“John Cabal: If we don’t end war, war will end us.”

Statement, sometimes dated to have been made in 1916, as quoted in Reading, Writing and Remembering : A Literary Record (1932) by Edward Verrall Lucas, p. 296

1961, UN speech
Context: Mankind must put an end to war — or war will put an end to mankind.
So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.
Context: We meet in an hour of grief and challenge. Dag Hammarskjold is dead. But the United Nations lives. His tragedy is deep in our hearts, but the task for which he died is at the top of our agenda. A noble servant of peace is gone. But the quest for peace lies before us.
The problem is not the death of one man — the problem is the life of this organization. It will either grow to meet the challenges of our age, or it will be gone with the wind, without influence, without force, without respect. Were we to let it die, to enfeeble its vigor, to cripple its powers, we would condemn our future. For in the development of this organization rests the only true alternative to war — and war appeals no longer as a rational alternative. Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes. It can no longer concern the great powers alone. For a nuclear disaster, spread by wind and water and fear, could well engulf the great and the small, the rich and the poor, the committed and the uncommitted alike. Mankind must put an end to war — or war will put an end to mankind.
So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.

Japan, The Ambiguous, and Myself (1994)
Context: After the end of the Second World War it was a categorical imperative for us to declare that we renounced war forever in a central article of the new Constitution. The Japanese chose the principle of eternal peace as the basis of morality for our rebirth after the War.
I trust that the principle can best be understood in the West with its long tradition of tolerance for conscientious rejection of military service. In Japan itself there have all along been attempts by some to obliterate the article about renunciation of war from the Constitution and for this purpose they have taken every opportunity to make use of pressures from abroad. But to obliterate from the Constitution the principle of eternal peace will be nothing but an act of betrayal against the peoples of Asia and the victims of the Atom Bombs in Hiroshima and Nagasaki.
