"The spectre of the holocaust and anti-Hitler propaganda probably did the job. That and the powerful unconscious desire to believe it wasn’t all worthless."

In Roosevelt's mind there was only one enemy really worth troubling over, and that was Nazi Germany. FDR was totally focused on defeating Germany, and everything he did was for that effect. To accomplish this he made close personal friends with Churchill and became a loyal ally of Stalin.

Roosevelt either didn't know, or chose not to see that Stalin had been just as brutal as Hitler.

But brutality was not Roosevelt's standard for making allies. Opposition to Nazi Germany was.

Yes. I would believe that it would be useful to refer to FDR's Fireside Chat #19 (I think it's 19), which was given after Pearl Harbor but before the Germans declared war on the US.

In it, FDR pretty much laid the blame for Pearl Harbor at the feet of the Germans, accusing them if not of actually orchestrating the attack then at least significant collusion in it.
