Opinion of the atomic bombings of Japan

[kikka]

Why USA didn't drop an atomic bomb on Tokyo is that they wanted accurate experimental results of atomic bombs.At that time Tokyo was greatly destroyed by many air attacks while Hiroshima wasn't. Since Hiroshima had been never bombed before the atomic bomb,damages by atomic bombs were very clear. Hardly had the war ended when they sent an investigating commission (not doctors) to Hiroshima to investigate atomic bomb victims.
Japan was astonished by invasion by Soviet Union rather than atomic bombs, I think. This is because Japan wanted Soviet Union  to mediate between Japan and allies.
