Nigeria's No Sanctuary Doctrine: Securing Borderlands Through Lawful Force and Regional Cooperation
The persistent threat of armed groups operating across Nigeria's northern and western corridors has revealed critical vulnerabilities in regional security structures. These groups have demonstrated remarkable adaptability, launching attacks within Nigerian territory before withdrawing across international borders to regroup and return with enhanced capabilities. This dangerous pattern has persisted largely because security enforcement has traditionally halted where immediate threats appear to dissipate.
A New Security Standard for Nigeria
President Bola Ahmed Tinubu's administration is establishing a fundamentally different security standard that rejects cross-border sanctuary as an acceptable condition. This position, best described as the "No Sanctuary Doctrine," asserts that any territory used to stage or sustain attacks against Nigeria falls within Nigeria's legitimate operational security concern, subject to existing legal frameworks and international agreements.
The doctrine operates on the principle that sovereignty is exercised not just through territorial control but through the protection of citizens and the denial of operational space to hostile actors. Where threats are transnational in nature, the response must be equally transnational in scope and coordination.
Existing Legal Frameworks and Regional Mechanisms
Nigeria already operates within established lawful structures that enable this proactive approach. The Multinational Joint Task Force, established by the Lake Chad Basin Commission with African Union support, provides for coordinated military operations against terrorist groups across Nigeria, Niger, Chad, and Cameroon. This force's operational design specifically permits cross-border action under agreed command structures and rules of engagement.
Since its reconstitution in 2015, Nigeria has maintained a central leadership role within this regional security mechanism. The challenge has not been the absence of legal authority but rather the need for consistent application and greater clarity about the scope of that authority.
Regional Political Challenges and Strategic Responses
Since 2023, disruptions in regional political order have significantly weakened security coordination. Coups in parts of the Sahel have negatively affected intelligence sharing and joint patrol structures, creating operational gaps that armed groups have exploited to expand their movements across tri-border areas.
Nigeria has absorbed the consequences of these security gaps through increased pressure on border communities and critical trade routes. The Tinubu administration recognizes that security responses cannot depend on the restoration of ideal political conditions but must proceed within frameworks that remain in force.
The administration has reinforced these frameworks through targeted bilateral arrangements, including a memorandum of understanding on defence cooperation concluded with Niger in August 2024. This agreement reflects a standing regional recognition that insecurity in border areas represents a shared threat requiring coordinated action.
ECOWAS Leadership and Continental Engagement
President Tinubu's engagement with the Economic Community of West African States (ECOWAS) demonstrates Nigeria's commitment to regional security leadership. Nigeria has supported the development of a regional standby force for counter-terrorism and restored significant financial commitments to the bloc, including over N169 billion in community levy payments between January 2023 and July 2024.
This leadership has been particularly evident during moments of political tension within the sub-region, including Nigeria's diplomatic and security engagement following the attempted coup in the Benin Republic, which contributed to stabilizing the situation without escalation.
At the continental level, Nigeria has aligned diplomatic efforts with operational capacity building. During the African Union summit in February 2025, Nigeria supported the renewal of the Multinational Joint Task Force mandate and the upgrade of the National Counter Terrorism Centre to a Regional Counter Terrorism Centre. Nigeria also entered into a Strategic Sea Lift Services agreement with the African Union to support peace operations, disaster response, and humanitarian logistics.
International Partnerships and Enhanced Capabilities
This regional approach is reinforced by a comprehensive set of international partnerships aligned with shared security objectives. Engagement with the United States through the Joint Working Group supports intelligence sharing, training, and defence coordination. Cooperation with the United Kingdom includes defence collaboration and the development of customs data exchange systems between the Nigeria Customs Service and HM Revenue and Customs to strengthen border monitoring capabilities.
The Strategic Dialogue Mechanism with Brazil, concluded in June 2025, adds further capacity through defence cooperation in training and intelligence sharing. Together, these partnerships expand Nigeria's capacity to detect, track, and respond to threats before they materialize within its territory while complementing regional security efforts.
Operational Implementation and Future Directions
These engagements support a clearly defined operational objective: to deny armed groups sanctuary around Nigeria's borders. Nigeria will act through the Multinational Joint Task Force, bilateral agreements, and regional mechanisms to ensure that border proximity does not provide protection for armed groups.
Cross-border actions will be coordinated, intelligence-led, and executed within agreed legal frameworks, supported by deeper intelligence integration with neighbouring states. As this approach develops, there is a growing case within ECOWAS for more integrated data systems across member states.
A coordinated framework linking national identity databases, border control systems, and security agencies would enable early identification of persons of interest across jurisdictions and strengthen collective response capacity.
Complementary Domestic Security Measures
This external security posture carries clear operational demands that must be balanced with domestic security challenges. Political conditions in the Sahel remain unstable, and partner states face their own governance pressures. Within Nigeria, sustained internal coordination remains essential.
Efforts to control the proliferation of small arms and light weapons remain particularly critical, especially in addressing the role of illicit arms flows and local manufacturing networks that sustain non-state actors. Strengthening existing institutions responsible for arms control, alongside greater accountability within border communities affected by cross-border insurgent activity, will complement external security efforts and reinforce national stability.
Conclusion: A Measurable Standard for Security Policy
The No Sanctuary Doctrine establishes a measurable standard for security policy execution that removes ambiguity from Nigeria's response to cross-border insecurity. It affirms that territorial defence includes the denial of external staging grounds for attacks and places Nigeria in its established role as the principal security actor within its immediate region.
President Tinubu has set this strategic direction, with the National Assembly, regional partners, and Nigeria's security institutions participating in its execution. The results will ultimately determine the stability of Nigeria's borderlands and the credibility of the state's most basic responsibility: the protection of its citizens from transnational security threats.
