Lake Chad Basin Insurgency
Nigeria's 2025 death toll surpassed its 2014 Boko Haram peak as a joint U.S.-Nigeria strike killed ISWAP's IS global liaison.
Nigeria is fighting four wars at once.
In the northeast, the Islamic State West Africa Province (ISWAP) and the remnants of Boko Haram run a jihadist insurgency that began in 2009, when security forces killed Boko Haram's founder in custody and his successor relaunched the movement as an armed campaign. In the northwest, bandit militias raid villages and run mass kidnappings. Across the Middle Belt, Fulani herders and farming communities kill each other over land. In the Niger Delta, militants sabotage oil infrastructure.
The Nigerian Armed Forces face all four fronts with a single, overstretched military, and the country's collapse would destabilize a region of 230 million people already pressed by Sahel jihadism to the north.
Trajectory
The May 15 joint U.S.-Nigeria strike killing Abu-Bilal al-Minuki, the Islamic State's assessed global No. 2 and head of its General Directorate of Provinces, is the highest-value counterterrorism action in Nigeria's insurgency history and confirms a shift from U.S. advisory posture to offensive ground participation.
A follow-on strike on May 18 killed 20 additional IS members.

Analysis
ISWAP's shura-based command structure has absorbed repeated leadership losses, including al-Barnawi's reported 2023 death and now al-Minuki's killing, without operational disruption.
Nigeria's 2025 death toll of roughly 12,000 surpassing the 2014 Boko Haram peak and exceeding Iraq, Syria, and Yemen combined is the most consequential single data point in the conflict's recent trajectory.
Lakurawa's consolidation in Sokoto and Kebbi represents a qualitative shift from banditry to parallel governance.
Historical Context
Mohammed Yusuf founds Boko Haram in Maiduguri, preaching that Western education and secular governance are forbidden under Islam, drawing thousands of followers across Nigeria's impoverished northeast.
Nigerian security forces crush a Boko Haram uprising in Maiduguri, killing founder Mohammed Yusuf in custody; his successor Abubakar Shekau relaunches the group as a full armed insurgency targeting police, military, and civilians.
Boko Haram kidnaps 276 schoolgirls from Chibok, sparking the global #BringBackOurGirls campaign; the group also seizes territory across Borno State, briefly declaring a caliphate in Gwoza.
A Multinational Joint Task Force of Nigerian, Chadian, Nigerien, and Cameroonian troops pushes Boko Haram out of most held territory, but the group shifts to suicide bombings and guerrilla raids killing thousands annually.
A faction splits from Boko Haram to form ISWAP, formally affiliating with Islamic State; ISWAP adopts a strategy of targeted military attacks and limited civilian governance, making it more resilient and eventually dominant in the Lake Chad basin.
Shekau dies during a confrontation with ISWAP forces; most remaining Boko Haram fighters are absorbed into ISWAP, consolidating jihadist command across the northeast while the Nigerian military suffers repeated ambushes with heavy casualties.
Simultaneously, bandit militias terrorize northwest Nigeria and Fulani-farmer violence escalates across the Middle Belt, killing thousands annually and displacing millions, stretching Nigerian security forces across multiple unconnected fronts.
LIMITED EXTERNAL: US (intelligence, training), UK (advisory). Boko Haram/ISWAP: No major state sponsor but ISWAP receives IS guidance. Niger (now hostile) and Chad historically allowed cross-border operations.
