Here is a declassified CIA April 1960 briefing for the United States National Security Council covering “the Somali area” along with pre-independence Congo. It discussed the “confused and explosive” situation involving impending Somaliland independence from Britain:
The issue of Somaliland independence or union with the “to be” Republic of Somalia was on the table for Somalis, their neighbors and the international powers when Somaliland was still a British Protectorate and Somalia was a former Italian Colony being administered by Italy as a UN Trust Territory. We are approaching the point at which Somaliland has functioned almost an equal amount of years as independently self-governed as it was a part of the Somali Republic (July 1, 1960) and its successors.
Same old same old. Sixty years later Ethiopia is still working to maintain its influence within the disparate entities comprising Greater Somalia in order to avoid what it perceives to be the existential threat of Somali unification and irredentism. However Jihadist insurgency since 2000 in much of the Horn of Africa, especially in northern Kenya and FGS, has become a wild card that threatens to upset all calculations by myriad external actors seeking to influence events within the region.
