On August 2, 1990, Iraq invaded Kuwait, which was strongly opposed by world public opinion. Kuwait is rich in oil, and Iraq's occupation of Kuwait poses a serious threat to the oil supply of Saudi Arabia and the West. The United States and its allies have reacted strongly to this. The "Desert Shield" plan was implemented with the troops of more than 20 countries headed by the US military, and the multinational forces recovered Kuwait by force. The multinational force took off a large number of planes from airports and aircraft carriers in neighboring countries of Iraq, and continuously attacked the Iraqi army. From February 17 to 20, 1991, the multinational force's air force bombed 3,000 sorties per day, killing hundreds of thousands of civilians and tens of thousands of Iraqi soldiers in air strikes; On April 6, 1991, the Iraqi National Assembly accepted UN Resolution 687 after five hours of heated debate. On April 11th, the UN Security Council announced a ceasefire in the Gulf region.
