They’ll stab you in the back every time.
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
The Sauds are weighing the imminence of Iran’s nuclear warhead with the likelihood that Biden will do anything to stop Iran from using it. Time to make nice with the mullahs.
