We have neither peace within nor peace without. Everywhere paralyzing fears harrow people by day and haunt them by night. Our world is sick with war; everywhere we turn we see its ominous possibilities. And yet, my friends, the Christmas hope for peace and good will toward all men can no longer be dismissed as a kind of pious dream of some utopian. If we don’t have good will toward men in this world, we will destroy ourselves by the misuse of our own instruments and our own power. Wisdom born of experience should tell us that war is obsolete. There may have been a time when war served as a negative good by preventing the spread and growth of an evil force, but the very destructive power of modern weapons of warfare eliminates even the possibility that war may any longer serve as a negative good. And so, if we assume that life is worth living, if we assume that mankind has a right to survive, then we must find an alternative to war and so let us this morning explore the conditions for peace. Let us this morning think anew on the meaning of that Christmas hope: “Peace on Earth, Good Will toward Men.” And as we explore these conditions, I would like to suggest that modern man really go all out to study the meaning of nonviolence, its philosophy and its strategy.
We have experimented with the meaning of nonviolence in our struggle for racial justice in the United States, but now the time has come for man to experiment with nonviolence in all areas of human conflict, and that means nonviolence on an international scale. — MLK, A Christmas Sermon on Peace, 1967
