Let me add another layer to this, as well…the casualties in both attacks totaled a bit under 200,000. This happened in the space of a few seconds. By comparison, Operation Meetinghouse, or the bombing of Tokyo, did similar numbers of casualties and property damage over the space of the night of 9 March 1945. Which is worse…a bright double flash and done, or being burned to death by M-69 fuel-air bombs?
Put it in a more personal way: Would you rather be shot dead quickly, or slowly beaten to death?
