Who did hitler blame for Germany's problems

Hitler often blamed Jews and communists for Germany's problems. He mainly expressed this in his Mein Kampf.

Hitler felt betrayed by Germany's leaders whom he believed had surrendered when victory was still possible.

However he primarily blamed the Jews particularly Jewish bankers and financiers who he saw as seeking to profit from the war. He also saw a strong link between Bolshevism and the Jewish community which he interpreted as further proof of where the origins of conflict lay.
