Cause

Following the U.S. invasion of Afghanistan in 2001 and Pakistan's alignment with the U.S.-led war on terror under President Pervez Musharraf, Al-Qaeda and Taliban fighters crossed into Pakistan's Federally Administered Tribal Areas. Tensions escalated when the Pakistan Army began operations in Waziristan to root out Al-Qaeda fighters, drawing armed resistance from entrenched militant networks along the mountainous border regions.

Event

Beginning in 2004, Pakistani forces engaged in sustained armed conflict against Islamist militant groups including the TTP, Al-Qaeda, Jundallah, and allied Central Asian organizations across Khyber Pakhtunkhwa and FATA. The Lal Masjid siege in Islamabad intensified hostilities, prompting the TTP to launch widespread suicide bombing campaigns. Operations such as Zarb-e-Azb eventually cleared TTP territorial holdings within Pakistan, transitioning the conflict from conventional war to insurgency by 2017.

Consequence

Pakistani military operations displaced the TTP into Afghanistan, from where it continued cross-border attacks, especially after the Taliban's return to power in August 2021. Pakistan fenced its 2,600 km border with Afghanistan and merged FATA into Khyber Pakhtunkhwa in 2018. The International Crisis Group declared Pakistan in January 2026 as the country most adversely affected by the fall of Kabul, reflecting the conflict's unresolved and intensifying nature.
