Oh yes, we even have streets named after FDR in Poland which you might find amusing. He sure gained all the applause from the post-market crash recovery in the 30s. This being said, Yalta Conference was his worst moment, he struck down British Empire but laid a foundation for the Iron Curtain.
PS. If FDR was still alive in the summer of 1945 I'd say you don't drop the nuclear bomb on Hiroshima. That was Truman's no-nonsence hardball. The biggest what if for me is what if Truman was there in Yalta rather than FDR. He'd probably see through Stalin's bullshit one way or another.
Okay, history lecture over!
