Which language (afar or Oromo) is closer to Somali anyways? I don't know much about the Issas and my view is mostly superficial.How do the Afar manage to live there? I have heard they have T1a, I assume those are assimilated Dir. I would say Gadabursi and Issa are more related. In Djibouti, Somalis and Afar didn't marry until quite recently. In fact, it was frowned upon. This could be on both sides. The Afar engage in first cousin marriages. And Somalis are ultra endogamous. I will admit, the Afar are very combative, which is very Somali-like. Albeit the Afar have a slightly older language than Oromo and Somali, respectively. I think Somalis are the renegades of the Eastern Cush family.
In Ethiopia the Afar are regarded as warriors are left alone for the most part. The government in a ploy to garner more support by them has been offering them housing and education to resettle them in cities but they have refused for the most part. I think it's a long term strategy to annex Eritrean Afars.
Are you from dj by chance?
