“In the four years since the inspectors left, intelligence reports show the Saddam Hussein has worked to rebuild his chemical and biological weapons stock, his missile delivery capability and his nuclear program. He has also given aid, comfort and sanctuary to terrorist, including al-Qaida members . It is clear, however, that if left unchecked. Saddam Hussein will continue to increase his capacity to wage biological and chemical warfare, and will keep trying to develop nuclear weapons.” -Sen. Hillary Clinton D-NY Oct 10, 2002
