The US war aims in Europe had nothing to do with the Jews, whether they were saved or weren’t was a matter of indifference to the administration, and to accuse FDR of failing to do something that he had no responsibility for and no interest in is extreme post hoc argumentation.
And the direct quotes from FDR in the article are therefore also irrelevant?
The article's primary charges against FDR relate to his personal antisemitism. I don't see what that has to do with US war aims in Europe. Particularly since most of the examples occur at a time when the US was not at war. The criticism that FDR could have pressured Churchill to allow Jews to settle in Israel as required by the Mandate is legitimate. But too much trouble for FDR. The article does mention FDR's support of antisemitic Vichy policies in Morocco, policies rejected by the Sultan. But that's not Europe,
If you wanted to discuss wartime Europe I could bring up brave Poles like Jan Karski and the Polish government in London who warned FDR and numerous US officials about the concentration and death camps. To no avail. That was wartime Europe. But not purely antisemitism. They were killing Christians too. And though Karski's warnings related primarily to Jews, his and the Polish government's appeal rested on their status as Polish citizens.
Your rejection of FDR's antisemitism fails.
