Did I specify a time? You spouting nonsense to avoid answering the question. Oromos have been killing Somalis, expanding and forcibly assimilating Somalis. You made it clear that you don't support Somalis and Oromos reconcilliating and uniting with each other upon Islam, well then you are nothing but an xoolo, every ethno-nationalist is an xoolo and deserves only to be deleted from the planet.that's fine, because somali's expanded into much of the land they occupy today too, it's not like they didn't conquer more than others, so to point out the oromo expansion while ignoring somali's expansion is a bit hypocritical.
to answer you question: that's not possible at the moment, let's be honest here, somali's cannot even unite with each other, we oromo have our own problem based on political history and not religion, and then the afar have their own problems being outnumbered and subjugated by the more numerous habesha in eritrea, the issa in djibouti, and in ethiopia, etc.
either way, you can consider me an enemy, I honestly do not care, because we oromo can defend ourselves quite well and have no shortage of warriors.
