No my friend..you have little knowledge about what is going on in Saudi Arabia and the UAE at least.. they have already diversified the oil industry to petrochemicals, mining, high tech and many other fields of interests to humans..their economy is 50% based on Oil now..Gas is not going to fade as OIL might (based on speculations!)..all this make your speculations just that..speculations..Even military wise..they are buying from many other sources than the US, China, Russia, France , GB, South Korea, Brazil, South Africa..etc, all with relevant TOT and JVs.. Even the US can't sell them any weapon system without ToT today..

2, 3 and 4 are all directly related to KSA oil reserves.
That means 95% of KSA exports are wholly or mainly due to their oil reserves.
As for the military, KSA is seeking a "security guarantee" from USA as quid-pro-quo of officially recognising the Zionist entity and at least 90% of its weapons by value comes from the US or its lapdog the UK.
This "balancing" is mainly just "optics" to try to show that the KSA regime is not wholly dependent on the US for its very survival.
