Arguably self serving. We Americans have nothing to gain by simply badmouthing the Saudis out of spite here.
The Saudi Air Force is not a professional service, least of all the pilot corps. The Saudi Air Force is little more than a playground for spoiled princes, of which
YOU would know better than anyone here how many of them there are and what they are like. These princes have the attitude that at least the Saudi society, if not the world, revolves around them. It is a 'privilege' for us foreigners to be around them, let alone teach them anything.
If any prince, no matter how dubious the familial tie to the Royal Family, is ignorant of anything, it is because he is too important and too busy with other things, therefore, we foreign instructors should know our place and teach them shortcuts so they can get on with the kingdom's business. Standards are lowered. Mistakes are corrected by others, not by the person who made the mistake, because self corrections are beneath a prince. Exams are typically pencil whipped. Schedules are usually ignored. Sh1tty radio discipline. Jets are flown poorly trimmed, costing fuel and create delays. In-flight emergency (IFE) calls are capricious and usually unwarranted by our standards.

I have seen an external wing tank that failed to transfer written up as
'BATTLE DAMAGE'...!!!
No respect for the maintainers, least of all for their own Saudi countrymen. I suspect that it has more to do with the knowledge that most Saudi enlisted do not want to be wherever they are and have a poor attitude towards their jobs, so these princes are leery of any Saudi enlisted personnel even washing the jets. They know that despite the foreigners being technically mercenaries in the employ of the Saudi government, at least these mercenaries came from a superior military, have superior work ethics, and therefore worth their salary.
May be the Saudi Air Force have matured some since then, but not from testimonies I received.
