"Those who voted in favor of the resolution authorizing the invasion of Iraq did so despite the fact that it violated international legal conventions to which the U.S. government is legally bound to uphold. The resolution constituted a clear violation of the United Nations Charter which, like other ratified international treaties, should be treated as supreme law according to Article VI of the U.S. Constitution."
"... claims by Senator Hillary Clinton and other leading Democratic supporters of the war that they were unaware of the likely consequences of the invasion are completely false."
"In a speech attacking anti-war activists, President Bush noted how “Many of these critics supported my opponent during the last election, who explained his position to support the resolution in the Congress this way: ‘When I vote to give the President of the United States the authority to use force, if necessary, to disarm Saddam Hussein, it is because I believe that a deadly arsenal of weapons of mass destruction in his hands is a threat, and a grave threat, to our security’.” Indeed, the fact that 2004 Democratic presidential nominee John Kerry voted in favor of the resolution likely cost the Democrats the White House and, should Senator Clinton - who claimed, in justification of her vote to authorize the invasion, that Iraq’s possession of such weapons was “not in doubt” and was “undisputed” - get the nomination, it could also threaten the Democrats’ hopes for victory in 2008."
