McGrath of Harlow- To my mind, here is what it has to do with Iraq.

1.) Saddam Hussein's regime is proven to have little compunction about murdering their own people.

2.) It would follow that he has little compunction about killing other nations' people, as well.

3.) It is established that he seeks weapons (if not already possesses) weapons of mass destruction without a signature.

4.) If he has these weapons, he will either
            a.) use them himself, or
            b.) give them to someone who will use them.

5.) His financial and physical support of terrorism is not deniable. He has allowed Al Qaeda training camps in his country. That provides a verifiable link between his government and the people who attacked us on 9/11 and perpetrate attacks worldwide.
