Answer:
A. Many Americans did not support the war.
Step-by-step explanation:
The Vietnam War was a very controversial conflict. It lasted an extremely long time, and once the United States was involved, it was very difficult to take the troops out of the conflict. Moreover, politicians were unwilling to end the war, despite enormous public opposition. Many atrocities were committed during the war, and the United States was responsible for a huge number of them. Therefore, when soldiers returned to the country, they were seen as contributors to an event most people detested. This meant that they were shunned when they returned home.
