When the Vietnam War started only a small percentage of the American population opposed the war. Those who initially objected to the involvement in Vietnam fell into three broad categories: people with left-wing political opinions who wanted an NLF victory; pacifists who opposed all wars; and liberals who believed that the best way of stopping the spread of communism was by encouraging democratic, rather than authoritarian governments.
The first march to Washington against the war took place in December, 1964. Only 25,000 people took part but it was still the largest anti-war demonstration in American history.
As the war continued, more and more Americans turned against it. People were particularly upset by the use of chemical weapons such as napalm and agent orange. In 1967, a group of distinguished academics under the leadership of Bertrand Russell, set up the International War Crimes Tribunal. After interviewing many witnesses, they came to the conclusion that the United States was guilty of using weapons against the Vietnamese that were prohibited by international law. The United States armed forces were also found guilty of torturing captured prisoners and innocent civilians. The Tribunal, and other critics of the war, claimed that the US behaviour in Vietnam was comparable to the atrocities committed by the Nazis in Europe during the Second World War.
In November, 1965, Norman Morrison, a Quaker from Baltimore, followed the example of the Buddhist monk, Thich Quang Due, and publically burnt himself to death. In the weeks that were to follow, two other pacifists, Roger La Porte and Alice Herz, also immolated themselves in protest against the war.
The decision to introduce conscription for the war increased the level of protest, especially amongst young men. To keep the support of the articulate and influential members of the middle class, students were not called up. However, students throughout America still protested at what they considered was an attack on people's right to decide for themselves whether they wanted to fight for their country.
In 1965, David Miller publically burnt his draft card (call-up notice) and was sentenced to two and a half years in prison. His actions inspired others and throughout America, Anti-Vietnam War groups organised meetings where large groups of young men burnt their draft cards.
Between 1963 and 1973, 9,118 men were prosecuted for refusing to be drafted into the army. The most famous of these was Muhammad Ali, the world heavyweight boxing champion.
Muhammad Ali was one of the many distinguished black figures who protested against the war. There were several reasons why blacks and other ethnic minorities felt so strongly about Vietnam. One reason involved the expense of the war. By 1968, the Vietnam War was costing 66 million dollars a day. As a result. President Lyndon B. Johnson increased income taxes and cut back on his programme to deal with poverty. The blacks, who suffered from poverty more than most other groups in America, were understandably upset by this decision. Martin Luther King, the Civil Rights leader, argued: "that America would never invest the necessary funds or energies in rehabilitation of its poor as long as Vietnam continued to draw men and skills and money like some demonic, destructive suction tube."
Other Civil Rights leaders pointed out that because of the draft deferment enjoyed by college students, it was the poor who were more likely to be sent to Vietnam. What is more, as Eldridge Cleaver, a Civil Rights activist pointed out, in many southern states of America, blacks were being denied the right to vote in elections. Therefore, blacks were fighting in Vietnam "for something they don't have for themselves." As another black leader put it: "If a black man is going to fight anywhere, he ought to be fighting in Mississippi" and other parts of America.
This advice was taken and in the late 1960s, several cities in the United States suffered violent riots in black ghettos. Anti-Vietnam War leaders began to claim that if the government did not withdraw from the war they might need the troops to stop a revolution taking place in America.
Demonstrations against the war steadily increased in size during the late 1960s. In New York, over a million people took part in one demonstration. The public opinion polls showed that a narrow majority of the people still supported US involvement in Vietnam. However, the polls also indicated that much of this support came from middle class families whose own sons were not at risk.
President Lyndon B. Johnson knew that if the war continued, he would eventually be forced to start drafting college students. When that happened he would have great difficulty obtaining majority support for the war.
The most dramatic opposition to the war came from the soldiers themselves. Between 1960 and 1973, 503,926 members of the US armed forces deserted. Many soldiers began to question the morality of the war once they began fighting in Vietnam. One soldier, Keith Franklin, wrote a letter that was only to be opened on his death. He was killed on May 12, 1970: "If you are reading this letter, you will never see me again, the reason being that if you are reading this I have died. The question is whether or not my death has been in vain. The answer is yes. The war that has taken my life and many thousands before me is immoral, unlawful and an atrocity... I had no choice as to my fate. It was predetermined by the war-mongering hypocrites in Washington. As I lie dead, please grant my last request. Help me inform the American people, the silent majority who have not yet voiced their opinions."
In 1967, Vietnam Veterans Against the War was formed. They demonstrated all over America. Many of them were in wheelchairs or on crutches. People watched on television as Vietnam heroes threw away the medals they had won fighting in the war. One shouted: "Here's my merit badges for murder." Another apologized to the Vietnamese people and claimed that: "I hope that someday I can return to Vietnam and help to rebuild that country we tore apart."
