This isn’t really new, but some of the most interesting material comes from Rafael Medoff’s demonstration of how the material was buried and misreported by historians sympathetic to liberal presidents. When FDR endorsed quotas for Jews in the US and even North Africa, liberal historians claimed that he was being “practical” or actually trying to help Jews. And then there’s the story of the efforts to bury and lie about FDR’s exchange with Stalin about the Jews.
