Opposition to the Vietnam War
King was long opposed to American involvement in the Vietnam War, but at first avoided the topic in speeches to avoid interference with civil rights goals that criticism of President Johnson's policies might have created. At the urging of SCLC's former Director of Direct Action and now the head of the Spring Mobilization Committee to End the War in Vietnam, James Bevel, and inspired by the outspokenness of Muhammad Ali, King eventually agreed to publicly oppose the war, as opposition was growing among the public.
During an April 1967 appearance at the New York City Riverside Church, King delivered a speech titled "Beyond Vietnam: A Time to Break Silence". He spoke against America's role in the war, arguing the US was in Vietnam "to occupy it as an American colony" and calling the US government "the greatest purveyor of violence in the world today". He connected the war with economic injustice, arguing that the country needed serious moral change:
A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look across the seas and see individual capitalists of the West investing huge sums of money in Asia, Africa and South America, only to take the profits out with no concern for the social betterment of the countries, and say: "This is not just."
King opposed the war because it took resources away from social welfare at home: "A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death." He stated that North Vietnam "did not begin to send in any large number of supplies or men until American forces had arrived in the tens of thousands", and accused the U.S. of having killed a million Vietnamese, "mostly children". King also criticized American opposition to North Vietnam's land reforms.
King's opposition cost him significant support among white allies including Johnson, Billy Graham, union leaders, and powerful publishers. "The press is being stacked against me", King said, complaining of what he described as a double standard that applauded his nonviolence at home, but deplored it when applied "toward little brown Vietnamese children". Life magazine called the speech "demagogic slander that sounded like a script for Radio Hanoi", and The Washington Post declared that King had "diminished his usefulness to his cause, his country, his people."
The "Beyond Vietnam" speech reflected King's evolving political advocacy in his later years, which paralleled the teachings of the progressive Highlander Research and Education Center, with which he was affiliated. King began to speak of the need for fundamental changes in the American political and economic situation, and more frequently expressed his opposition to the war and his desire to see a redistribution of resources to correct injustice. He guarded his language in public to avoid being linked to communism, but in private sometimes spoke of his support for democratic socialism.
King stated in "Beyond Vietnam" that "true compassion is more than flinging a coin to a beggar ... it comes to see that an edifice which produces beggars needs restructuring." King quoted a US official who said that from Vietnam to Latin America, the country was "on the wrong side of a world revolution." King condemned America's "alliance with the landed gentry of Latin America", and said the US should support "the shirtless and barefoot people" in the Third World rather than suppressing their attempts at revolution.
King's stance on Vietnam encouraged Allard K. Lowenstein, William Sloane Coffin and Norman Thomas, with the support of anti-war Democrats, to attempt to persuade King to run against President Johnson in the 1968 presidential election. King contemplated but decided against this as he felt uneasy with politics and considered himself better suited to activism.
On April 15, 1967, King spoke at an anti-war march from Manhattan's Central Park to the UN. The march was organized by the Spring Mobilization Committee to End the War in Vietnam under chairman James Bevel. At the UN King brought up issues of civil rights and the draft:
I have not urged a mechanical fusion of the civil rights and peace movements. There are people who have come to see the moral imperative of equality, but who cannot yet see the moral imperative of world brotherhood. I would like to see the fervor of the civil-rights movement imbued into the peace movement to instill it with greater strength. And I believe everyone has a duty to be in both the civil-rights and peace movements. But for those who presently choose but one, I would hope they will finally come to see the moral roots common to both.
Seeing an opportunity to unite civil rights and anti-war activists, Bevel convinced King to become even more active in the anti-war effort. Despite his growing public opposition to the war, King was not fond of the hippie culture developed from the anti-war movement. In his 1967 Massey Lecture, King stated:
The importance of the hippies is not in their unconventional behavior, but in the fact that hundreds of thousands of young people, in turning to a flight from reality, are expressing a profoundly discrediting view on the society they emerge from.
On January 13, 1968, King called for a large march on Washington against "one of history's most cruel and senseless wars":
We need to make clear in this political year, to congressmen on both sides of the aisle and to the president of the United States, that we will no longer tolerate, we will no longer vote for men who continue to see the killings of Vietnamese and Americans as the best way of advancing the goals of freedom and self-determination in Southeast Asia.
Thích Nhất Hạnh was an influential Vietnamese Buddhist who wrote a letter to King in 1965 entitled: "In Search of the Enemy of Man". It was during his 1966 stay in the US that Nhất Hạnh met with King and urged him to publicly denounce the war. On April 4, 1967, King gave a speech in New York City, his first to publicly question U.S. involvement in Vietnam. Later that year, King nominated Nhất Hạnh for the Nobel Peace Prize. In his nomination, King said, "I do not personally know of anyone more worthy of [this prize] than this gentle monk from Vietnam. His ideas for peace, if applied, would build a monument to ecumenism, to world brotherhood, to humanity".
