If it hadn't been for 9-11, Bush never would have had the cajones to go after Saddam. But given the incentive I provided, he looked desperately for a reason and finally found one: Those dastardly weapons of mass destruction.
And what as the final outcome? No WMD's, United States foreign policy is in tatters, and Bush's credibility is non-existent. So yeah, I feel pretty good about how things turned out.
