Diary of the Plenipotentiary Representative of the USSR to the Great Britain I.M. Maisky

December 21, 1939
Secret

The severity of the anti-Soviet wave seems to be starting to subside somewhat. There are two main reasons:
1. The firm and decisive position of the Soviet government finally convinced the British government that no matter how noisy Mannerheim and Co., the question of Finland is essentially resolved. What is the point for the British [government] in this case in vain to wave their fists and, not being able to "save" Finland, only to spoil their relations with the USSR even more? Of course, it will send weapons, airplanes, etc. to Finland (although not in very large numbers), but perhaps it will not want to bring the matter to an open break
2. The Geneva farce of the "anti-Comintern bloc" made a rather strong impression on many "leftists", and they begin to scratch their heads. In addition, of course, newspapers cannot stand the three-week "sensation." We must look for some new tricks.
Unless something unexpected happens, the current wave will gradually die away. However, it would be a big mistake to think that Anglo-Soviet relations after that would return at least to the - not very satisfactory - level at which they were in October - November. On the contrary, my general impression is that if in the near future no new factors come into play (from the English or ours, or from both sides), then we have a period of further deterioration of these relations, possibly even a break .
