Philosophical warfare

One site that I like to visit is Ask Philosophers, a place where you can pose a question and it is answered by philosophers.

Recently a visitor to the site asked, "How do the philosophers justify war, if they ever do? I ask this question because even the Prophets have fought wars, for their religion. So, how can mortals remain aloof from it?"

That's pretty cool and leads me to believe that if all people could practice non-violent resistance Justly then there would never be a useful conquest, except in terms of geographical expansion.
