How do you defeat terrorism? Don’t be terrorized.

In war, as in life, it is often necessary, when some cherished scheme has failed, to take up the best alternative open, and if so, it is folly not to work for it with all your might.

Those who play with the devil's toys will be brought by degrees to wield his sword.

The end move in politics is always to pick up a gun.

There was never a bad peace or a good war.

There is no instance of a nation benefiting from prolonged warfare

Know your enemy and know yourself and you will always be victorious

Any alliance whose purpose is not the intention to wage war is senseless and useless.

Either war is obsolete, or men are.

Never think that war, no matter how necessary, nor how justified, is not a crime.

All the war-propaganda, all the screaming and lies and hatred, comes invariably from people who are not fighting.

Everything in war is very simple. But the simplest thing is difficult.

As soon as men decide that all means are permitted to fight an evil, then their good becomes indistinguishable from the evil that they set out to destroy.

War is just when it is necessary; arms are permissible when there is no hope except in arms.

Never ascribe to malice that which can adequately be explained by incompetence.

Listen up - there's no war that will end all wars

Never was anything great achieved without danger

I don't like war. I particularly don't like the celebration of war, which I think the administration is a little bit guilty of.

Demoralize the enemy from within by surprise, terror, sabotage, assassination. This is the war of the future.

There is a road from the eye to the heart that does not go through the intellect.

All the forces in the world are not so powerful as an idea whose time has come.
