Let me biol it down to its essence! It is all about life and death struggle for Ethnic Capture of the Ethiopian State! It is all about a race for an upper hand in the Ethnic Balance of Power. It is a hidden and complex Ethnic war (both political and military) for the Control of the Ethiopian state. Now the multitude of Oromuma groups all the way from Shene to Jawar to Merera to Shimels & Abiy are trying to negotiate a Formula for Oromo Control of the State! This is the essence!
Of Course , the Tigray settlement will Trigger Amara, will Trigger all other Ethnics!
