The Grand Ethiopian Renaissance Dam is once again at the heart of regional politics. Ethiopia last week officially inaugurated the project in a nationally televised spectacle, with it hailed by Prime Minister Abiy Ahmed as a “historic achievement” on par with Ethiopia’s victory at Adwa. For Cairo, it is a direct existential threat to the lifeline of more than 110 million citizens. For Addis Ababa, it is framed as a 14-year development project. Between these two starkly opposed narratives, the Nile crisis has reignited — laden with mistrust, competing claims and difficult choices ahead.
