Thank you for the very well written write up. It reflects my exact thoughts on the dropping of the bombs, but laid out in a much more coherent manner.
Dropping the bombs was by all means a horror unleashed to stop an even greater horror from occuring. A trolley problem incarnate almost. Personally I think trying to moralize the bombs at all is reductive and ignores many of the facts of the situation and creates an idealized version of how wars are/where conducted that simply is not real.
