The key here is Arab Sunni Muslim world. The Arabs consider themselves to be the best Sunni Muslims and the rest of the Sunni Muslim world resents them for it. So Erdogan of Turkey, a Sunni Muslim, will continue his pursuit of the revival of the Ottoman Caliphate. The Arab Sunni Muslims on the Arabian peninsula are pursuing the old Muslim tactic of taqiyah, i.e., they will ally with their lesser kafir enemy, Israel (the Little Satan), temporarily to fend off/ defeat their more imminent threat, Persian Shia Iran. If that is achieved then they will return back to denouncing the Little Satan. The Qu'ran cannot be changed.
I’m not so sure. While I don’t believe this is a prelude to unicorns, skittles and flying pigs with heavenly choirs proclaiming eternal peace, I do think this is more than just taqqiya. There’s a lot of the younger set over there that not only were educated in the West, but due to the Internet have Western friends and increasingly a more Western mindset, with all that that entails. Note that this king was convinced by the younger set to let women drive in 2017 and is (for Saudi Arabia) Westernizing at a breakneck pace, with his son starting to literally kill the old fundamentalist arsehats.
