The Saudi King, and the next 2 or 3 princes in line for the throne are all over 80, and in questionable, if not declining health...after them, there is no clear favorite for succession, just several dozen who have led indolent lives, spending money like drunken sailors, and probably not capable of ruling...let alone unifying the country.

I suspect that Iran senses that the Saudi throne is rotten, and might be toppled easily....The Saudi tribe is a minority one, and there decades long embrace and funding of Wahabiism ( buying off the radical clerics) may now come back and bite them on the ass..

The Arabs will never allow the Persians to control Mecca and Medina.

"I suspect that Iran senses that the Saudi throne is rotten, and might be toppled easily.."

The winning response to the article's premise. I do not doubt the fifth column is in place waiting for a signal. As it would be a political uprising, i.e., an Arab Spring, current US leadership would welcome it. No invasion forces needed, few if any shots fired.
