Sun Tzu's Art of War, Chapter 4, emphasizes strategic preparation for victory. Invincibility, achieved through meticulous planning and defense, precedes offensive action. Success hinges on understanding the terrain, resources, and enemy capabilities, culminating in a decisive advantage. True mastery, however, lies not in obvious triumphs, but in effortless victories born from superior planning and foresight, effectively ensuring the enemy's defeat before battle even commences. This systematic approach, guided by moral and practical principles, governs the outcome of war.
