Oman needs to be viewed from the Indian Ocean rather than the Rub Al Khali, the vocab for Beirut can’t be applied to Sur. Oman was never really one country until 1971, or 1979 with the Imamate and the Dhofar Revolution but national integration was successful during Baba Qaboos, the Late Sultan. Oil was a booster pack but never had the leverage of Abu Dhabi. The locus of analysis itself is problematic. Oman should be compared to Ajman in UAE rather than Dubai.
The former Sultans are being reinstated at the National Museum at present, and large realignments happening with Riyadh via Ibri.
