No, there were only a relatively few Jews at most in the upper echelons of the Roosevelt Administration. The most prominent was Henry Morganthau, his Treasury Secretary. Morganthau raised the question of Nazi persecution of European Jews with Roosevelt, but Roosevelt for the most part deferred to his decidedly antisemitic State Department on such issues, confident that they would largely be neglected.
Roosevelt secretly boasted, BTW, that as a prominent Harvard alum, he was influential in in establishing a severe quota system which worked to discriminate against Jews applying for admission to his alma mater. He seems to have grown up in an antisemitic milieu, which included his mother.
It turns out that Herbert Hoover, throughout his long life, had a much better record on Jewish issues than did Roosevelt.
FDR did indeed have a fairly large number of Jews working for him, so much so the Jew-haters still refer to the “Jew Deal”.
Bernard Baruch was called the “Unofficial President”, and Jews like Ben Cohen, Felix Frankfurter, and Sam Rosenman were very close to FDR.
It also turns out that Teddy Roosevelt had a much better record on civil rights than did any of his Democrat successors until Kennedy.
Quite right. Morganthau kept after FDR regarding the Holocaust, who steadfastly refused to bomb the extermination camps. FDR also told a rabbi and a priest that the US was a Protestant nation, and that Jews and Catholics were here “by suffrance”. But hey, FDR did manage to open a second front against the Nazis in Europe merely nearly four years after the USSR was invaded and during which time the Wehrmacht was slowly ground down by the numerically superior Red Army. Oh, and before D-Day, launched a costly and destructive campaign in Italy, some of the toughest fighting of the war, at the insistence of Churchill, who wanted to avoid D-Day for as long as possible.
Why is that so hard.to understand? Like Stalin, FDR had an elite inner circle of Jewish collaborators doing terrible things, and the rest of the Jews were ignored.
