I'm certain that one day we will find that Saddam provided the anthrax for the weeks following the 9-11 attack.
Really? I think Saddam was a menace and we needed to invade since he was threatening his neighbors (Iran included), but his only association with bin Laden is that both grew up in the area we call the Middle East.
These were two different threats - both needed to be taken care of to bring about peace in the Middle East. But Saddam was, previously, a mainly secular figure. One that bin Laden would have opposed.
