August 2, 1990: Iraq, led by Saddam Hussein, invades neighboring Kuwait.
Iraq's invasion of Kuwait is triggered in part because of Iraq's inability to repay more than $20 billion in loans to Kuwait, but also because of other issues related to historical border disputes. By a vote of 14-0, the UN Security Council condemns the invasion and demands unconditional withdrawal of Iraqi troops from Kuwait. On August 6, the UN imposes sanctions on Iraq, ending all trade with the aggressor nation. A U.S.-led coalition forms to forcibly remove Iraq from Kuwait. The Persian Gulf War will cost $8.1 billion and 383 U.S. lives before it ends in March 1991.
