Executive Summary
The Sahel in 2026 is no longer a fragmented set of national insurgencies; it is a single regional conflict system. The April–May 2026 JNIM-Azawad Liberation Front (FLA) joint offensive across Mali — the largest coordinated rebel campaign since the 2012 Tuareg rebellion, which struck Bamako and Kati directly, killed Mali’s Defence Minister Sadio Camara, and wounded the intelligence chief — has terminated any remaining illusion that the Alliance of Sahel States (AES) of Mali, Burkina Faso and Niger can deliver security on a national basis. The three juntas have responded by activating a 15,000-strong joint anti-jihadist force and conducting joint air campaigns over Malian territory, formalising the AES as a confederal counter-insurgency bloc.
But the offensive also exposed the structural failure of the post-2022 strategic settlement. The AES expelled France, Barkhane and MINUSMA, denounced ECOWAS, embedded Russia’s Africa Corps as the primary external partner, and bet on a militarised counter-terrorism model. Three years on, JNIM controls or contests more rural territory than at any point in the war; the Islamic State Sahel Province (ISSP) holds the Mali-Niger-Burkina tri-border zone; the Liptako-Gourma ungoverned space has become the world’s most violent jihadist epicentre by ACLED metrics; and climate stress, food insecurity and forced displacement now constitute a structural amplifier of conflict that no AES military instrument addresses.
This assessment maps the integrated regional system: the AES political-military architecture, the JNIM / ISSP threat ecology, the climate-migration-conflict nexus, the Lake Chad Basin’s interaction with the central Sahel, and three escalation scenarios.
Strategic Context
The Sahel war has run since 2012, but its strategic shape changed in 2020–23 with the cascade of coups in Mali (2020, 2021), Burkina Faso (January and September 2022), and Niger (July 2023). The juntas converged on a common strategic doctrine: rejection of French / Western counter-terrorism architecture; embrace of Russian paramilitary support; rejection of ECOWAS political conditionalities; pursuit of a militarised, sovereigntist, anti-colonial framing of the conflict. The AES, formalised in September 2023 and converted into a confederation in 2024, codified this doctrine.
The wager was that, freed from Western constraint and supplied by Russian operators, AES forces could deliver decisive military results. That wager has now empirically failed. Russian / Africa Corps support has provided drones, training and propaganda capability, but it has not generated battlefield outcomes. The April–May 2026 JNIM-FLA campaign — striking the AES capital itself and decapitating Mali’s defence apparatus — is the empirical refutation.
Order of the Conflict System
Insurgent / non-state armed actors.
- Jama’at Nusrat al-Islam wal-Muslimin (JNIM) — al-Qaeda-aligned coalition formed 2017 from AQIM-Sahara, Ansar Dine, MUJAO and the Macina Liberation Front. Now deeply embedded in central / northern Mali, expanded across most of Burkina Faso, operational in western Niger, with probing presence into northern Togo, Benin and Côte d’Ivoire. The system’s dominant insurgent actor.
- Islamic State Sahel Province (ISSP) — formerly ISGS, the IS-aligned franchise dominant in the Liptako-Gourma tri-border. Periodically clashes with JNIM but coexists in a competitive equilibrium that, paradoxically, has stabilised both groups’ rear areas.
- Azawad Liberation Front (FLA) — Tuareg / northern Malian successor coalition to the CMA, allied with JNIM in the 2026 offensive. Demonstrates the strategically critical fact that AES counter-insurgency has now fused jihadist and ethno-nationalist insurgent axes into a single front.
- Lake Chad Basin / Boko Haram / ISWAP — operationally distinct system but linked to the central Sahel through climate-displacement vectors and northern Nigerian instability.
State / pro-state forces.
- AES joint force — 15,000 personnel as of mid-April 2026, up from 5,000, conducting joint air campaigns over Mali. Confederal command, asymmetric national contributions.
- Africa Corps / Wagner-legacy operators — primary external partner, operating across all three AES states. Drone fleets, training cadres, information operations.
- Turkish drone exporters — TB2 Bayraktar systems acquired by AES states; significant tactical effect, not yet strategically decisive.
- MINUSMA — withdrawn (2023). No replacement. The post-MINUSMA security vacuum is the structural condition of the 2026 offensive.
Climate–Conflict Nexus
The Sahel is warming at approximately 1.5 times the global average rate; current trajectories project at least +2°C by 2040 over a baseline that already places the region near the upper bound of human habitability. The mechanisms by which climate stress translates into insurgent advantage are now empirically well established and operate at three levels:
- Livelihood collapse — desertification, erratic rainfall, and the southward retreat of the agro-pastoral frontier degrade the income base of farming and pastoralist communities, making jihadist economic offers (taxation in exchange for protection, zakat, herd protection) competitive with state alternatives.
- Resource conflict — pastoralist–farmer disputes over land and water, historically managed through customary mechanisms, are increasingly arbitrated by armed actors on both sides. JNIM has operationalised this systematically by inserting itself as a Fulani-protector force in central Mali and Burkina Faso.
- Forced displacement — the central Sahel now hosts approximately 8 million internally displaced persons; food insecurity in 2023 reached catastrophic hunger for ~45,000 people on IPC Phase 5. Displacement strips state institutions of population legitimacy and concentrates recruitment pools in peri-urban margins.
The Lake Chad Basin presents the same mechanisms in concentrated form: lake recession, fisheries collapse, and Boko Haram / ISWAP exploitation of the climate-displacement-recruitment loop. Morocco’s May 2026 call to the African Union Peace and Security Council to integrate climate into national security and counter-terrorism strategies acknowledges the analytical reality but lacks an implementation vector.
Migration and the Mediterranean
Sahelian displacement does not stay regional. The collapse of EU–AES cooperation after 2023 — particularly the disabling of EU border-management partnerships in Niger — has opened the central Mediterranean migration corridor in a new way. Sahelian, Sudanese, and Horn-of-Africa migrants traverse Libya in volumes that the post-Gaddafi militia ecosystem now monetises through smuggling, extortion and trafficking. Russia’s Libyan footprint, integrated with Africa Corps’ Sahelian footprint, gives Moscow a structural lever over European migration flows.
Western Strategy Collapse
The Western counter-terrorism architecture in the Sahel — Operation Serval (2013), Operation Barkhane (2014–22), the G5 Sahel Joint Force, the Takuba Task Force, EU training missions, MINUSMA — has been disassembled. France’s Sahel posture is residual. The US AFRICOM withdrawal from Niger (2024) closed the last drone hub. The EU has no operational counter-terrorism presence in any AES state. ECOWAS has been bypassed by the AES departure and no longer provides a regional security envelope. There is no replacement architecture.
The strategic implication is that the central Sahel insurgent system is now developing without external counter-pressure beyond what Russian / Africa Corps assets can supply — and those assets, on April–May 2026 evidence, are insufficient.
Strategic Implications
- The AES is a political success and a security failure. As a sovereigntist project, it has consolidated three juntas, captured the regional narrative, and detached the Sahel from Western influence. As a counter-insurgency project, it is empirically losing.
- Spillover is now the central second-order risk. The expansion of JNIM and ISSP into the Gulf of Guinea littoral states — Togo, Benin, Côte d’Ivoire, Ghana — is documented and accelerating. Nigeria’s northern theatre and the Lake Chad Basin amplify the dynamic.
- The Russian footprint is locked in but not load-bearing. Africa Corps cannot deliver decisive results, but the AES political dependence on Russia precludes diversification. The juntas need Moscow more than Moscow needs them.
- Climate is now a strategic actor. Any counter-insurgency framework that does not incorporate climate adaptation, livelihood resilience, and pastoralist-farmer conflict mediation will fail on a multi-year horizon, regardless of military performance.
Escalation Scenarios (12-month horizon)
Scenario A — JNIM consolidates Mali, AES holds the capitals (assessed: most likely). JNIM and FLA expand rural control across central and northern Mali but cannot take or hold Bamako. The AES retains the capitals, expands the joint force toward 25,000, and accepts a strategic stalemate in which the state controls cities and arteries while insurgents control the countryside. Spillover into littoral states accelerates. Probability: ~50%.
Scenario B — Coastal state crisis (assessed: plausible). A major JNIM or ISSP attack inside Togo, Benin or Côte d’Ivoire triggers a coastal counter-insurgency campaign with US or French support. The Sahel war becomes a West African war. ECOWAS is partially reactivated as a security organ. Probability: ~25%.
Scenario C — AES capital fall or junta collapse (assessed: tail risk but rising). A repeat of the April 2026 strike pattern succeeds in decapitating one of the three juntas, or a successful insurgent campaign forces the loss of a regional capital (Mopti, Ouahigouya, Tillabéri). Russia is unable to stabilise. The AES political project fractures. Probability: ~20%. Residual ~5% for low-probability disruptors (mass humanitarian collapse triggering external R2P intervention; a JNIM strategic split; Mauritanian destabilisation).
Indicators to Watch
