Along the ancient corridor of the Nile, Egypt has pledged $100 million to build water infrastructure across the basin's southern reaches — a gesture that is at once an act of partnership and an assertion of principle. Cairo is offering dams, solar wells, and technical capacity to neighboring states while simultaneously drawing a firm line against unilateral actions it believes threaten its own survival. In a region where water is both lifeline and flashpoint, this fund represents Egypt's attempt to lead through generosity without surrendering the rights it considers existential.
