1. Human society must resolutely oppose hegemonism and power politics. After the war, the United States pursued the policy of dominating the world; The Soviet Union pursues hegemonism and chauvinism. The hegemony between the United States and the Soviet Union is the root of the world turmoil, and the historical lesson of the hegemony between the United States and the Soviet Union is painful. The people of the world must always persist in opposing hegemonism and power politics in any form. Hegemonism and power politics are bound to harm others and themselves. The United States and the Soviet Union competed for hegemony, engaged in an arms race, and invested huge military expenditures. 1970, the absolute amount of Soviet military expenditure exceeded that of the United States for the first time. 1977, the absolute military expenditure of the Soviet Union was130 billion US dollars, and that of the United States was1130 billion US dollars in the same year. The huge military expenditure of the United States and the Soviet Union is not conducive to the development of the domestic economy. 1980, the US national debt was as high as 260 billion US dollars; The deterioration of the Soviet Union's economic situation is one of the main reasons for its disintegration. 3. The hegemony between the United States and the Soviet Union puts mankind under the threat of nuclear war. 1962 the Cuban missile crisis almost led to a nuclear war between the United States and the Soviet union. The nuclear weapons of the United States and the Soviet Union can destroy mankind dozens of times. On the other hand, however, the United States and the Soviet Union fought for hegemony in the Cold War, and the bipolar pattern confronted each other for nearly half a century. The main reason for this situation is the great power of high technology, especially under the condition of modern high technology. If there is a nuclear war, there can be no winner, only the warring parties and even the whole mankind will be destroyed. This makes both the United States and the Soviet Union dare not launch a world war or a nuclear war lightly, and can only implement nuclear deterrence. The people of the world, including the people of the United States and the Soviet Union, love peace and oppose war, which also makes it impossible for the United States and the Soviet Union to launch a world war and a nuclear war. Both the United States and the Soviet Union tried to impose their ideology, social system and values on other countries' societies and spread them all over the world. This is a wrong way of thinking and method in dealing with international relations. We must recognize and acknowledge the diversity and unity of the world society, and respect the people of all countries to choose their own development path according to their national conditions. In the early 1990s, the hegemony between the United States and the Soviet Union ended, and the world became multipolar. The emerging multipolar world pattern is an open world strategic pattern, which is a historical progress compared with the pattern of hegemony between the United States and the Soviet Union and is conducive to world peace and development.
