The word "Persian" in this case, ought to be used very carefully. Most of the high ranking officials in the Islamic Republic of Iran (IRI) are NOT Persians or of ethnic Persian origins. Iran has many varied ethnic groups - has been the case for centuries.
Acutally, the Baseeji militia, under the control of the Islamic Revolutionary Guard Corps, in Iran, are mainly of Arab/Palestinian origins.
