Iran is materially assisting all major Shiite Muslim political factions in Iraq, most of which have longstanding ideological, political, and religious ties to Tehran, and their armed militias. The Administration notes growing involvement by Tehran in actively directing training, and arming Shiite militiamen linked, to varying degrees, to hardline cleric Moqtada Al Sadr. Some analysis goes so far as to see a virtual "proxy war" between the United States and Iran inside Iraq.

This report outlines Iran's activities and influence in Iraq. Iran is materially assisting major Shiite Muslim political factions in Iraq, most of which have longstanding ideological, political, and religious ties to Tehran, and their armed militias.

This report examines India-Iran relations and U.S. interests. India's growing energy needs and its relatively benign view of Iran's intentions will likely cause policy differences between New Delhi and Washington. India seeks positive ties with Iran and is unlikely to downgrade its relationship with Tehran at the behest of external powers, but it is unlikely that the two will develop a broad and deep strategic alliance. India-Iran relations are also unlikely to derail the further development of close and productive U.S.-India relations on a number of fronts.

This report examines Iran's influence in Iraq post-Saddam. This is in large part because the dominant parties in Iraq have long-standing ideological, political, and religious sectarian ties to Tehran. A key U.S. concern is that Iran, seeking to ensure the political prospects of its proteges, supports Shiite militias that are committing sectarian violence. Since December 2006, the Administration has tried to reverse Iranian influence in Iraq while also engaging Iran diplomatically on Iraq.

This report examines various issues regard Iran and its nuclear program.International Atomic Energy Agency (IAEA) inspections since 2003 have revealed two decades’ worth of undeclared nuclear activities in Iran, including uranium enrichment and plutonium separation efforts. Iran agreed in 2003 to suspend sensitive activities in negotiations with Germany, France, and the UK (EU-3), which broke down in August 2005. On September 24, 2005, the IAEA Board of Governors found Iran to be in noncompliance with its Nuclear Nonproliferation Treaty (NPT) safeguards agreement and reported Iran’s case to the U.N. Security Council in February 2006. The Security Council called upon Iran to resuspend enrichment and reprocessing, reconsider construction of its heavy water reactor, ratify and implement the Additional Protocol, and implement transparency measures. Iran has continued its enrichment activities, failing to meet deadline after deadline. The Security Council passed UNSCR 1696 on July 31, 2006, and on December 23, 2006, the Security Council adopted limited sanctions under UNSCR 1737. The next deadline is February 23, 2007.

This report describes Iran's influence over the post-Saddam government in Iraq. A key concern is that Iran is extending support for related militias in Iraq that are now responsible for much of the sectarian violence in Iraq.

This report describes Iran's known nuclear sites listed in official International Atomic Energy Agency (IAEA) reports and includes a map with the location of the nuclear facilities.

This report discusses India's nonproliferation record and reported transfers to Iran of limited nuclear, chemical, and missile-related materials. Members of Congress have questioned whether India's cooperation with Iran might affect U.S. and other efforts to prevent Iran from developing nuclear weapons.

No firms have been sanctioned under the Iran-Libya Sanctions Act (ILSA), and it has terminated with respect to Libya. In August 2001, the Iran-Libya Sanctions Act (ILSA, P.L. 104-172) was renewed for another five years (P.L. 107-24). No firms have been sanctioned under ILSA, and ILSA has terminated with respect to Libya. In the 109th Congress, H.R. 282 and S. 333 contain provisions that would modify ILSA. This report discusses various issues including the background and passages of the ILSA and its effectiveness.

Report discussing U.S. concerns with Iran, including concerns relating to endorsements given to terrorist organizations by the Iranian government, nuclear weaponry, and human rights practices.

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.

Iran's influence over the post-Saddam government in Iraq is substantial because the predominant parties in that government have long enjoyed Tehran's sponsorship. An emerging concern is that Iran's influence has extended to support for militant groups in Iraq. U.S. officials say that sophisticated explosive devices are entering Iraq from Iran, suggesting that Iran, or factions within Iran, are backing Iraqi factions that use violence to oppose the U.S. presence in Iraq.

The Iran-Libya Sanctions Act (ILSA) was introduced in response to Iran's stepped-up nuclear program and its support to terrorist organizations. No firms have been sanctioned under ILSA, and it has terminated with respect to Libya. Renewed in August 2001 for another five years, ILSA was scheduled to expire in August 2006. This report describes ILSA in detail, as well as related legislation.

This report discusses the political environment in Iraq and its implications on U.S. policy. Much of the debate over U.S. policy toward Iran 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.

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.
