Iran was heavily involved in Iraq following the 2003 invasion that toppled Saddam Hussein from power. [1] Iran often used Shia militias within Iraq to disrupt United States operations during the Iraq War, [2] while also directly participating in the insurgency that followed the invasion. [3] [4] Iran funded the Mahdi Army (a group led by Muqtada al-Sadr), as well as Kata'ib Hezbollah, Asa'ib Ahl al-Haq, and the Promised Day Brigade.
During a meeting with British Foreign Secretary Jack Straw on 25 September 2001, Iranian president Muhammad Khatami said "Iran fully understands the feelings of the Americans about the terrorist attacks in New York and Washington on September 11", and that Iranians instead felt differently and had expressed their sympathetic feelings with bereaved Americans. [5] The attacks were condemned by both the President and the Supreme Leader of Iran. [6] [7] The military forces of the United States of America and the Islamic Republic of Iran cooperated with each other to overthrow the Taliban regime which had conflicts with the government of Iran. [8] [9] Iran's Quds Force helped US forces and Afghan rebels in 2001 uprising in Herat. [10]
Months later, in his 2002 State of the Union Address, US President George W. Bush described Iran as being part of an "axis of evil" alongside Iraq and North Korea. Both reformists and conservatives in Iran responded negatively to this characterization, with Masoumeh Ebtekar calling it a "strategic mistake" by the Bush administration. [11] Daniel Heradstveit and G. Matthew Bonham argued that the speech caused a reversal in friendly US–Iranian relations that had developed after the Cold War; the Iranian opposition figures they interviewed saw it as a "betrayal", and widely agreed that it was "a godsend to the conservatives", who favoured a more hostile and militant approach towards the United States. [9]
Several claims have been made that the US has violated Iranian territorial sovereignty through the use of drones since 2003. [12] [13]
In September 1980, Iraq under Saddam Hussein launched an invasion of Iran in an unsuccessful attempt to annex oil-rich Iranian territory, [14] [15] : 261 marking the beginning of a war that would last until 1988. [16] The Iran–Iraq War is regarded as being a major trigger for rising sectarianism in the region, as it was viewed by many as a clash between Sunni Muslims (Ba'athist Iraq and other Arab States) [17] [18] [19] and the Shia revolutionaries that had taken power in Iran. [20]
In a declassified 1991 report, the CIA estimated that Iran had suffered more than 50,000 casualties from Iraq's use of several chemical weapons, [21] though modern estimates have reached more than 100,000, as the long-term effects continued to cause casualties; [22] [23] they also show that the United States was providing reconnaissance intelligence to Iraq around 1987–88, which was then used to launch chemical weapon attacks on Iranian troops, and that the CIA fully knew that chemical weapons would be deployed and sarin and cyclosarin attacks followed. [24] According to Iraqi documents, assistance in developing chemical weapons was obtained from firms in many countries, including the United States. [25]
In January 2002, one year before the U.S.-led invasion of Iraq, bilateral relations between Iran and Iraq improved significantly when an Iranian delegation, led by Amir Hussein Zamani, visited Iraq for final negotiations to resolve the conflict through talks on issues of prisoners of war and those who went missing in action during the Iran–Iraq War. [26]
In the aftermath of the 2003 invasion of Iraq, Iran supported Shi'ite insurgent groups dubbed the Special Groups in Iraq, which were made up by the Mahdi army, Kata'ib Hezbollah, Asa'ib Ahl al-Haq, and the Promised Day Brigade. The U.S. used the Iraqi government to fight these insurgents as a result. [27] [28] [29] [30] A 2008 report by the Combating Terrorism Center at West Point based on reports from the interrogations of dozens of captured Shia fighters described an Iranian-run network smuggling Shia fighters into Iran where they received training and weapons before returning to Iraq. [31] [32]
According to two unnamed US officials, the Pentagon is examining the possibility that the Karbala provincial headquarters raid was supported by Iranians. In a speech on 31 January 2007, Iraqi Prime Minister Nouri al-Maliki stated that Iran was supporting attacks against Coalition forces in Iraq, [33] and some Iraqis suspect that the raid may have been perpetrated by the Quds Force in retaliation for the detention of five Iranian officials by US forces in the northern Iraqi city of Irbil on 11 January. [34] [35]
In 2007, tensions increased greatly between Iran and Iraqi Kurdistan due to the latter's giving sanctuary to the militant Kurdish secessionist group Party for a Free Life in Kurdistan (PEJAK). According to reports, Iran had been shelling PEJAK positions in Iraqi Kurdistan since 16 August. These tensions further increased with an alleged border incursion on 23 August by Iranian troops who attacked several Kurdish villages killing an unknown number of civilians and militants. [36]
An estimated 150 Iranian intelligence officers, plus members of Iran's Islamic Revolutionary Guard Corps, are believed to be active inside Iraq at any given time. For more than a year, U.S. troops have detained and recorded fingerprints, photographs, and DNA samples from dozens of suspected Iranian agents in a catch and release program designed to intimidate the Iranian leadership. [37]
Coalition forces also began to target alleged Iranian Quds Force operatives in Iraq, either arresting or killing suspected members. The Bush administration and coalition leaders began to publicly state that Iran was supplying weapons, particularly EFP devices, to Iraqi insurgents and militias although to date have failed to provide any proof for these allegations. Further sanctions on Iranian organizations were also announced by the Bush administration in the autumn of 2007. On 21 November 2007, Lieutenant General James Dubik, who is in charge of training Iraqi security forces, praised Iran for its "contribution to the reduction of violence" in Iraq by upholding its pledge to stop the flow of weapons, explosives, and training of extremists in Iraq. [38]
Iraq is a country in Western Asia that largely corresponds with the territory of ancient Mesopotamia. The history of Mesopotamia extends from the Lower Paleolithic period until the establishment of the Caliphate in the late 7th century AD, after which the region came to be known as Iraq. Encompassed within Iraqi territory is the ancient land of Sumer, which came into being between 6000 and 5000 BC during the Neolithic Ubaid period of Mesopotamian history, and is widely considered the oldest civilization in recorded history. It is also the historic center of the Akkadian, Neo-Sumerian, Babylonian, Neo-Assyrian, and Neo-Babylonian empires, a succession of local ruling dynasties that reigned over Mesopotamia and various other regions of the Ancient Near East during the Bronze and Iron Ages.
The Iran–Iraq War was an armed conflict between Iran and Iraq that lasted from September 1980 to August 1988. Active hostilities began with the Iraqi invasion of Iran and lasted for eight years, until the acceptance of United Nations Security Council Resolution 598 by both sides. Iraq's primary rationale for the attack against Iran cited the need to prevent Ruhollah Khomeini—who had spearheaded the Iranian Revolution in 1979—from exporting the new Iranian ideology to Iraq. There were also fears among the Iraqi leadership of Saddam Hussein that Iran, a theocratic state with a population predominantly composed of Shia Muslims, would exploit sectarian tensions in Iraq by rallying Iraq's Shia majority against the Baʽathist government, which was officially secular and dominated by Sunni Muslims. Iraq also wished to replace Iran as the power player in the Persian Gulf, which was not seen as an achievable objective prior to the Islamic Revolution because of Pahlavi Iran's economic and military superiority as well as its close relationships with the United States and Israel.
The Islamic Supreme Council of Iraq is a Shia Islamist political party in Iraq. It was established in Iran in 1982 by Mohammed Baqir al-Hakim and changed its name to the current Islamic Supreme Council of Iraq in 2007. Its political support comes from Iraq's Shia Muslim community.
Izzat Ibrahim al-Douri was an Iraqi politician and army field marshal. He served as Vice Chairman of the Iraqi Revolutionary Command Council until the 2003 U.S. invasion of Iraq and was regarded as the closest advisor and deputy under President Saddam Hussein. He led the Iraqi insurgent group Naqshbandi Army.
The following is a timeline of major events during the Iraq War, following the 2003 invasion of Iraq.
The Mahdi Army was an Iraqi Shia militia created by Muqtada al-Sadr in June 2003 and disbanded in 2008.
An Iraqi insurgency began shortly after the 2003 American invasion deposed longtime leader Saddam Hussein. It is considered to have lasted until the end of the Iraq War and U.S. withdrawal in 2011. It was followed by a renewed insurgency.
The Quds Force is one of five branches of Iran's Islamic Revolutionary Guard Corps (IRGC) specializing in unconventional warfare and military intelligence operations. U.S. Army's Iraq War General Stanley McChrystal describes the Quds Force as an organization analogous to a combination of the CIA and the Joint Special Operations Command (JSOC) in the United States. Responsible for extraterritorial operations, the Quds Force supports non-state actors in many countries, including Hezbollah, Hamas, Palestinian Islamic Jihad, Yemeni Houthis, and Shia militias in Iraq, Syria, and Afghanistan. According to Michael Wigginton et al., the Al-Quds Force is "a classic example of state-sponsored terrorism."
The Iraq War was a protracted armed conflict in Iraq from 2003 to 2011. It began with the invasion of Iraq by the United States-led coalition that overthrew the Ba'athist government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the coalition forces and the post-invasion Iraqi government. US troops were officially withdrawn in 2011. The United States became re-involved in 2014 at the head of a new coalition, and the insurgency and many dimensions of the armed conflict are ongoing. The invasion occurred as part of the George W. Bush administration's war on terror following the September 11 attacks.
The 1991 Iraqi uprisings were ethnic and religious uprisings against Saddam Hussein's regime in Iraq that were led by Shi'ites and Kurds. The uprisings lasted from March to April 1991 after a ceasefire following the end of the Gulf War. The mostly uncoordinated insurgency was fueled by the perception that Iraqi President Saddam Hussein had become vulnerable to regime change. This perception of weakness was largely the result of the outcome of the Iran–Iraq War and the Gulf War, both of which occurred within a single decade and devastated the population and economy of Iraq.
The term militia in contemporary Iraq refers to armed groups that fight on behalf of or as part of the Iraqi government, the Mahdi Army and Badr Organization being two of the biggest. Many predate the overthrow of Saddam Hussein, but some have emerged since, such as the Facilities Protection Service. The U.S. invasion of Iraq in 2003 undermined the internal order in the country and brought about, among other things, the establishment of several pro-Iranian militias affiliated with the IRGC's Quds Force. The militias were set up with the purpose of driving the U.S. forces out of Iraq and establishing Iranian involvement in the country. Prominent among the militias are Asa'ib Ahl al-Haq, Kata'ib Hezbollah and Harakat al-Nujaba.
The Karbala provincial headquarters raid was a special operation carried out on January 20, 2007, by The Asa'ib Ahl al-Haq, on the U.S. contingent of the Joint Security Station located within the Iraqi Police headquarters. The assault, which left five U.S. soldiers dead and three wounded, has been called the "boldest and most sophisticated attack in four years of warfare" and is furthermore notable for being one of the few instances when any sort of militants or insurgents have actually managed to capture U.S. soldiers since the Vietnam War.
Since the Iranian Revolution in 1979, the Islamic Republic of Iran has been embroiled in tense relations with the U.S. and its allies. Following the overthrow of the American-backed Shah and a hostage crisis, both countries severed relations. Since then, both countries have been involved in numerous direct confrontations, diplomatic incidents, and proxy wars throughout the Middle East, which has caused the tense nature of the relationship between the two to be called an 'international crisis'. Both countries have often accused each other of breaking international law on several occasions. The U.S. has often accused Iran of sponsoring terrorism and of illegally maintaining a nuclear program, as well as using strong rhetoric against Israel, of which Iran has questioned its legitimacy and its right to exist while supporting Hamas, an antizionist group in the Gaza Strip. Meanwhile, Iran has often accused the U.S. of human rights violations and of meddling in their affairs, especially within the Iranian Democracy Movement.
Special Groups (SGs) is a designation given by the United States military to the cell-based Shi'a paramilitary organizations operating within Iraq, backed by Iran. According to the United States these groups are funded, trained, and armed by the Iranian Quds Force, part of the Islamic Revolutionary Guard Corps (IRGC). According to the United States Department of Defense, 603 American troops in total were confirmed to have been killed by IRGC-backed Shia militias during the Iraq War.
Kata'ib Hezbollah —or the Hezbollah Brigades—is a radical Iraqi Shiite paramilitary group which used to be part of the Popular Mobilization Forces, staffing the 45th, 46th, and 47th Brigades. During the Iraq War (2003–11), the group fought against Coalition forces. It has been active in the War in Iraq (2013–2017) and the Syrian civil war (2011–present). The group was commanded by Abu Mahdi al-Muhandis until he was killed in a US drone attack in 2020. Thereafter, he was replaced by Abdul Aziz al-Muhammadawi, as the new leader of the Popular Mobilization Forces (PMF). KH seeks to establish an Iran-aligned government in Iraq, expel American forces from the country, and advance the regional and international interests of Iran in Iraq and the region. The group is responsible for killing hundreds of U.S. soldiers and takes a central part in carrying out attacks against U.S. targets in Iraq and acts as part of the Axis of Resistance. Kata'ib Hezbollah is directly subordinate to Iranian Islamic Revolutionary Guard Corps's (IRGC) Quds Force and operates under its instructions and guidance.
The Iranian intervention in Iraq has its roots in the post-2003 invasion of Iraq by the United States and allies when the infrastructure of the Iraqi armed forces, as well as intelligence, were disbanded in a process called "de-Ba'athification" which allowed militias with close ties to Tehran to join the newly reconstituted army.
The Second Battle of Tikrit was a battle in which Iraqi Security Forces recaptured the city of Tikrit from the Islamic State of Iraq and the Levant (ISIL). Iraqi forces consisted of the Iraqi Army and the Popular Mobilization Forces, receiving assistance from Iran's Quds Force officers on the ground, and air support from the American, British, and French air forces.
The Popular Mobilization Forces, also known as the People's Mobilization Committee (PMC) and the Popular Mobilization Units (PMU), is an Iraqi state-sponsored umbrella organization composed of approximately 67 different armed factions, with around 230,000 fighters that are mostly Shia Muslim groups, but also include Sunni Muslim, Christian, and Yazidi groups. The Popular Mobilization Units as a group was formed in 2014 and have fought in nearly every major battle against ISIL. Many of its main militias, in particular the Shias, trace their origins to the "Special Groups", Iranian-sponsored shiite groups which previously fought an insurgency against the United States and the Coalition forces, as well as a sectarian conflict against Ba'athist and sunni jihadi insurgents. It has been called the new Iraqi Republican Guard after it was fully reorganized in early 2018 by its then–Commander in Chief Haider al-Abadi, Prime Minister of Iraq from 2014 to 2018, who issued "regulations to adapt the situation of the Popular Mobilization fighters".
Jamal Ja'far Muhammad Ali Al Ibrahim, known by the kunyaAbu Mahdi al-Muhandis was an Iranian-Iraqi commander of the Popular Mobilization Forces (PMF). At the time of his death, he was deputy chief of the PMF and regarded as one of Iraq’s most powerful men.
The Iraqi conflict refers to a near-continuous series of events that began with the 2003 invasion of Iraq and deposition of Iraqi president Saddam Hussein.
