Why can Vietnam defeat the United States and achieve reunification? How much aid do you think it received from China and the Soviet Union?

1973, American troops mired in the Vietnam War began to leave Vietnam. This war started at 1965, and lasted for more than 10 years if the time of American indirect intervention was counted. After losing more than 50,000 soldiers' precious lives and spending more than 300 billion yuan on military spending, Americans not only got nothing, but also fell into a quagmire of their own economy and were on the defensive in the global hegemony with the Soviet Union. The Vietnamese can win this war and drive away the Americans. In addition to its own heroic struggle, it has paid huge casualties and sacrifices, and it is also closely related to the assistance of China and the Soviet Union. It can be said that the assistance from China and the Soviet Union enabled Vietnam to deal with the US and South Vietnamese troops for more than ten years. How much material did China and the Soviet Union help Vietnam? The following set of data can give you an intuitive display. China's aid to Vietnam began in the late 1940s. From 65438 to 0947, the local revolutionary armed forces and the masses in Guangxi and Yunnan began to provide assistance to Vietnam within their capacity to resist French colonial rule. 1950 65438+1October 18, New China * * * announced its recognition of the Vietnamese Democratic Republic. At the end of the month, Ho Chi Minh secretly visited China for help. * * * After research, the Central Committee made a major decision to aid Vietnam in an all-round way. Since then, Vietnam has gained a solid rear area in the Anti-Japanese War. According to incomplete statistics, by the end of Vietnam's Anti-French War in 1954, China had provided Vietnam with more than 160000 guns, more than 3600 guns, more than 108000 shells and more than 840000 grenades,123/kloc-. It also provided sufficient logistical support for the Vietnamese army to launch a large-scale campaign. We must know that during this period, our country is carrying out a tough war to resist US aggression and aid Korea, and we also have many difficulties, so we gritted our teeth and took out a lot of materials to help Vietnam. Subsequently, China continued to provide free aid to Viet Nam with unprecedented strength and scale. By the end of 1976, China's aid to Vietnam had been converted into more than 20 billion US dollars, ranging from grain and oil to transportation and weapons. At that time, China's GDP was only 1000 billion dollars. In addition, China has sent 320,000 troops to Vietnam to participate in road construction, communication cable laying and air defense operations, and the related expenses are also borne by China. In addition to military materials, China has also provided free assistance to a large number of other living and production materials, such as grain, seeds, medicines, clothing, gasoline and machinery, as well as a number of projects and foreign exchange in US dollars. In addition, the Vietnamese army's military expenditure in China is all borne by China. While China was helping Vietnam, the Soviet Union was not idle. From 1964 to the end of the Vietnam War, Soviet aid to Vietnam was converted into $25-30 billion, and most of it was military equipment. For example, during the Anti-American War, 80% of Vietnam's heavy weapons were provided by the Soviet Union, including 3 16 fighter planes, 23 Sam -2 air defense missile systems, Sam -3 air defense missile systems of two missile regiments, 687 tanks and more than 70 ships. However, due to the weak foundation, continuous wars and financial difficulties in Vietnam, its revenue and expenditure ratio fell below 50% in 1957. With the escalation of the war, the consumption is increasing. Since 1965, at least 80% of Vietnam's fiscal revenue has been spent on military expenditure. In its income, the proportion of aid from China and the Soviet Union has remained above 60% for a long time, reaching 68.9% in 1968. Until the end of the war, Vietnam could barely solve one-third of its military expenditure. It can be said that this is a proxy war in which neither China nor the Soviet Union participated. Without the support of the two countries, it is impossible for Vietnam to drive away the American troops, let alone destroy South Vietnam and realize national reunification!
