Answer:
The correct answer is C. As a result of the Vietnam War, more Americans began to distrust the U.S. government.
Step-by-step explanation:
The Vietnam War, and in particular the US intervention, was hotly debated as it went on and continues to be the subject of debate. Generally, people who identify themselves as left-wing supporters usually consider that the Vietnam War was a completely unnecessary and illegitimate war.
In turn, conservative debaters have sometimes expressed that the war was necessary to fight communism and compare it, among other things, with the Korean War, which resulted in roughly the same American death toll. It is believed that South Korea's development into a prosperous democracy shows that war can be necessary and have a positive impact on development.
The first anti-war demonstration was held in Washington in 1965, in which some 20,000 people gathered. In Washington in November 1969, around 500,000 people demonstrated against the war. Opinion surveys began to show that a clear majority of the country's population considered the US had to leave Vietnam.
When Nixon invaded Cambodia in 1970 to cut off the FNL's supply lines, it was met by violent protests. A number of universities were occupied by their students who held protest meetings and seminars against the war. The anti-war opinion even penetrated the army. The refusal to serve in Vietnam became more and more common, while protests against the war began to be noticed even among the American soldiers in Vietnam.
Ultimately, the majority of American society turned against the war. They considered it to be an unjustified killing of young Americans, who were sent to die by the government. This vision, added to the defeat, left the government in a very bad position in front of its citizens, who lost all their faith in the politicians of the time.
