This report provides an overview of Iran's foreign policy, which has been a subject of numerous congressional hearings and of sanctions and other legislation for many years. The report analyzes Iranian foreign policy as a whole and by region. The regional analysis discusses those countries where Iranian policy is of U.S. concern.

This report discusses the reasons that Iran is considered a threat to U.S. security, including Iran's nuclear program, involvement with terrorist organizations, and involvement with neighboring countries' local governments. It also discusses ways in which the U.S. hopes to modify Iran's behavior with sanctions, and the effectiveness of these sanctions.

The Obama Administration identifies Iran as a major threat to U.S. national security interests. The sense of imminent crisis with Iran which greeted the beginning of 2012 follows three years in which the Obama Administration first offered Iran's leaders consistent and sustained engagement in exchange for limits to its nuclear program but, since 2010, has emphasized pressuring Iran through economic sanctions. This report discusses the effects of economic sanctions against Iran; support to the Iranian democracy movement; and opposition against Iranian human rights violations and Iranian support for Syrian human rights violations.
