Why were some people in favor of U. S. Military involvement in vietnam and other people against it?

Some people favored the war because they believed the US had an important role to play in the global world. They believed that communism had to be contained at all costs. Others opposed the war because they could not square US involvement in the war with the growing crisis of values and morals about the conduct of the war.

Some people wanted the soldiers to stay so they could end communism all over the world. The would want to push it back so it wouldn't spread.

But a lot more people wanted the soldiers to come back because they didn't trust the government. They would say everything is under control in Vietnam but the poeple would also hear different stories that are negative in Vietnam. The government didn't give the people correct information and the people just wanted the soldiers safe
