Well the key word is occupational. They are just a regular regime, not occupational. And they take “handouts” from their ally of choice just like every other state. There’s no occupation going on and they aren’t a puppet state.
If you topple the Saud dynasty then another regime would take their place. They aren’t suppressing some kind of egalitarian wellspring. If you disagree then I have 2000 years of history to show you.
As I said, if they didn’t have support from the US it would just be some other country. And if it weren’t the Sauds it would be some other totalitarian body.
They derive their power from their natural resources. If history is racist then perhaps we should abolish history books?
