Western Sahara frozen conflict stirs intense diplomatic activity

Western Sahara remains Africa’s last unresolved decolonisation case. Listed by the United Nations as a non-self-governing territory, this region is the stage of a confrontation blending international law, regional rivalries, and energy security.

A striking contrast emerges: while the military situation on the ground appears completely frozen, international diplomatic activity has never been so intense and shifting.

1. Military stalemate versus a diplomatic whirlwind

Since the 1991 UN-brokered ceasefire between Morocco and the Polisario Front, military positions have barely moved. Morocco exercises de facto authority—administrative, economic, and military—over most of the territory. The Polisario Front, meanwhile, controls a sparsely populated desert strip east of the “Berm,” the fortified sand wall built by Morocco.

Yet this stagnation on the ground hides a burning diplomatic reality. The conflict has become deeply embedded in global geopolitical calculations, touching migration management, energy supply security, and great-power alliances.

2. The turning point of UN Resolution 2797

The adoption of Resolution 2797 by the UN Security Council on 31 October 2025 perfectly illustrates this new dynamic:

–A vote without consensus: While the resolution passed, China, Russia, and Pakistan abstained, and Algeria—the Polisario Front’s historic backer—refused to participate in the vote to signal its displeasure.

–A pro-Morocco anchor: The resolution extends the MINURSO mission’s mandate until October 2026, but above all reaffirms that negotiations must be based on the autonomy proposal submitted by Morocco.

–Strategic ambiguity: The UN does not formally validate Moroccan sovereignty or abandon the principle of self-determination. However, by imposing the Moroccan autonomy plan as the indispensable starting point, it creates an anchoring effect that gradually marginalises other options, such as full independence.

In Rabat, the resolution was celebrated in the streets as a huge diplomatic victory, reinforcing the sense that the international dynamic now tilts irreversibly in Morocco’s favour.

3. Historical roots of the deadlock

To understand the current impasse, we must recall the major historical milestones of this territory, colonised by Spain in 1884:

ICJ Advisory Opinion (1975)

Asked by Morocco, the International Court of Justice concluded that while historical allegiance ties existed between some Sahrawi tribes and the Sultan of Morocco, these did not constitute territorial sovereignty and did not override the population’s right to self-determination.

The Green March and the Madrid Accords (November 1975)

Morocco organised the Green March, sending hundreds of thousands of civilians across the border. Days later, Spain signed the Madrid Accords, abandoning its responsibilities as the administering power and temporarily sharing control between Morocco and Mauritania—without UN approval.

Mauritania’s withdrawal and stalemate (1979–1989)

Stricken by economic crisis and political instability, Mauritania renounced its claims in 1979. Morocco took over the vacated zone. Facing attacks by the Polisario Front (which had proclaimed the RASD), Morocco built the Berm, freezing the conflict into a military impasse by the late 1980s.

Creation of MINURSO (1991)

The UN ceasefire took effect and MINURSO was deployed to monitor peace and organise a self-determination referendum. That referendum never took place due to insurmountable disagreements over voter eligibility and the census of the Sahrawi electorate.

Conclusion: The triumph of political realism

What the analysis reveals is that the persistence of this status quo is no longer driven by law, but by an international environment that prefers ambiguity to rupture. Great powers and regional actors today give absolute priority to geopolitical stability, predictability, and preserving their strategic alliances.

Western Sahara thus remains suspended in a complex equilibrium: a definitive solution remains conceivable on paper, but for now it is politically too uncomfortable for the international community to implement.
