In March 2003 the United States government announced that "diplomacy has failed" and that it would proceed with a "coalition of the willing" to rid Iraq under Saddam Hussein of weapons of mass destruction the US insisted it possessed. The 2003 invasion of Iraq began a few days later.

Prior to this decision, there had been much diplomacy and debate amongst the members of the United Nations Security Council over how to deal with the situation. This article examines the positions of these states as they changed during 2002-2003.

Prior to 2002, the Security Council had passed 16 resolutions on Iraq. In 2002, the Security Council unanimously passed Resolution 1441.

In 2003, the governments of the US, Britain, and Spain proposed another resolution on Iraq, which they called the "eighteenth resolution" and others called the "second resolution." This proposed resolution was subsequently withdrawn when it became clear that several permanent members of the Council would cast no votes on any new resolution, thereby vetoing it. [1] Had that occurred, it would have become even more difficult for those wishing to invade Iraq to argue that the Council had authorized the subsequent invasion. Regardless of the threatened or likely vetoes, it seems that the coalition at no time was assured any more than four affirmative votes in the Council—the US, Britain, Spain, and Bulgaria—well short of the requirement for nine affirmative votes.[2]

The Iraq War, or the War in Iraq (also referred to as the Occupation of Iraq, the Second Gulf War, or Operation Iraqi Freedom by the United States military), was a conflict that occurred in Iraq from March 20, 2003 to December 15, 2011, though sectarian violence continues since and has caused hundreds of fatalities.

Prior to the war, the governments of the United States and the United Kingdom claimed that Iraq's alleged possession of weapons of mass destruction (WMD) posed a threat to their security and that of their coalition/regional allies. In 2002, the United Nations Security Council passed Resolution 1441 which called for Iraq to completely cooperate with UN weapon inspectors to verify that Iraq was not in possession of WMD and cruise missiles. The United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) found no evidence of WMD, but could not verify the accuracy of Iraq's declarations regarding what weapons it possessed. Lead weapons inspector Hans Blix advised the UN Security Council that while Iraq was cooperating in terms of access, Iraq's declarations with regards to WMD still could not be verified.

Iraq (/ɪˈræk/ or ⁱ/ɪˈrɑːk/; Arabic: العراق‎ al-‘Irāq); officially the Republic of Iraq (Arabic:  جمهورية العراق (help·info) Jumhūriyyat al-‘Irāq), is a country in Western Asia spanning most of the northwestern end of the Zagros mountain range, the eastern part of the Syrian Desert and the northern part of the Arabian Desert.

Iraq borders Syria to the northwest, Turkey to the north, Iran to the east, Jordan to the southwest and Kuwait and Saudi Arabia to the south. Iraq has a narrow section of coastline measuring 58 km (36 mi) on the northern Persian Gulf. The capital city, Baghdad is in the center-east of the country.

Two major rivers, the Tigris and Euphrates, run through the center of Iraq, flowing from northwest to southeast. These provide Iraq with agriculturally capable land and contrast with the steppe and desert landscape that covers most of Western Asia.

Historically, Iraq was the center of the Abbasid Arabic Islamic Empire. Iraq has been known to the west by the Greek toponym 'Mesopotamia' (Land between the rivers) and has been home to continuous successive civilizations since the 6th millennium BC. The region between the Tigris and Euphrates rivers is often referred to as the cradle of civilization and the birthplace of writing, law and the wheel. At different periods in its history, Iraq was the center of the indigenous Akkadian, Sumerian, Assyrian, Babylonian, and Abbasid empires. It was also part of the Achaemenid, Hellenistic, Parthian, Sassanid, Roman, Rashidun, Umayyad, Mongol, Safavid, Afsharid, and Ottoman empires, and under British control as a League of Nations mandate.

The United Nations Security Council (UNSC) is one of the principal organs of the United Nations and is charged with the maintenance of international peace and security. Its powers, outlined in the United Nations Charter, include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action. Its powers are exercised through United Nations Security Council resolutions.

The Security Council held its first session on 17 January 1946 at Church House, Westminster, London. Since its first meeting, the Council, which exists in continuous session, has travelled widely, holding meetings in many cities, such as Paris and Addis Ababa, as well as at its current permanent home at the United Nations Headquarters in New York City.

There are 15 members of the Security Council, consisting of five veto-wielding permanent members—China, France, Russia, the United Kingdom, and the United States—based on the great powers that were the victors of World War II, and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time. This requirement of the United Nations Charter was adopted to address a weakness of the League of Nations since that organization was often unable to respond quickly to a crisis.

Colin Luther Powell ( /ˈkoʊlɨn/; born April 5, 1937) is an American statesman and a retired four-star general in the United States Army. He was the 65th United States Secretary of State, serving under President George W. Bush from 2001 to 2005. He was the first African American to serve in that position. During his military career, Powell also served as National Security Advisor (1987–1989), as Commander of the U.S. Army Forces Command (1989) and as Chairman of the Joint Chiefs of Staff (1989–1993), holding the latter position during the Gulf War. He was the first, and so far the only, African American to serve on the Joint Chiefs of Staff.

Colin Luther Powell was born on April 5, 1937 in Harlem, a neighborhood in the New York City borough of Manhattan, to Jamaican immigrant parents Maud Arial (née McKoy) and Luther Theophilus Powell. He also has Scottish ancestry. Powell was raised in the South Bronx and attended Morris High School, a former public school in the Bronx, from which he graduated in 1954. While at school, he worked at a local baby furniture store where he picked up Yiddish from the shopkeepers and some of the customers. He received his Bachelor of Science degree in geology from the City College of New York in 1958 and was a self-admitted C average student. He was later able to earn a Master of Business Administration degree from the George Washington University in 1971, after his second tour in Vietnam.
