I sincerely hope you're just being a trolliollio, because humans are champs at finding the flimsiest justifications for going to war, and let's not forget the time the Vatican was all "Hey, see those fuckers South of the Mediterranean? Go send our Jock-Knights to go collect their heads and take back some city that was mentioned in the Bible a few times, a'right? Pope OUT!" Because that was a thing.

Or when the Incas were all, "Oh shit, our God's having his time of the month. Better go invade and enslave that neighbouring city because we're waaay below quota for getting the sun to come up next week."

Or when Joan of Arc was waking up from a hangover, stumbled out and was like, "Guys, guys! God just fuckin' told me, 'Fuck the English, amirite?' in those exact words, and he said I had bigger balls than the rest of you, so I'm totally in charge."

And so on. Point is, the state and church being bed buddies hasn't boded well for preventing wars anymore than kicking the Church to the curb like the USSR and China, 'cause if you don't fear God, you don't really care that you've got enough corpse-bones to remake the cities that were destroyed in whatever war you were apart of.
