The Contention Between New Delhi and Islamabad Fuels Border Clashes Between Pakistan and Afghanistan

Introduction

In October 2025, tensions along the porous Pakistan-Afghanistan border escalated into armed clashes, drawing global attention to the deep-rooted geopolitical rivalry between New Delhi and Islamabad. The violence, triggered by alleged Pakistani airstrikes on October 9th, has sparked accusations of territorial breaches, cross-border terrorism, and proxy warfare. This article explores the historical underpinnings of India-Pakistan tensions, the role of militant groups like the Tehrik-e-Taliban Pakistan (TTP), and the implications for regional stability. By analyzing key events, stakeholders, and legal frameworks, we uncover how longstanding animosities continue to destabilize South Asia.

Analysis

Historical Context: The India-Pakistan Rivalry

Relations between India and Pakistan have long been shaped by territorial disputes, particularly over Kashmir. This rivalry has spilled into South Asia through proxy conflicts, with both nations supporting opposing factions in Afghanistan. Since the Soviet-Afghan War (1979-1989), Pakistan backed mujahideen groups to counter Soviet influence, while India strengthened ties with Afghan communists to contain Pakistan’s regional ambitions. Today, this dynamic persists, with Islamabad allegedly sheltering Islamist militants to pressure New Delhi, and New Delhi leveraging Afghanistan to limit Delhi’s strategic depth.

The Role of the Tehrik-e-Taliban Pakistan (TTP)

The TTP, a Sunni Islamist militant group operating since 1997, has intensified attacks on Pakistani security forces, killing over 200 individuals in 2025 alone. Led by Mufti Noor Wali Mehsud since 2018, the TTP operates from bases in Afghanistan’s Kurram and Oruzgan provinces, using yousufzai tribal networks to evade capture. Afghan officials accuse Pakistan of accommodating TTP commanders, despite official denials. India, meanwhile, views the TTP as a tool to weaken Pakistan, exacerbating tensions.

Pakistan’s Airstrikes in Afghanistan: A Legal and Strategic Gamble

On October 9th, Pakistan admitted conducting air strikes near Kabul’s Abdul-Haq Square and in Paktika province, claiming to target TTP camps. These actions followed multiple TTP incursions into Balochistan and Khyber Pakhtunkhwa (KP), including an October 5th attack in Mianwali that killed 23 troops. While Pakistan cites counter-terrorism justifications, Afghan authorities deem the strikes a violation of sovereignty under the 1972 Geneva Accords, which prohibit foreign military operations without consent. The incident has drawn condemnation from the UN and Organization of Islamic Cooperation (OIC), though enforcement mechanisms remain weak.

Regional Dynamics: India’s Involvement and Regional Stability

India has historically supported Afghan governments hostile to Pakistan, funneling aid and military assistance through Kabul. Analysts suggest New Delhi sees Pakistan’s reliance on Afghan resources as an opportunity to amplify political leverage. Conversely, Islamabad perceives Indian support for the Afghan National Army (ANA) and Northern Alliance as a threat to Baloch separatist movements and Kashmiri militant networks. This zero-sum game fuels insecurity, with both sides withdrawing from diplomatic engagement since 2019.

Summary

The Pakistan-Afghanistan border clashes underscore the enduring impact of India-Pakistan rivalry on regional stability. Airstrikes targeting TTP militants have reignited accusations of territorial breaches, while both nations exploit Afghanistan’s fragile security apparatus for proxy warfare. The TTP’s cross-border operations and Afghanistan’s diplomatic neutrality exemplify how historical grievances perpetuate cycles of violence. Addressing these challenges requires multilateral diplomacy, adherence to international law, and coordinated counter-terrorism strategies.

Key Points

Practical Advice for Stakeholders

1. Diplomatic Engagement: Regional leaders must prioritize talks to address grievances, focusing on demilitarization of the India-Pakistan border and TTP disarmament.
2. Strengthen Legal Frameworks: International bodies like the UN should enforce norms against foreign military operations in member states without consent.
3. Community Resilience: Local populations in conflict zones need healthcare, education, and economic opportunities to counter recruitment by militants.
4. Cybersecurity Measures: Governments should enhance digital defenses to counteract propaganda and misinformation spread by extremist groups.

Points of Caution

• Risk of Escalation: A full-scale India-Pakistan confrontation could draw neighboring states like Iran and China into regional conflict.
• Humanitarian Crisis: Civilian casualties from airstrikes and ground operations may overwhelm Afghanistan’s struggling healthcare system.
• Economic Impact: Disruption of trade routes in Balochistan and KP threatens Pakistan’s $1 trillion economy, while Afghanistan’s faltering agriculture sector faces renewed instability.

Comparison: Past and Present Conflicts

Unlike the 1965 Indo-Pak War, which saw direct military engagement, today’s clashes are characterized by covert operations and asymmetric tactics. The 2001 U.S.-led invasion of Afghanistan disrupted Taliban networks but did not resolve underlying issues. Similarly, Pakistan’s 1989 ceasefire with the Taliban (despite ongoing TTP presence) proves peace accords without domestic reforms are unsustainable. The current crisis reflects a shift toward technology-driven warfare, with drones and satellite imagery playing decisive roles in target selection and international condemnation.

Legal Implications

China and Russia, leveraging UN Security Council vetoes, have hindered legal action against Pakistan for violating Afghanistan’s sovereignty. However, the International Court of Justice (ICJ) could theoretically hear a case brought by Afghanistan under the 1989 Vienna Convention on Diplomatic Relations. A ruling against Pakistan might compel Islamabad to cease operations or face economic sanctions, though enforcement remains politically contentious given opposition from Beijing and Iran, both critical Pakistani allies.

Conclusion

The Pakistan-Afghanistan border conflict exemplifies how historical rivalries, unresolved territorial disputes, and militant group sponsorship destabilize entire regions. While Pakistan’s airstrikes and the TTP’s operations are immediate triggers, the root cause lies in New Delhi-Islamabad competition. Sustainable peace demands adherence to international norms, enhanced multilateral mediation, and investments in development over destruction. Without these, the region risks becoming a permanent flashpoint for global security.
