We used to be friends with Iran and many of the people are pro-American. Not counting the crazies in charge of course.
Not an exact parallel, but we have a large contingent of anti-communist Cubans in America. Ted Cruz and Marco Rubio come from such families.
Likewise we do have a large number of Iranians that came here during the Shah's regime, and more that got out later, after the mullahs took charge.
Finally I have met Iranians that were Jews, Christians, Bahai and even Zoroastrian. Yes muslims, too. My wife has worked with Iranian women, that don't wear headgear here. When they go back to Iran they wear headgear, to avoid trouble so they can visit their families.
