Another update via Defence-in-Depth (Kings War Studies @ UK Staff College aothors) by Geraint Hughes:
Thanks to the declassification of British government archives under the 30 Year Rule we now have greater knowledge of the covert operations conducted during this conflict, in the form of cross-border raids conducted into the former People’s Democratic Republic of Yemen (PDRY), otherwise known as South Yemen.
He concludes, with my emphasis:
from the documentary evidence available British officials in Oman or London did not expect that the cross-border attacks would have any strategic effect against the insurgency in Dhofar itself. Operation Dhib was ultimately conducted as a limited action to satisfy Sultan Qaboos’ wish to punish South Yemen for backing the PFLO, and in this respect it was a covert operation intended to influence an ally, rather than an enemy.
