Bet you didn’t think I’d do one of these comics ever again did ya
My own little take on that Soviet-German situation. Life is tough when you have virtually no political allies and your only friend Germany is starting to gain friends in the western world over the decade - I vaguely remember reading that the Soviet Union suggested a joint invasion of Poland several times(??) over the course of the 1920s in order to try and strengthen the ties between the USSR and Germany.
Nothing says friendship like a good invasion I guess!!!!
Although Germany was not quite recognizing the new eastern boarders, the Weimar Republic rejected the proposals.
