We didn't used to have the traditions of law that counted all persons equally - but we grew, and we've changed. The United States understands that the existence of human rights helps secure the peace, deter aggression, promote the rule of law, combat and crime and corruption, stengthen democracies, and prevent humanitarian crises. The United States is a common law country. We derive our legal system from the common law of England and even today common law principles remain applicable where there are no binding statutory provisions. The US supreme court decides on a case by case basis. Thus our highest law in the land, is a case law.
