Why Are Pakistan and Afghanistan at War?

Why It Matters

The conflict jeopardizes regional stability and could spark a wider South‑Asian war, disrupting trade, displacing millions and reshaping geopolitical alliances.

Key Takeaways

• Pakistan declared open war on Afghanistan in February 2026.
• TTP attacks killed over 2,000 Pakistani civilians in 2024.
• Afghanistan's Taliban refuses to curb TTP, fueling cross‑border violence.
• Border's Durand Line remains porous, enabling militants and smugglers.
• Pakistan hints at regime change, risking broader regional conflict.

Summary

Pakistan announced an open war against Afghanistan in February 2026, marking a dramatic reversal of a historically close relationship. The conflict stems from Islamabad’s accusation that Kabul’s Taliban government shelters the Tehrik‑i‑Taliban Pakistan (TTP), which has unleashed a wave of attacks inside Pakistan.

In 2024 alone, TTP‑linked assaults killed at least 2,000 Pakistani civilians and triggered 521 terrorist incidents—a 70 % rise from the previous year. The porous Durand Line, long‑standing autonomy in Pakistan’s former FATA region, has allowed militants, smugglers and refugees to move freely, turning the border into a jihadist sanctuary after the 2001 U.S. invasion.

Despite hopes that the Taliban’s 2021 return to power would curb cross‑border terrorism, violence has escalated. A senior Pakistani official warned, “If any government sponsors the outlaws and killers of innocents, they have become outlaws and murderers themselves,” underscoring Islamabad’s frustration with Kabul’s perceived inaction.

The war threatens to destabilize South‑Asia, drawing in regional powers and jeopardizing trade routes. Pakistan’s hinted intent to topple the Taliban could trigger a broader confrontation, raising the stakes for global security and humanitarian aid efforts.

Original Description

It’s a striking turn for two countries that used to be close—Pakistan once aided and sheltered the Afghan Taliban, the very government it's waging war against.
