Iran of course is Shiite, while the bulk of the Arabs are Sunni, that is a problem or could be a problem. Also, there is the simple fact that Iran is non-Arab and most of the Muslims in the Middle East are Arab.

Many of the most difficult questions concerning the role of ethnic minorities centers on language.

The United States has been an immigrant country. The Hispanics who come here are largely from Mexico and South America. They are Catholics, but that is an American religion. One-third of our population is Catholic so that does not have the same impact as Muslims coming into Europe.
