Which city hosted the Olympic Games that were boycotted by the US in 1980?

The Olympic Games that were boycotted by the United States in 1980 were held in Moscow. This boycott was a response to the Soviet invasion of Afghanistan in December 1979. The U.S. government, along with several other countries, organized the boycott to protest Soviet military actions, believing that participating in the Games would provide legitimacy to the Soviet regime. As a result, many American athletes were unable to compete, which was a significant event in both Olympic history and U.S.-Soviet relations during the Cold War period. The Games in Los Angeles, Seoul, and Beijing occurred in 1984, 1988, and 2008 respectively, and did not involve U.S. boycotts. Therefore, Moscow is identified as the correct answer for the city that hosted the Olympics in 1980 that the U.S. chose to boycott.
