In order to understand the USSR’s relations with foreign countries it is very important to analyze the decisionmaking of the Soviet leadership, especially in the Stalin period when all the decisions were taken exclusively by Stalin. The leader was certainly guided by the ideological purposes and the geopolitical interests of the USSR. However, an important impulse and the initial material for concrete decision-making was the incoming information. Academician A.O. Chubaryan notes that the information received by Soviet leaders (from diplomatic services, different representatives, fraternal communist parties, etc.) was not objective reflecting ideological stereotypes and formed doctrines. Such an orientated on the whole and intentional character of the information influenced the formation of a distorted picture of the world in minds of the Soviet leaders and thereby their decision-making.
