Keep your friends close, and your enemies closer.

To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.

War is based on deception.

The best victory is when the opponent surrenders of its own accord before there are any actual hostilities...It is best to win without fighting.

Nothing is more difficult than the art of maneuvering for advantageous positions.

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

Appraise war in terms of the fundamental factors. The first of these factors is moral influence.

If you are near the enemy, make him believe you are far from him. If you are far from the enemy, make him believe you are near.

All warfare is based on deception. There is no place where espionage is not used. Offer the enemy bait to lure him.

Be extremely subtle, even to the point of formlessness. Be extremely mysterious, even to the point of soundlessness. Thereby you can be the director of the opponent's fate.

A military operation involves deception. Even though you are competent, appear to be incompetent. Though effective, appear to be ineffective.

If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
