“If the people raise a howl against my barbarity and cruelty, I will answer that war is war, and not popularity-seeking. If they want peace, they and their relatives must stop the war.”

"Why Are We in Kosovo?", The New York Times (2 May 1999)
Context: Stop the War and Stop the Genocide, read the banners being waved in the demonstrations in Rome and here in Bari. For Peace. Against War. Who is not? But how can you stop those bent on genocide without making war?

a computer-generated Oliphaunt steps on Moore, crushing him
In a humorous sendup of Moore's previous acceptance speech for Best Documentary Feature at the 2003 Oscars. Moore himself delivered the lines in the opening act of the 2004 Oscars, while standing in front of a greenscreen which had the Battle of the Pelennor Fields scene from The Lord of the Rings: The Return of the King playing on it; a battle which was, itself, literally fictitious.

Speaking in Carnegie Hall, New York City, on 4 April 1919.

Context: As a soldier who has spent a quarter of his life in the study of the science of arms, let me tell you I went into the British Army believing that if you want peace you must prepare for war. I believe now that if you prepare thoroughly and efficiently for war, you get war.

Guerrilla Warfare (1960)

1860s, 1864, Letter to the City of Atlanta (September 1864)
Source: Memoirs of General W.T. Sherman
Context: You cannot qualify war in harsher terms than I will. War is cruelty, and you cannot refine it; and those who brought war into our country deserve all the curses and maledictions a people can pour out. I know I had no hand in making this war, and I know I will make more sacrifices today than any of you to secure peace. But you cannot have peace and a division of our country. If the United States submits to a division now, it will not stop

If the United States submits to a division now, it will not stop, but will go on until we reap the fate of Mexico, which is eternal war. The United States does and must assert its authority, wherever it once had power; for, if it relaxes one bit to pressure, it is gone, and I believe that such is the national feeling.

Preface to Food for the Spirit: Vegetarianism and the World Religions by Steven Rosen (New York: Bala Books, 1987, )
Variant: To be a vegetarian is to disagree - to disagree with the course of things today... starvation, cruelty - we must make a statement against these things. Vegetarianism is my statement. And I think it's a strong one.
Context: Vegetarianism is my religion. I became a consistent vegetarian some twenty-three years ago. Before that, I would try over and over again. But it was sporadic. Finally, in the mid-1960s, I made up my mind. And I've been a vegetarian ever since. When a human kills an animal for food, he is neglecting his own hunger for justice. Man prays for mercy, but is unwilling to extend it to others. Why should man then expect mercy from God? It's unfair to expect something that you are not willing to give. … This is my protest against the conduct of the world. To be a vegetarian is to disagree — to disagree with the course of things today. Nuclear power, starvation, cruelty — we must make a statement against these things. Vegetarianism is my statement. And I think it's a strong one.
