No, Iranians are Persians.
During World War Two, Persia changed her name to the Farsi word for Aryan in an effort to persuade Hitler to allow her into the Axis alliance. In Farsi, Aryan = "Iran".
But Persians are a different race from Arabs, and would take great offense to being lumped into their ethnicity. Arabs are not considered pure of blood, after all. Arabs are not the Master Race, and Persians think that they are that master race...
