High-profile opposition to the Vietnam War increasingly turned to mass protests in an effort to shift U.S. public opinion . Riots broke out at the 1968 Democratic National Convention during protests against the war . After news reports of American military abuses , such as the 1968 My Lai Massacre , brought new attention and support to the anti-war movement , some veterans joined Vietnam Veterans Against the War . On 15 October 1969 , the Vietnam Moratorium attracted millions of Americans . The fatal shooting of four students at Kent State University in 1970 led to nationwide university protests . Anti-war protests declined with the final withdrawal of troops after the Paris Peace Accords in 1973
