'Nor nit geklogt' (Just don't lament) is a Yiddish adaption of the famous communist 'International', written by an unknown author in the Kovno ghetto. Many considered the Red Army to be their best prospect for liberation, and so support for the Soviets was strong. The lyrics clearly allude to the Nazis but do not mention them directly, and encourage Jews to be hopeful and defiant.
