Oopsie. Our bad...
Okay, one of our big reasons for invading and conquering Iraq is that they were in league with Al Qaeda, right? Cheney continues to INSIST on the relationship, all evidence to the contrary. Turns out our lead-pipe-cinch evidence was one guy, captured in Pakistan in November '01 and subjected to who-knows-what interrogation techniques. Well, guess what? Now he takes it back. Didn't mean it. Was just saying... oops.
Of course, that he might be lying now is as probably was that he was lying then. Still, wouldn't it be preferable to have more than one possibly-tortured source for something as important as a raison d'etre to invade another country?
