Much of the debate over U.S. policy toward Iran has centered on the nature of the current regime; some believe that Iran, a country of about 70 million people, is a threat to U.S. interests because hardliners in Iran's regime dominate and set a policy direction intended to challenge U.S. influence and allies in the region. President George W. Bush, in his January 29, 2002, State of the Union message, labeled Iran part of an "axis of evil" along with Iraq and North Korea.
