“We have differed and quarrelled in the past but now one bond unites us all—to wage war until victory is won, and never to surrender ourselves to servitude and shame, whatever the cost and the agony must be.”

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.

'La vie n’est facile pour aucun de nous. Mais quoi, il faut avoir de la persévérance, et surtout de la confiance en soi. Il faut croire que l’on est doué pour quelque chose, et que, cette chose, il faut l'atteindre coûte que coûte.'
As quoted in Madame Curie : A Biography (1937) by Eve Curie Labouisse, Part 2, p. 116

Michael Moore declares these lines in his film Fahrenheit 9/11 as something "Orwell once wrote". They are nearly identical to a block of voiceover in the 1984 Richard Burton/John Hurt movie version of 1984 when Winston (Hurt) is silently reading Goldstein's book. All of the lines are excerpts from various parts of Goldstein's book in part 2, chapter 9 of the novel with some paraphrasing. Note that the fourth sentence begins with "This new version". In Moore's speech there is no antecedent for this phrase; consequently, the sentence makes no sense there. https://docs.google.com/document/d/1SVrM2Ef81C7EUSTm4zsgjQk9mgMSeFUnlEvtleR2V1w/edit?usp=sharing http://metabunk.org/threads/debunked-war-is-not-meant-to-be-won-it-is-meant-to-be-continuous.1259/

The quote is almost identical to a block of narration from the 1984 movie version of "1984", which is excerpted from various parts of the novel Nineteen Eighty-Four with some paraphrasing.
