Western Sahara
Western Sahara is Africa's last major decolonisation question. Spain withdrew in 1975; Morocco and Mauritania divided the territory. The Polisario Front, backed by Algeria, fought a guerrilla war until a 1991 ceasefire. A UN-promised self-determination referendum has been delayed for over 30 years. Morocco controls ~80% of the territory and has invested heavily in infrastructure to consolidate its claim. The US recognition of Moroccan sovereignty in 2020 fundamentally altered the international diplomatic landscape.
Key Fact
A UN-promised self-determination referendum has been delayed for over 30 years. Morocco controls ~80% of the territory and has invested heavily in infrastructure to consolidate its claim. The US recognised Moroccan sovereignty in 2020 in exchange for Morocco normalising relations with Israel.

Foreign Policy Analysis
Three-level analysis: systemic, state, and individual factors
Systemic Level
Western Sahara is a decolonisation conflict that has been progressively reframed as a regional stability question. The US recognition of Moroccan sovereignty in 2020 — a transactional exchange for Morocco-Israel normalisation — demonstrated that great power interests can override the self-determination principle that the UN framework is built on. Algeria's support for Polisario is driven by regional competition with Morocco as much as by solidarity with the Sahrawi people. The conflict is also a proxy for the broader Moroccan-Algerian rivalry, which has closed the Algerian-Moroccan border since 1994.
State Level
Morocco's position has hardened: it offers 'broad autonomy' within Moroccan sovereignty but will not accept a referendum on independence. This position has gained significant international support following the US recognition. The Polisario Front insists on a self-determination referendum as the only legitimate path, consistent with UN resolutions. The SADR is recognised by ~84 states, primarily African and Latin American. The UN Security Council's inability to enforce its own resolutions — due to French support for Morocco — has made the UN framework increasingly irrelevant.
Individual Level
~170,000 Sahrawi refugees have lived in camps near Tindouf, Algeria, for nearly 50 years. A generation has grown up in the camps with no experience of Western Sahara itself. The population within Moroccan-controlled territory has been substantially altered by Moroccan settlement. The Sahrawi identity — nomadic, tribal, distinct from both Moroccan and Mauritanian — has been maintained in the camps but is under pressure from assimilation in the Moroccan-controlled areas.
Policy Paths
Three documented approaches to resolution — with their consequences
Moroccan Autonomy Plan
Western Sahara as an autonomous region within Morocco, with a locally elected government and significant self-governance powers.
Consequences
The position of Morocco and its international supporters (US, France, Spain). Does not provide for a referendum on independence. The Polisario Front and Algeria have rejected it as inconsistent with the right to self-determination.
Examples
South Tyrol (1992) — genuine autonomy within Italy. The Moroccan plan is less detailed and has not been negotiated with the Polisario Front.
Self-Determination Referendum
A UN-supervised referendum on independence, as originally promised in 1991 and mandated by UN Security Council resolutions.
Consequences
The position of the Polisario Front, Algeria, and most African states. Blocked by Morocco's refusal and French veto protection in the Security Council. The voter registration question — who counts as a Sahrawi eligible to vote — has been the primary technical obstacle.
Examples
East Timor (1999): UN-supervised referendum on independence; 78.5% voted for independence; recognised internationally. Eritrea (1993): referendum produced 99.8% vote for independence from Ethiopia.
Partition Along the Berm
Formal recognition of the existing de facto division: Morocco controls the western ~80%; the SADR controls the eastern ~20%.
Consequences
Would formalise the existing situation but would leave ~170,000 refugees in Algerian camps with no right of return. Neither Morocco nor Polisario has accepted this option. Would set a precedent for partition as a resolution mechanism.
Examples
Korea: a de facto partition that has persisted for 70 years. Cyprus: a de facto partition that has persisted for 50 years.
Conditional Equilibrium
Western Sahara's frozen status has been maintained by a balance of forces: Morocco controls the territory and has French and US diplomatic protection; Polisario has Algerian backing and UN legitimacy. The 2020 US recognition shifted this balance significantly in Morocco's favour. The resumption of low-level hostilities in 2020 suggests the ceasefire equilibrium is under pressure. The conflict is approaching a point where the choice is between a negotiated autonomy arrangement and a resumption of sustained armed conflict — the ceasefire alone is no longer sufficient.
Escalation Risk
Probability assessment and specific trigger conditions for conflict escalation
The resumption of hostilities in 2020 and the absence of any diplomatic progress suggest the conflict is at risk of escalating from low-level skirmishing to sustained armed conflict. The primary constraint is Polisario's limited military capacity relative to Morocco's. Algeria's potential direct involvement is the highest-risk scenario.
Algerian direct military involvement
low probabilityAlgeria has so far confined its support for Polisario to logistics, training, and diplomacy. Direct Algerian military involvement — triggered by a Moroccan military operation that threatens Algerian territory or interests — would transform the conflict into a regional war.
Polisario military escalation
medium probabilityPolisario's resumption of hostilities in 2020 has so far been limited. A decision to escalate to sustained guerrilla warfare — particularly targeting Moroccan infrastructure — could produce a Moroccan military response that draws in Algeria.
Refugee camp collapse
low probabilityThe Tindouf camps have been sustained by international humanitarian aid for nearly 50 years. A collapse of international funding — or an Algerian decision to close the camps — could produce a humanitarian crisis and a large-scale population movement.
Historical Analogue
East Timor 1975–1999: a territory occupied by a neighbouring power, with a liberation movement backed by a regional patron, that eventually achieved independence through a UN-supervised referendum after 24 years of occupation.
