“Those who cherish their freedom and recognize and respect the equal right of their neighbors to be free and live in peace must work together for the triumph of law and moral principles in order that peace, justice, and confidence may prevail in the world.”

1960, Address at Convention Hall, Philadelphia
Context: In short, I believe in an America that is on the march — an America respected by all nations, friends and foes alike — an America that is moving, doing, working, trying — a strong America in a world of peace. That peace must be based on world law and world order, on the mutual respect of all nations for the rights and powers of others and on a world economy in which no nation lacks the ability to provide a decent standard of living for all of its people. But we cannot have such a world, and we cannot have such a peace, unless the United States has the vitality and the inspiration and the strength. If we continue to stand still, if we continue to lie at anchor, if we continue to sit on dead center, if we content ourselves with the easy life and the rosy assurances, then the gates will soon be open to a lean and hungry enemy.

1950s, Second Inaugural Address (1957)
Context: We look upon this shaken Earth, and we declare our firm and fixed purpose — the building of a peace with justice in a world where moral law prevails. The building of such a peace is a bold and solemn purpose. To proclaim it is easy. To serve it will be hard. And to attain it, we must be aware of its full meaning — and ready to pay its full price. We know clearly what we seek, and why. We seek peace, knowing that peace is the climate of freedom. And now, as in no other age, we seek it because we have been warned, by the power of modern weapons, that peace may be the only climate possible for human life itself. Yet this peace we seek cannot be born of fear alone: it must be rooted in the lives of nations. There must be justice, sensed and shared by all peoples, for, without justice the world can know only a tense and unstable truce. There must be law, steadily invoked and respected by all nations, for without law, the world promises only such meager justice as the pity of the strong upon the weak. But the law of which we speak, comprehending the values of freedom, affirms the equality of all nations, great and small. Splendid as can be the blessings of such a peace, high will be its cost: in toil patiently sustained, in help honorably given, in sacrifice calmly borne.

1963, American University speech
Context: World peace, like community peace, does not require that each man love his neighbor — it requires only that they live together in mutual tolerance, submitting their disputes to a just and peaceful settlement. And history teaches us that enmities between nations, as between individuals, do not last forever. However fixed our likes and dislikes may seem, the tide of time and events will often bring surprising changes in the relations between nations and neighbors.
