“In the name of liberty you have done what liberty disowns. In the name of theoretical progress, you have opened the door to practical retrogression. In the name of appeasement and the popular will, you have prescribed a course of endless irritation. … He has won his victory; he has won the victory for which he has fought hard, and long, and adroitly; but it is not a victory, in our opinion, for the interests of this country, nor a victory for the welfare of the peoples of India, and in the crashing cheers which no doubt will hail his majority to-night, we pray there may not mingle the knell of the British Empire in the East.”

Speech in the House of Commons, after taking office as Prime Minister (13 May 1940) This has often been misquoted in the form: "I have nothing to offer but blood, sweat and tears ..."
The Official Report, House of Commons (5th Series), 13 May 1940, vol. 360, c. 1502. Audio records of the speech do spare out the "It is" before the in the beginning of the "Victory"-Part.
The Second World War (1939–1945)
Context: You ask, what is our policy? I will say: It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us: to wage war against a monstrous tyranny, never surpassed in the dark, lamentable catalogue of human crime. That is our policy. You ask, what is our aim? I can answer in one word: It is victory, victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival.
Context: I would say to the House, as I said to those who have joined this Government: 'I have nothing to offer but blood, toil, tears, and sweat.' We have before us an ordeal of the most grievous kind. We have before us many, many long months of struggle and of suffering. You ask, what is our policy? I will say: It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us: to wage war against a monstrous tyranny, never surpassed in the dark, lamentable catalogue of human crime. That is our policy. You ask, what is our aim? I can answer in one word: It is victory, victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival.

Guru Nanak quotes

Speech regarding Civil Liberties and the War on Terrorism (November 20, 2006)

1940s, Victory broadcast (1945)
Context: Today the guns are silent. A great tragedy has ended. A great victory has been won. The skies no longer rain with death — the seas bear only commerce — men everywhere walk upright in the sunlight. The entire world lies quietly at peace. The holy mission has been completed. And in reporting this to you, the people, I speak for the thousands of silent lips, forever stilled among the jungles and the beaches and in the deep waters of the Pacific which marked the way.

Report on the Potsdam Conference (1945)
Context: Any man who sees Europe now must realize that victory in a great war is not something you win once and for all, like victory in a ball game. Victory in a great war is something that must be won and kept won. It can be lost after you have won it — if you are careless or negligent or indifferent.
Europe today is hungry. I am not talking about Germans. I am talking about the people of the countries which were overrun and devastated by the Germans, and particularly about the people of Western Europe. Many of them lack clothes and fuel and tools and shelter and raw materials. They lack the means to restore their cities and their factories.
As the winter comes on, the distress will increase. Unless we do what we can to help, we may lose next winter what we won at such terrible cost last spring. Desperate men are liable to destroy the structure of their society to find in the wreckage some substitute for hope. If we let Europe go cold and hungry, we may lose some of the foundations of order on which the hope for worldwide peace must rest.
We must help to the limits of our strength. And we will.
