What if FDR had lived around a year longer than OTL?
I can see some potential effects and discussions already -
* USA softer on the Soviets at the immediate end of the war
* USA more sympathetic to Attlee's Britain
And another thing - would FDR have used the Bomb on Japan? I think the answer is probably yes, but it changes the dynamic of the Cold War if the decision to use it is associated with FDR, who dies not long afterwards, rather than with Truman who gets himself elected in his own right.
