Hitler Settled on Acquiring German Lebensraum in the East in Russian

Hitler settled on acquiring German Lebensraum in the east in Russian territory in part because of his racist belief that

A) the Slavs were an "inferior" people now governed by impotent Jews among the Bolsheviks and worthy of enslavement.
B) the weakened Aryan "race" could only be rejuvenated and made better through war against the ancient enemies of the Fatherland.
C) the Anglo-Saxons were a decadent race and would never come to the aid of eastern Europeans.
D) Germany must conquer all of Europe before the great American race dominated the globe.
E) there would be no opposition to the German takeover of Russian territory, as the inferior Slavs would eagerly welcome their racial superiors.
