Iraq war may cost US $2 trillion

From the AP:

War with Iraq could cost the United States anywhere from $99 billion to more than $1.9 trillion over a decade, researchers concluded in a study.

In the worst case, a war could consume the equivalent of an entire Federal budget for one year or close to that, according to the projections. The government spent $2 trillion in the last budget year, which ended Sept. 30.
