the American economy, concluded that the US government is continuing to underestimate the cost of the war.
