Algerian-Moroccan Rivalry: From the Sahara Dispute to a Contest for Influence in the Sahel
The News:
On October 11, 2026, Algeria arrested 61 Moroccans on charges of plotting sabotage, amid questions over the evidence. On October 22, 2026, Mauritania denied any territorial claims over Lagouira and reaffirmed its ties with Morocco.
Why It Matters to Washington:
The United States treats Algeria and Morocco as counterterrorism partners but has lost the ability to mediate between them since taking sides on Western Sahara. This tension matters because it blocks regional cooperation Washington needs on terrorism, migration and energy, just as its direct influence in the Sahel declines.
The key question is whether the detainee case is a short-term pressure card ahead of the vote or the prelude to broader escalation. The dispute is no longer only about Western Sahara but about who leads the Sahel and West Africa, and reading it with old tools will miss its essence.
Implications:
The tension becomes a tool in the contest for regional influence, while Mauritania’s position tips part of the balance toward Rabat.
Points to Watch:
- Timing of the Arrests: They came days before the Security Council’s closed consultations on Western Sahara, suggesting a pressure card.
- Mauritania, the Silent Swing Actor: Its denial of claims over Lagouira signals Nouakchott moving closer to Rabat, weakening Algeria’s position in the four-party talks.
- The Economic Dimension of the Rivalry: Two competing gas pipelines, and a Moroccan Atlantic initiative versus an Algerian military deployment. The Sahel has become an extension of the dispute.
Scenarios:
1. A War of Statements Without Field Escalation (Likelihood: High | Ongoing)
Tension stays in the media and official rhetoric. Relations have been severed since 2021, few escalation tools remain, and neither side has an interest in direct confrontation. For Washington: Manageable, but it prevents any Maghreb cooperation on migration and terrorism.
2. Algerian Punitive Measures After the Vote (Likelihood: Medium | November – December 2026)
Fast-tracked trials with harsh sentences for the detainees, mass deportations or restrictions on Moroccan residents, met by an international Moroccan campaign on behalf of its nationals. Indicators: Referral of detainees to security courts, statements by rights groups. For Washington: Harder to maintain a balanced relationship, with possible pressure to take a position on the humanitarian dimension.
3. Third-Party Mediation (Likelihood: Low | Undetermined)
A Gulf state moves to prevent a new flashpoint amid the Iran war, starting with a partial release of detainees. Indicators: Envoy visits to both capitals. For Washington: Support from behind the scenes, since its partiality precludes direct mediation.
