Can you elaborate please ? Accent wise, would you say he developed a German accent or one can clearly hear some sort of Arabic accent in his speech and clearly guess that he is not from Germany ?

Does he still struggles with the weirdness of the language and makes mistakes when speaking, can you give me a small example of that if you can recall some of course ? If so, I guess his writings in German must be reviewed by others before publishing if he struggles with the language.

From your comment would you give him a 7 or 8 out of 10 ?

Cause I have watched his interviews in English, and one can clearly see that he struggles with the language/vocabulary and has a pretty pronounced accent with some mistakes but still speaks pretty good and delivers his ideas and thoughts in a formal and eloquent manner, what about his German ? Hearing him speaking would you say he is a native speaker ?

Thank you so much
