Who? You're quoting fancy philosophical terms, so here goes: Aristotle: the sort of war that involves hunting “those human beings who are naturally suited to be ruled but [are] unwilling…[is] by nature just” Plato's Republic had warriors as a vital part of his ideal society. Aquinas and Augustine gave us the Western "Just War" theory though other cultures had covered the idea earlier. Even Cardinal Wolsey's (and the Church's) thinking around perpetual peace was to allow fighting non-Christians. Kant and Bentham are hardly since time immemorial. I'll give you Jesus (only 2000 years), but the God of the Old Testament was rather pro-conflict, and other religions have very pro-conflict tenements. The accepted views of the majority of humanity until the late 20th century (perhaps not even now) is that different genders and races were unequal, that some were fit to rule over others, and that war was an inevitable consequence and participation in it was an honourable, noble and patriotic (once patriotism had emerged as a concept) activity. Who is not thinking this through. Plus the killing has massively reduced - the last decade has been one of the lowest for deaths in conflict in human history.
