> Japanese civilians at the time weren't really innocent. The whole country was working for the war effort, mainly to kill other Asian people.

Wow, this is sounding terrifyingly similar to how suicide bombers justify their targeting of civilians. It's sad to see how easy it is for people who didn't grow up under the dogma of fundamentalist religion can still come to this way of thinking.

My friend, I implore you to think really hard about what you said, and take the time to recalibrate your moral compass. I can only hope that at some point in the future, you'll come to think that, war or not, enemy or not, killing civilians is bad. There is no shade of grey. It's only bad.
