Martin Luther King - A Time to Break Silence
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."
"Now, it should be incandescently clear that no one who has any concern for the integrity and life of America today can ignore the present war. If America's soul becomes totally poisoned, part of the autopsy must read: Vietnam. It can never be saved so long as it destroys the deepest hopes of men the world over. So it is that those of us who are yet determined that America will be are led down the path of protest and dissent, working for the health of our land."
"At this point I should make it clear that while I have tried in these last few minutes to give a voice to the voiceless in Vietnam and to understand the arguments of those who are called "enemy," I am as deeply concerned about our own troops there as anything else. For it occurs to me that what we are submitting them to in Vietnam is not simply the brutalizing process that goes on in any war where armies face each other and seek to destroy. We are adding cynicism to the process of death, for they must know after a short period there that none of the things we claim to be fighting for are really involved. Before long they must know that their government has sent them into a struggle among Vietnamese, and the more sophisticated surely realize that we are on the side of the wealthy, and the secure, while we create a hell for the poor."

Martin Luther King, Jr. (January 15, 1929 -- April 4, 1968), was one of the main leaders of the American civil rights movement. A Baptist minister by training, King became a civil rights activist early in his career, leading the Montgomery Bus Boycott and helping to found the Southern Christian Leadership Conference. His efforts led to the 1963 March on Washington, where King delivered his "I Have a Dream" speech, raising public consciousness of the civil rights movement and establishing King as one of the greatest orators in American history. In 1964, King became the youngest person to receive the Nobel Peace Prize for his efforts to end segregation and racial discrimination through civil disobedience and other non-violent means.

Dr. King was assassinated on April 4, 1968, in Memphis, Tennessee. He was posthumously awarded the Presidential Medal of Freedom by President Jimmy Carter in 1977. Martin Luther King Day was established as a national holiday in the United States in 1986. In 2004, King was posthumously awarded a Congressional Gold Medal.
