1. It was the only option at the time as it saved who knows how many lives of allied soldiers. I think this is proven since Japan's rulers did not immediately surrender after the first bomb. That idea of being unable to surrender was demonstrated after the first bomb when everyone knew how massive the devastation was.
2. Those arguing on moral grounds must realize war in itself isn't moral and innocents die regardless. Therefore the choice in this was us or them and the US military chose them (to die) for obvious reasons.
3. Keep in mind that Japan is the reason US even entered the war.
