The Shah of Iran has cousins (first cousins) who are black as coal. Just happens that way. Check the Vahdat family who ruled Iran for a long time before the Pavlevi family.
They were much more typical of Iranians than Reza Shah's family ~ but NONE of these guys are blue-eyed blonds with cleft chins (except I notice that one of the great-great grand-daughters seems to be fairly blond, but I bet they picked that up here!).
Besides, I spoke of ETHNICITY, not just language, nor of light or dark features.
The Iranians and the Iraqis are and have been of the same ethnicity ever since they moved in over the Sumerians and swamped them in a sea of semi-brown.
There is rumor that the Hungarians used to worship the old Persian gods (well, so did the Roman soldiers, but still). But, going by your Persian features picture I would guess the Slavic areas might be a good example. Those features are very similar to the males in my family. Especially the forehead.
