Better than Iran taking over. What about the Christians who reside in Iraq? What is their fate?
Are you kidding me?
The Iranis allow Christians, Jews, Zoroastrians, Yazidi to practice their faith openly -- there are Churchs, Synagogues, Agiaries in Iran
Saudi Arabia does NOT allow you to so much as bring a Bible or a crucifix into the country.
It is better if Iran took over.
