The question refers to Beyond Vietnam: A Speech Against Vietnam War, delivered by Martin Luther King Jr. on April 4, 1967; it is also known as the Riverside Church Speech because of the location used to deliver it. The five proposals are 1) end the bombing; 2) unilateral cease-fire by the U.S.; 3) shorten the development of U.S. troops in Thailand and Laos; 4) the National Liberation Front must be recognized as a legitimate part during the negotiations; 5) set a date for withdrawal. In the previous part, King quotes a Buddhist leader that criticized how the U.S. had used its military power against Vietnamese people and how it stopped America of being a revolutionary country for freedom.
