after starting a warr, and losing it, hirohito offered to "surrender" but only if he got to keep all the territory his forces had taken, and he got to keep dong whatever he liked.
it doesnt work that way.
eventually, hirohito kept his titular position as "emperor" but lost all his real authority and japan became an occupied nation, which was a concession by the us AFTER blowing the shit out of nagasaki and hiroshima with nukes. before that hirohito offered only talk.
talk doesnt end the fight, tapping out, going limp or crying uncle does.
japan kept putting their dukes up, so they kept getting stomped.
the nukes puke the cherry on top, sure, and that gives you bad Feels, but the OTHER options were, to continue blasting japan with The LeMay Treatment (google it) or launching amphibious invasions on each island, which would have killed far more people than the nukes did, before hirohito would finally accept the inevitable.
if somebody suckerpunches me, they are gonna get stomped, and the stomping will continue untill they SURRENDER.
just because i now have the upper hand in a fight i didnt start does not transform me into the "aggressor" so you can shove that nonsense right back up your fundament.
I'll kill a man in a fair fight...
or if I think he's gonna start a fair fight...
or if he bothers me, or if there's a woman...
or if I'm getting paid.
