SIN, I spent a few years in Japan, and this was my interest at the time. The Japanese military was defeated for the most part, but the citizens were preparing for an invasion (apparently, their blind allegiance to the emperor had something to do with it). They had stockpiled munitions, caves dug all over the islands to prepare for the civilian citizenry to resist the invasion of the homeland. Picture little old grandmothers with pitchforks, and most willing to sacrifice themselves. The estimate bandied about in the history books was that it would cost about 100,000 American lives to take the islands. Civilian casualties probably in the millions. It was decided to "convince" the emperor to surrender. And the cities hit were valid military targets.
Oh my, what if it were a runoff between Rosie and Hillary? Can you pick C) none of the above?
