Think Progress has a collection of quotes from the president in the months leading up to the war in Iraq.

Bush: “Of course, I haven’t made up my mind we’re going to war with Iraq.” [10/1/02]

Bush: “You said we’re headed to war in Iraq – I don’t know why you say that. I hope we’re not headed to war in Iraq. I’m the person who gets to decide, not you. I hope this can be done peacefully.” [12/31/02]

Now from the Downing Street memo [7/23/02]:

C reported on his recent talks in Washington. There was a perceptible shift in attitude. Military action was now seen as inevitable. Bush wanted to remove Saddam, through military action, justified by the conjunction of terrorism and WMD. But the intelligence and facts were being fixed around the policy. The NSC had no patience with the UN route, and no enthusiasm for publishing material on the Iraqi regime's record. There was little discussion in Washington of the aftermath after military action.

There was finally a question from the media at the Bush-Blair press conference yesterday on the matter.
