Probably what the commanders on the ground advised, and what was the original plan:
one that would have relied on the Iraqi military to help secure and rebuild the country, and had been approved at a White House meeting that Mr. Bush convened just 10 weeks earlier.
When Mr. Bush convened his top national security aides before the March 2003 invasion, he was presented with a clear American plan on what to do with the Iraqi armed forces. American commanders and Jay Garner, the retired lieutenant general who served as the first American administrator in Iraq, planned to use the Iraqi military to help protect the country and as a national reconstruction force.
The plan was outlined in a PowerPoint presentation that
Douglas J. Feith, a senior aide to Defense Secretary
Donald H. Rumsfeld, gave at a National Security Council meeting that Mr. Bush convened on March 12, eight days before the invasion began. Republican Guard units, the forces deemed most loyal to Mr. Hussein, were to be disarmed, detained and dismantled.
But the rest of the army would be retained. Three to five of the divisions would be used to form the “nucleus” of a new Iraqi Army, according to a copy of the PowerPoint slide, which was obtained by The New York Times. Other Iraqi troops would be used as a reconstruction force to rebuild the nation.
