While I hate to disagree with you on such an important subject, my guide to this is:
FDR and the Jews (2013) Richard Breiteman
Breitman's thesis is that Roosevelt cared more, and did more than is usually recognized these days.
That’s a good reference. And I have done extensive reading of similar sources. FDR was very accomodating. He truly cared about America. I don’t think he was as intelligent as Reagan or Cruz, but he had no plan to bring this country down. He was at worst disillusioned.
The problem is that the real history, the motivations and sentiments of the people at the time are constantly being attacked by the Left. It is never-ending and historians and commentators have a responsibility to rebut these American hating leftists.
I’ve even heard and read from several leftists that FDR was a ‘Holocaust Denier’. There’s just no end to their insanity.
Paul Johnson, whom I respect greatly as a historian, says Israel never would have happened under FDR.
