Here a part of the conclusion for reference:
The Bomb was the perfect excuse for having lost the war. No need to apportion blame; no court of inquiry need be held. Japan's leaders were able to claim they had done their best. So, at the most general level the Bomb served to deflect blame from Japan's leaders.
But attributing Japan's defeat to the Bomb also served three other specific political purposes. First, it helped to preserve the legitimacy of the emperor. If the war was lost not because of mistakes but because of the enemy's unexpected miracle weapon, then the institution of the emperor might continue to find support within Japan.
Second, it appealed to international sympathy. Japan had waged war aggressively, and with particular brutality toward conquered peoples. Its behavior was likely to be condemned by other nations. Being able to recast Japan as a victimized nation — one that had been unfairly bombed with a cruel and horrifying instrument of war — would help to offset some of the morally repugnant things Japan's military had done. Drawing attention to the atomic bombings helped to paint Japan in a more sympathetic light and deflect support for harsh punishment.
I always thought that, I remember a long time ago I went to see a Japanese movie, I think it was "
Kuroi ame" in a movie theater in Europe, at the beginning they talk about the bombing or you can see Americans troop, I don't quite remember but the people start to shoot
"Ouh ! Ouh ! Ouh !", I was quite surprised because I never seen reaction like this in a movie theater in Europe, also that denote some anti-Americans feeling and that was the first time I witness that.
Also I was with a Japanese girl in Australia around the Hiroshima bombing anniversary, we were walking on the streets and quite a few people came to her to shake her hands and excuse themselves for the bombing, honestly I did not get it, for once they are not Americans and the girl knew nothing about the war, actually I told her that was so weird and she told me that was okay and that she liked it. This World is crazy !
Looking back at it now it was probably an early occurrence of "We white men did really bad things to all you minority people around the world for centuries and centuries and are really sorry for that, can you ever forget us ?", that's the only way I can explain this.
I have been to Hiroshima, to the park, to the museum, it is a very moving place, but yes, I feel the Japanese think they were victims and they did nothing bad and a lot of people in the World thinks so too nowadays, except for Chinese and Koreans, so possibly those bombs were the best thing that could happen to Japan at that time.
