The Great Patriotic War united the Soviet people in the face of the enemy, but with its completion, the socio-political situation in the country has changed. The victory of the USSR gave people hope for the liberalization of the regime and the weakening of strict control over many areas of life, but these expectations were not destined to come true.
Cooperation with the West in the fight against Nazi Germany allowed us to count on further expansion of contacts and cultural ties. In addition, after the end of the war, Soviet citizens who had been abroad returned to the USSR, who saw with their own eyes the life of capitalist states, so that stories about the "horrors" of the imperialist system and, in general, the propaganda of the ideas of socialism and communism no longer affected them, at least not to the extent and not by the same methods as this it was before the war.
At the same time, relations with the capitalist camp were heating up, the Cold War was beginning, and in order to maintain the state system, it was necessary to rally the population again, to create one common Soviet "nation". This state of affairs eventually led to a large-scale patriotic propaganda campaign in the country in 1947-1953, which remained in history under the name "campaign against cosmopolitanism".
