Sorry I can't help but poke a little fun at the required dress code. I even got on Elon ("Dark maga")with a friend when my buddy got a black hat. Lol.
Your video reminded me of a historian's account of Iran in the 1960-70s. Before the C👁️A established the Muslim extremists to replace the self governing Persian people, they looked much like Westerners. I heard that they were culturally similar in some ways good or bad . Then there was some manipulation with the students and the trrist groups. Jimmy Carter administration. That's when the Ayatollah's denomination was given his political powers if I understand right. That made the middle east destabilized and easier for the powers that shouldn't be to manipulate Iran, Israel, etc..
Is that roughly how you understand that change?
