Al Qaeda 25 Years After 9/11: A Resilient but Diminished Threat
By Drooid · · How we work
Core Landscape
Twenty-five years after the September 11 2001 attacks, al Qaeda no longer commands the global profile it once held, yet its regional affiliates remain active across Africa and Asia. The group’s central leadership has been weakened—its founder Osama bin Laden was killed in May 2011 and successor Ayman al-Zawahiri in July 2022—but offshoots such as al-Shabaab (Somalia), Jama’at Nusrat al-Islam wal-Muslimin (JNIM, Sahel) and al-Qaeda in the Arabian Peninsula (AQAP) continue to operate.
Background & Context
The 9/11 attacks prompted a worldwide “War on Terror” that reshaped security policy and led to the removal of al Qaeda’s sanctuaries in Afghanistan. Over the past two decades, the United States and its allies have reallocated resources toward great-power competition, leaving counter-terrorism expertise to erode. Scholars note that the movement’s “internal resilience” allows it to exploit seams between conflicts and shifting strategic interests.
Data & Statistics
- The Office of the Director of National Intelligence estimates al Qaeda’s global manpower at 15,000–28,000 fighters.
- UN monitors reported a $50 million ransom paid to JNIM that was shared with AQIM, AQAP, and senior al Qaeda leadership in South Asia.
- In June 2026, JNIM claimed responsibility for an attack on Niamey’s international airport in Niger.
Official Statements & Responses
Gonzalo de Salazar Serrantes, deputy director-general for sanctions at Spain’s Ministry of Foreign Affairs, emphasized the need for coordinated sanctions against terrorist financing.
U.S. Treasury actions in late August 2026 removed former preacher Abdullah al-Muhaysini and the Nusra Front from the Specially Designated Nationals list, reflecting a policy shift toward Syria.
Criticism & Opposition
Analysts warn that budget cuts and personnel losses undermine counter-terrorism capacity. Aaron Y. Zelin, researcher at the Washington Institute, called the erosion of “institutional lessons learned from 9/11” an “irony” that raises the risk of surprise attacks.
On-the-Ground Reports
Regional affiliates have adapted to local conditions. In the Sahel, JNIM leverages ethnic and social conflicts, while al-Shabaab exploits clan rivalries in Somalia. Experts describe a shift from “spectacular attacks on distant enemies” to “localized, grassroots actions” that embed jihadist groups within communities through kidnappings and smuggling.
Conflicting Reports & Gaps
Estimates of al Qaeda’s fighter strength vary widely (15,000–28,000).

What’s Next
The El Cano Forum on Global Terrorism will convene experts on September 24, 2026 to assess evolving jihadist trends. A PBS Frontline documentary, *The Man Who Knew*, aired on September 8, 2026, revisiting early FBI warnings about al Qaeda. These events signal continued scholarly and policy interest in monitoring the organization’s residual capabilities.
