How did the geography of Poland affects its involvement in World War 2?

Poland's geography significantly influenced its involvement in World War II, as it is situated between Germany and the Soviet Union, making it a strategic battleground. The flat terrain allowed for rapid military movements, enabling the swift invasion by German forces in September 1939. Additionally, Poland's borders were vulnerable, leading to its occupation by both Nazi Germany and the Soviet Union as part of the Molotov-Ribbentrop Pact. This geographical positioning resulted in Poland being one of the first countries to experience the full impact of the war.
