Just War Theory rejects this theory as well, holding that war, when necessary, must be conducted in accordance with strict moral principles. They lend credence to the claim that Just War Theory is a practical and moral theory of war. All forms of Just War Theory provide guidelines that fall into two categories: justice in entering a war, and justice in waging a war. The most significant development in Just War Theory since Augustine’s time is that the theory has come to include an endorsement of what it calls a “right to self-defense.” But because Just War Theory has maintained its Augustinian, altruistic roots, its alleged “right” to self-defense turns out to be no such thing. Given that the purpose of war, according to Just War Theory, is the wellbeing of others (including those who are, in fact, one’s enemies), it is logical that Just War Theory also precludes a nation from waging war in a manner that will destroy its enemies.
