It’s neither of those things to presume that of the measureless casualties many had families and loved ones of their own, and those families and loved ones who lost their kin to the opposing faction in the war would want less than nothing to do with if not be outright hostile toward them, it’s just what any reasonable person would assume. And it’s reasonable because every body was once a child, and every child had to have come from somewhere; marriages, close friendships, battlefield trysts and so on. Presuming these wars had an appreciable number of casualties, enough to stoke either side to consider armistice, and given the number of conflicts that we’ve been through, the replacement rate must be almost as impressive, hence romance and hence more children, hence more heartbroken and likely ireful proles.
But if you want to dismiss it as headcanon go right ahead, no shot I’m going to be turning any deaf ears to reason here.
