The Central Sahel

The Insurgent Transition from Attrition to Governance: JNIM, ISSP, and the Structural Exhaustion of the AES Security Model

Executive summary

The central Sahel has crossed a threshold that the vocabulary of "counter-terrorism" no longer captures. Al-Qaeda's regional affiliate, Jama'at Nusrat al-Islam wal-Muslimin (JNIM), and the Islamic State Sahel Province (ISSP) now hold, between them, more territory than at any point since the 2012 Malian collapse — and JNIM has moved beyond attrition warfare into the deliberate substitution of the state, pairing military pressure with taxation, dispute adjudication, and service provision in the zones it controls. The single most consequential instrument in the theatre is not a battlefield victory but an economic siege: the fuel blockade JNIM imposed on southern Mali from 3 September 2025, during which over 300 fuel tankers inbound from Senegal, Côte d'Ivoire, and Guinea have been destroyed. The three Alliance of Sahel States (AES) governments — Mali, Burkina Faso, Niger — have responded to an existential, expanding threat with a security model built on Russian paramilitary support and the performance of sovereignty, and that model is now visibly failing to hold ground. The August Peace and Security Council of the AU (PSC) update is the occasion for this assessment, not its subject; the subject is a regional order sliding from insurgency toward contested proto statehood.

1. The strategic picture: territory, not incidents

The analytically decisive shift is from tempo to control. For a decade the Sahel was measured in attacks — casualty counts, raid frequencies, displacement spikes. That metric now understates the problem, because the groups have transitioned from raiding the state to replacing it. In Burkina Faso, the Traoré regime exercises effective control over less than half of national territory, the remainder largely under the influence of local JNIM affiliates. In Niger, ISSP controls large stretches along the Mali border and in the southwest. This is not a security problem inside functioning states; it is a competition over which authority governs which populations.

JNIM's method is the more sophisticated of the two. Armed Islamist groups are deliberately targeting civilians to pressure communities into cooperation and using blockades to punish communities perceived as supportive of the military, deliberately disrupting economies through coordinated offensives that block key trade and transport routes to undermine government authority. A group that can strangle a capital's fuel supply for eleven months and administer the territory it holds is not conducting terrorism in the conventional sense — it is conducting state building by siege.

2. The Bamako blockade as the theatre's centre of gravity

The fuel blockade deserves separate treatment because it reframes the entire conflict. JNIM blockaded Bamako's fuel supply in early 2026 and launched coordinated nationwide attacks on Mali in April 2026 alongside Tuareg rebels. The campaign — including a 6 May arson attack on trucks carrying food to the capital — appeared designed to isolate Bamako and disrupt supply chains, reminiscent of the fuel blockade in place since September 2025 that has disrupted access to fuel and essential goods.

The significance is doctrinal. JNIM has identified that the AES states are more vulnerable through their economic arteries than on the battlefield. Landlocked economies dependent on a handful of overland corridors from coastal neighbours can be asphyxiated without a single frontal assault on the capital. This is the insurgent equivalent of a naval blockade against a maritime power — a recognition of where the state is genuinely fragile, and it has proven more effective than years of direct engagement.

3. The AES security model is structurally exhausted

The three juntas came to power promising that sovereign, Russia-partnered forces would succeed where French and UN missions failed. The battlefield record now contradicts the premise. JNIM and its Tuareg allies in the Azawad Liberation Front (FLA) launched another countrywide offensive in July 2026, demonstrating growing capability to project simultaneous, coordinated pressure across Mali. In early July, FLA and JNIM forced a government reinforcement convoy to return to Gao after a complex ambush that destroyed military vehicles, a Russian Mi-24 helicopter, and killed several Malian army and Africa Corps soldiers. When a resupply column to a single base cannot get through without losing a Russian attack helicopter, the model of clearing and holding territory has broken.

The deeper problem is that the AES posture generates the very grievances the insurgent’s harvest. Blockade-and-punish campaigns by both the state and the groups fall on the same rural populations, and abuses attributed to state and allied forces feed recruitment. The security model is not merely underperforming; in places it is counterproductive.

4. The AU–AES rupture: the diplomatic variable that governs everything

The unstated centre of any AU engagement on the Sahel is the estrangement between the Union and the three AES governments. The AU's post-coup posture — suspensions, constitutional-restoration demands — was legally coherent and strategically self-defeating: it pushed the three states toward Moscow and away from continental frameworks precisely as the threat metastasised. The AU now finds itself with minimal presence in the theatre where the continent's most acute security emergency is concentrated.

This produces the central dilemma. The instruments that defend constitutional order (sanctions, isolation of juntas) and the instruments that could contain territorial jihadism (security cooperation, intelligence-sharing, presence) now pull in opposite directions. The AU cannot maximise both. Every solidarity visit is an attempt to rebuild a channel the earlier posture closed.

5. The spillover is established, not prospective

The containment framing that treats this as a Malian, Burkinabè, or Nigerien problem misreads the trajectory. The opening of new insurgency fronts in Benin and Togo is equally well established. The northern littoral of the Gulf of Guinea reproduces the conditions that incubated the central Sahel crisis: marginal peripheries, contested pastoral corridors, weak state presence. The question is no longer whether the threat crosses into coastal West Africa but how fast, and whether ECOWAS and the AU can act before it consolidates there as it did in the tri-border zone.

Scenario assessment

Most likely — continued erosion under a sovereignty narrative. The AES states retain their capitals and principal garrisons while progressively losing the countryside; JNIM deepens governance in held zones and tightens economic sieges; the AU remains largely external. Slow strategic defeat masked by the rhetoric of sovereign resilience.

Plausible and dangerous — a capital-level crisis. A sustained blockade or a mass-casualty strike against Bamako, Ouagadougou, or Niamey produces a political rupture inside one AES state. Given the juntas' legitimacy rests on the security promise, a visible failure could trigger factional realignment or a further coup — with unpredictable consequences for the Russian partnership.

Least likely — pragmatic AU–AES re-engagement. The AU subordinates the constitutional agenda to counter-terrorism cooperation, rebuilding presence at the cost of doctrinal consistency. The only path that addresses the threat where it lives, and the one least consistent with the AU's institutional reflexes.

Closing note

The Sahel has passed from a counter-insurgency problem to a contest over governance, and the actors best adapted to that contest are currently the insurgents. The AES security model has been tested to exhaustion; the AU's principled isolation of the juntas has left it without leverage over the outcome. Until the continental posture is reconciled with the battlefield reality — a reconciliation that requires choosing between legal consistency and strategic presence — the trajectory favours the groups that have learned to govern.
