Question

How did the My Lai Massacre affect public perception of the Vietnam War back home?

Answer 1

During the Mai Lai Massacre US forces killed women an children and when it was broadcast in the US the American people were not accepting of this tragedy.

Answer 2

The My Lai massacre changed public perception of Vietnam drastically. Many people already thought it was an unjust war, and this added to that anti-war sentiment. When many veterans came home they were treated like trash, because everyone back home saw the terrible war crimes committed by the U.S.  Many people called for an end to Vietnam after it.
