I was thinking about that just now, and many have posted that they thought it was nukes, or other proscribed weapons. How about this other possibility:
Since we've essentially proven that Iraq had something to do with 9/11 by helping OBL, and now we're seeing that Chiraq is doing all he can to help Saddam, maybe the bottom line is that Chiraq was the one who gave the orders for or provided major assistance for 9/11 - along with Germany. After all, Atta and Co were in Hamburg for a long time.
Chiraq, in his arogance and lust for power - especially his desire to take the US down a notch or two - provides ample motive for him to be behind 9/11. The proximity of the Hamburg location plus the meetings between Atta and the Iraqis could very well have been expedited by the French as well.
