Both schools of thought, however, assume that the bombing of Hiroshima and Nagasaki with new, more powerful weapons did coerce Japan into surrendering on August 9. They fail to question the utility of the bombing in the first place -- to ask, in essence, did it work? The orthodox view is that, yes, of course, it worked.

The support for this narrative runs deep. But there are three major problems with it, and, taken together, they significantly undermine the traditional interpretation of the Japanese surrender.
