This is just like the Japanese statement of a couple of weeks ago that Japan had supposedly lost or misplaced some plutonium. You can't take these statements at face value. The Japanese statement was directed at North Korea, and it was a reminder to North Korea that the Japanese not only have plutonium, they have so much plutonium that they may have accounting errors bigger than North Korea's entire stockpile.
With Iraq, it's the same story. They're reminding the world what they have, just in case somebody might have forgotten.
