1960s, Nobel Prize acceptance speech (1964)
Context: Nonviolence is the answer to the crucial political and moral questions of our time — the need for mankind to overcome oppression and violence without resorting to violence and oppression. Civilization and violence are antithetical concepts… Sooner or later all the people of the world will have to discover a way to live together in peace, and thereby transform this pending cosmic elegy into a creative psalm of brotherhood. If this is to be achieved, man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.

"A Community of the Free" address at the The Foreign Policy Association NY, NY (23 June 1976); this is often paraphrased: We cannot be both the world’s leading champion of peace and the world’s leading supplier of the weapons of war.
