You are probably right.
But..... I think the Hajj is the reason for the change.
The primary task and responsibility of the Saudi King is Keeper of The Two Holy Mosques. He has a responsibility to the Islamic world. That includes Iran that is prohibited from the Hajj since there was an attack.
Attendance to the Hajj is one of the Five Pillars of Islam as stated by Mohammed himself. So, some accommodation must be made if there is strong assurance of religious rather than political attendance
Any way, We’ll see who is the real power...... the Prince or the Mullah
Is there something to be said for those different sects fighting each other?
I say let the Chicoms have the Middle East. They’ll keep a lid on the violence like they do with Tibet. Let them be the on the receiving end of the terror.
