An "Olympic Boycott" occurs when a country or group of countries decides not to participate in the Olympic Games as a form of protest. This action is often taken to express disapproval of political issues, human rights violations, or military actions associated with the host nation. One of the most notable examples is the 1980 Moscow Olympics boycott, where the United States and several other countries refused to compete in response to the Soviet Union's invasion of Afghanistan. In retaliation, the Soviet Union and its allies boycotted the 1984 Los Angeles Olympics.
