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?
I remember in high school people made skits about American history after the AP US History test, as like an extra credit thing. One group's thesis was the Harry Truman "took the easy way out" by dropping the atom bomb, and so in their skit they had the staples "that was easy" button that he pushed to launch the nukes. And then they had an exploding bomb sound effect that followed the sound of the voice saying that was easy.
Holy shit that's like something DeLillo would write
