Russians were guilty of gross treachery during the recent negotiations, but Marshal Voroshilov's demand that the Russian armies, if they were allies of Poland, should occupy Vilnius and Lvov was a perfectly reasonable military demand. It was rejected by Poland, whose arguments, despite their naturalness, cannot be considered satisfactory in the light of current events. As a result, Russia took up the same positions as an enemy of Poland that it might have taken as a very dubious and suspected friend. The difference is actually not as great as it might seem. The Russians mobilized a very large force and showed that they were able to move quickly and far from their pre-war positions. They now border on Germany, and the latter is completely unable to expose the Eastern front. A large German army will have to be left behind to monitor it. As far as I know, General Hamelin estimates its strength at least 20 divisions, but there may well be 25 or even more. Therefore, the Eastern front potentially exists.
Russia is pursuing a cold policy of its own interests. We would prefer that the Russian armies stand in their present positions as friends and allies of Poland, rather than as invaders. But to protect Russia from the Nazi threat, it was clearly necessary that Russian armies should stand on this line. In any case, this line exists and, consequently, the Eastern front has been created, which Nazi Germany will not dare to attack...
