Dr Geraint Hughes, from the blog Defence-in-Depth, refers to Oman in a wide-ranging article:
With reference again to Dhofar, the Popular Front still had a base of sympathisers within the local community even after their formal defeat in December 1975, and the province was by no means 'at peace' even after Qaboos declared the emergency over.
The main article is likely to be added to the COIN thread, maybe a new thread. The cited article alas is behind a link to a "pay wall" and entitled 'Demythologising Dhofar: British Policy, Military Strategy, and Counter-Insurgency in Oman, 1963–1976,' by Geraint Hughes, The Journal of Military History, 79:2 (April 2015): 423-456.
This article re-examines the civil war (1963–1976) between the Sultanate of Oman and the Popular Front for the Liberation of Oman (PFLO), particularly the U.K.’s support of the government. Using archival evidence and private papers, it argues that the counter-insurgency (COIN) campaign’s image as “population-centric” is flawed, and that the British and Omani governments relied more on military measures against the PFLO to recapture Dhofar province than on the “hearts and minds” and civil development programmes emphasised in traditional accounts. It counsels against using Dhofar as a possible example of indirect military assistance in contemporary COIN, arguing that the conflict’s specific historical characteristics may not be replicated now or in the immediate future.
