I have known a number of people who have escaped from Iran in recent decades, most because they were Christians who feared for their lives.
Prince Reza Pahlavi's father was the Benevolent Monarch that would have guided Iran to a modern Free Republic but for the Commie Scourge Jimmah Carter, Traitor to all Free Peoples.
This would have required Prince Pahlavi to continue his Father's policies until the Iranian People were educated enough to protect the Constitutional Republic he created.
The last thing Iranians want is the return of the Shah.
