* Iraq's noncompliance with the conditions of the 1991 cease fire, including interference with weapons inspectors. Was not enough reason for invasion
* Iraq's alleged weapons of mass destruction, and programs to develop such weapons, posed a "threat to the national security of the United States and international peace and security in the Persian Gulf region." Didn't have WMDs and nuclear programs had been halted
* Iraq's "brutal repression of its civilian population." Other countries are just as bad or worse. Our invasion killed a lot of Iraqis. That's pretty brutal.
* Iraq's "capability and willingness to use weapons of mass destruction against other nations and its own people". We provided him with some of those WMDs he used. We used WMDs against other nations too.
* Iraq's hostility towards the United States as demonstrated by the alleged 1993 assassination attempt of former President George H. W. Bush, and firing on coalition aircraft enforcing the no-fly zones following the 1991 Gulf War. Revenge by Bush Jr is not a reason for war. How many US planes were shot down in the no fly zone?
* Members of al-Qaeda, an organization bearing responsibility for attacks on the United States, its citizens, and interests, including the attacks that occurred on September 11, 2001, are known to be in Iraq. The Al qaeda bases in Iraq were located in the north US protected no fly zone. Al Qaeda hated Saddam as much as GWB did.
* Iraq's "continu[ing] to aid and harbor other international terrorist organizations," including anti-United States terrorist organizations. The US supports dictators all over the world and have supported terrorist groups in South America.
* The efforts by the Congress and the President to fight terrorists, and those who aided or harbored them. Saddam did not aid Al Qaeda
* The authorization by the Constitution and the Congress for the President to fight anti-United States terrorism. Saddam had nothing to do with terror attacks on the US Iran did.
* Citing the Iraq Liberation Act of 1998, the resolution reiterated that it should be the policy of the United States to remove the Saddam Hussein regime and promote a democratic replacement. Creating a act does not give us the right to invade other countries.
