You are correct and Gulf Arab ruler would exploit the hell out of that union. These sheikhs worship the ground western leaders walk on.I highly doubt any of this is true. Considering if William even looked at another woman, she was on the cover of a magazine as the next Princess of Wales.
If William had indeed had a relationship with Shamsa, Mohammed would have exploited it to his benefit.
With the rise of Mohammed bin Salman they are asserting themselves more. But MBZ is the one behind the move.
I could tell you all kinds of stories. I only wish I saw this thread sooner.
