On the eve of the Second World War, the Soviet Union and the communist movement had reached their lowest point in terms of prestige, support and ideological influence. The chapter shows how a dramatic change took place during the war, and how ideological and political bases were consistent and durable at the start of the post-war era. The Nazi attack of 22 June 1941 had the immediate effect of radically changing the official language and image of the Soviet Union and the Comintern. G. D. H. Cole and Harold Laski had firmly criticized the Communist Party of Great Britain for its alignment to the Molotov-Ribbentrop Pact and its inclination to put British imperialism on a par with Nazi Germany. Soviet wartime myth-making was supposed to provide the proper synthesis of national appeal and class vision. Certainly, the prestige of Soviet Union had never been so high and, unlike the pre-war years, the communist movement had become powerful international factor.
