Because if Japan was invaded, prefecture to prefecture, city to city, up to 1,000,000 Americans, 500,000 Russians, 50,000 Australian, 35,000 Canadians, and 100,000 British men were projected as casualties, in addition to over 6–9,000,000 Japanese.
Hirohito and his generals made the call there, had they surrendered, the bombs would never have been dropped, had the bombs never been dropped, no Hiroshima/Nagasaki. No Hiroshima/Nagasaki, no debate. If an invasion..Kamikazi’s all throughout Japan…men, women, and children encouraged to be ‘human bombs’... would have made Iraq seem like a playground…
