You can't compare Ogaden to Somaliland. Somaliland is literally the same as Somalia: same people, religion, culture. Ogaden is not at all the same as the rest of Ethiopia: they are Christian, Amhara, Tigre, Oromo etc with each their own culture. Ogaden got way better chances to become independent than Somaliland
Amhara will jointly heir brothers in Abyssinia(land of habashi), Oromo will have Oromia. Ogaden will be back to their brothers in Somalia. Remember we went to war in 77 to free Them. 1/2 million Ogaden refugees in Somalia almost collapsed our economic. Show some grateful to our martyrs in 77.
