This probably is an appropriate time to Godwin the discussion and point out a certain Austrian/German leader's very different ideas were also shaped by his negative experiences of a world war. Veterans react differently even to similar experiences and cover the full range of positions on war from gung ho militarism to unapologetic pacifism. Perhaps military experience lends them a more informed perspective on what the realistic outcomes of a war might look like, but it's no inoculation against militarism.
