* War is a matter of vital importance to the state; it is a matter of life or death, survival or ruin.
* War can lead to disaster. Sometimes the best way to win is to not fight at all. This is perhaps Suntzu’s ultimate secret.
Nations often rush to wars with very little concern of thinking through what the total cost is going to be, not only just the dollars, but also in terms of human suffering, not only to you, but also to the civilians and children of the country which you are fighting.
* No nation has ever benefited from prolonged war.
* War is a means to an end. War is not the goal.
* The role of supreme general: a man must be intelligent and cunning, never rash or arrogant, against impulsive behavior, rash behavior.
* Victory comes from deep thinking, from detailed calculation, from long preparation.
* Foreknowledge: the way a wise general can achieve greatness beyond ordinary men is through foreknowledge.
* The winning army realizes the conditions for victory first, then fights. The losing army fights first, then seeks victory.
* Move only when you see an advantage and there is something to gain. Only fight if a position is critical.
* Never throw good money after bad. Never use an attack to rescue a defeat.
* Three key principles:
Know yourself and your enemy.
Subdue enemy without fighting.
Avoid what is strong, attack what is weak.
* Momentum: it is important to maintain momentum.
* Five elements to win: weather, terrain, leadership, military doctrine, moral influence.
* Those skilled in war bring the enemy to the field of battle.
* To move your enemy, give him something he is certain to take.
* When the enemy occupies high ground, do not confront him. If he attacks downhill, do not oppose him.
* There are some armies that should not be fought; some ground that should not be contested.
