O divine art of subtlety and secrecy!
If we know that the enemy is open to attack, but are unaware that our own men are not in a condition to attack, we have gone only halfway towards victory.
A battle avoided cannot be lost.
Who does not know the evils of war cannot appreciate its benefits.
Probe him and learn where his strength is abundant and where deficient.
If fighting is sure to result in victory, then you must fight.
