When two hijacked planes struck the World Trade Center on September 11, 2001, the consequences rippled far beyond New York. Within weeks, South Asia became one of the most important theatres in the United States’ newly declared Global War on Terror. A region already burdened by partition, unresolved territorial disputes, and freshly tested nuclear weapons suddenly found itself at the centre of global counter-terrorism strategy. Understanding how this happened, and what it meant for stability across the subcontinent, is essential for making sense of contemporary South Asian politics.

Why South Asia became central to the war on terror
The Global War on Terror was launched by the United States in response to the 9/11 attacks, which were planned by al-Qaeda from bases inside Taliban-controlled Afghanistan. Because Afghanistan sits at the heart of South Asia, the entire region was instantly pulled into the campaign. A senior U.S. State Department official told a House panel in 2004 that the September 11 attacks had placed South Asia “on the front lines” of the global war on terror, a region that includes Pakistan, Afghanistan, India, Bangladesh, Nepal, and Sri Lanka.
The reasons were both geographic and strategic. The U.S. needed access, intelligence, and military cooperation to dismantle al-Qaeda and remove the Taliban regime that sheltered it. No country was more critical to this objective than Pakistan, which shares a long and porous border with Afghanistan. What followed was a realignment of alliances that reshaped the politics of the entire subcontinent.
Pakistan as a frontline ally
Almost overnight, Pakistan transformed from a state under international scrutiny for its support of the Taliban into the most important partner of the United States in the region. Under President Pervez Musharraf, Islamabad pledged cooperation, providing logistical support, intelligence sharing, and access to airspace and bases for operations in Afghanistan.
The benefits of cooperation
This realignment brought tangible rewards. Pakistan received substantial economic and military assistance, sanctions imposed after its 1998 nuclear tests were eased, and it regained diplomatic standing in Washington. Scholars note that Pakistan opted to become a close ally of the United States partly because of its long-standing security concerns regarding India and its desire for economic support. For a period, this partnership stabilised Pakistan’s economy and strengthened its position internationally.
The costs Pakistan paid
Cooperation came at a heavy price. By joining the campaign against terrorism, Pakistan invited domestic backlash and a wave of internal violence. Research on the war’s effects argues that becoming a frontline ally brought death, destruction, and serious socio-political consequences, and that counter-terrorism policies ended up importing terrorism into Pakistan itself. Military operations in the tribal regions bordering Afghanistan displaced large populations and fuelled resentment.
There was also a deeper tension in the relationship. As analysts have pointed out, while Washington focused on al-Qaeda and the Taliban, Pakistan’s priorities remained shaped by its rivalry with India and the unresolved status of Kashmir. Many Pakistani Islamists openly condemned the government for cooperating with the United States at all. This divergence of priorities would define the limits of the alliance.
Cross-border terrorism and the India-Pakistan equation
The war on terror did not ease tensions between India and Pakistan. In many ways, it sharpened them. India had long accused Pakistan of supporting militant groups operating across the Line of Control in Kashmir, and the post-9/11 environment gave new urgency to these accusations.
From the Parliament attack to military standoffs
The clearest example came in December 2001, when armed terrorists attacked the Indian Parliament building, killing several people. India blamed Pakistan-backed Kashmiri militants for the assault, which triggered a massive military buildup along the Indo-Pakistani border. This was followed in 2002 by one of the largest military mobilisations in the region’s history, with roughly a million armed personnel deployed along the frontier.
This pattern repeated in later years. Major terrorist attacks attributed to Pakistan-based groups were consistently followed by crises that pushed the two nuclear-armed neighbours toward confrontation. India continued to demand an end to cross-border infiltration, while Pakistan denied direct involvement, creating a cycle of accusation and crisis that proved difficult to break.
A relationship rooted in older disputes
The friction was not new. U.S. intelligence assessments from the late 1980s and early 1990s had already identified Kashmir and “mutual charges of interference” as flashpoints that could ignite crises and confrontations between India and Pakistan. The Global War on Terror layered a new dimension onto these decades-old hostilities, internationalising the question of who was a terrorist and who was a freedom fighter.
The nuclear shadow over the region
What made these tensions so dangerous was the nuclear backdrop. In May 1998, both India and Pakistan conducted nuclear weapons tests, openly declaring themselves nuclear powers. The tests provoked immediate international alarm. The United Nations Security Council expressed grave concern at the negative effect of those tests on peace and stability in South Asia and urged both nations to exercise maximum restraint and avoid cross-border violations.
The nuclearisation of the subcontinent fundamentally changed the stakes of every crisis. Analysts have observed that the 1998 tests transformed the longstanding Kashmir dispute from a regional territorial issue into a potential flashpoint for nuclear war. Every terrorist attack, military mobilisation, and border skirmish now carried the theoretical risk of escalation toward a nuclear exchange.
The world’s most dangerous place
This combination of unresolved disputes, militant infiltration, and nuclear weapons earned the region a grim reputation. The Belfer Center notes that since both countries tested nuclear weapons in 1998, South Asia has been labelled the world’s most likely nuclear flashpoint, with the two states stumbling into serious crisis moments repeatedly. The 1999 Kargil conflict, fought in the high mountains of Kashmir under what observers called the “nuclear shadow,” demonstrated how quickly a limited confrontation could threaten to spiral.
SAARC and the limits of regional cooperation
If terrorism and nuclear rivalry were the problems, regional cooperation was supposed to be part of the solution. The South Asian Association for Regional Cooperation (SAARC), founded in 1985, brought together India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, the Maldives, and later Afghanistan to promote regional welfare and integration.
Counter-terrorism commitments on paper
SAARC was not silent on terrorism. The organisation adopted a Regional Convention on the Suppression of Terrorism, which called for cooperation among member states on extradition and information sharing, and later added an additional protocol on terrorist financing. As the Combating Terrorism Center at West Point observes, the need for greater cooperation figured prominently on the agenda of SAARC summits, but the rhetoric resulted in little concrete action.
Why cooperation stalled
The central obstacle was the India-Pakistan rivalry. Britannica notes that SAARC has been viewed as largely ineffective in fostering regional cooperation, mainly because of political tensions between member states, with India repeatedly accusing Pakistan of supporting terrorist groups responsible for attacks on Indian soil. The 2016 terrorist attack near Uri in Jammu and Kashmir proved decisive. India blamed Pakistan, boycotted the SAARC summit scheduled in Islamabad, and no summit has been held since. A bloc designed to integrate the region became, in effect, a casualty of the very tensions it was meant to resolve.
Radical Islamist groups and ongoing instability
The persistence of radical Islamist organisations across the region remains the most enduring legacy of the war on terror. These groups operate across borders and continue to threaten both individual states and the wider region.
The landscape is varied. Groups such as Lashkar-e-Taiba and the Tehrik-i-Taliban in Pakistan and Jamaat-ul-Mujahideen in Bangladesh are among the violent organisations that have, as one analysis describes, fought to capture or disintegrate the state or impose religious extremism. Afghanistan has been described as a hotbed of militant activity since the formation of the Mujahideen in the 1980s, a movement that eventually produced the Taliban.
The Taliban’s return and its consequences
The Taliban’s recapture of Kabul in 2021 reshaped the regional security calculus once again. The takeover further complicated SAARC’s already fractured dynamics. Pakistan supported Taliban participation in regional forums while other members objected, and as of recent years no SAARC member state has formally recognised the Taliban government. The return of a radical regime in Afghanistan has revived fears about safe havens for militants and the potential for renewed instability spilling across borders, underscoring how the issues raised by the war on terror remain unresolved more than two decades later.
The lasting legacy
The Global War on Terror left a deep and lasting mark on South Asia. It elevated Pakistan to the status of a frontline ally while simultaneously exposing it to internal violence and political strain. It intensified the rivalry between two nuclear-armed neighbours, kept Kashmir at the centre of regional conflict, and repeatedly tested the fragile mechanisms of cooperation that bodies like SAARC were meant to provide. The campaign that began as a response to a single day in 2001 ended up entangling the political futures of nearly two billion people. For a region defined by both immense potential and persistent insecurity, the war on terror remains a defining chapter in the story of why lasting stability has proven so elusive.
What do you think? How can South Asian countries balance legitimate national security concerns against the urgent need for regional cooperation? And should the responsibility for addressing the root causes of terrorism in the region rest primarily with individual states, or with the international community?
