If you prefer some other moral standard, go right ahead. You'll know what you're rejecting.
You are simply obfuscating the facts. As my last post stated, nearly all Japanese citizens were considered combatants by their own government. Furthermore, both Hiroshima and Nagasaki were military targets.
What you are actually arguing is that WWII could not be fought by the US at all, since all air raids more or less indiscriminately hit both combatants and civilians whether the bombs were chemical or atomic.
