The Threat of Al Qaeda and ISIS-K in Taliban-Controlled Afghanistan

A year and a half before their takeover of Afghanistan in August, the Taliban signed a deal with the U.S. stipulating that they would not allow any individuals or groups to use Afghan soil “to threaten the security of the United States and its allies.”
Today, with the Taliban in control and U.S. troops withdrawn after two decades of war and insurgency — a moment that FRONTLINE correspondent Najibullah Quraishi examined in the October 2021 documentary Taliban Takeover — those concerns remain. On Oct. 26, a top Pentagon official said terrorist groups in Afghanistan could be capable of launching attacks on the West and its allies within six months to two years.
