I think Stalin did go after Jews for being Jews...see the Doctors Plot.....he pretty much blamed most Jewish party members by name for being Bolshie rivals and Trotskyites
This rivalry between Jewish revolutionaries started with their preponderance with Menshies and then Lenin’s cliques and later Trotsky
And Stalin and Beria....Molotov too I guess even though his Jewish wife was imprisoned....all blamed Jewish commies as Jews of a conspiracy against the state....some party member Jews survived but likely renounced anything to do with the religion of their birth
They purged most of them as such...
Russian fellow commies turned on them
Then Fascists blamed them as communists even as commies purged them via that special Stalin disappearing photo technique
It was a severe double whammy for continental Jewry....ironically the Iberian peninsula..... fascist too....was even though not totally innocent....a rare refuge for Jews.....not sure Franco’s reasons for resisting Nazis calls for railcars
Cronos you meant Trotsky
The Doctors’ Plot was 52/53, by which time Stalin had been in absolute power for over 25 years. It seems fairly obvious therefore that Jews, as such, were not a top priority of his.
He was perfectly willing to scapegoat Jews, if convenient, just as he had targeted tens of millions before them, but by 52 he was running out of other groups to aim popular anger at.
One of Hitler’s first acts on taking control was to start isolating Jews from society, Stalin didn’t start remotely similar action for 25 years. I don’t think the anti-semitism is comparable.
