Is a Total War always, sometimes, or never okay?
"Total War" being defined as: A war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, esp. one in which the laws of war are disregarded.
In short: Do ends justify means?
And as a counter point: "War doesn't determine who's right only who is left." Is there any real or moral victory that can be claimed from a war against an entire nation rather than merely against an armed force?
In addition, if such a war be acceptable given a Ius Bellum but not in any other circumstances, what would be due cause for such actions to be taken by a reasonable actor?
