Vietnam War was a long, costly, divisive dispute that overwhelmed the communist government of northern Vietnam and the southern Vietnam and its key ally United States. The dispute was strengthened by the ongoing cold war between the United States and the Soviet Union.
In the Vietnam War, more than three million people (including more than 58000 Americans) were killed and more than half of the dead were Vietnam civilians. Even after President Richard Nixon ordered the US troops to withdraw in 1973, the Americans were divided violently against the United States war.
The Communist Party took control of the South in 1975 and ended the war Vietnam the following year. The Vietnam war has intensified United States ethnicity and citizenship issues, and has severely split the nation, causing an enormous injury to Americans.
The Vietnam War ended a 25-year economic boom in the postwar United States, and the economic situation of the United States rapidly changed. Vietnam War was the longest war in American history, and United States spent at least 250 billion dollars. United States has not failed militarily, but it has shown a mistake in the Cold War strategy. Vietnam War has drastically changed the Cold War situation.
United States has become a weak public during the Cold War. From the 1960s to the end of the 1970s, the United States economy entered a period of long-term stagnation. Some scholars believe that military production during the Vietnam war has stimulated domestic economic development. In the early days of the Vietnam War, war facilitated economic prosperity. In the second semester, the adverse effects of the war gradually emerged due to the worsening United States economic environment.
