As Sun Tzu asserts in his book titled The Art of War, ”it says” ”In the practical art of war, the best thing of all is to take the enemy's country whole and inact; to shatter and destroy it is not so profitable. So, too, it is better to capture an army entire than to destroy it, to capture a regiment a detachment or a company entire than to annihilate them.” Sun also concludes that a commander should fight with wholeness and intactness in his mind to prevent his troops from casualties and to keep his interest whole and intact. However, who is the one to be kept whole and intact? Enemy, his own troops, or both? This article will provide a modern perspective on this issue via a rational approach, which is frequently used in economics and Game Theory to justify the standpoint that the one who should be kept whole and intact is the enemy.
