The Soviet leader Stalin was accused for betrayal of the October Revolution and the sociopolitical work of his regime, especially the secret police NKVD, was compared with the ones organized by German Nazi leader Adolf Hitler and the Italian Fascism leader Benito Mussolini, who at this time made active political struggle against Communism in their countries and were both ideological and political enemies of the Soviet Union. In making the opposition against Stalinism, the leaflet had made use of purely socialist ideas. In particular, it had used as the title the communist ideological slogan "Workers of the world, unite" borrowed from The Communist Manifesto by Karl Marx and Friedrich Engels which laid the ideological foundations of Stalin's All-Union Communist Party (bolsheviks).
