Answer:
All of these is the right answer.
All of the choices in the question show that the Vietnam War had important social and political effects.
b. Politicians were afraid to send American troops overseas. The Vietnam War was a long, expensive, and controversial war that split American society deeply. Because of how unpopular the war was and how hard it was for American troops, many politicians decided to be more careful in the future about getting involved in military conflicts abroad.
c. Television could have a big effect on how people felt about wars. The Vietnam War was the first major conflict that was shown on TV in American living rooms. The graphic and often disturbing images shown on TV had a big effect on how people felt about the war. This experience changed how the media covered future wars and how the public thought about the role of the media in wartime reporting.
d. Less trust in government: The Vietnam War was a very divisive war that made people lose faith in the government and political institutions. Many Americans questioned the motives and skills of their leaders because of how the government handled the war. For example, the government only gave some people certain information and made controversial decisions.
