It's entirely possible Saddam was bluffing and thought an empty threat of WMD's would carry the day. Not much of a poker player.
Saddam is not this much of a gambler.........something isn't right.
Fool the CIA....ok.......but fooling MOSSAD....MI5 and MI6....and Every Intelligence agency in the world for 10 plus years.........nope I don't buy it.
