“Fondly do we hope — fervently do we pray — that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said, 'The judgments of the Lord are true and righteous altogether.'”

Context: We shall never sheathe the sword, which we have not lightly drawn, until Belgium recovers in full measure all, and more than all, that she has sacrificed; until France is adequately secured against the menace of aggression; until the rights of the smaller nationalities of Europe are placed upon an unassailable foundation; and until the military domination of Prussia is wholly and finally destroyed.

1950s, Loving Your Enemies (Christmas 1957)
Context: Jesus is eternally right. History is replete with the bleached bones of nations that refused to listen to him. May we in the twentieth century hear and follow his words-before it is too late. May we solemnly realize that we shall never be true sons of our heavenly Father until we love our enemies and pray for those who persecute us.

The Intelligent Woman's Guide To Socialism, Capitalism, Sovietism, and Fascism (1928)
1920s
Context: It is far more likely that by the time nationalization has become the rule, and private enterprise the exception, Socialism (which is really rather a bad name for the business) will be spoken of, if at all, as a crazy religion held by a fanatical sect in that darkest of dark ages, the nineteenth century. Already, indeed, I am told that Socialism has had its day, and that the sooner we stop talking nonsense about it and set to work, like the practical people we are, to nationalize the coal mines and complete a national electrification scheme, the better. And I, who said forty years ago that we should have had Socialism already but for the Socialists, am quite willing to drop the name if dropping it will help me to get the thing. What I meant by my jibe at the Socialists of the eighteen-eighties was that nothing is ever done, and much is prevented, by people who do not realize that they cannot do everything at once.

Report on the Potsdam Conference (1945)
Context: I realize the tragic significance of the atomic bomb. Its production and its use were not lightly undertaken by this Government. But we knew that our enemies were on the search for it. We know now how close they were to finding it. And we knew the disaster which would come to this Nation, and to all peace-loving nations, to all civilization, if they had found it first. That is why we felt compelled to undertake the long and uncertain and costly labor of discovery and production. We won the race of discovery against the Germans.
Having found the bomb we have used it. We have used it against those who attacked us without warning at Pearl Harbor, against those who have starved and beaten and executed American prisoners of war, against those who have abandoned all pretense of obeying international laws of warfare. We have used it in order to shorten the agony of war, in order to save the lives of thousands and thousands of young Americans. We shall continue to use it until we completely destroy Japan's power to make war. Only a Japanese surrender will stop us.
