WI: Divided Libya

In this scenario: Tripolitania, Cyrenaica and Fezzan are all granted independence and not unified into a single Libyan nation-state. How is North Africa changed by this?
 
You have to find a way to deal with Arab resentment to get the votes in the UN Assembly - not too difficult - and to find a way to sell tripartition, as most believed in a unitary Libyan nationhood (much harder).
 
Would Fezzan become an African version of Mongolia, a sparsely populated state home to nomadic peoples like Tuaregs and Berbers?
