World War I Main articles: Mesopotamian campaign, Damascus Protocol, McMahon-Hussein Correspondence, and Sykes–Picot Agreement During World War I the Ottomans were driven from much of the area by the United Kingdom during the dissolution of the Ottoman Empire. The British lost 92,000 soldiers in the Mesopotamian campaign. Ottoman losses are unknown but the British captured a total of 45,000 prisoners of war. By the end of 1918 the British had deployed 410,000 men in the area, though only 112,000 were combat troops. During World War I the British and French divided Western Asia in the Sykes-Picot Agreement. Treaty of Lausanne, led to the advent of modern Western Asia and Republic of Turkey. The League of Nations granted France mandates over Syria and Lebanon and granted the United Kingdom mandates over Iraq and Palestine (which then consisted of two autonomous regions: Palestine and Transjordan). Parts of the Ottoman Empire on the Arabian Peninsula became parts of what are today Saudi Arabia and Yemen.

Invasion and civil war Main article: 2003 invasion of Iraq Further information: Iraq War An Iraqi Army unit prepares to board a Task Force Baghdad UH-60 Blackhawk helicopter for a counterinsurgency mission in Baghdad. Iraqi troops going in to action in the year 2007.On March 20, 2003, a United States-organized coalition invaded Iraq, with the stated reason that Iraq had failed to abandon its nuclear and chemical weapons development program in violation of U.N. Resolution 687. The United States asserted that because Iraq was in material breach of Resolution 687, the armed forces authorization of Resolution 678 was revived. The United States further justified the invasion by claiming that Iraq had or was developing weapons of mass destruction and stating a desire to remove an oppressive dictator from power and bring democracy to Iraq. In his State of the Union Address on January 29, 2002, President George W. Bush declared that Iraq was a member of the "Axis of Evil", and that, like North Korea and Iran, Iraq's attempt to acquire weapons of mass destruction posed a serious threat to U.S. national security. These claims were based on documents that were provided to him by the CIA and the government of the United Kingdom.[50] Bush added, "Iraq continues to flaunt its hostilities toward America and to support terror. The Iraqi regime has plotted to develop anthrax, and nerve gas, and nuclear weapons for over a decade... This is a regime that agreed to international inspections — then kicked out inspectors. This is a regime that has something to hide from the civilized world... By seeking weapons of mass destruction, these regimes [Iran, Iraq and North Korea] pose a grave and growing danger. They could provide these arms to terrorists, giving them the means to match their hatred."[51] However, according to a comprehensive U.S. government report, no weapons of mass destruction have been found.[52] There are accounts of Polish troops obtaining antiquated warheads, dating from the 1980s, two of which contained trace amounts of the nerve gas cyclosarin, but U.S. military tests found that the rounds were so deteriorated that they would "have limited to no impact if used by insurgents against coalition forces." [53][54][55][56][57][58] Iraq was also home to 1.8 tons of low-enriched uranium, miscellaneous other nuclear materials, and chemical weapons paraphernalia; the nuclear material was under the supervision of the IAEA until the beginning of the war.

Gulf War Main articles: Invasion of Kuwait and Gulf War In 1990, faced with economic disaster following the end of the Iran–Iraq War, Kuwait started overproduction of oil which kept oil revenues down for Iraq. Saddam Hussein decleared that the invasion was a response for that. The Iraqi government also claimed that Kuwait was illegally slant drilling its oil wells into Iraqi territory, a practice which it demanded be stopped; Kuwait rejected the notion that it was slant drilling, and Iraq followed this in August 1990 with the invasion of Kuwait. Upon successfully occupying Kuwait, Hussein declared that Kuwait had ceased to exist and it was to be part of Iraq, against heavy objections from many countries and the United Nations. The UN agreed to pass economic sanctions against Iraq and demanded its immediate withdrawal from Kuwait (see United Nations sanctions against Iraq). Iraq refused and the UN Security Council in 1991 unanimously voted for military action against Iraq. The United Nations Security Council, under Chapter VII of the United Nations Charter, adopted Resolution 678, authorizing U.N. member states to use "all necessary means" to "restore international peace and security in the area." The United States, which had enormous vested interests in the oil supplies of the Persian Gulf region, led an international coalition into Kuwait and Iraq. The mixture of civilian and military vehicles on the Highway of Death. Estimates of Iraqi military deaths range from 8,000 to 100,000.[38]The coalition forces entered the war with more advanced weaponry than that of Iraq, though Iraq's military was the fourth-largest army in the world [39], it had already been 8 years in war with Iran. Despite being a large military force, the Iraqi army was no match for the advanced weaponry of the coalition forces and the air superiority that the coalition forces provided. The coalition forces proceeded with a bombing campaign targeting military including an occupied public shelter in Baghdad.[40][41][42] Iraq responded to the invasion by launching SCUD missile attacks against Israel and Saudi Arabia. Hussein hoped that by attacking Israel, the Israeli military would be drawn into the war, which he believed would rally anti-Israeli sentiment in neighboring Arab countries and cause those countries to support Iraq. However, Hussein's gamble failed, as Israel reluctantly accepted a U.S. demand to remain out of the conflict to avoid inflaming tensions. The Iraqi armed forces were quickly destroyed, and Hussein eventually accepted the inevitable and ordered a withdrawal of Iraqi forces from Kuwait. Before the forces were withdrawn, however, Hussein ordered them to sabotage Kuwait's oil wells, which resulted in hundreds of wells being set ablaze, causing an economic and ecological disaster in Kuwait. After the decisive military defeat, the agreement to a ceasefire on February 28, and political maneuvering, the UN Security Council continued to press its demands that Hussein accept previous UN Security Council Resolutions, as stated in UNSCR 686. By April, UNSCR 687 recognized Kuwait's sovereignty had been reinstated, and established the United Nations Special Commission on Iraq (UNSCOM). Two days later, UNSCR 688 added that Iraq must cease violent repression of ethnic and religious minorities. The aftermath of the war saw the Iraqi military, especially its air force, destroyed. In return for peace, Iraq was forced to dismantle all chemical and biological weapons it possessed, and end any attempt to create or purchase nuclear weapons, to be assured by the allowing UN weapons inspectors to evaluate the dismantlement of such weapons. Finally, Iraq would face sanctions if it disobeyed any of the demands. Shortly after the war ended in 1991, Shia Muslim and Kurdish Iraqis engaged in protests against Hussein's regime, resulting in an intifada. Hussein responded with violent repression against Shia Muslims, and the protests came to an end.[43] It is estimated that as many as 100,000 people were killed.[44] The US, UK, France and Turkey claiming authority under UNSCR 688, established the Iraqi no-fly zones to protect Kurdish and Shiite populations from attacks by the Hussein regime's aircraft. [edit] Disarmament crisis Main article: Iraq disarmament crisis While Iraq had agreed to UNSCR 687, the Iraqi government sometimes worked with inspectors, but ultimately failed to comply with disarmament terms, and as a result, economic sanctions against Iraq continued. After the war, Iraq was accused of breaking its obligations throughout the 1990s, including the discovery in 1993 of a plan to assassinate former President George H. W. Bush, and the withdrawal of Richard Butler's UNSCOM weapon inspectors in 1998 after the Iraqi government claimed some inspectors were spies for the U.S. Central Intelligence Agency.[45] On multiple occasions throughout the disarmament crisis, the UN passed further resolutions (see United Nations Resolutions concerning Iraq) compelling Iraq to comply with the terms of the ceasefire resolutions. Some contended studies estimate more than 500,000 Iraqi children died as a result of the sanctions.[46][47] With humanitarian and economic concerns in mind, UNSCR 706 and UNSCR 712 allowed Iraq to sell oil in exchange for humanitarian aid. This was later turned into the Oil-for-Food Programme by UNSCR 986. Over the years, U.S. land forces were deployed to the Iraq border, and U.S. bombings were carried out to try to pressure Hussein to comply with UN resolutions. As a result of these repeated violations, US Secretary of State Madeline Albright, US Secretary of Defense William Cohen, and US National Security Advisor Sandy Berger held an international town hall meeting to discuss possible war with Iraq, which seemed to have little public support. In October 1998, U.S. President Bill Clinton signed the Iraq Liberation Act, calling for "regime change" in Iraq, and initiated Operation Desert Fox. Following Operation Desert Fox, and end to partial cooperation from Iraq prompted UNSCR 1284, disbanding UNSCOM and replacing it with United Nations Monitoring, Verification and Inspection Commission (UNMOVIC). The George W. Bush administration made a number of allegations against Iraq, including that Iraq was acquiring uranium from Niger and that Iraq had secret weapons laboratories in trailers and isolated facilities throughout Iraq;[citation needed] none of these allegations have proven true. Saddam Hussein, under pressure from the U.S. and the U.N., finally agreed to allow weapons inspectors to return to Iraq in 2002, but by that time the Bush administration had already begun pushing for war. In June 2002, Operation Southern Watch transitioned to Operation Southern Focus, bombing sites around Iraq. The first CIA team entered Iraq on July 10, 2002. This team was composed of elite CIA Special Activities Division and the U.S. Military's elite Joint Special Operations Command (JSOC) operators. Together, they prepared the battle space of the entire country for conventional U.S. Military forces. Their efforts also organized the Kurdish Peshmerga to become the northern front of the invasion and eventually defeat Ansar Al-Islam in Northern Iraq before the invasion and Saddam's forces in the north. The battle led to the killing of a substantial number of militants and the uncovering of what was claimed to be a chemical weapons facility at Sargat.[48][49] In October 2002, the U.S. Congress passed the Joint Resolution to Authorize the Use of United States Armed Forces Against Iraq, and in November the UN Security Council passes UNSCR 1441.
