Vietnam War protesters in Wichita, Kansas, 1967
The draft, a system of conscription that mainly drew from minorities and lower and middle class whites, drove much of the protest after 1965. Conscientious objectors played an active role despite their small numbers. The prevailing sentiment that the draft was unfairly administered inflamed blue-collar American, especially African-American, opposition to the military draft itself.
Opposition to the war arose during a time of unprecedented student activism, which followed the free speech movement and the Civil Rights Movement. The military draft mobilized the baby boomers, who were most at risk, but it grew to include a varied cross-section of Americans. The growing opposition to the Vietnam War was partly attributed to greater access to uncensored information through extensive television coverage on the ground in Vietnam.
Beyond opposition to the draft, anti-war protesters also made moral arguments against U.S. involvement in Vietnam. That moral imperative argument against the war was especially popular among American college students, who were more likely than the general public to accuse the United States of having imperialistic goals in Vietnam and to criticize the war as "immoral." Civilian deaths, which were downplayed or omitted entirely by the Western media, became a subject of protest when photographic evidence of casualties emerged. An infamous photo of General Nguyễn Ngọc Loan shooting an alleged terrorist in handcuffs during the Tet Offensive also provoked public outcry.
Another element of the American opposition to the war was the perception that U.S. intervention in Vietnam, which had been argued as acceptable because of the domino theory and the threat of communism, was not legally justifiable. Some Americans believed that the communist threat was used as a scapegoat to hide imperialistic intentions, and others argued that the American intervention in South Vietnam interfered with the self-determination of the country and felt that the war in Vietnam was a civil war that ought to have determined the fate of the country and that America was wrong to intervene.
Media coverage of the war also shook the faith of citizens at home as new television brought images of wartime conflict to the kitchen table. Newsmen like NBC's Frank McGee stated that the war was all but lost as a "conclusion to be drawn inescapably from the facts." For the first time in American history, the media had the means to broadcast battlefield images. Graphic footage of casualties on the nightly news eliminated any myth of the glory of war. With no clear sign of victory in Vietnam, American military casualties helped stimulate opposition to the war by Americans. In their book Manufacturing Consent, Noam Chomsky and Edward Herman challenge that traditional view of how the media influenced the war and propose that the media instead censored the more brutal images of the fighting and the death of millions of innocent people.
