The Durand Line, established in 1893 between British India and Afghanistan, continues to attract political and academic debate. While some ethnic centric narratives portray it as an artificial division of the Pashtun people, a closer examination, grounded in international law, regional history, and contemporary realities, presents a more balanced conclusion. The Durand Line is not only a legally valid boundary but also an essential element of regional stability in South Asia.

From the standpoint of international law, the Durand Line stands on firm ground. The principle of uti possidetis juris, widely applied during decolonization, affirms that newly independent states inherit the administrative borders of their predecessors. Pakistan, following its independence in 1947, rightfully inherited this boundary as its western frontier.

Scholars such as S. M. Burke and international legal analysts have consistently argued that this principle is critical in preventing territorial disputes and maintaining global order. Afghanistan’s later political objections do not negate the legal continuity of the border. In practice, the Durand Line has functioned as the de facto and de jure boundary, recognized implicitly in diplomatic engagements and border management over decades.

The international community, including major powers and multilateral institutions, has treated the Durand Line as Pakistan’s legitimate border. This consistent recognition underscores that the issue is not one of legality, but rather of political narrative.

A central argument against the Durand Line is that it divides the Pashtun ethnic group. While it is true that Pashtuns live on both sides of the border, this reality is neither unique nor inherently destabilizing.

Across the Afghan borders, ethnic groups are divided by modern state boundaries. Tajiks live in both Afghanistan and Tajikistan, Uzbeks in Afghanistan and Uzbekistan, and Baluch populations span Pakistan, Iran, and Afghanistan. Yet, these divisions have not resulted in sustained or large-scale political movements demanding border revisions.

Academic works by Barnett Rubin and Thomas Barfield demonstrate that Afghan society itself is highly diverse, with identities shaped as much by local, tribal, and national affiliations as by ethnicity. The assumption that shared ethnicity automatically translates into political unity is not supported by historical evidence.

In Pakistan, Pashtuns have not only integrated into the national framework but have also played a defining role in its development. They are prominently represented in the military, politics, and civil society. This integration challenges the hostile notion that Pashtuns in Pakistan view themselves as separate from the state.

In recent years, movements such as the Pashtun Tahafuz Movement (PTM) have brought renewed attention to issues in Pakistan’s former tribal areas. While some of their concerns regarding governance and development are valid, their framing of these issues often shifts toward an ethnic narrative that risks oversimplification.

By portraying Pashtun grievances as a conflict with the state, such narratives can unintentionally create divisions that do not reflect the broader reality. Pakistan’s Pashtun population is not a marginalized minority seeking separation; rather, it is an integral part of the national fabric.

The selective emphasis on the Durand Line further illustrates this point. If the division of ethnic groups were the primary concern, similar mobilization would be expected along Afghanistan’s other borders. However, such movements are notably absent, suggesting that the focus on the Durand Line is driven more by political considerations than by a consistent principle.

The Durand Line must also be understood within the broader geopolitical environment. Pakistan’s western border has long been affected by instability in Afghanistan, including decades of conflict and the presence of terrorist groups.

Scholars like Ahmed Rashid and Marvin Weinbaum highlight that porous borders and weak governance have created security challenges for both countries. In this context, questioning established borders can exacerbate instability rather than resolve underlying issues.

There is also a strategic dimension to consider. Narratives that emphasize ethnic division can be exploited by external actors seeking to weaken state cohesion. History shows that internal fragmentation often serves the interests of those who benefit from regional instability.

For Pakistan, maintaining a stable and recognized border is essential not only for sovereignty but also for managing security challenges and fostering economic development in border regions.

Pakistan’s approach in recent years has focused on integrating its border regions into the national mainstream. The merger of the former Federally Administered Tribal Areas (FATA) with Khyber Pakhtunkhwa represents a significant step toward political inclusion and economic development.

The Durand Line debate often becomes polarized, framed as a choice between historical justice and modern sovereignty. In reality, these concepts are not mutually exclusive. A stable international system depends on respecting established borders while addressing the needs of communities within them.

The Durand Line is more than a historical boundary; it is a cornerstone of regional stability. While it may not perfectly align with ethnic distributions, it reflects the realities of state formation and international law.
