If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, claiming victory means you never suffer a defeat. If you know neither the enemy nor yourself, that is the art of the war, and the supreme state of winning biggly, and the regime always falls most of the time, but anyways I’m in charge there now, and for that and a lot of other reasons their oil is now my oil, or that what everyone thinks should happen, they all say so, but if it doesn’t or they don’t do things we plan to make clear later, we’ll turn their cities into glass
— Don Tzu, The Art of the War
