1) The UAE has its "Abu Dhabi Crude Oil Pipeline" (see https://en.wikipedia.org/wiki/Habshan%E2%80%93Fujairah_oil_p...) to Fujairah export terminal on the "Gulf of Oman" bypassing the choke-point of "Strait of Hormuz" entirely. Given the current blockade of the strait and its uncertain future, Fujairah is now central to crude oil shipments for the World Market.
2) Thus far, the UAE has been prevented from maximizing its revenues due to OPEC/OPEC+ production caps which is no longer acceptable due to global needs. It can now chart its own independent course by ramping up production and earn hard currency which can be its leverage against an uncertain future. For instance, UAE just signed a deal with South Korea to give it guaranteed "priority access" (meaning first before others) and "joint stockpiling" (for world market) of 24 million barrels. Other countries in Asia who have storage capabilities are also "tripping over each other" to cut similar deals with UAE. This is once-in-a-lifetime opportunity not to be missed.
3) Discontent with OPEC/OPEC+ and its members since the current conflict has made it clear that nobody will come to its aid when the chips are down (other than the US). It is "every man for himself" now and thus UAE has decided to chart its own independent path.
This is very welcome news and i hope other OPEC/OPEC+ members will also follow suit in their own national interests.
1) The pipeline to Fujairah has capacity of 1.5m barrels per day, i.e. less than hald of UAE's current oil production. They still need Hormuz badly.
2) They can gain by increasing their production, IF they can get that out through Hozmuz. And IF (after Hormuz is opened) other OPEC+ countries DO NOT decide to do the same and the price of oil collapses.
3) US did not meaningfully came to their help. The high-end air defense systems were reserved/moved to Isreal. They mostly defended themselves, with the stuff they bought over the years from the US. A slightly cynical take would be 'classic protection racket'.
4) The national interests of other OPEC members are best served by being united against greater forces from outside region, not by fracturing and bickering among themselves. This is classical divide and conquer.
