U.S.–Taliban Counterterrorism Cooperation After the 2021 Withdrawal
8/13/2026, 1:35:02 AM
Core Event
After the United States completed its military exit from Afghanistan in 2021, the Taliban-led government began working with Washington to counter the Islamic State Khorasan Province (ISKP). The partnership includes intelligence sharing, joint operations, and Taliban arrests or killings of ISKP fighters in exchange for lenient treatment.
Background & Context
In the 1990s the Taliban sheltered al-Qaeda, enabling attacks such as the 1998 embassy bombings and the September 2001 attacks on the United States. After the 2001 invasion, U.S. forces pursued al-Qaeda, culminating in a 2022 drone strike that eliminated leader Ayman al-Zawahiri. By the withdrawal’s end, U.S. officials warned that pulling out troops could spark a resurgence of al-Qaeda.
Post-withdrawal, al-Qaeda’s capacity in Afghanistan has remained limited, with its strongest elements now in Africa. ISKP, however, has expanded attacks across Iran, Pakistan, Russia and Turkey and has sought to inspire plots in Europe and the United States. The Taliban, aiming to preserve legitimacy, has moved to suppress ISKP, arresting members and offering surrender terms.
Timeline
| Period | Development |
|---|---|
| Early 2021 | CIA director warned of a “significant risk” of al-Qaeda resurgence if U.S. forces withdrew. |
| Late 2021 | U.S. completed its withdrawal; Taliban assumed control of the entire country. |
| 2022 | Drone strike killed al-Qaeda leader Ayman al-Zawahiri. |
| 2023-2025 | Taliban repeatedly arrested or killed ISKP operatives; negotiated surrenders for some fighters. |
| 2025-2026 | U.S. intelligence used Taliban-provided information to warn Iran, Russia and European states about pending ISKP attacks. |
Data & Statistics
- ISKP suicide bombing at Kabul International Airport killed 13 U.S. service members and roughly 170 Afghan civilians.
- The 2022 drone strike eliminated al-Qaeda’s top leader; the group has not named a successor.
- ISKP is identified as the primary terrorist threat inside Afghanistan, while al-Qaeda’s most potent cells now operate in Africa.
Official Statements & Responses
- The CIA director warned that the withdrawal would create a “significant risk” of an al-Qaeda resurgence.
- The White House’s counterterrorism chief called the Taliban “moderately cooperative counterterrorism partners,” noting their nationwide intelligence networks enable Washington to alert regional allies about ISKP threats.
- U.S. officials credit Taliban cooperation with disrupting several ISKP-linked plots targeting Iran, Russia and European nations.
Impact and Assessment
The partnership reflects a pragmatic shift: the United States works with a former adversary to contain a more immediate threat. While the Taliban’s governance remains repressive and it continues to harbor al-Qaeda elements, its limited support for ISKP has reduced the group’s capacity for large-scale attacks within Afghanistan. The collaboration allows the United States to leverage Taliban intelligence to pre-empt ISKP operations beyond Afghan borders, contributing to regional security.
Conflicting Reports & Gaps
- Sources agree al-Qaeda’s operational strength in Afghanistan has waned, but differ on the extent of Taliban tolerance for al-Qaeda training activities.
- No publicly available data confirm the exact number of ISKP operatives neutralized through Taliban cooperation, leaving the partnership’s overall effectiveness partially unquantified.
Overall, the five-year experience since the withdrawal suggests that, despite moral and strategic concerns, engaging the Taliban has yielded tangible counterterrorism benefits against ISKP, while the broader al-Qaeda threat continues to shift geographically.
