“Absolute peace in our world is an unattainable goal. But it is one towards which we must continue to journey, our eyes fixed on it as a traveller in a desert fixes his eyes on the one guiding star that will lead him to salvation. Even if we do not achieve perfect peace on earth, because perfect peace is not of this earth, common endeavours to gain peace will unite individuals and nations in trust and friendship and help to make our human community safer and kinder.”

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, Remarks Prepared for Delivery at the Trade Mart in Dallas
Context: We in this country, in this generation, are — by destiny rather than choice — the watchmen on the walls of world freedom. We ask, therefore, that we may be worthy of our power and responsibility, that we may exercise our strength with wisdom and restraint, and that we may achieve in our time and for all time the ancient vision of "peace on earth, good will toward men". That must always be our goal, and the righteousness of our cause must always underlie our strength. For as was written long ago: "except the Lord keep the city, the watchman waketh but in vain."

1963, American University speech
Context: I have, therefore, chosen this time and this place to discuss a topic on which ignorance too often abounds and the truth is too rarely perceived — yet it is the most important topic on earth: world peace. What kind of peace do I mean? What kind of peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children — not merely peace for Americans but peace for all men and women — not merely peace in our time but peace for all time.
