The correct answer is A. It divided them
Step-by-step explanation:
The Vietnam War was a conflict between 1955 and 1975 that involved the U.S. as the government decided to military support South Vietnam against North Vietnam that was supported by China and the Soviet Union. Despite the American losses in this war, the whole war had a great impact in the U.S. mainly because the country was divided in those that supported the involvement of the U.S. in a foreign war and those that believed this was immoral and should be stopped; also, many citizens felt the government was not considering their opinion and was manipulating the media to show the war was positive, this decision also divided the support of different political parties. Therefore, the Vietnam war mainly divided American citizens.
