The Southern Advance: How Governance Failures and Neo-Colonial Legacies Are Fueling West Africa's Expanding Insurgency

The Unfolding Crisis: From Sahel to the Coast

For over a decade, the Sahel region has been the epicenter of global terrorist violence, accounting for more than half of such deaths worldwide. What began in northern Mali in 2012 has evolved into a complex regional conflict system involving groups like Jama’at Nusrat al‑Islam wal‑Muslimin (JNIM) and the Islamic State in the Sahel, alongside local militias and criminal networks across Mali, Burkina Faso, Niger, Chad, and northern Nigeria. The grim reality, as detailed in recent analysis, is that this crisis is no longer contained. It is steadily advancing toward the Gulf of Guinea, with coastal states like Benin, Togo, and Ghana now on the frontline.

This expansion is not characterized by large-scale, conventional invasions. Instead, it follows a pattern of gradual penetration. Militant groups are probing the northern peripheries of coastal states, launching cross-border attacks from eastern Burkina Faso and southwestern Niger into northern Benin and Togo’s Savanes region. Incidents have increased sharply since 2022. More alarmingly, these groups are embedding within communities, building supply networks, and establishing logistical rear bases, as seen in northern Ghana. Their strategy mirrors their evolution in the Sahel: a shift from classic terrorism towards a hybrid insurgency that seeks to control territory, regulate local economies, and establish parallel governance structures where the state is weak or absent.

The Anatomy of Expansion: Gaps, Grievances, and Networks

The technical drivers of this expansion are multifaceted. Militant networks are deeply intertwined with organized crime, utilizing smuggling routes that link West Africa to North Africa for revenue and logistics. They are also evolving technologically, experimenting with drones and encrypted communications. Crucially, they exploit specific structural vulnerabilities. Northern border regions of coastal states often suffer from chronic underdevelopment, limited state presence, and concentrated economic opportunity in southern urban centers. These governance deficits create fertile ground for recruitment.

Local tensions, such as those between farmers and pastoralist communities, particularly among Fulani herders, have intensified. Groups like JNIM deliberately exploit these frictions, positioning themselves as protectors of marginalized groups. Furthermore, security responses have sometimes backfired; community militias mobilized to fight extremists have been accused of targeting Fulani civilians, reinforcing cycles of grievance and retaliation that militants eagerly harness. The situation is becoming increasingly regional and interconnected, with the Benin-Niger-Nigeria border triangle acting as a convergence zone for Sahel-based extremists, Nigerian militant groups, and criminal bandit networks.

Beyond the ‘Spillover’ Narrative: A Crisis of Structural Abandonment

To label this a mere ‘spillover’ of Sahelian violence is to profoundly misunderstand its roots. This is not an external pathogen infecting healthy tissue; it is a systemic failure metastasizing across a body politic long weakened by historical and contemporary injustices. The so-called ‘governance gaps’ exploited by militant groups are not accidental voids. They are the direct legacy of colonial borders that carved up ethnic and economic zones, and of neo-colonial economic systems that prioritized resource extraction from the Global South over holistic, equitable development for its people.

For decades, international financial institutions, often dominated by Western interests, imposed structural adjustment programs that gutted public services and state capacity in these very regions. The result is the predictable landscape we see today: northern territories neglected by central governments, where the promise of the post-colonial state has failed to materialize. When a militant group arrives offering a crude form of dispute resolution or predictable taxation—however coercive—it fills a vacuum created by this systemic abandonment. The West’s sudden concern over “major trade routes, ports, and energy infrastructure along the Atlantic coast” reveals the true priority: not human security, but the protection of capital and extraction channels. Where was this urgency when these border regions needed schools, hospitals, roads, and justice?

The False Panacea of Militarization and the Path Forward

The instinctive response from Western capitals and some regional governments will be a surge in militarization—more weapons, more foreign troops, more drone strikes. The Sahel itself is a graveyard testament to the failure of this approach. While military force is necessary to contain immediate threats, it is utterly insufficient to address the underlying drivers. In fact, security operations without accountability, oversight, and a parallel commitment to justice often deepen the very grievances that fuel insurgency. Communities will not trust authorities who cannot protect them from abuse, whether from militants or from their own security forces.

The solution must be as structural as the problem. First, it requires a radical re-prioritization of resources by coastal West African governments towards their marginalized northern regions. Investment must flow not just to army barracks, but to courts, schools, clinics, and economic opportunities that offer a legitimate alternative to the conflict economy. This is a matter of national sovereignty and social justice, not donor appeal.

Second, regional cooperation is essential but must be sovereign and African-led. Intelligence-sharing and joint patrols are necessary, but they must operate within frameworks that respect human rights and are accountable to civilian institutions. The model cannot be the failed Western-led missions of the Sahel, which often operated with impunity and lacked local legitimacy.

Third, the role of international partners must be fundamentally reconceived. The United Nations and other bodies must prioritize strengthening institutions—judicial capacity, anti‑corruption bodies, accountable security sector reform—over simply writing checks for military hardware. The decades of pouring arms into the Sahel while underfunding governance have produced the catastrophe we see today. To repeat that mistake in coastal West Africa would be criminal negligence.

A Sovereign Future or a Deepening Quagmire?

Benin and Togo now stand at a crossroads. They can become the next theater of a widening insurgency, locked in a forever war that drains their youth and resources, or they can become the place where the tide begins to turn. The choice is stark. Adopting a solely security-centric approach, often designed and funded by external powers with their own interests, will lead down the first path. It perpetuates the neo-colonial dynamic where the Global South remains a battlefield for proxy conflicts and security contracts, its stability secondary to external strategic and economic interests.

The second path requires immense courage and vision. It demands a break from models that have failed elsewhere. It requires centering the needs of the most vulnerable communities, delivering real justice and development, and building a social contract based on trust and accountability. This is not a soft option; it is the only durable one. It is the path of true sovereignty, where African nations address their challenges with solutions rooted in their own contexts, rejecting the one-size-fits-all prescriptions that have fueled instability from Libya to Mali.

The expansion of violence toward the Gulf of Guinea is a chilling alarm bell. It signals the consequences of a world order that has consistently undervalued the lives and potential of people in the Global South. The response will reveal whether we have learned anything from the ashes of the Sahel. Will we see more of the same failed policies, dressed in new jargon? Or will there be a genuine, humble turn towards addressing the root causes—the poverty, the injustice, the legacy of exploitation—that create the conditions for extremism to thrive? The people of coastal West Africa deserve a future of peace and self-determination, not a destiny as the next chapter in a never-ending manual of imperial blowback.
