George H.W. Bush presided over the end of the Cold War and the decline of the Soviet Union. He launched the Gulf War in response to Iraq's invasion of Kuwait. Bill Clinton defeated Bush in 1992 and presided over a period of economic growth but was impeached for perjury related to an affair with Monica Lewinsky. The 2000 election between Al Gore and George W. Bush was extremely close and controversial, ultimately being decided by the Supreme Court in Bush's favor.
