You're thesis makes no sense. Why would Saddam hire Islamic fundamentalists (who hate him) to attack the U.S.?
Saddam wants to survive. His goal is to get those sanctions lifted and get things back to the "good ol' days".
Why would he risk an ill-advised attack on America that ensures swift destruction for all culprits, including himself?
Saddam may be evil, but he's no fool.
I think that's debatable, actually. This guy has made some serious miscalculations in the past; we cannot be confident that he will behave rationally. That's one of the main reasons he has to be eliminated.
