The Cold War began after the allied victory in World War II. Until 1952, many of the Communist countries of Eastern Europe had participated in Worker's Olympics or Spartakiads. The Soviet Union emerged from international isolation by eschewing the Spartakiad and participating in the 1952 Summer Olympics in Helsinki; they made their Winter Olympics debut at the Cortina Games. Soviet general secretary Nikita Khrushchev's aim was to use international sports competitions, such as the Olympics, to demonstrate the superiority of communism, strengthen political ties with other communist countries, and project the Soviet Union as a peace-loving nation actively engaged in the world. The Soviets' participation at the Olympics raised the level of competition as they won the most medals and more gold medals than any other nation. Soviet Olympic team was also notorious for skirting the edge of amateur rules. All Soviet athletes held some nominal jobs, but were in fact state-sponsored and trained full-time. According to many experts, that gave the Soviet Union a huge advantage over the United States and other Western countries, whose athletes were students or real amateurs. The Cortina Games were held before the Hungarian Revolution and subsequent Soviet invasion, and the Suez War, which occurred in the autumn of 1956; the Winter Games escaped the boycotts that plagued the Melbourne Olympics, which were celebrated in November and December of that year.
