It sounds like the point you're making is that Japan's brutality towards Korea justifies the bombings. Without arguing whether or not the bombing was justified, surely we can feel empathy for the HUMAN BEINGS injured or killed, particularly given that many of them had nothing to do with the war and merely had the bad luck of being born into that city and country at that time? This does not mitigate or excuse the violence inflicted by the Japanese, but merely acknowledges the value of human life.

Our history is full of brutality; to trot out a well-worn Gandhi quote, "An eye for an eye makes the whole world blind."
