Abraham Lincoln, November 19 1863
Four score and seven years ago our fathers brought forth upon this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.
Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.

Roosevelt, declaration of war
FDR Roosevelt, a day after Pearl Harbour
Yesterday, December 7, 1941 a date which will live in infamy the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.
The United States was at peace with that Nation and, at the solicitation of Japan, was still in conversation with its Government and its Emperor looking toward the maintenance of peace in the Pacific. Indeed, one hour after Japanese air squadrons had commenced bombing in the American Island of Oahu, the Japanese Ambassador to the United States and his colleague delivered to our Secretary of State a formal reply to a recent American message. And while this reply stated that it seemed useless to continue the existing diplomatic negotiations, it contained no threat or hint of war or of armed attack.

Adolf Hitler, 23rd March 1933
Marxist organizations seized the executive power by means of a revolution. The monarchs were dethroned, the authorities of the Reich and of the States removed from office, and thereby a breach of the Constitution was committed. The success of the revolution in a material sense protected the guilty parties from the hands of the law. They sought to justify it morally by asserting that Germany or its Government bore the guilt for the outbreak of the War.

Bobby Seale, 23rd March 1933
We have to fight it, we have to deal with this hog, we have to deal with this pig, we have to deal with and understand the situation. We have to understand that when Huey P. Newton says that power is the ability to define phenomena and make it act in a desired manner, that when Huey P. Newton gives this functional definition of power he’s talking about power in the real sense. He’s not talking about green power which is a shuck.

I Have a Dream
Martin Luther King, 28th August 1963
I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.
I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression will be transformed into an oasis of freedom and justice.
I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today.
