Let our friends perish, provided that our enemies fall at the same time.

Your enemies can kill you, but only your friends can hurt you.

If our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right.

Wars, therefore, are to be undertaken for this end, that we may live in peace, without being injured; but when we obtain the victory, we must preserve those enemies who behaved without cruelty or inhumanity during the war.
