Iran is home to approximately 70.5 million people who are ethnically, religiously, and linguistically diverse. This report discusses these minorities, their treatment under the Islamic regime, and the reactions of international rights groups.

This report looks at the background of Iran's nuclear policy.

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.

The Kurdish-inhabited region of northern Iraq is relatively peaceful and prospering economically, but the Iraqi Kurds' political autonomy and political strength in post- Saddam Iraq is causing friction with Arab leaders in Iraq, Turkey, and Iran.

This report discusses the debate over U.S. policy toward Iran, much of which has centered on the nature of the current regime. Some experts believe that Iran, a country of almost 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 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.
