Sun-Tzu (if a person of that name really existed) believed that winning over an opponent consisted primarily in knowing that opponent and how one could best use the deficiencies of the enemy to one's advantage in order to end a conflict swiftly with minimal casualties to either side. Today, with international terrorism at the forefront of the news on a daily basis, one would do well to study, and try to learn from, the lessons Sun-Tzu set down in his Art of War.
The link to my article on Sun-Tzu, from Ancient History Encyclopedia, is here:
The piece begins:
Sun Tzu is known as a Chinese military strategist, Taoist philosopher, and general in the 6th century BCE who is widely recognized for his work The Art of War, a treatise on military strategy (also known as The Thirteen Chapters). Whether an individual by the name of `Sun-Tzu’ existed at all has been disputed (in the same way scholars and historians debate the existence of an actual man named Lao-Tzu) but the existence of The Art of War and its profound influence on military campaigns, clearly proves that someone existed to produce said work and that the work is attributed to one Sun-Tzu. The historian Griffith writes:
War, an integral part of the power politics of the age, had become `a matter of vital importance to the state, the province of life and death, the road to survival or ruin’. To be waged successfully, it required a coherent strategic and tactical theory and a practical doctrine governing intelligence, planning, command, operational, and administrative procedures. The author of `The Thirteen Chapters’ was the first man to provide such a theory and such a doctrine. (Griffith, 44).
