And we also know that Oman has been the main nay-sayer to the Saudi project for turning the GCC into a true union; recently, it openly threatened to reconsider its GCC membership if the union plan goes through. Oman has also, along with the UAE, opposed projects for a joint GCC currency.
I don't want to overemphasize this as it isn't totally new. Oman, which has far more coastline on the Indian Ocean than on the Gulf, and once ruled an empire ranging from Zanzibar to India, has always marched to a somewhat different drummer than the other GCC states. It has always sought to keep lines open to Iran, even in the worst days of the Iran-Iraq war, which helped spur the birth of the GCC in 1981.
But at a time when Saudi Arabia is feuding with its US ally and dismayed by events in many parts of the region, it also finds the GCC disunited. (Qatar's new ruler may be a little less the maverick his father was, but it's still early.) In a time of major realignments, add Oman's recent assertiveness to the list.
