Wow. This thing speaks for itself. I can add nothing.

No way for Bush to justify unprovoked war with Iraq
"...back in 1990, Iraq's brutal invasion of its fellow Arab nation ensured that Hussein, not the United States, would bear the moral burden of starting a major war. At the time, the United States also had the strong endorsement of the United Nations, pledges of financial assistance from Japan, Saudi Arabia and others, the offer of bases in Turkey and Saudi Arabia and the support of most of the Arab world, including Yasser Arafat. Twelve years ago today, in fact, Egypt announced it would contribute troops to the effort. Today none of that is true. We have instead an administration trying to sell a pre-emptive war on the basis of weapons that Iraq might have, and whether it might give those weapons to terrorists. There is no evidence that Hussein has even contemplated such a step, and considerable history to the contrary. For at least 20 years, Hussein has had access to chemical weapons and has never once let them out of his control.Furthermore, endorsing the concept of pre-emptive war as a legitimate use of power is extremely risky. It is essentially the rationale imperial Japan used to justify its attack on Pearl Harbor more than 60 years ago."
