"Stalin went on to speak at some length of Germany. The Germans were a great and capable people with exceptional powers of organisation and great industrial strength. Moreover they were smarting from a sense of injury inflicted upon them by the terms of the Treaty of Versailles. We must expect that they would be actuated by motives of revenge. Stalin was perhaps more understanding of the German point of view than Litvinov, in the sense that he was less scrupulous and had no prejudice against the Nazis as such, which Litvinov no doubt felt for their treatment of the Jews... Stalin said that German diplomacy was generally clumsy, but maintained that the only way to meet the present situation was by some scheme of pacts. Germany must be made to realise that if she attacked any other nation she would have Europe against her. As an illustration he said: "We are six of us in this room; if Maisky chooses to go for any one of us, then we must fall on Maisky." He chuckled at the idea, Maisky grinned somewhat nervously. Stalin continued that only by this means would peace be preserved. The League as it was today was not strong enough for the purpose. It had suffered too many humiliations; even Paraguay had been able to flout it with impunity, he added with some exaggeration... It would be fatal to let events drift, since there was no time to lose if a check were to be placed on a potential aggressor. That should be in our power now, when actual war was probably some little time distant. At the last moment a check might fail."
