And religious people state that this must be a "just war."
What is a "just war?" Where did this idea or concept come from? And what relevance does it have in the twenty-first century and in dealing with fanaticism and terrorist elements?
Most scholars point to St. Augustine of Hippo as the formulator of the Doctrine of the Just War. Extrapolated from The City of God, the principles have been formulated into these eight statements:

+ The reason for the war must be to redress rights actually violated or to defend against unjust demands backed by force.
+ The war must be openly and legally declared by a lawful government.
+ There must be a reasonable chance of winning.
+ Soldiers must try to distinguish between armies and civilians and never kill civilians on purpose.
+ The means used in fighting the war must be "proportionate" to the end sought.
+ The good to be done by the war must outweigh the evil which the war would do.
+ The winner must never require the utter humiliation of the loser.
