Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. Federal troops reached Zalambessa on 13 Oct; Eritrea's note quotes an Ethiopian general on 27 Sep naming Assab as the ultimate destination (unverified); Rubio pointed Abiy to the 2018 framework [2]
  2. Army took Mekelle on 3 Oct; Belay told ENA on 4 Oct the Eritrean army has taken part in the fighting (his claim); Janes judges inter-state escalation very likely within one to 12 months [1]
  3. Ethiopia closed its Asmara embassy and expelled ten Eritrean diplomats; Eritrea cut relations; Afar's chief administrator told Al Jazeera Eritrean soldiers crossed into Afar (his claim) [3]
  4. Houthi forces took islands in the Bab el-Mandeb in September 2026 [6]
  5. EPFAS alliance of Fano, the TPLF and five other groups formed on 20 Sep 2026 [5]

Why it matters

Ethiopia closed its embassy in Asmara and expelled ten Eritrean diplomats on 1 Oct 2026; Eritrea cut all ties. Federal troops reached the Eritrean border at Zalambessa on 13 Oct. Janes judges a war between the two states very likely within a year; a thin prediction market on a related event leans the other way.

Why Likelihood 5 Pushes: ties cut; federal troops at the border from 13 Oct; Belay's claim of Eritrean army involvement; Afar administrator's claim of Eritrean troops in Afar; Janes judges escalation very likely within one to 12 months.

Why Impact 5 Threshold case one confirmed clash.

How it spreads

If

Between 1 Nov 2026 and 1 Nov 2027, the Ethiopian and Eritrean national armies clash directly, as confirmed by either government or two independent news agencies; Eritrean troops reported inside Ethiopia alongside rebels do not count unless the two armies engage.

Not under way

Channels 4 on the card

  1. CanadaNo Canadian loss sourced.
  2. Trade corridorThe Djibouti road and rail link carries 97.61% of Ethiopia's trade; troop moves near Afar would be read as a threat to it [1].
  3. Red Sea coastEritrea's coast faces the Bab el-Mandeb, where Houthi forces took islands in September 2026 [6].
  4. Debt and aidA war would weigh on Ethiopia's exit from default.

Three scenarios and their signposts

  1. S1

    Armed standoff

    Troops face each other at the border without a clash.

  2. S2

    Border war

    The armies clash around Adigrat, Zalambessa or Bure.

  3. S3

    Talks

    US-backed talks revive the 2018 framework.

The signposts of each scenario
PathSignpost
S1A Security Council statement on Eritrea's 14 Oct note
S2Ethiopian troop moves near Bure, in Afar
S3A dated meeting of the two foreign ministers

No probability is given for the three paths.

The other side

An end to the Tigray fighting, or US mediation on the 2018 framework [2], could reopen the embassies and the border trade of 2018 (Strature's view).
