On starting a war: ``He should not fight against an alliance of enemy states ... He must try to win the confidence of those who can serve his purpose and also inspire fear in the hearts and minds of his enemies.
``Do not resort to war unless there is some definite advantage to be gained and there is strong assurance of victory ... a state once destroyed cannot be restored and a man killed cannot be brought back to life.''
On ending a war:
``Do not stop the enemy if they are determined to return home. When laying siege, leave them a way of retreat. Do not drive an enemy to desperation.
``If an army finds itself in a desperate position, it will struggle to survive; when threatened with death men will fight for their lives.''
