That may have been appropriate in a general anthology of Soviet Yiddish but the book was based around the fate of the Soviet Jewish Anti-Fascist Committee (JAFC) members. Burg was not involved and Beyderman was born a year after the JAFC was closed down.
Karl also wrote: "Yiddish still survives and indeed it flourishes, even in the former Soviet Union." I wish that were the case.
