Sorry. But any dealings or involvement with the Saudis is repulsive. The Saudis protect and finance the Wahhabi. It was the Wahhabi that motivated, recruited and financed the 9/11 terrorists. Their perverse teaching of Islam not only molded the consciences of the 9/11 terrorists but also the barbaric Sunni jihadists who perform unspeakable crimes and terror. What’s more Saudi intelligence and the “royals” were well aware of the 9/11 plot and did nothing to warn the American government. Bush sadly never held his Saudi buddies accountable and instead invaded Iraq. Trump is making a bad error by giving the vile Saudis the validation of a Presidential visit.
In many ways it was initially the other way around. The house of Saud transitioned from the second empire to become the third as promoted and pushed by the Wahhabi influenced tribes.
The house also profited by the "movement" of the islamic push against nomadic life as being outside strict muslim control. That movement regionally was the Ikhwan who became the militia under al-Saud and later the National Guard of the kingdom. They went beyond his control, parts rebelled and were put down in 1929 in the Ikhwan revolt.
When the word ikhwan is used in Arabic it means Brotherhood and can mean Muslim Brotherhood in Egypt and elsewhere or the Ikhway movement in Saudi Arabia. Both are conservative jihadist.
In part these groups begin to explain why the western use of the term fundamentalist when referring to factions in Islam is stupid -- they are all fundamentalist, there is no moderates, only slackers like the bedouin groups living as nomadic tribes.
A "moderate" muslim in most of the world is a revolutionary apostate and is allowed to be put to death by others without recourse.
This is as difficult as learning the Reddit universe or ancient Hindu beliefs -- it is impossible for discourse without the historical understanding.
