 The threat of an attack on Soviet Russia by Nazi Germany catalyzed the start of the Jewish Anti-Fascist Committee (JAC), a committee reaching out to Jews worldwide to support the Soviet war effort against Nazi Germany.Solomon Mikhoels, a Yiddish actor and director, headed the Committee.Other members of the committee were prominent Yiddish literary figures, actors, and doctors who wanted to help influence Jewish support for the Soviet Union through their writing and also using radio broadcasts from Russia to different countries.
