A war can only really be fought against an enemy who shows himself. By infiltrating your opponents’ ranks, working from within to bring them down, you give them nothing to see or react against—the ultimate advantage. From within, you also learn their weaknesses and open up possibilities of sowing internal dissension. So hide your hostile intentions. To take something you want, do not fight those who have it, but rather join them—then either slowly make it your own or wait for the moment to stage a coup d’état. No structure can stand for long when it rots from within.
