KSA please!
When the time is ripe. You don't want a reason to throw tinder into the Sunni Shia already on fire tinder box. Things need to happen gradually. As I've pointed out. None of the GCC countries would make major moves like this without KSA approval.
One of the funniest things I saw was Erdogan threatening to close his embassy to the UAE over this, as if Turkey doesn't have ties with Israel...
This is all about a leadership struggle in the Muslim world. Erdogan is trying to take the Sunni leadership from the KSA after they took it from Egypt after the Egyptians signed a Peace treaty with Israel.
