I agree about Eye-rack - to that list I'd add Eye-ran. Though the advantage to these pronunciations is they provide a ready-made "ignoramus alert" - opinions courtesy of Fox news.
And who hasn't heard "Eye-talian" -- in all three instances, I don't think it is something that can be casually excused as a minor regional difference in pronounciation. In the last case in particular (Italy/Italian), the sources I can find quickly on line all indicated that the pronounciation was intentionally derogatory and pejorative (first usage these sources identified is from 1848) and I think that reading that same derogatory intention into the mis-pronounciation of Iraq/Iraqi or Iran/Iranian is quite reasonable.
