Then it should be easy for you to locate Bush establishing such a link. Pointing out an admission counter to interest isn't invalid.
If you think it is a logical fallacy you better dig out a copy of Copi's Logic and read the section on argumentum ad verecundiam, as you evidently think any appeal to authority is a fallacy. Bush is certainly an authority on his own interest and qualified to be quoted.
I have given facts ad all you have is a vague assertion that maybe Bush hasnt had the political fortitude to make those same assertions. BFD, they still stand as reality. You havent even given a quote of Bush, so there is nothing for me to dispute wrt Bush.
fact: Saddam sponsored, aided, funded, harbored and trained terrorists from many different groups, including Al Qaeda.
