1. The economic base of the Soviet Union itself is not as good as that of the United States. The predecessor of the Soviet Union is Russia, which itself is the weakest link in the chain of capitalist countries. The failure of World War I led to the intensification of domestic contradictions, which led to the revolution and the establishment of the Soviet Union. After the establishment of the Soviet Union, the country was built on the ruins of Russia, and relying on the economic systems of Lenin and Stalin, it created an economic miracle and became the second industrial power in the world. However, the subsequent World War II severely hit the economy of the Soviet Union, and the main economic zones of the Soviet Union were basically controlled by Germany, resulting in huge losses. Reconstruction was carried out after the war. Therefore, the economic base of the Soviet Union lags far behind that of the United States.

2. It is necessary for the Soviet Union to carry out reforms after the post-war economic recovery, because the Stalin model is no longer suitable for the development of the Soviet Union. However, the reform of the Soviet Union failed one after another. Khrushchev's reform route is correct, but he criticized Stalin's unstable political situation and added helium to cultivate berries. Khrushchev's own decision-making mistakes led to the failure of the reform. Brezhnev's industrial-centered reform route once allowed the Soviet Union to surpass the United States in a short time, but after all, it was to quench thirst by drinking poison, which exhausted the potential of the Soviet Union and eventually led to failure. After Gorbachev came to power, he resumed the correct line economically, but the mistakes in the political line eventually led to the loss of political power.
