Art of War

Sun Tzu considered war as a necessary evil that must be avoided whenever possible. The war should be fought swiftly to avoid economic losses: "No long war ever profited any country: 100 victories in 100 battles is simply ridiculous. Anyone who excels in defeating his enemies triumphs before his enemy's threats become real".

Sun Tzu emphasized the importance of positioning in military strategy. The decision to position an army must be based on both objective conditions in the physical environment and the subjective beliefs of other, competitive factors in that environment. He thought that strategy was not planning in the sense of working through an established list, but rather that it requires quick and appropriate responses to changing conditions. Planning works in a controlled environment; but in a changing environment, competing plans collide, creating unexpected situations.
