An Enemy (n.) acts in character — what else should he do?
An Enemy (n.) is tomorrow's most faithful ally: Rome's truest friends were its most stubborn foes.
Enemy (n.) is often made, not acquired: masters are not sold hostile slaves, they turn them hostile.
An Enemy (n.) will die without your turning a hair — you waste effort trying to cause what is anyway going to be.
Enemy (n.) can become more indispensable than a homeland: Hannibal could manage without a country, but never without someone to fight.
An Enemy (n.) does not arrive with the slave: 'As many enemies as you have slaves' — they are not enemies when we acquire them; we make them so.
