Today the reality is that Abiy Ahmed and his demoralized soldiers are in dire straits as the better-trained Tigray guerilla forces of the Tigray People's Liberation Front (TPLF), approach Addis Ababa. There is good reason to believe that Biden's Special Envoy to the Horn of Africa, Jeffrey Feltman, is manipulating events behind the scenes and not for peaceful resolution.
Nominally, the war was launched by Abiy because the Tigray state disobeyed the new government's covid ban on scheduled elections. Clearly the Tigray, who ruled Ethiopia as a minority ethnic group for almost three decades until 2018 - when it was forced by popular protests to yield rule to Abiy - were at a severe disadvantage, as Abiy gave a green light to Eritrea's brutal dictator, Isaias, to invade the Ethiopian Tigray state from the north while Abiy's military attacked from the south. Isaias's soldiers carried out murder of thousands of Tigray civilians and carried out war crimes including rape and pillage in what has been called ethnic cleansing. The Eritrean forces, estimated at some 80,000 occupied a third of the region of Tigray. All communications were cut by the invaders.
