One of the greatest dangers we face is that weapons of mass destruction might be passed to terrorists who would not hesitate to use those weapons. Saddam Hussein has longstanding, direct and continuing ties to terrorist networks. Senior members of Iraqi intelligence and al Qaeda have met at least eight times since the early 1990s. Iraq has sent bomb-making and document forgery experts to work with al Qaeda. Iraq has also provided al Qaeda with chemical and biological weapons training. And an al Qaeda operative was sent to Iraq several times in the late 1990s for help in acquiring poisons and gases.
We also know that Iraq is harboring a terrorist network headed by a senior al Qaeda terrorist planner. This network runs a poison and explosive training camp in northeast Iraq, and many of its leaders are known to be in Baghdad.
