Even a captured enemy is not to be trusted.

A ruler wishing to win should not trust a cunning enemy, even if he may be extending a hand of friendship. Because deep-rooted enmity, however, concealed, will surely come to light.

Till the enemy's weakness is known, he should be kept on friendly terms.

Better to have a known enemy than a forced ally.

Every word and deed must contribute to an understanding with the enemy and release those vast reservoirs of goodwill which have been blocked by impenetrable walls of hate.

It is an approved maxim in war, never to do what the enemy wishes you to do, for this reason alone, that he desires it.
