Settled — the dispute is formally resolved6%
Unresolved — no combat, no settlement84%
Both remain below the threshold of combat. They differ in whether the dispute is resolved or simply remains open.

A 90% chance the coming year stays below the threshold of combat — a Nile water-security standoff where the kinetic option is near-infeasible and self-defeating for both.

Strategic timeline
Historical
  1. 1929An Anglo-Egyptian treaty grants Egypt veto rights over upstream Nile projects.
  2. 1959Egypt and Sudan allocate most of the Nile's water between themselves, excluding upstream states.
  3. 2010Upstream basin states, including Ethiopia, sign a Cooperative Framework Agreement.
  4. 2011Ethiopia begins construction of the Grand Ethiopian Renaissance Dam on the Blue Nile.
  5. 2015Egypt, Ethiopia and Sudan sign the Declaration of Principles.
  6. 2020Ethiopia begins filling the dam's reservoir without a trilateral agreement.
  7. 2023Ethiopia announces completion of the fourth and final reservoir filling.
Recent developments
  1. 2024–2025Ethiopia proceeds with further reservoir-filling phases while trilateral talks remain frozen.
  2. 2025The Grand Ethiopian Renaissance Dam becomes operational.
  3. Early 2026Egypt demands binding water-management guarantees before resuming talks.

Curated for strategic significance, not completeness. The timeline provides context; the Foundation Paper explains the assessment.
