Having just returned from there and being subjected to the wonderful hospitality of the Iranians, the Kishair crews and Air Traffic folk your comment is nothing less than a narrow minded and uneducated. Time you got out a bit and saw the real world.
Whilst the Iranian aviation market may be reasonably closed and the political environent a little insular, Iran to date is the friendliest country I have ever visited. If things ever did improve for foreign employment I think it would be a great experience.
