Starting in 1965, King began to express doubts about the United States' role in the Vietnam War. In an April 4, 1967, appearance at the New York City Riverside Church — exactly one year before his death — King delivered Beyond Vietnam: A Time to Break Silence. In the speech he spoke strongly against the U.S.'s role in the war, insisting that the U.S. was in Vietnam "to occupy it as an American colony" and calling the U.S. government "the greatest purveyor of violence in the world today." But he also argued that the country needed larger and broader moral changes:
“ 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 was long hated by many white southern segregationists, but this speech turned the more mainstream media against him. Time 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."
With regard to Vietnam, King often claimed 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." King also praised North Vietnam's land reform. He accused the United States of having killed a million Vietnamese, "mostly children."
The speech was a reflection of King's evolving political advocacy in his later years, sparked in part by his affiliation with and training at the progressive Highlander Research and Education Center. King began to speak of the need for fundamental changes in the political and economic life of the nation. Toward the end of his life, King more frequently expressed his opposition to the war and his desire to see a redistribution of resources to correct racial and economic injustice. Though his public language was guarded, so as to avoid being linked to communism by his political enemies, in private he sometimes spoke of his support for democratic socialism:
“ You can't talk about solving the economic problem of the Negro without talking about billions of dollars. You can't talk about ending the slums without first saying profit must be taken out of slums. You're really tampering and getting on dangerous ground because you are messing with folk then. You are messing with captains of industry… Now this means that we are treading in difficult water, because it really means that we are saying that something is wrong… with capitalism… There must be a better distribution of wealth and maybe America must move toward a democratic socialism. ”
King had read Marx while at Morehouse, but while he rejected "traditional capitalism," he also rejected Communism because of its "materialistic interpretation of history" that denied religion, its "ethical relativism," and its "political totalitarianism."
King also stated in his "Beyond Vietnam" speech: "True compassion is more than flinging a coin to a beggar; it comes to see that an edifice which produces beggars needs restructuring." From Vietnam to South Africa to Latin America, King said, the U.S. was "on the wrong side of a world revolution." King questioned "our alliance with the landed gentry of Latin America," and asked why the U.S. was suppressing revolutions "of the shirtless and barefoot people" in the Third World, instead of supporting them.
In 1968, King and the SCLC organized the "Poor People's Campaign" to address issues of economic justice. However, according to the article "Coalition Building and Mobilization Against Poverty", King and SCLC's Poor People's Campaign was not supported by the other leaders of the Civil Rights Movement, including Bayard Rustin. Their opposition incorporated arguments that the goals of Poor People Campaign was too broad, the demands unrealizable, and thought these campaigns would accelerate the backlash and repression on the poor and the black.
The campaign culminated in a march on Washington, D.C. demanding economic aid to the poorest communities of the United States. He crisscrossed the country to assemble "a multiracial army of the poor" that would descend on Washington—engaging in nonviolent civil disobedience at the Capitol, if need be—until Congress enacted a poor people's bill of rights. Reader's Digest warned of an "insurrection."
King's economic bill of rights called for massive government jobs programs to rebuild America's cities. He saw a crying need to confront a Congress that had demonstrated its "hostility to the poor"—appropriating "military funds with alacrity and generosity," but providing "poverty funds with miserliness." His vision was for change that was more revolutionary than mere reform: he cited systematic flaws of racism, poverty, militarism and materialism, and that "reconstruction of society itself is the real issue to be faced."
