I know war as few other men now living know it, and nothing to me is more revolting. I have long advocated its complete abolition, as its very destructiveness on both friend and foe has rendered it useless as a method of settling international disputes.
If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.
The best way to fight evil is to do some good. Let me qualify that—the best way to fight evil at home is to do some good. The best way to fight them abroad is to unleash the military.
The essential factor of military success is speed, that is taking advantage of others' unpreparedness or lack of foresight, their failure to catch up, going by routes they do not expect, attacking where they are not on guard. This you cannot accomplish with hesitation.
When any kind of military action is popular it's because either there's been a very clear, direct threat to us - 9/11 - or an administration uses various hooks to suggest that American interests were directly threatened - like in Panama or Grenada. And sometimes, those hooks are more persuasive than others, but typically, they're not put before Congress.
What is a war criminal? Was not war itself a crime against God and humanity, and, therefore, were not all those who sanctioned, engineered, and conducted wars, war criminals? War criminals are not confined to the Axis Powers alone. Roosevelt and Churchill are no less war criminals than Hitler and Mussolini. England, America and Russia have all of them got their hands dyed more or less red - not merely Germany and Japan.
Spies cannot be usefully employed without a certain intuitive sagacity; They cannot be properly managed without benevolence and straightforwardness; Without subtle ingenuity of mind, one cannot make certain of the truth of their reports; Be subtle! be subtle! and use your spies for every kind of warfare; If a secret piece of news is divulged by a spy before the time is ripe, he must be put to death together with the man to whom the secret was told.
