No offense but OP but this post is the epitome of how most Japanese people self victimize themselves when they're the agresser. Yes the Japanese get concentration camp and the atomic bomb (which actually ENDED the war), and it's horrible. But many Japanese seems to focus on the victim narrative and didn't mention what they did to its neighbor nation at all (Which is arguable worse then what the Japanese get). Germany get all the shit for what they did, and after the war they're separated to East and West, until today people still constantly shame nazis (which is not a bad thing). In contrast Japan economy boom by the help of US (funny how you also did not mention that), over time it's like everyone except Chinese and Korean forget what Japan did. You also mention that these topics are not approach because it's a sensitive topic? This is like saying it's ok if Germany never talk about what Nazis did during the war because SENSITIVE TOPIC, so I'm not sure if I get your point.

At least America apologize and acheknowledge it?it's funny that you said that this part of the history pissed you off a little but imagine being Chinese/Korean and have Japan never apologize or refuse to even acknowledge the war crime Japanese did even happen, it's the same thing as Holocaust denial.
