Saudi Arabia has in the last few days seen its hold on the GCC countries loosen. To keep himself and his Kingdom in play, Foreign Minister Saud al Faisal, addressing the GCC, suggested that the Kuwait Foreign Minister lead the group to Washington protesting against the deal. Kuwait refused as did the UAE Foreign Minister who, instead, travelled to Moscow to sign different another affidavit.
There are two different appraisals of Saudi vulnerability in the context of the deal. First is the power struggle behind the curtains, a fierce war of succession. A regime so divided and debilitated is more likely to acquiesce in the new arrangement of power in the Middle East. But the opposite can also happen. A regime weakened internally is unlikely to be able to resist the ultra conservative clergy.
