U.S into Iraq

I disagree with Patrick Doherty's article on why Bush went into Iraq. All of the reason that he states are very interesting though. All three reasons are good reasons why the U.S would want to go into Iraq. They would help us with our oil crisis, help Israel, and military. Going into Iraq would definitely benefit these three reasons. But I do not believe that the U.S would go into Iraq for these reasons.

The U.S would not be willing to go behind its citizens backs and lie about why they went into Iraq. They also would not take advantage of such a serious event like 9/11. Doherty seems to believe that 9/11 made our government happy or was possibly planned by the U.S government so that we could go into Iraq. This is ridiculous and 9/11 did not have anything to do with the U.S government.
I believe that they went into Iraq because they had reasonable belief that Iraq had weapons and were a threat to the U.S. They would not be able to just make this up and pretend they think they have weapons.
