On the one hand, he was extremely dedicated to achieving unconditional surrender. On the other hand, he was more willing to work with Stalin (afaik) than Truman, and Byrnes would never have become Secretary of State. Would FDR living to the end of WW2 have changed the outcome of the war with Japan?
...and then they didn't remove the emperor from power.
and they were never going to remove the emperor from power. Most of the military leadership supported leaving the emperor in place. Afaik, there was never any real chance of the emperor being removed from power, at least by the US (could be wrong on that though). Just an insane push for unconditional surrender by Truman and Byrnes. Truly :amerikkka:
