(CNN) – In his upcoming memoir, former Secretary of Defense Donald Rumsfeld describes a Bush administration marred by chaos and disorder during the months leading up to the Iraq War – the prime reason, he says, why the postwar transition was so poorly planned.
"There were far too many hands on the steering wheel, which, in my view, was a formula for running the truck into a ditch," writes Rumsfeld in Known and Unknown, which is set to hit bookstores next week. Advanced excerpts were first obtained by the New York Times and Washington Post.
Rumsfeld writes a key point of disagreement revolved around how quickly to hand power to a new Iraqi government. The Pentagon, he writes, favored a quick transition to power while the more-wary State Department said a slower process would better ensure new and legitimate leaders emerged in the fragile country.
Ultimately, Rumsfeld blames former President Bush for not clearly resolving the disagreement and clearly charting a post-war plan before hostilities commenced, instead deferring to his point man on Iraq reconstruction, L. Paul Bremer.
Bush "did not always receive, and may not have insisted on, a timely consideration of his options before he made a decision, nor did he always receive effective implementation of the decisions he made,” writes Rumsfeld.
Bremer, suggests Rumsfeld, pursued a muddled reconstruction plan that more closely resembled that which was advocated by the State Department. At the same time, Rumsfeld gripes Bremer did not keep the Pentagon informed of his decision making.
"Those key differences were never clearly or firmly resolved in the NSC," Rumsfeld writes. "Only the President could do so."
Rumsfeld also directs blame toward himself, according to the released excerpts, writing that he wished he had resigned in 2004 when the Abu Ghraib prison photos suggested Americans were torturing detainees. Bush, writes Rumsfeld, rejected two separate resignation letters dated five days apart in the after math of the scandal.
"Looking back, I see there are things the administration could have done differently and better with respect to wartime detention," says Rumsfeld.
A spokesman for President Bush had no comment. CNN has also reached out to Bremer and is awaiting a response.
