I believe the facts that have brought us to this fateful vote are not in doubt. Saddam Hussein is a tyrant who has tortured and killed his own people, even his own family members, to maintain his iron grip on power. He used chemical weapons on Iraqi Kurds and on Iranians, killing over 20,000 people.
In 1998, Saddam Hussein pressured the United Nations to lift the sanctions by threatening to stop all cooperation with the inspectors. In an attempt to resolve the situation, the U.N., unwisely in my view, agreed to put limits on inspections of designated sovereign sites, including the so-called Presidential palaces--which in reality were huge compounds, well suited to hold weapons labs, stocks, and records which Saddam Hussein was required by U.N. resolution to turn over.
When Saddam blocked the inspection process, the inspectors left. As a result, President Clinton, with the British and others, ordered an intensive 4-day air assault, Operation Desert Fox, on known and suspected weapons of mass destruction sites and other military targets.
In 1991, Saddam Hussein invaded and occupied Kuwait, losing the support of the United States. The first President Bush assembled a global coalition, including many Arab States, and threw Saddam out after 43 days of bombing and hundreds of hours of ground operations.
As a condition for ending the conflict, the United Nations imposed a number of requirements on Iraq, among them disarmament of all weapons of mass destruction, stocks used to make such weapons, and laboratories necessary to do the work. Saddam Hussein agreed and an inspection system was set up to ensure compliance. Though he repeatedly lied, delayed, and obstructed the inspectors' work, the inspectors found and destroyed far more weapons of mass destruction capability than were destroyed in the gulf war, including thousands of chemical weapons, large volumes of chemical and biological stocks, a number of missiles and warheads, a major lab equipped to produce anthrax and other bioweapons, as well as substantial nuclear facilities.
In 1998, the United States also changed its underlying policy toward Iraq from containment to regime change and began to examine options to effect such a change, including support for Iraqi opposition leaders within the country and abroad. In the 4 years since the inspectors, intelligence reports show that 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 terrorists, including al-Qaida members, though there is apparently no evidence of his involvement in the terrible events of September 11, 2001.
