The United Nations Security Council’s decision to end the MINURSO mission in Western Sahara marks a decisive turning point—not just for the region, but for Spain and Europe as a whole. With the withdrawal confirmed on November 1, 2024, the 359 UN personnel, deployed since 1991, are preparing to leave, leaving behind a fragile status quo that has endured for decades.
The decades-long conflict pits Morocco, which controls 80% of Western Sahara, against the Polisario Front, backed by Algeria. The collapse of the UN mission threatens to destabilize an already tense balance, with potential ripple effects across the continent. Analysts warn that this withdrawal could trigger a cascade of consequences, from heightened migration pressures to geopolitical realignments.
What the MINURSO withdrawal means for Spain’s strategic position
Spain finds itself at a crossroads as the dissolution of the UN peacekeeping force removes a critical buffer in the region. While Madrid has publicly supported Morocco’s autonomy plan since 2022, the sudden UN withdrawal has exposed vulnerabilities in Spain’s southern flank. Analysts suggest Rabat may leverage this shift to press for control over airspace and territorial concessions, potentially reopening old grievances.
Ignacio Cembrero, a veteran observer of Hispano-Moroccan relations, highlights the accelerated drift toward uncertainty. The void left by MINURSO’s departure could embolden Morocco to take further action in the remaining 20% of disputed territory. Such a move risks provoking a harsh response from Algeria, escalating tensions into a broader regional conflict.
The Canary Islands emerge as the first line of pressure
The Canary Islands, already a hotspot for irregular migration, stand to bear the brunt of this geopolitical upheaval. In 2024, the archipelago saw over 46,000 arrivals—the highest annual figure in recent history. Experts anticipate that the power vacuum in Western Sahara could trigger new displacement waves, overwhelming Spain’s migration management systems.
Beyond Spain, the European Union faces growing exposure to the fallout. Hugh Lovatt, a senior analyst with the European Council on Foreign Relations, warns that instability in Western Sahara threatens to disrupt energy supplies, regional economic integration, and the EU’s external borders. The continent’s ability to respond to future crises may hinge on how swiftly it adapts to this unfolding reality.
Regional tensions and the risk of a domino effect
The breakdown of the UN mission could set off a chain reaction across North Africa and Europe. Morocco’s strategic interests in Western Sahara align closely with its broader regional ambitions, while Algeria’s historical support for the Polisario Front adds another layer of complexity. A single escalatory move—such as Morocco’s annexation of contested territory—could ignite a wider confrontation, drawing European stakeholders into the fray.
The stakes are high: from migration flows to energy security. As the dust settles on MINURSO’s departure, policymakers in Madrid, Brussels, and beyond must navigate this new terrain with caution—and urgency.
