E1b1b is not necessarily North African. It is actually European as well. Nobody is quite sure were it originated from. Only current theories. The oldest mtdna U6 (that is often found correlated in E1b populations) ever found was surprisingly found in Romania fairly recently.
North Africans were originally white people too.
Adolf Hitler was just a typical Austrian with an older-than-average Western/Central Europe paternal ancestor. Does not make him (Hitler) any less European. (there are even Sub-Saharan Africans that have their share of R1b clades, such as V88. (But these individuals have yet to have proven, no fair skinned ancestry.) Meaning Hitler's original ancient European paternal father, in all likelihood, was NOT originally an Indo-European (Aryan) speaker.
But, Hitler may have been saddened to know, if technology was available in that time, that the haplogroup most common among the Aryans is R1a. (A haplogroup which his Polish and Russian neighbors, or enemies, carried in abundance.)
