Against the standard position that Stalin saw enemies all around him and was seeking world conquest, it is worth recalling comments like these. This is from 1947, in response to an interview question:
Let us not mutually criticize our systems. Everyone has the right to follow the system he wants to maintain. Which one is better will be said by history. We should respect the systems chosen by the people, and whether the system is good or bad is the business of the American people. To co-operate, one does not need the same systems. One should respect the other system when approved by the people. Only on this basis can we secure co-operation. Only, if we criticize, it will lead us too far.
As for Marx and Engels, they were unable to foresee what would happen forty years after their death. But we should adhere to mutual respect of people. Some people call the Soviet system totalitarian. Our people call the American system monopoly capitalism. If we start calling each other names with the words monopolist and totalitarian, it will lead to no co-operation.
We must start from the historical fact that there are two systems approved by the people. Only on that basis is co-operation possible. If we distract each other with criticism, that is propaganda.
As to propaganda, I am not a propagandist but a business-like man. We should not be sectarian. When the people wish to change the systems they will do so. When we met with Roosevelt to discuss the questions of war, we did not call each other names. We established co-operation and succeeded in defeating the enemy. (Works, vol. 16, p. 111)
