While most global leaders’ attention is on the Ukraine war, the world’s bloodiest armed conflict continues to rage in the northern Ethiopian region of Tigray, where half a million people are thought to have died.On the battlefields, an estimated one million troops are engaged in the offensive, making it the biggest conflict in the world right now, according to Kjetil Tronvoll, an anthropologist and conflict professor at Oslo New University College in Norway.According to Professor Tronvoll, whose more than 30 years of research and fieldwork has focused on Ethiopia and Eritrea, the military strategy used by Ethiopian troops mirrors that of the First World War: using infantry to push large “human waves” of soldiers to breach Tigrayan defence lines.“One thing we know about the history of Tigray – and I have been studying that history for over 30 years – when they say this is an existential war and they will never give up, that is true, that is proven.”Though there have been repeated condemnations from around the world and demands for humanitarian access into Tigray, Professor Tronvoll criticised the lack of meaningful action from the West.The Tigrayan regional government expressed reservations about the impartiality of General Olusegun Obasanjo, the former leader of Nigeria, who was “hand picked” by the Ethiopian Prime Minister Abiy Ahmed to lead negotiations under the AU, Professor Tronvoll said."
