NEW YORK — The Nuremberg Principles, a set of guidelines established after World War II to try Nazi Party members, were developed to determine what constitutes a war crime. The principles can also be applied today when considering the conditions that led to the Iraq war and, in the process, to the deaths of hundreds of thousands of people, many of them children, and to the devastation of a country's infrastructure.

In January 2003, a group of American law professors warned President George W. Bush that he and senior officials of his government could be prosecuted for war crimes if their military tactics violated international humanitarian law. The group, led by the New York-based Center for Constitutional Rights, sent similar warnings to British Prime Minister Tony Blair and to Canadian Prime Minister Jean Chretien.

Although Washington is not part of the International Criminal Court (ICC), U.S. officials could be prosecuted in other countries under the Geneva Convention, says Michael Ratner, president of the Center for Constitutional Rights. Ratner likened the situation to the attempt by Spanish magistrate Baltazar Garzon to prosecute former Chilean military dictator Augusto Pinochet when Pinochet was under house arrest in London.
