Analyze the reasons why the United States was involved in the Vietnam War and the impact of the Vietnam War on the United States.

The reasons why the United States launched the Vietnam War;

First, interests: use force against socialist countries and political power to prevent the endless expansion of the Eastern bloc. The national liberation movement led by Ho Chi Minh obviously has this tendency, which is not conducive to the global strategic interests of the United States.

Second: politics: the global strategic struggle between the United States and the Soviet Union.

Third: Goal: This is a concrete step for the United States to implement the global strategic goal, and the United States has shown a strong desire for hegemony in military strikes.

Fourth: Deterrence: If Vietnam is occupied by the United States, it can deter the Soviet Union and China from strategic geography.

Impact on the United States:

Vietnam War is the longest war in American history. In the Vietnam War for more than ten years, the United States spent at least $250 billion. Although the United States has not failed militarily, it shows that the cold war strategy of the United States has made a major mistake. The Vietnam War greatly changed the situation of the Cold War. The United States has changed from a strong side in the cold war to a weak side. In the face of Soviet aggression, the United States cooperated more actively with the people of China. The Vietnam War aggravated the racial and civil rights problems in the United States, which made the country extremely divided and caused great mental trauma to the American people.

The Vietnam War ended the economic prosperity of the United States for 25 years after the war, which caused the American economic situation to plummet. Although the United States has benefited from most wars since the founding of the People's Republic of China, the Vietnam War was the Waterloo of the United States. At the beginning of the war, the defense expenditure increased sharply, and by 1966, the increase rate exceeded 10%. At the same time, the economic growth rate of the United States in the two years from 1965 to 1966 exceeded 6%. However, with the U.S. military operations in Vietnam in trouble, the burden of defense spending is increasing, and the U.S. economy has turned around again, with the economic growth rate dropping from 65,438 to 0,967, down to 2%. From 65438 to 0970, the economic growth of the United States completely stagnated. In fact, the economic crisis broke out from 1969 to 12 in the United States, and the economy recovered from 1982 to 12.
