Saudi Arabia and UAE are absolutely not going to be promoting Islamism (Qatar is more complicated). Islamists are the biggest enemies of entrenched authoritarian regimes in most of the Middle East, so even ones with a veneer of religion are trying hard to gain legitimacy as secular nationalist dictators. For example remember that one story about the UAE being like "Britain harbors dangerous islamists? The translation here is "this foreign liberal democracy is harboring enemies of my authoritarian regime." If anything both of them (but probably not (Qatar) are already pushing for more bellicose US policy in the Middle East, because they're vassal regimed whose survival depends on the continued interest of their imperial masters.

the Middle east countries have been desperately trying to diversifying , because they know oil and gas will dry up a few decades. and they have spent alot of money recently sportwashing themselves.

With a hefty dose of Israel support because if they went against Israel, 1, the US wouls get angry and 2, people would start questioning why the big rich Muslim countries aren't doing anything to help their brothers and sisters in Gaza.
