Sahara occidental conflict frozen amid shifting global diplomacy

The Western Sahara remains Africa’s last unresolved decolonization case, classified by the United Nations as a non-self-governing territory. This disputed region has become a battleground where international law, regional rivalries, and energy security interests collide.

A stark contrast defines the current landscape: while military positions have remained virtually unchanged for decades, international diplomatic activity surrounding this conflict has reached unprecedented levels of intensity and fluidity.

Military stalemate meets diplomatic dynamism

Since the 1991 UN-brokered ceasefire between Morocco and the Polisario Front, the military situation has remained essentially frozen. Morocco exercises de facto control over most of the territory, administering its affairs economically, militarily, and administratively. Meanwhile, the Polisario Front maintains a presence in the sparsely populated desert region east of Morocco’s fortified sand barrier known as the Berm.

This military impasse belies a far more active diplomatic reality. The conflict has become deeply embedded in global geopolitical calculations, influencing migration flows, energy supply security, and major power alliances.

The UN Resolution 2797 turning point

The United Nations Security Council’s adoption of Resolution 2797 on October 31, 2025, marked a significant shift in the conflict’s trajectory:

• Divided vote: Though the resolution passed, China, Russia, and Pakistan abstained, while Algeria—longtime Polisario supporter—chose not to participate in protest.
• Morocco’s strategic gain: The resolution extended the UN Mission for the Referendum in Western Sahara (MINURSO) mandate until October 2026, but crucially reaffirmed that negotiations must begin with Morocco’s autonomy proposal as the foundational framework.
• Strategic ambiguity: While not formally endorsing Moroccan sovereignty or abandoning the principle of self-determination, the resolution creates an anchoring effect by making Morocco’s autonomy plan the starting point for future talks, gradually sidelining alternative solutions like full independence.

In Rabat, the resolution’s passage sparked widespread celebrations, reinforcing perceptions that international momentum is irreversibly shifting in Morocco’s favor.

Historical roots of the deadlock

Understanding the current impasse requires examining key historical milestones that have shaped this territory since its Spanish colonization in 1884:

International Court of Justice Advisory Opinion (1975)

The ICJ concluded that while historical allegiances existed between some Sahrawi tribes and the Moroccan Sultan, these did not constitute territorial sovereignty and did not negate the population’s right to self-determination.

The Green March and Madrid Accords (November 1975)

Morocco organized the Green March, mobilizing hundreds of thousands of civilians to cross into the territory. Shortly after, Spain signed the Madrid Accords, transferring administrative control to Morocco and Mauritania without UN approval—though the agreement was later deemed invalid by international bodies.

Mauritania’s withdrawal and escalation (1979–1989)

Facing economic collapse and political instability, Mauritania abandoned its claims in 1979. Morocco swiftly consolidated control over the vacated zone. In response to Polisario Front attacks (which had proclaimed the Sahrawi Arab Democratic Republic), Morocco constructed the Berm, effectively freezing the conflict in a military stalemate by the late 1980s.

Establishment of MINURSO (1991)

The UN ceasefire took effect, and MINURSO was deployed to monitor peace and prepare for a self-determination referendum. That referendum never materialized due to irreconcilable disputes over voter eligibility and the electoral roll of Sahrawi residents.

Conclusion: The triumph of political realism

What emerges from this analysis is that the conflict’s persistence is no longer driven by legal frameworks but by an international environment prioritizing geopolitical stability, predictability, and the preservation of strategic alliances over definitive resolutions. The Western Sahara remains suspended in a delicate balance where a final settlement remains theoretically possible but politically unfeasible—at least for now.
