The supreme art of war is to subdue the enemy without fighting.
The art of war teaches us to rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.
If you know the enemy and know yourself you need not fear the results of a hundred battles.
Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.
Know thy self, know thy enemy. A thousand battles, a thousand victories.
