Iraq invades Kuwait, eventually leading to the Gulf War.

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.

The Iraqi military invaded the neighbouring State of Kuwait on 2 August 1990 and 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 U.S. 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 U.S. 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 Iraqi invasion of Kuwait was an operation conducted by Iraq on 2 August 1990, whereby it invaded the neighboring State of Kuwait, consequently resulting in a seven-month-long Iraqi military occupation of the country. The invasion and Iraq's subsequent refusal to withdraw from Kuwait by a deadline mandated by the United Nations led to a direct military intervention by a United Nations-authorized coalition of forces led by the United States. These events came to be known as the first Gulf War, eventually resulting in the forced expulsion of Iraqi troops from Kuwait and the Iraqis setting 600 Kuwaiti oil wells on fire during their retreat (see scorched earth strategy).

A variety of speculations have been made regarding the true intents behind the Iraqi move, including Iraq's inability to pay Kuwait more than US$14 billion that it had borrowed from Kuwait to finance the Iran–Iraq 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 the oil prices down. Iraq interpreted Kuwait's refusal to decrease its oil production as an act of aggression. In early 1990, Iraq accused Kuwait of stealing Iraqi petroleum through cross-border slant drilling, although some Iraqi sources indicated that Saddam Hussein's decision to attack Kuwait was already made a few months before the actual invasion. The invasion started on 2 August 1990, and within two days, most of the Kuwaiti military was either overrun by the Iraqi Republican Guard or retreated to neighboring Saudi Arabia and Bahrain. Immediately following the invasion, Iraq set up a puppet government known as the "Republic of Kuwait" to rule over Kuwait, eventually annexing it outright, when Saddam Hussein announced a few days later that it was the 19th province of Iraq.
