Ping. Interesting that the article doesn't bring up the fact that the regime 'themselves' are 'Arabic' in culture, even though they're Persians they embrace an Arabic ideology, culture, mentality instead of a Persian one.
I must disagree with your conclusion that the Iranian leadership is Arabic in culture. The official language of Iran is Persian and they do not consider themselves to be Arabs. Islam is obviously an Arabic influence, but the Persians distinguish themselves from Arabs just like the Turks and other non-Muslim Arabs. Iran has strained relations with Saudi Arabia and other Arab governments in the region. The Iranians are certainly Islamic fanatics, but they are Persian Islamic fanatics.
"they embrace an Arabic ideology, culture, mentality instead of a Persian one."
Islam is not an "Arabic ideology." At least not any more than Christianity is a "Hebrew ideology" or Buddhism is an "Indian ideology".
Arab is an ethnic group like Persian is... both are mostly Muslims and have the same culture(religion more than history or race defines culture...even in a more secular west). And didn't Mohammad begin his campaign by killing and terrorizing Arabs themselves? And a lot of so called Arabs aren't Arabs by ethnicity, but Arab by language and culture.
