The official word on Iraq by Bush

Thanks to Daily Kos for the link.
Emphasis mine. Otherwise, words from the President, directly from the Whitehouse. The U.S. attacked Iraq without provocation, and no one, not even the President thinks that Iraq was responsible for 9/11.
Press Conference by the President

THE PRESIDENT: I square it because, imagine a world in which you had Saddam Hussein who had the capacity to make a weapon of mass destruction, who was paying suiciders to kill innocent life, who would — who had relations with Zarqawi. Imagine what the world would be like with him in power. The idea is to try to help change the Middle East.
Now, look, part of the reason we went into Iraq was — the main reason we went into Iraq at the time was we thought he had weapons of mass destruction. It turns out he didn’t, but he had the capacity to make weapons of mass destruction. But I also talked about the human suffering in Iraq, and I also talked the need to advance a freedom agenda. And so my question — my answer to your question is, is that, imagine a world in which Saddam Hussein was there, stirring up even more trouble in a part of the world that had so much resentment and so much hatred that people came and killed 3,000 of our citizens.
You know, I’ve heard this theory about everything was just fine until we arrived, and kind of “we’re going to stir up the hornet’s nest” theory. It just doesn’t hold water, as far as I’m concerned. The terrorists attacked us and killed 3,000 of our citizens before we started the freedom agenda in the Middle East.
Q What did Iraq have to do with that?
THE PRESIDENT: What did Iraq have to do with what?
Q The attack on the World Trade Center?
THE PRESIDENT: Nothing, except for it’s part of — and nobody has ever suggested in this administration that Saddam Hussein ordered the attack. Iraq was a — the lesson of September the 11th is, take threats before they fully materialize, Ken. Nobody has ever suggested that the attacks of September the 11th were ordered by Iraq. I have suggested, however, that resentment and the lack of hope create the breeding grounds for terrorists who are willing to use suiciders to kill to achieve an objective. I have made that case.
