The real moral dilemma, in my eyes, is whether the use of the nukes was necessary in the atmosphere directly before the Cold War. Many historians have argued that Soviet Russia cooled relations and started the Cold War due to perceived hostile acts from the West; whether that is hogwash or not, it is an interesting question whether or not it was necessary to kill all those Nips just to show Russia that this is the shape of things to come. The Allies had already committed to mass murder in the name of freedom, so one technique over another is somewhat irrelevant; the geo-political climate that came after is the true heritage of the atom bomb.
It was discussed in the days before the bombing of Japan whether it'd be sufficient to simply stage a show-bombing of a deserted island, in view of diplomats from Nippon, Russia and so on. The political climate of the War didn't allow for that, but it's an interesting dilemma nonetheless. Certainly Stalin didn't care one whit about the dead Nips, the display of force (of which he was cognizant beforehand) was what pushed the Soviets into the arms race.
