Answer:
Vietnam veterans did not receive a warm welcome, whereas victory parades were held for veterans from the world wars.
Step-by-step explanation:
Vietnam is very different from the other wars. Public opinion was very negative of the United States' presence in Vietnam. This is for a few reasons. There was no clear objective, it appeared to be unwinnable, and many were against the violence and devastation of war in general. It was perceived as unfair, unnecessary and unjustifiable.
When the soldiers finally came home, they were not heroes to anyone. They were often portrayed as very bad people. This is despite the fact that many of them were sent there against their will due to the draft.
