"[W]e must find an alternative to war and bloodshed. Anyone who feels, and there are still a lot of people who feel that way, that war can solve the social problems facing mankind is sleeping through a great revolution. President Kennedy said on one occasion, 'Mankind must put an end to war or war will put an end to mankind.' The world must hear this. I pray to God that America will hear this before it is too late, because today we’re fighting a war."
Mankind put an end, both to Martin Luther King, Jr., and JFK. But not to what they said.
