We know war happens all the time, unfortunately.  Caught up in war are states and individuals who wish for others to see their actions as reasonable, for the best, and ultimately just. But it seems war involves many actions which are considered wrong in other circumstances, killing another human being for example.  Most people will agree that self-defense is justifiable, but how far does that defense go before it becomes vengeance? And a particular difficulty for aggressor states is that they must have just cause to be the instigator of warfare.  In this episode we turn to the Greeks and the Peloponnesian War, as well as the Medieval giants of Augustine and Aquinas who develop something quite important: Just War Theory. When should war be waged? How should it be conducted? And in it's conclusion, how should the victor treat the defeated.
