There is no indication that Iraq shipped any weapons of mass destruction to Syria before or during the U.S.-led invasion, the CIA concluded this week. The theory that Iraqs weapons had been moved to Syria arose after the war, when troops failed to find the weapons of mass destruction that the Bush administration had insisted Iraq possessed. But now that theory has been debunked. Charles Duelfer, head of the CIA group charged with finding WMDs, said this week that he was officially ending his 18-month investigation, having turned up nothing but leftovers from the first Gulf War. He did, however, warn that Iraq had dozens of highly trained weapons scientists who could pose a threat if they sought jobs with hostile foreign governments, terrorists, or insurgents.
