Pakistan-Afghanistan Relations

Pakistan-Afghanistan relations have deteriorated sharply over the years over multiple flashpoints. Read here to know about the history of the relations and recent clashes across the Durand Line.

For the second time in six months, Pakistan-Afghanistan have engaged in intense cross-border military clashes, signalling a sharp deterioration in political, military and societal ties across the Durand Line.

Unlike earlier skirmishes during the US presence in Afghanistan, the recent confrontations involve deep air and missile strikes, retaliatory cross-border attacks, and heavy casualties, pointing to a structural rupture in what was once described as Pakistan’s “strategic depth” policy.

The Durand Line and Historical Tensions

The Durand Line, drawn in 1893 between British India and Afghanistan, remains a contested boundary. While Pakistan treats it as an international border, successive Afghan governments, including the Taliban, have refused formal recognition.

Historically, Pakistan cultivated influence in Afghanistan to:

• Counter Indian presence
• Ensure a friendly regime in Kabul
• Maintain strategic depth against India

This policy crystallised during Pakistan’s support for the Taliban in the 1990s and continued, covertly and overtly, through the US-led intervention period.

Pakistan-Afghanistan Clashes: Immediate Trigger

The central flashpoint in the current crisis is the Tehrik-i-Taliban Pakistan (TTP).

What is TTP?

• Formed in 2007
• Seeks to overthrow the Pakistani state
• Ideologically aligned but organisationally distinct from the Afghan Taliban

Pakistan’s Allegation:

Islamabad accuses Kabul of:

• Providing safe havens to TTP fighters
• Allowing cross-border infiltration
• Refusing to act decisively against anti-Pakistan militants

Since the Taliban takeover in August 2021, TTP attacks inside Pakistan have significantly increased, targeting military posts and civilians.

Why Is Pakistan Turning Against the Taliban?

Strategic Blowback: Pakistan’s long-standing policy of nurturing Islamist militant groups as instruments of foreign policy has resulted in reverse spillover. The Afghan Taliban’s victory has emboldened the TTP.

Collapsing Leverage: Islamabad assumed that the Taliban regime would remain dependent and compliant. However:

• The Taliban seeks autonomy in foreign policy.
• It resists acting solely as a proxy.
• It is unwilling to antagonise ideologically aligned groups like the TTP.

Domestic Security Crisis: Rising militant violence inside Pakistan has created pressure on the military establishment to demonstrate control and deterrence.

Thus, Pakistan’s recent air and missile strikes deep inside Afghan territory signal frustration and a willingness to escalate.

Why Has the Taliban Turned Against Pakistan?

• Sovereignty Assertion: The Taliban regime seeks legitimacy as an independent state actor. Subordination to Pakistan undermines its domestic credibility.
• Durand Line Dispute: The Taliban has opposed Pakistani fencing along the Durand Line, seeing it as unilateral border enforcement.
• Ideological and Tribal Dynamics: Pashtun solidarity across the border complicates Kabul’s willingness to suppress TTP militants, who share ethnic and ideological ties.

Recent Escalation in 2026

The latest phase includes:

• Pakistani air and missile strikes in Kabul and Kandahar
• Taliban retaliatory attacks on Pakistani military posts
• Civilian and military casualties
• Collapse of a ceasefire mediated by Turkiye and Qatar

Pakistan’s Defence Minister’s declaration of an “open war” marks a dramatic escalation in rhetoric.

Strategic Implications

End of “Strategic Depth” Doctrine: Pakistan’s Afghanistan policy appears to have backfired, transforming a supposed asset into a security liability.

Regional Instability: Escalation risks:

• Refugee flows
• Cross-border insurgency
• Militant spillover into Central and South Asia

Weak State vs. Isolated Regime

• Pakistan faces an economic crisis and internal instability.
• Afghanistan remains diplomatically isolated and economically fragile.

An unequal battlefield may produce prolonged low-intensity conflict rather than decisive outcomes.

Implications for India

• Reduced Pakistan-Taliban cohesion may alter regional security calculations.
• However, instability in Afghanistan risks strengthening transnational extremist networks.
• India must monitor potential refugee and radicalisation spillovers.

Pakistan-Afghanistan Relations: Timeline (1990s-2026)

The relationship between Pakistan and the Taliban has evolved from strategic patronage to strained confrontation. Below is a structured chronological timeline capturing key phases.

1990-1994: Post-Soviet Chaos and Strategic Calculus

• After the Soviet withdrawal (1989) and the collapse of the Najibullah government (1992), Afghanistan descended into civil war.
• Pakistan’s military establishment sought a friendly regime in Kabul to ensure strategic depth against India.
• Emergence of the Taliban movement among Pashtun religious students in Kandahar (1994).

1994-1996: Rise of the Taliban

• Pakistan’s security establishment, particularly elements within the ISI, reportedly provided logistical and strategic support.
• 1996: Taliban captured Kabul and established the Islamic Emirate of Afghanistan.
• Pakistan became one of only three countries (along with Saudi Arabia and the United Arab Emirates) to officially recognise the Taliban regime.

1996-2001: Strategic Partnership Phase

• Close alignment between Islamabad and the Taliban regime.
• Afghanistan served as a rear base for various militant networks.
• 1999: A military coup in Pakistan brought Pervez Musharraf to power.
• Pakistan’s support aimed at countering Indian influence in Afghanistan.

2001: 9/11 and Policy Reversal

• September 11 attacks led by Al-Qaeda.
• The United States launched military intervention in Afghanistan.
• Pakistan officially joined the US-led War on Terror.
• Taliban regime collapsed; leaders sought refuge in Pakistan’s border areas.

2001-2014: Dual Policy Era

• Pakistan cooperated with US forces publicly.
• Simultaneously accused by Kabul and Washington of tolerating Taliban sanctuaries in its tribal regions.
• 2007: Formation of Tehrik-i-Taliban Pakistan (TTP), targeting the Pakistani state.
• Blowback began as militant violence intensified inside Pakistan.

2014-2018: Managed Influence and Negotiation Channels

• Pakistan facilitated Taliban participation in talks.
• 2015: Murree peace talks (collapsed after disclosure of Mullah Omar’s death).
• Pakistan sought to retain leverage over Taliban leadership.

2018-2020: Doha Process

• Pakistan supported US-Taliban negotiations.
• 2020: Signing of the Doha Agreement between the US and Taliban.
• Islamabad hoped a Taliban return would produce a friendly Kabul government.

August 2021: Taliban Return to Power

• Taliban captured Kabul after the US withdrawal.
• Pakistan initially welcomed developments.
• Expectations:
  • Reduced Indian influence
  • Cooperative security alignment
  • Control over anti-Pakistan militants

2022-2024: Emerging Frictions

• TTP attacks inside Pakistan surged.
• Kabul refused to decisively act against TTP.
• Border fencing disputes intensified along the Durand Line.
• Taliban asserted autonomy in foreign policy.

October 2025: Major Military Escalation

• Cross-border attacks escalated into significant clashes.
• Air and artillery exchanges occurred.
• Ceasefire mediated by Turkiye and Qatar.

Early 2026: Open Confrontation

• Pakistan conducted air and missile strikes deep inside Afghanistan.
• Taliban retaliated against Pakistani military posts.
• Pakistan’s Defence Minister declared the possibility of “open war.”
• Strategic trust between Islamabad and Kabul effectively collapsed.

Conclusion

The current Pakistan-Afghanistan clashes represent:

• A breakdown of patron-proxy dynamics.
• Strategic blowback from decades of militant instrumentalisation.
• A fragile border is turning into an active military theatre.

The once carefully cultivated Pakistan-Afghanistan (Taliban) relationship now lies fractured under the weight of mistrust, militant spillover, and competing sovereignty claims.

Whether this escalates into sustained conflict or stabilises through renewed mediation will depend on both sides’ willingness to recalibrate strategic expectations and confront the unintended consequences of past policies.
