If it were not for Russia …
We hear: on September 1, 1939, Poland was invaded by the Germans, and on September 17, the Soviets “entered” eastern Poland. Meanwhile, this “encroachment” was also an act of aggression, with battles and crimes committed by this aggressor, which ended with the annexation of this part of the territory of the Republic of Poland. We are irritated when stories appear rom the German side that the aggressors were some nationally undefined “Nazis”. it is taken as obvious the that in the case of the second aggressor we were dealing only with some “Soviets”. We have also come across the opinion that the Soviets were a conglomerate of various ethnicities in which the Russians did not in fact play the main role. It is overlooked that these “other ethnicities” were  indeed Russified people, and therefore Russians; Stalin – himself a “Georgian” – was a Russian imperialist, the “Pole” Dzerzhinsky (DzierĹĽyĹ„ski in Polish) is still a model for the Russian,  and not Polish, secret services. The orders launched on September 17 for the “Soviet” troops, issued by Stalin (who is still revered by the Russians) were in Russian, and that language was used by the aggressor from the east.
On September 1, 1939, “brown” Germany invaded Poland, and on September 17, “red” Russia invaded Poland.
