The inspectors-Clouseaux like "Dr" Hans (Where the hell did they get that name) Blix may not find any smoking gun. Is it possible that the greater amounts of WMD were moved across borders to other countries?
Remember, terrorism and their organizations are not ruled or deterred by geographic borders. I think we saw that on Sept. 11. It could be well possible that terrorist cells will plan for a swift and purposed counter-attack on Anglo-American soil (aka "The West", the "Great Satan", the "Infidels", ad nauseum) right after any U.S. or U.N. coalition attack on Iraq. That could be the reason why minimus observed people becoming "faint out of fear" over this looming war in particular. That's just my theory, of course.
