Did you read the first link? Stalin especially disliked Jews and used euphemisms to target them domestically for placement into gulags. Yes the Soviet Union’s military might, manpower and resolve were critical to stopping the Nazi menace. Credit where credit is due.

But there were several dynamics that led to Jews being persecuted (obviously less severely than they would have been under Nazi rule) in the USSR pre and post war and especially post war under Stalin. The wiki article does a good job of describing those dynamics.
