Makes one wonder just how many of the Leaders are Iranian? The gran ayatollah brought in many foreign ayatollahs into Iran with him and placed them in positions of power. Mr Jimmah Caater was the gran a$$hole that let it all happen.
Unfortunately, they are mostly Iranian Ayatollahs, though All ayatollahs, mullahs, and their supporters, primarily, subscribe to Arabic ideology, traditions, customs, and so on... when deemed required they incorporate Iranian ones.
P.S. - personally, I don’t buy the stuff about being born in some place/country as a pre-requisite. An example, being born in a stable does not make one a horse.
