Sahel: The JNIM Offensive Reveals the Fragilities of the Sahel States Alliance

The coordinated offensive led by the Group for Support of Islam and Muslims (JNIM) in February and March 2026 marks a major strategic turning point in the security dynamics of the Sahel. This unprecedented campaign, which mobilized over thirty attacks concentrated mainly in Burkina Faso, demonstrated the persistent capability of jihadist groups to destabilize the region despite the military consolidation efforts undertaken by the Alliance of Sahel States.

Between February 21 and March 6, 2026, the JNIM orchestrated a series of assaults that claimed the lives of more than 120 members of the Burkinabè defense forces, including regular soldiers, forest guards, and members of the Volunteers for the Defense of the Homeland. This operational intensity marks a concerning tactical evolution: the JNIM's adoption of mass violence methods traditionally associated with the Islamic State in the Sahel province, its rival in the region. The Al-Qaeda-affiliated organization thus appears to be adapting its doctrine to maximize the psychological impact of its operations, simultaneously targeting state authority and public trust.

The military response of the AES manifested through several notable counter-offensives. In Mali, the army announced on February 7, 2026, that it had conducted three airstrikes that neutralized 35 JNIM fighters in the Ségou region, near the Niger River. This operation illustrates the growing dependence of Sahelian forces on air power to compensate for their ground vulnerabilities against a mobile and dispersed enemy across vast territories.

In Burkina Faso, February 2026 was marked by the recapture of several localities that had been under militant control for seven years. This territorial reconquest, while symbolically significant, raises fundamental questions about the state's ability to maintain a lasting presence in these areas. The recent history of the Sahelian conflict demonstrates that the liberation of territory does not guarantee its long-term security, particularly in regions where state structures have historically been weak.

The attack on January 29, 2026, against the Diori Hamani International Airport in Niamey, the capital of Niger, perhaps represents the most revealing event of the new phase of the conflict. Thirty fighters from the Islamic State in the Sahel province managed to assault the airport and the adjacent Air Base 101, the headquarters of the AES command, using armed drones, light weapons, and mortars. Although the assault did not achieve its full military objectives, its strategic impact is considerable: it demonstrated the vulnerability of critical facilities located in the very heart of the capital.

This bold attack on Niamey fits into a deliberate strategy aimed at challenging the authority of the military juntas in power in regional capitals. Analysts emphasize that the main objective was to undermine the credibility of security forces and test their rapid response capability. By breaching the defenses of the Nigerien capital, the insurgents sent a clear message: despite the intensive counter-terrorism operations deployed across the Sahel, armed groups retain sufficient freedom of action to strike highly symbolic targets.

Institutionally, the AES is attempting to strengthen its collective security architecture. In March 2026, the alliance announced the creation of a regional criminal court specialized in dealing with terrorism, violent extremism, and human rights violations. This initiative reflects a desire to harmonize judicial responses to threats that transcend national borders. However, the effectiveness of such structures will depend on their ability to operate independently and benefit from the effective cooperation of national security apparatuses.

At the same time, the Economic Community of West African States (ECOWAS) activated its own regional force to combat jihadist groups, particularly aiming to protect coastal states like Benin, Togo, and Nigeria from the southward expansion of organizations like the JNIM and the Islamic State in West Africa. However, this initiative faces major logistical obstacles following the withdrawal of Mali, Burkina Faso, and Niger from the organization, effectively creating two competing security architectures in the region.

Geopolitically, March 2026 witnessed an unexpected diplomatic rapprochement between the United States and members of the AES. The U.S. administration is actively exploring the possibility of a intelligence-sharing agreement with Mali, which would allow the deployment of American drones to monitor terrorist networks, including the JNIM. This initiative marks a notable shift in American policy, following several years of tensions resulting from military coups and the rapprochement of Sahelian juntas with Russia.

The visit of State Department spokesperson Nick Checker to Ouagadougou, as part of a tour that also included Mali and Niger, illustrates this desire to reset relations. Washington now seems to favor a pragmatic approach, recognizing that the fight against transnational terrorism requires cooperation with effective regional actors, regardless of their political affiliations or alternative military partnerships.

This American diplomatic opening occurs within a broader context of influence competition in the Sahel. France, the former colonial power that maintained a significant military presence through Operation Barkhane, has gradually lost its strategic grip on the region. Military juntas have systematically questioned the relevance of the French presence, accusing Paris of inefficiency in the anti-terrorism fight. This anti-French rhetoric has facilitated the geopolitical repositioning of the region.

Russia, through the deployment of private military contractors and the provision of military equipment, has gradually filled the strategic void left by the French withdrawal. However, this increased Russian presence has not reversed the deteriorating security trend. Terrorist groups have continued to expand their territorial influence, suggesting that changing international partners does not in itself constitute a solution to the structural challenge posed by jihadist insurgency.

The underlying factors of Sahelian instability remain largely unchanged: massive youth unemployment, the devastating effects of climate change on pastoral and agricultural livelihoods, the collapse of state structures in vast rural areas, and historical grievances related to the marginalization of certain communities. The foreign ministers of Nigeria and Ghana recently emphasized during a discussion at Chatham House that the Sahelian conflict cannot be reduced to a simple religious dimension, insisting on the need for more nuanced approaches that address these root causes.

The developments of February and March 2026 confirm that the Sahel has become the most active theater of global terrorist violence. The intensification of operations by the JNIM and the ISGS, despite more than a decade of international and regional military interventions, underscores the failure of exclusively security-based approaches. A sustainable strategy must necessarily integrate dimensions of governance, economic development, and community reconciliation, while maintaining military pressure on terrorist networks.
