This report outlines the background and original passage of the ILSA (Iran-Libya Sanctions Act), its key provisions which excluded Libya from the act, its implementation and effectiveness and the proposed modifications and extensions to the ILSA.

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. For further information and analysis of Iran's nuclear programs, see CRS Report RS21592, Iran's Nuclear Program: Recent Developments, by Sharon Squassoni; and CRS Report RL32048 Iran: U.S. Concerns and Policy Responses, by Kenneth Katzman.

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 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.

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.

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 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.

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.

International Atomic Energy Agency (IAEA) inspections since 2003 have revealed almost two decades' worth of undeclared nuclear activities in Iran, including uranium enrichment and plutonium separation efforts. The Security Council called upon Iran to take steps requested of it by the IAEA Board in February -- reinstate its suspension of enrichment and reprocessing, reconsider construction of its heavy water reactor, ratify and implement the Additional Protocol, and implement transparency measures. Iran has continued enrichment activities and failed to meet the Security Council's request.

The Bush Administration has pursued several avenues to attempt to contain or end the potential threat posed by Iran, at times pursuing limited engagement directly or through allies, and at other times leaning toward pursuing efforts to change Iran’s regime. Over the past two years, the Administration has focused primarily on blunting Iran’s nuclear program by backing diplomatic efforts by European nations and Russia to negotiate permanent curbs on it. International concerns on nuclear issues and other strategic issues have been heightened by the accession of Mahmoud Ahmadinejad, a hardliner, as president. He advocates a return to many of the original principles of the Islamic revolution as set down by the late Ayatollah Ruhollah Khomeini. Some advocate military action against Iran’s nuclear infrastructure, but others believe that continued diplomacy, combined with offers of economic rewards or threats of international sanctions is the only viable option. Still, others believe that only an outright replacement of Iran’s regime would diminish the threat posed by Iran to U.S. interests.

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.

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 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.” That perception might have intensified in the context of Iran ally Lebanese Hizballah’s military challenge to Israel in July 2006. 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. However, the near-term Administration drive to prevent any Iranian nuclear weapons breakthrough has brought diplomatic and economic strategies to the forefront of U.S. policy.
