Just to set the record straight
In August 2002, our top centrifuge expert said there was no merit to the Bush administration claim that Iraq was acquiring aluminum tubes for uranium enrichment. Earlier, in March 2002, another expert dismissed the Niger yellowcake story.
When your top experts tell you one thing, and you turn around and say the opposite, most people would call that lying.
