Use force with caution in the Tao

Those who assist a ruler by the Tao do not use military force to dominate the world. War is the kind of thing that easily backfires. Where armies have camped, thorns and brambles grow. After a great war, there are sure to be years of famine. A skilled military leader aims only to accomplish the mission and then stops. He does not dare use force to show off his strength. He accomplishes the mission without arrogance. He accomplishes the mission without boasting. He accomplishes the mission without pride. He acts only because he has no choice. After winning, he does not press his advantage or act tough. When things reach the peak of their strength, they begin to age. This is contrary to the Tao. And whatever is contrary to the Tao soon comes to an end.
