Of course not, he could not be objective.
I hate when people use that argument.
Well the fact is that atom bomb was aimed at civilians so where is the courage here? it was barbaric act and can't be excused.
But the view that you would share is that no-one should have to go through the same experience, and since 1945 no-one has.
I hope you are talking about atom bomb and not other atrocities that were committed against humanity by megalomaniac leaders all over the world.
