Hmmm.... Somehow it doesn't wash with me... I fully believe that if Iraq actually had the weapons, they would have used them. They would not have given them away or moved them out of the country, they would have used them.
And this part just does not seem right at all.... By january, the CIA would have jumped on a convoy moving out of the country... But the article says:
"U.S. intelligence first identified a stream of tractor-trailer trucks moving from Iraq to Syria to Lebaon in January 2003. The significance of this sighting did not register on the CIA at the time"
