in Oliver Stone's *The Untold History of the United States,* Stone makes a claim that the Japanese were trying to surrender, but this information was hidden from Truman so that the generals could test the bomb. Is this true? what evidence supports this?

/u/restricteddata answered a similar question about five years ago. The short version is that some members of the Japanese government were in favor of a conditional surrender, but not an unconditional surrender. Unfortunately, they didn't go into whether or not Truman was informed, hopefully somebody can shed some light on that as well.
