There's no way that guy is a real Iraqi. He clearly is the descendant of an English or French soldier and his grandmother hid the affair or something. I hope I don't offend anyone in his religious order, but this guy's grandfather is not who he thinks he is.
Unless you accidentally linked the wrong image. Or perhaps he has a rare skin condition? Being part-albino or something?
Galifianakis is half Scottish. That's where the red hair probably comes from. For Stassinopoulou I would agree with the ones saying that she bleaches her hair.
Also: Thracians count as Greeks? I think we don't consider the ancient people that inhabited Thrace and eastern Balkans and Black Sea as Greeks but they eventually mixed with us (And the Huns, the Romans, the Mongols etc around the Black Sea). We don't consider Pomaks as Greeks either.
However, I am not very well versed in Anthropogeography or who counts as what.
