Description: 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.

Description: Iranian President Mahmoud Ahmedinejad was elected June 24, 2005, to a four-year term, becoming the first non-cleric president in 24 years. He defeated former president Akbar Hashemi Rafsanjani in a run-off. Prior to his 2005 election to the presidency, Ahmadinejad did not hold an elected office and was a virtual unknown in the international arena. This report covers his background; his victory over the well-known former president Rafsanjani; his remarks about the West, including Israel; and recent visits to Iraq and Latin America.

Description: According to an Administration national security strategy document released on March 16, 2006, the United States "may face no greater challenge from a single country than Iran." The Bush Administration announced May 31, 2006, that it would negotiate with Iran in concert with U.S. allies. If diplomacy and sanctions do not succeed, some advocate military action against Iran's nuclear infrastructure rather than acquiescence to a nuclear-armed Iran. U.S. concerns regarding Iran include Iran's nuclear program, Iran's influence on Iraq by way of providing arms and other material assistance to Shiite Islamist militias, and Iran's human rights practices, which include strict limits on free expression and repression of ethnic and religious minorities.

Description: According to the Administration's "National Security Strategy" document released on March 16, 2006, the United States "may face no greater challenge from a single country than Iran." To date, the Bush Administration has pursued several avenues to attempt to contain the potential threat posed by Iran, including supporting a long-term policy of changing Iran's regime. Iran's nuclear program is not the only major U.S. concern on Iran. Successive administrations have pointed to the threat posed by Iran's policy in the Near East region, particularly material support to groups that use violence to prevent or complicate Israeli-Arab peace. Iran's human rights practices and strict limits on free expression have been consistently criticized by official U.S. and U.N. reports.
