You seem to want me to rehash my position (also asserting "it's not that complicated") when it's obvious it is complicated (otherwise people wouldn't hold disagreements so strongly, even here) and also you could simply read about my position or other's in this very comments section of HN.
The fact you mistook the position under discussion to be about Japanese crimes (which is why you so vehemently described them), when it was about alleged justifications for the atomic bombings, also makes me think it's indeed a complicated topic.
What I am telling you is that I am not going to rehash my position again for your benefit. Read it elsewhere in this comments section. If you feel like you must simply restate what others have already said, maybe don't? It adds nothing to the conversation.
I'm well aware of the literature on the subject. A non-exhaustive list of various books on the various positions is available in this handy thread:
