This fact scares the crap out of me.
It sure does seem like a lot but remember many of them first came over when the Shaw fell. They've sinced raised families. The children are for the most part fully westernized and educated. I've met quite a few myself and the Iranians hold no worries for me. None of the ones I've met have been particularly religious. Very secular.
I even feel we owe them something for the Shaw fiasco and the hell the mullahs have been.
This is a little weird for me usually I'm out there with the kill all the muslims crowd, ra ra sis boom ba nuke em till they glow. But I feel quite a bit different about the Iranians.
