so I am starting this thread to discuss what could be the possible reasons for Nazi Germany defeat in WW2. Members are free to give their opinion or points which they think cause the final downfall of the third Reich or sealed it's fate. there could be no. of reasons --- which can be further elaborated. anyone can add more points if they want. • invasion of Soviet Union. • germany underestimation of Soviet reserve's. • incompetency of Hitler & German higher command. • not investing in navy. • declaring war on US. • operation Uranus( destruction of 6th army). •Bagration ( destruction of army group center). • lack of oil. In my personal opinion it's was moving Guderian 2nd panzer south for encirclement of Kiev which sealed Wehrmacht fate as it delayed offensive on Moscow & it's captured before winter. anyone watching this thread. You are free to add your opinion or points you think were responsible for German defeat.
