Great is the guilt of an unnecessary war.

Yippies, Hippies, Yahoos, Black Panthers, lions and tigers alike - I would swap the whole damn zoo for the kind of young Americans I saw in Vietnam.

There was never a bad peace or a good war.

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

When men take up arms to set other men free, there is something sacred and holy in the warfare.

The supreme art of war is to subdue the enemy without fighting.

Either war is obsolete, or men are.

War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse.

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

Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win

You don't reason with intellectuals. You shoot them.

Brutality to an animal is cruelty to mankind - it is only the difference in the victim.

Everyone’s worried about stopping terrorism. Well, there’s really an easy way: Stop participating in it.

Never was anything great achieved without danger

When you surround an army, leave an outlet free. Do not press a desperate foe too hard.

Ideas are far more powerful than guns. We don't let our people have guns. Why should we let them have ideas?

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

There is no instance of a nation benefiting from prolonged warfare

I have nothing to offer but blood, toil, tears and sweat.

Never forget that everything Hitler did in Germany was legal.

Know yourself and you will win all battles.
