Iraqi leader Saddam Hussein ordered the invasion and occupation of neighbouring Kuwait in early August 1990. Alarmed by these actions, fellow Arab powers such as Saudi Arabia and Egypt called on the United States and other Western nations to intervene. Hussein defied United Nations Security Council demands to withdraw from Kuwait by mid-January 1991 and the Persian Gulf War began with a massive U.S.-led air offensive known as Operation Desert Storm. After 42 days of relentless attacks by the allied coalition in the air and on the ground, U.S. President George H.W. Bush declared a cease-fire on February 28; by that time, most Iraqi forces in Kuwait had either surrendered or fled. Decisive Battles: Desert Storm examines the lightning-fast decision-making, the political alliances and the machinery that made the Allied victory so decisive.
