“Disaster, by definition, is failing to capitalize on your achievements despite victory in battle and seizure of the spoils. As the phrase goes, 'He who hesitates is lost.' Hence the saying, 'The brilliant rulers thinks it through, while good commanders refine the plan.'

When nought's to gain, move not.
Over things of little worth, fight not.
Save in direst need, war not.

A ruler cannot call up armies in a rage nor can his commanders start a war over a slight. They move only if it is to their advantage. They bide their time, if it is not. A person in a rage can be restored to good humor, and someone mortally offended can be restored to affability. By contrast, a kingdom, once destroyed, cannot be restored, nor can the dead be brought back to life. Thus the brilliant ruler approaches battle with due prudence, and good commanders are ever on their guard. This is the way to secure the ruling house and keep the army intact.”
