You may think it is a little chickensh_t for me to bring it up,

but this may be one more reason that Bush rushed us into this war. Specifically, he was possibly starting to realize that his intelligence was faulty and wanted to start the war before more intelligence was disproven.
I feel that it has been pretty well shown that the administration had Iraq in its sights long before 9/11. The 9/11 attack gave them the perfect excuse. Lets look at the players:
For the rush to war:Bush - He had motive to avenge his father and for making up for his father's mistake in not taking out Hussein when he had the chance.
Cheney - He was an architect of outsourcing military support and certainly wanted to see how well it worked. He also had close ties to Halliburton, one of the obvious contractors.
Rumsfeld - He was the inventor of the smaller faster army and wanted to show how well his ideas work.
Rice - I'm sure she saw the Iraqi, American and Enron flag, flapping in the breeze together in a free and profitable Iraq.
Perle - He's the "father" of this war and, along with the other neoconservatives, has been pushing to attack Iraq for more than a decade. Part of his motivation is to protect Israel as he stated in a strategic plan he developed for the Israeli Prime Minister.
Wolfowitz - Another neoconservative.
Feith - Yet another neoconservative.
Against the rush to war:Powell - The only one who had been to war.
