The relentless spread of extremist groups across the Sahel region presents a profoundly destabilizing force, currently displacing over 4.1 million people and fueling a humanitarian crisis that demands immediate, coordinated action. This escalating insecurity directly challenges established alliances, exacerbates existing geopolitical competition, and threatens regional trade routes vital to the economies of Europe and Africa. Understanding the complex dynamics of the ‘G5’ – Burkina Faso, Mali, Niger, Chad, and Mauritania – is now critical to safeguarding global security.
A critical indicator of this shifting landscape can be found in the recent surge in coordinated attacks by groups like Jama’at Nasr al-Islam wal-Muslimin (JNIM) and the Islamic State in the Greater Sahara (ISGS). According to a January 2026 report by the International Crisis Group, “The absence of effective governance, combined with a desperate lack of economic opportunity, has created a breeding ground for radicalized youth, profoundly increasing the vulnerability of these nations.” This vulnerability is not new; the roots of the current crisis are deeply embedded in decades of instability, including the 1960 independence of the countries from France, the subsequent interventions of various foreign powers (most notably the United States and Russia), and the ongoing legacy of conflict within the region.
## The Genesis of Instability: A Complex History
The Sahel’s instability is a multifaceted problem with origins dating back to colonial boundaries and the imposition of centralized states. The French colonial administration, which governed much of the region, created arbitrary borders that disregarded ethnic and tribal affiliations, fostering future conflict. Following independence, many of these nations experienced coups and civil wars, often fueled by external support for competing factions. The collapse of Libya in 2011 further destabilized the region, leading to an influx of weapons and the rise of extremist groups. Notably, the 2012 crisis in Mali, triggered by a Tuareg rebellion, quickly spiraled into a full-scale insurgency with international involvement, including French military intervention. This intervention, while initially successful in pushing back the rebellion, ultimately failed to address the underlying drivers of instability. “The Mali intervention demonstrated a critical miscalculation: military force alone cannot resolve a crisis rooted in socioeconomic inequality and weak governance,” notes Dr. Fatima Diallo, a Senior Research Fellow at the Institute for Strategic Studies, in a recent analysis.
The arrival of Russian mercenaries, particularly the Wagner Group, further complicated the situation. Initially contracted by Mali to assist in counterterrorism efforts, their presence quickly became associated with human rights abuses and a deepening authoritarianism. This development significantly impacted the dynamics within the ‘G5’ and pushed many nations towards an increasingly fraught relationship with Western partners.
## The ‘G5’ – A Nexus of Vulnerability
The ‘G5’ nations share a geographically contiguous border area, a significant portion of which is characterized by porous borders, sparsely populated areas, and a lack of infrastructure. This creates a highly permissive environment for extremist groups to operate and move freely. The region’s economy is largely dependent on agriculture, and climate change – including prolonged droughts and desertification – is exacerbating existing vulnerabilities and driving populations towards displacement and economic hardship. “The environmental pressures are not simply exacerbating existing problems, they are actively creating new ones, transforming localized conflicts into broader humanitarian crises,” argues Professor Jean-Luc Dubois, a specialist in African security at the Sorbonne University.
Data from the United Nations shows that the ‘G5’ have seen a dramatic increase in violent extremist incidents over the past six months, with JNIM and ISGS conducting coordinated attacks on military installations, government buildings, and civilian populations. These attacks have weakened state authority and created a power vacuum, further fueling the recruitment of young people into extremist groups.
## Recent Developments and Strategic Shifts
Over the past six months, the situation in the ‘G5’ has deteriorated significantly. The military coups in Mali and Niger, initially presented as efforts to restore stability, have further isolated these nations and increased the influence of Russia. Niger’s recent expulsion of US and French military personnel, following a coup led by General Abdourahamane Tchiani, represents a pivotal moment. This action has triggered a scramble among international actors, with China, Russia, and the United Arab Emirates vying for influence. The European Union's attempts to provide assistance through military aid and security training have been hampered by political tensions and concerns about human rights. Moreover, the rise of the Azawad Self-Defense Group in northern Mali, backed by elements within the Malian military, has significantly expanded the theatre of conflict.
Looking ahead, the next six months are likely to see a further intensification of violence in the ‘G5’ as extremist groups consolidate their gains and seek to expand their territorial control. The long-term (5-10 year) outcome hinges on several critical factors, including the ability of the international community to develop a coordinated approach, the willingness of regional governments to address the underlying drivers of instability, and the capacity of local communities to resist extremist influence. Failure to do so could result in the complete collapse of state authority, the establishment of ungoverned spaces, and the further spread of extremist ideology.
## A Call for Strategic Reflection
The situation in the Sahel is a stark reminder that security interventions must be holistic and address the root causes of conflict. A continued reliance on military force alone will not solve the problem. A strategic reassessment of alliances, combined with targeted development assistance and a commitment to promoting good governance, are urgently needed. The challenge lies in fostering a collaborative environment where nations can address their shared vulnerabilities and work together to safeguard regional stability. The question is not whether we can prevent further descent into chaos, but whether we possess the collective will to act decisively. Let the shifting sands of the Sahel serve as a constant call for strategic reflection and renewed commitment.
