... What about the war crime known as a "war of aggression"? That's a type of war where one nation initiates an unprovoked attack on another nation. A war of aggression was declared a war crime at Nuremberg. Did the principles that were set forth a Nuremberg apply only to Germany, or were they universal? I think most people would respond that the Nuremberg principles are universal ... It is an undisputed fact that Iraq never attacked the United States or even threatened to do so. It is also undisputed that the president failed to secure the congressional declaration of war against Iraq that the Constitution mandates.
