no, you can't get a tl;dr. this is a real world conflict with real world details. yes, based on the availiable evidence and the sequence of decisions and informations the things you likely believe about nuking japan are retroactive continuity by cowards and liars. it's a significant part of a world-spanning conflict, of course there's many things to talk about and understand before you can have any sort of insight on judgements of it. watch it some time, if you can, i highly reccommend it. it sheds light on the idea of "morale bombing" in general. contemporarioly it also really puts into perspective just how pathetic russias conduct here is; of course israeli conduct too since the lesson is the same as it ever was.
