In the Cold War, the United States and the Soviet Union competed after the Second World War, controlling the military affairs of Europe through NATO and the Warsaw Pact. The first supported liberal democracy and capitalism, while the second favored communism and an economy planned by the government. Both supported several dictatorships and participated in proxy wars. Between 1950 and 1953, U.S. troops fought Chinese communist forces in the Korean War. From the break with the USSR and the start of the Cold War until 1957, McCarthyism also called the Second Red Dread, developed within the United States. The State unleashed a wave of political mistreatment and a campaign of prejudice against Communists, which some authors point out as of a totalitarian state. Hundreds of people were arrested, including celebrities, and between 10,000 and 12,000 people lost their jobs. The abuse ended when the courts declared it unconstitutional.
