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. This book explores Iran's political history, regime structure, ballistic missile program, economic conditions, stability, and presidential elections.
