To go further down the rabbit hole, there were only two ways the US would have lost the war against Imperial Japan, and the second was Soviet subversion after the war in Europe was finished and we were not only not needed by them, but actively unwanted as a fully mobilized Great Power. Then again, as I mentioned above, we were rapidly transferring divisions wholesale for redeployment in the Pacific for Operation Downfall. What I'd really like to know is when the Bring the Boys Back Home propaganda campaign began, before or after VJ Day; my Google Fu isn't good enough right now. The other way, of course, would be the Japanese scheme to make us tire of cost in blood, and their Air Force and Navy had a truly unpleasant surprise in store for the US Navy with vastly more kamikazes ready than we thought, which would have been much more effective than in Okinawa due to the vastly shorter distances and navigational skills required. That was, BTW, the bloodiest US Navy battle in history. So underestimated that half our carrier air assets were assigned to the north of the relevant area, and the planned CAPs were way to thin to have stopped all that many of them. Although we could have at least somewhat corrected those in a few days after the magnitude of the kamikaze threat materialized, but there's no guarantee of success on our part, and if the Japanese had managed, as they planned, to take out troop transports.... On the other hand, we were really angry by then, and fighting to win. Is there any indication that they thought the outcome in the Pacific was in doubt? (Serious question, I don't know.)
