Twelve years ago, Saddam Hussein faced the prospect of being the last casualty in a war he had started and lost. To spare himself, he agreed to disarm of all weapons of mass destruction. For the next 12 years, he systematically violated that agreement. He pursued chemical, biological, and nuclear weapons, even while inspectors were in his country. Nothing to date has restrained him from his pursuit of these weapons, not economic sanctions, not isolation from the civilized world, not even cruise missile strikes on his military facilities.
