West Africa at the Time of Strategic Recalibration: ECOWAS Regional Force, American Diplomacy, and Jihadist Persistence in the Sahel

The formal reactivation of the ECOWAS Standby Force (ESF) in February 2026, followed by the approval by the chiefs of staff gathered in Sierra Leone of an initial deployment plan of 2,000 soldiers by the end of the year, marks a major institutional turning point in West Africa's security response. This decision comes in a context of accelerated deterioration: armed groups affiliated with al-Qaeda and the Islamic State have expanded their territorial grip from Mali to Nigeria, and some factions are now using increasingly sophisticated weaponry, including modified commercial drones for precision strikes.

The conceptual transformation of the ESF — from a standby force to a rapid intervention capability — represents the most significant change in the 2026 plan. The previous setup had mobilization timelines that were incompatible with the nature of contemporary threats. On December 7, 2025, during a joint exercise, ECOWAS tested faster triggering procedures, signaling its willingness to reform a regional security architecture that has remained largely theoretical since the official creation of the force in 1999.

However, this ambition faces two major structural obstacles. The first is financial: ECOWAS member states struggle to meet their contributions to the collective budget, and external funding sources are drying up in a context of post-Barkhane geopolitical fatigue. The second is political: since January 2025, Mali, Burkina Faso, and Niger have officially withdrawn from ECOWAS to form the Alliance of Sahel States (AES), leaving an operational void precisely in the areas most affected by the jihadist threat.

It is in this fractured context that American diplomacy is making its own realignment. The Trump administration has engaged since early 2026 in a pragmatic rapprochement with the AES juntas, motivated by a dual logic: to reestablish counter-terrorism access in a strategically vital sub-region and to secure supplies of critical minerals. In March, Under Secretary of State Nick Checker made his second Sahel tour in a month, visiting Ouagadougou, Niamey, and Bamako in succession. Washington is also reportedly in the final stages of negotiating a intelligence-sharing agreement with Mali, including the restoration of American operations in Malian airspace.

This rapprochement has been accompanied by a strong symbolic gesture: the lifting in February 2026 of sanctions targeting the Malian Minister of Defense and several senior officials accused of maintaining ties with Russian mercenaries. This decision has drawn criticism in Congress, notably from Democratic Senator Cory Booker during the confirmation hearings of Frank Garcia for the position of Under Secretary of State for African Affairs. It illustrates the prioritization of the current administration's priorities: operational access takes precedence over democratic conditionalities.

On the ground, the security situation continues to deteriorate at a concerning pace. In January 2026, a group affiliated with the Islamic State in the Greater Sahara (EIGS) launched a bold attack on the international airbase in Niamey, forcing Nigerien authorities to strengthen security perimeters around the capital. Even more significant: since September 2025, a faction linked to the Group for Support of Islam and Muslims (JNIM) has maintained a blockade on fuel supplies to Bamako, paralyzing transport and essential services in a capital housing nearly 2.7 million inhabitants.

The increasing use of modified commercial drones by Sahelian armed groups represents a major tactical evolution documented since early 2026. These devices, often modified quadcopters designed to drop grenades or improvised explosive devices, allow insurgents to strike logistical convoys and military posts with newfound precision and impunity. Regular armed forces struggle to develop effective countermeasures due to a lack of suitable and affordable anti-drone equipment.

The pressure is now extending to coastal states. Togo and Benin are experiencing a significant resurgence of armed incursions from their northern borders with Burkina Faso. Benin, in particular, has suffered several attacks in the Pendjari and W parks since late 2025, threatening a major ecological and tourist interest area. For these countries, the issue is no longer preventive but immediate: the question is no longer whether the jihadist phenomenon will reach their territories, but how to contain an expansion that has already begun.

In light of all these dynamics, researcher Beverly Ochieng from Control Risks aptly summarizes the central challenge: any purely military response is doomed to fail if not accompanied by social interventions targeting the recruitment vectors of armed groups. The security architecture taking shape in 2026, between the ECOWAS regional force, American re-engagement, and the resistance of AES states, remains deeply fragmented. In the Sahel, strategic coherence remains the rarest resource.
