Let me go through point by point
1) There was no reason to bomb the two cities previously as they do not have war industry there. The bomb there was for a lack of a better word, a terror weapon, that is used to strike fear
2) After the first bomb, the war ministry contemplated it. However, they would want to retain their military machines,etc. Furthermore, there was strong resistance to it. The second bomb sealed the fact. Like singscott said, there was even a coup to prevent the Emperor to tell the people.
3) It IS a known fact. The links I had previously posted had the facts there.
4) Although the military was reluctant to use it, they only asked Eisenhower, not MacArthur. Read the links I had provided previously instead of books, they are more exhaustive and in my view, balance.
