Ironically, Hitler in the early 30s offered Pilsudski an opportunity to reclaim Soviet lands for Poland if he aligned with Hitler against Russia, knowing of Pilsudski’s hatred of the Russians, but Pilsudski, wisely did not trust Hitler enough to take the deal.
Pilsudski’s 1934 non-aggression pact between Poland and Germany, which Poland negotiated against the wishes of France and Britain, did a lot to secure Hitler’s position in Germany, as well as weaken the League of Nations.
