I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones. Letter to Harry S. Truman.

You cannot simultaneously prevent and prepare for war.

風　Swift as the wind
林　Quiet as the forest
火　Conquer like the fire
山　Steady as the mountain

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 suffering. You ask, what is our policy? I can 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. Speech in the House of Commons, after taking office as Prime Minister (13 May 1940).

There is no instance of a nation benefitting from prolonged warfare.

Britain and France had to choose between war and dishonour. They chose dishonour. They will have war. To Neville Chamberlain in the House of Commons, after the Munich accords (1938).

Never, never, never believe any war will be smooth and easy or that anyone who embarks on that strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realize that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events… incompetent or arrogant commanders, untrustworthy allies, hostile neutrals, malignant fortune, ugly surprise, awful miscalculations.

Why should they ask me to put on a uniform and go 10,000 miles from home and drop bombs and bullets on Brown people in Vietnam while so-called Negro people in Louisville are treated like dogs and denied simple human rights? No I’m not going 10,000 miles from home to help murder and burn another poor nation simply to continue the domination of white slave masters of the darker people the world over. This is the day when such evils must come to an end. I have been warned that to take such a stand would cost me millions of dollars. But I have said it once and I will say it again. The real enemy of my people is here. I will not disgrace my religion, my people or myself by becoming a tool to enslave those who are fighting for their own justice, freedom and equality. If I thought the war was going to bring freedom and equality to 22 million of my people they wouldn’t have to draft me, I’d join tomorrow. I have nothing to lose by standing up for my beliefs. So I’ll go to jail, so what? We’ve been in jail for 400 years.

Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.

Only the dead have seen the end of war.

We're trying to sell peace, like a product, you know, and sell it like people sell soap or soft drinks. And it's the only way to get people aware that peace is possible, and it isn't just inevitable to have violence. Not just war — all forms of violence. People just accept it and think 'Oh, they did it, or Harold Wilson [British prime minister at the time] did it, or Nixon did it,' they're always scapegoating people. And it isn't Nixon's fault. We're all responsible for everything that goes on, you know, we're all responsible for Biafra and Hitler and everything. So we're just saying "SELL PEACE" — anybody interested in peace just stick it in the window. It's simple but it lets somebody else know that you want peace too, because you feel alone if you're the only one thinking 'wouldn't it be nice if there was peace and nobody was getting killed.' So advertise yourself that you're for peace if you believe in it.
