I understand that. My dad faught in the Pacific theatre, btw, so I completely get that. I'm talking about the general populace. My dad was in Nagasaki about 3 months after the bomb was dropped. He said that the general populace was very glad that the war was over.
The Japanese turned their culture into a business culture. They were able to transform into a modern society and turn that marshal philosophy towards enterprise. From what I see, the militent faction of Islam isn't interested in doing that.
And for the ones claiming the bomb wasn't necessary, it's really hard to say. An invasion of Japan would have been beyond brutal and would have been very costly in civilian and military lives. The only other alternative that I could have seen would have been a total blockade on the islands and starving them into submission. That's a horrible way to die too.
