“Let us therefore join hands, Britons, Burmans and all nations alike, to build up an abiding fruitful peace over the foundations of the hard-won victory that all of us desiring progressive direction in our own affairs and in the world at large, have at long last snatched firmly and completely from the grabbing hands of Fascist barbarians, a peace, as I have said, not of the graveyard, but creative of freedom, progress and prosperity in the world.”

1990s, Inaugural celebration address (1994)
Context: We are both humbled and elevated by the honour and privilege that you, the people of South Africa, have bestowed on us, as the first President of a united, democratic, non-racial and non-sexist government.
We understand it still that there is no easy road to freedom
We know it well that none of us acting alone can achieve success.
We must therefore act together as a united people, for national reconciliation, for nation building, for the birth of a new world.
Let there be justice for all.
Let there be peace for all.

1963, UN speech
Context: Two years ago I told this body that the United States had proposed, and was willing to sign, a limited test ban treaty. Today that treaty has been signed. It will not put an end to war. It will not remove basic conflicts. It will not secure freedom for all. But it can be a lever, and Archimedes, in explaining the principles of the lever, was said to have declared to his friends: "Give me a place where I can stand — and I shall move the world." My fellow inhabitants of this planet: Let us take our stand here in this Assembly of nations. And let us see if we, in our own time, can move the world to a just and lasting peace.
