I have read Mein Kampf and don’t remember that. But translations vary. A translation made for Middle Eastern readers might say that.
As I understand it, the word "Iran" is Farsi for "Aryan".
Before WWII, Iran was known as Persia.
I don't know exactly when the name change came but it seems to me like it was sometime during Hitler's reign.
Under Obama/Clinton/Kerry, the State Dept. and Justice Dept. would released “translated” transcripts when Islamist jihadists in America make threats and kill. You’ll notice those transcripts translate “Allah” into “God” and sometimes they will just bluff and indicate “foreign expression”.
