Here’s an NPR story from February, 2003:
The Bush administration has been decidedly vague about how much a war with Iraq might cost. When pressed, officials have said less than $50 billion. Last year, White House economic adviser Lawrence Lindsey caused a stir when he put the price tag at between 100 and 200 billion at best. The administration dismissed the figure, and Lindsey was soon fired.
Here’s the 2004 WMD report by the CIA:
Advisory groups [Saddam] established generally assumed Saddam already had a preferred position [on issues] and commonly spent time trying to guess what it was and tailor their advice to it. More conscientious members of the Regime sought to work around sycophantic or timid superiors…
The growth of a culture of lying to superiors hurt policymaking…Lack of structural checks and balances allowed false information to affect Iraqi decision making with disastrous effects…
Saddam ignored his economic advisors in the Ministries of Finance and Planning with respect to strategic planning. For example, Saddam entered the Iran-Iraq war heedless of Ministry warnings about the economic consequences. He had no plan or strategy for how the war was to be financed.
