Two kinetic outcomes
Settled — a settlement is in place5%
Open — the dispute continues below the threshold of combat, no settlement69%
Both remain below the threshold of combat. They differ in whether the underlying dispute has been settled.
Limited military action — military force is used, short of a major campaign18%
Major operation — a full-scale or multi-axis military campaign8%
Both cross the threshold of combat. The threshold is the use of military force: shots fired, a strike, an armed seizure. Ramming, water cannon and boardings remain below it, however serious, unless military force follows.

A 74% chance the coming year stays below the threshold of combat — a standoff held by mutual incapacity rather than agreement.

Strategic timeline
Historical
  1. 1952The United Nations federates Eritrea under the Ethiopian crown as an autonomous unit.
  2. 1961The Eritrean Liberation Front begins an armed struggle for independence.
  3. 1993Eritreans vote for independence in a UN-monitored referendum.
  4. 1998–2000The two fight a border war centred on Badme, with tens of thousands of casualties.
  5. 2000The Algiers Agreement ends the war and establishes a boundary commission.
  6. 2002The boundary commission awards Badme to Eritrea, and Ethiopia declines to implement the ruling.
  7. 2018The two sign a Joint Declaration of Peace and Friendship.
  8. 2020Eritrean forces enter Ethiopia's Tigray region alongside federal troops.
  9. 2022The Pretoria agreement ends the two-year war in Ethiopia's Tigray region.
Recent developments
  1. 2024–2025Military build-ups continue on both sides of the frontier amid frozen diplomatic relations.

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