that Iraqi President Saddam Hussein was now "trying, through his illicit procurement network, to acquire the equipment he needs to be able to enrich uranium -- specifically, aluminum tubes." Secretary of State Colin Powell spoke on Fox News Sunday, saying "And as we saw in reporting just this morning, he is still trying to acquire, for example, some of the specialized aluminum tubing one needs to develop centrifuges that would give you an enrichment capability." National Security Advisor Condoleezza Rice said on CNN's Late Edition with Wolf Blitzer that the tubes "are only really suited for nuclear weapons programs, centrifuge programs" and "we don't want the smoking gun to be a mushroom cloud."

Most intelligence specialists assessed this to be the intended use, but some believed that these tubes were probably intended for use as casings for tactical rockets." In July 2003, following the March invasion of Iraq, the CIA said in a report to Congress that "We are not yet at the point where we can draw comprehensive or final conclusions about the extent of Iraq's prewar WMD program." It repeated this language in its report in January 2004.
