This kind of comeuppance was just waiting to happen to the KSA. The USA panders to them because they have oil. Arab countries pander to them because of Mecca and Medina. If it wasn't for these they may also be important from a geographic point of view in strategic defence, but that is about it. As we transition out of carbon based fuel they will have less money. The Saudi's dont manufacture anything of importance beyond oil. Once that ends, they are screwed. This pulling out business by companies will speed this process.
