From the transcript:
President Bush: Saddam Husein will not change and will keep on playing games. The time has come to get rid of him. That's the way it is. For my part, I will try, from now on, to use the most subtle rhetoric possible, while we seel approval of the resolution. If somebody vetoes it [Russia, China and France, alongside the US and UK, have veto power as permanent members of the Security Council], we will go [into Iraq?]. Saddam Hussein is not disarming. We must get him right now. We have shown an incredible degree of patience until now. There are two weeks left. In two weeks' time we will be militarily ready. I believe that we will obtain the second resolution. In the Security Council we have the three Africans [Cameroon, Angola and Guinea], and also the Chileans, the Mexicans. I will speak with all of them, also with Putin, naturally. We will be in Baghdad at the end of March.
The European Tribune has this to say about the story:
El Pais, Spain's largest newspaper, part of a center-left Spanish media Empire (PRISA), has obtained the minutes of a conversation between President Bush and Prime Minister Aznar in February 2003 in Crawford, days before the introduction of the second UN Security Council resolution sponsored by Spain, the UK and the US demanding that Saddam Hussein disarm and which would eventually be withdrawn to avoid an embarrassing defeat.
More from the transcript:
Prime Minister Aznar. I agree, but it would be good to count on the maximum number of people possible. Have a little patience.
President Bush. My patience is exhausted. I don't intend to go beyond mid-March.
Prime Minister Aznar. I am not asking you to have an infinite patience. Simply that you do what you can for everything to fit.
You gotta read this.
