Let me foment the discussion once again.

Sometime ago I red the book from Valentin Falin. If I understood him right, the Sovient view is:

- The USSR realized from the beginning that Hitler was a threat for their country and whole Europe
- The USSR tried to form an alliance of collective security for all nations, trying to contain Hitler's Germany
- The Western Democracies never accepted the USSR as an equal partner. All their proposals aimed a higher security for the Western countries at the prize of lower security for the SU. The west even tried to redirect German expansionism against the SU.
- When the SU finally realized that the concept of collective security for equal partners was not feasible, they tried to secure themselves, by installing a buffer between the SU and Germany.
- The part of Poland, that the SU occupied, was originally part of Belarus, which was occupied by the Poland illegally. The SU occupied it to protect the Russian population.
- The occupation of the Baltic States was similar to Churchill's plans to occupy Norway; a justify mean to contain German agression.
