This article presents new evidence from the Russian Foreign Ministry archive regarding Josif Stalin's participation in the Tehran, Yalta, and Potsdam conferences. The article shows that the published Soviet records of these wartime summits are incomplete and inaccurate in a number of respects. These omissions and distortions were motivated by political considerations, and the correction of them facilitates a more complete rendition of Stalin's statements at the three conferences. Of particular importance is evidence that Stalin during the war strongly favored the dismemberment of Germany. Not until later did he begin to propagate the myth that he had always supported German unity.
