Um, you totally missed the point. Saddam was REQUIRED to PROVE he had destroyed these. He did not. Thus, in the absence of proof of destruction, we had to ACT as though they existed. All this means is that we were 100% successful in PROVING that he does not (and will never) have them.
Now, shall we talk abou the Al-Quaeda links---which to me were the far more important reason to take out this regime?
