The Nanking massacre is only one of thousands of equally appalling events that the Japanese were responsible for. You're right Wings most people, especially the little crowd of weaboos out there, have no idea whatsoever what went on during the Japanese invasion and occupation of Asia. No idea how many people they killed and the incredible suffering they created for those they didn't.
I'm not trying to make out the atomic bombs weren't horrific. Of course they were. But I think it's very hard to say that the bombs were unjustifiable. The allied powers had already lost millions of men in the war in Europe and Asia. The prospect of a protracted war up through onto the Japanese mainland would have been somewhat horrifying and incredibly bloody. Hard to say what any of us would have decided to do when offered a possible solution that would save 100's of thousands of lives of the soldiers we were responsible for.
The fact that a second bomb needed to be dropped says more to me about the ridiculous leadership the Japanese people had to endure during that dark period than anything about how terrible the Americans were.
