The United Nations deadline for the withdrawal of Iraqi forces from occupied Kuwait expires, preparing the way for the start of Operation Desert Storm.

The Gulf War was an armed campaign waged by a United States-led coalition of 35 countries against Iraq in response to the Iraqi invasion and annexation of Kuwait.

On 2 August 1990, the Iraqi military invaded the neighbouring State of Kuwait, and had fully occupied the country within two days. Different speculations have been made regarding the true intents behind the invasion, including Iraq's inability to pay Kuwait the more than US$14 billion that it had borrowed to finance its military efforts during the IranIraq War, and Kuwait's surge in petroleum production levels which kept revenues down for Iraq. Throughout much of the 1980s, Kuwait's oil production was above its mandatory OPEC quota, which kept international oil prices down. Iraq interpreted Kuwait's refusal to decrease its oil production as an act of aggression towards the Iraqi economy. The invasion of Kuwait was met with international condemnation, and economic sanctions against Iraq were immediately imposed by the United Nations Security Council in response. British prime minister Margaret Thatcher and American president George H. W. Bush deployed troops and equipment into Saudi Arabia, and urged other countries to send their own forces to the scene. In response to the call, an array of nations joined the U.S.-led coalition, forming the largest military alliance since World War II. The bulk of the coalition's military forces were from the United States, with Saudi Arabia, the United Kingdom, and Egypt as the largest lead-up contributors, in that order. Kuwait and Saudi Arabia paid around US$32 billion of the US$60 billion cost.The initial conflict to expel Iraqi forces from Kuwait began with an aerial and naval bombardment on 17 January 1991, which continued for five weeks. During this period, Iraq began to launch missiles into Israel with the aim of provoking a response by the Israeli military, which the Iraqi leadership expected to prompt the coalition's Muslim states to withdraw and therefore jeopardize the alliance against Iraq. As the Iraqi missile campaign against Israel failed to generate the desired response, Iraq also launched Scud missiles at coalition targets stationed in Saudi Arabia. This was followed by a ground assault by the coalition into Iraqi-occupied Kuwait on 24 February. The offensive was a decisive victory for coalition forces, who liberated Kuwait and promptly began to advance past the IraqKuwait border into Iraqi territory. 100 hours after the beginning of the ground campaign, the coalition ceased its advance and declared a ceasefire. Aerial and ground combat was confined to Iraq, Kuwait, and areas straddling the IraqSaudi Arabia border.

The war marked the introduction of live news broadcasts from the front lines of the battle, principally by the American network CNN. It has also earned the nickname Video Game War after the daily broadcast of images from cameras onboard American bombers during Operation Desert Storm. The Gulf War has gained notoriety for including three of the largest tank battles in American military history.

The United Nations Organization (UNO) or just United Nations (UN) is an intergovernmental organization whose purpose is to maintain international peace and security, develop friendly relations among nations, achieve international cooperation, and be a centre for harmonizing the actions of nations. It is the world's largest and most familiar international organization. The UN is headquartered on international territory in New York City, and has other main offices in Geneva, Nairobi, Vienna, and The Hague (home to the International Court of Justice).

The UN was established after World War II with the aim of preventing future wars, succeeding the rather ineffective League of Nations. On 25 April 1945, 50 governments met in San Francisco for a conference and started drafting the UN Charter, which was adopted on 25 June 1945 and took effect on 24 October 1945, when the UN began operations. Pursuant to the Charter, the organization's objectives include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law. At its founding, the UN had 51 member states; with the addition of South Sudan in 2011, membership is now 193, representing almost all of the world's sovereign states.The organization's mission to preserve world peace was complicated in its early decades by the Cold War between the United States and Soviet Union and their respective allies. Its missions have consisted primarily of unarmed military observers and lightly armed troops with primarily monitoring, reporting and confidence-building roles. UN membership grew significantly following widespread decolonization beginning in the 1960s. Since then, 80 former colonies have gained independence, including 11 trust territories that had been monitored by the Trusteeship Council. By the 1970s, the UN's budget for economic and social development programmes far outstripped its spending on peacekeeping. After the end of the Cold War, the UN shifted and expanded its field operations, undertaking a wide variety of complex tasks.The UN has six principal organs: the General Assembly; the Security Council; the Economic and Social Council (ECOSOC); the Trusteeship Council; the International Court of Justice; and the UN Secretariat. The UN System includes a multitude of specialized agencies, funds and programmes such as the World Bank Group, the World Health Organization, the World Food Programme, UNESCO, and UNICEF. Additionally, non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the UN's work.

The UN's chief administrative officer is the secretary-general, currently Portuguese politician and diplomat António Guterres, who began his first five year-term on 1 January 2017 and was re-elected on 8 June 2021. The organization is financed by assessed and voluntary contributions from its member states.

The UN, its officers, and its agencies have won many Nobel Peace Prizes, though other evaluations of its effectiveness have been mixed. Some commentators believe the organization to be an important force for peace and human development, while others have called it ineffective, biased, or corrupt.
