History has tended to whitewash FDR's role in forcing millions of people into Communist subjugation, which was worse than Nazi tyranny (at least it killed a lot more people.)
Yalta effectively ratified the imperialist borders agreed to in the Stalin-Hitler Pact, with the support of FDR.
It was also after the Yalta agreement that the system of gulags really got going. We agreed to send Soviet POWs we rescued from the Nazis directly to Siberia.
This is a shameful chapter, and I am glad to see President Bush have the courage to say so. It's about time someone in a position like his did this.

This is all what my grandfather (died in 1986 one month short of 100) always said. He despised FDR and had little doubt that FDR prolonged the depression with his policies and that he sold out eastern Europe, generating the cold war. He was from Missouri and bore a resemblance to Truman. I remarked on that once as a kid and my mom told me in no uncertain terms to never repeat that to grandpa. He disliked Truman, FDR and all democrats. He considered them the party of corruption and the party of the KKK. He saw it all first hand and I'd say he had it right.
