Adocs, the Iranians are from Yaphet. Both anthropologically and linguistically they are related to the Europeans.
Dor, it could be that Eisav is not an ethnic group but an ideological group. Rav Chaim Brisker said this about Amalek. Really, it is very difficult to claim that the Europeans are literally descended from the Edomites. According to Kabbala Eisav is the perversion of din (kelipat hasmole) so any group that uses Law to oppress us would be Eisav (e.g. the Nazis ym”s who first made laws before taking official antisemitic measures). Yishmael is the perversion of chesed (kelipat hayamin) so any group that fights us by doing chesed with our enemies would be Yishmael.
