You have enemies? Good. That means you've stood up for something, sometime in your life.

To know your Enemy, you must become your Enemy.

Build your opponent a golden bridge to retreat across.

If your opponent is of choleric temperament, seek to irritate him.

Speed is the essence of war. Take advantage of the enemy's unpreparedness; travel by unexpected routes and strike him where he has taken no precautions.

To a surrounded enemy, you must leave a way of escape.

It is said that if you know your enemies and know yourself, you will not be imperilled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperilled in every single battle.

Never give in — never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy. Speech given at Harrow School (1941-10-29).

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

When the enemy is at ease, be able to weary him; when well fed, to starve him; when at rest, to make him move. Appear at places to which he must hasten; move swiftly where he does not expect you.

May God have mercy upon my enemies, because I sure as hell won't.

And therefore those skilled in war bring the enemy to the field of battle and are not brought there by him.

There is only one tactical principle which is not subject to change. It is to use the means at hand to inflict the maximum amount of wound, death, and destruction on the enemy in the minimum amount of time.

Wars would be a lot better, I think, if guys would say to themselves sometimes 'Jesus - I'm not going to do that to the enemy. That's too much.'

Forgive your enemies, but never forget their names.

The great enemy of the truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic. Commencement address, Yale University, New Haven, Connecticut (11 June 1962)

The man of knowledge must be able not only to love his enemies but also to hate his friends.

We have the finest food, the finest equipment, the best spirit, and the best men in the world. Why, by God, I actually pity those poor sons-of-bitches we're going up against. By God, I do.

Art is not made to decorate rooms. It is an offensive and defensive weapon against the enemy.

I don't want to get any messages saying, "I am holding my position." We are not holding a Goddamned thing. Let the Germans do that. We are advancing constantly and we are not interested in holding onto anything, except the enemy's balls. We are going to twist his balls and kick the living shit out of him all of the time. Our basic plan of operation is to advance and to keep on advancing regardless of whether we have to go over, under, or through the enemy. We are going to go through him like crap through a goose; like shit through a tin horn!

Remember that the enemy is just as frightened as you are, and probably more so. They are not supermen.

Now is no time to be making new enemies. When asked on his deathbed by a priest to renounce the devil and turn to God.

Always forgive your enemies; nothing annoys them so much.

Enemies are so stimulating.

Conformity is the jailer of freedom and the enemy of growth. Address to the UN General Assembly (25 September 1961)
