The Indus Waters Treaty: Vajpayee’s Criticism, Congress Opposition, and Its Enduring Controversy

When the Indus Waters Treaty (IWT) was signed in Karachi on 19 September 1960, it was hailed internationally as a rare example of cooperation between two hostile neighbors—India and Pakistan. Brokered by the World Bank, the agreement sought to end years of wrangling over river rights following Partition. Prime Minister Jawaharlal Nehru and Pakistan’s President Ayub Khan put their signatures on a document that divided the mighty Indus river system between the two countries.

Under its terms, the eastern rivers—Ravi, Beas, and Sutlej—were allocated to India, while the western rivers—Indus, Jhelum, and Chenab—were reserved for Pakistan. India retained only limited rights over the western basin, restricted to non-consumptive uses such as hydropower generation, navigation, and irrigation on a modest scale. Effectively, India received only about 20% of the Indus system’s waters, while Pakistan obtained nearly 80%.

Although celebrated abroad as a triumph of diplomacy, at home the Treaty sparked sharp criticism. Many MPs—across parties—voiced concern that India had made disproportionate concessions to Pakistan. Among the most forceful critics was a young parliamentarian, Atal Bihari Vajpayee, who would decades later become India’s Prime Minister.

Vajpayee’s Intervention in Parliament

In the Lok Sabha debate on 30 November 1960, Vajpayee accused the Nehru government of having signed away India’s strategic water rights without adequate deliberation. He stressed that while the government might possess the legal authority to negotiate international treaties, the sheer magnitude of the Indus settlement demanded full parliamentary scrutiny.

Vajpayee’s core arguments were threefold:

  1. Democratic Deficit – He lamented that Parliament had not been consulted before the agreement was finalized. For a democratic republic, he argued, bypassing elected representatives on such a matter was deeply troubling.
  2. Strategic Risk – Vajpayee drew attention to Ayub Khan’s remarks suggesting that “joint inspection” of upper riparian projects implied joint control of Indian rivers. He warned that this interpretation could undermine India’s sovereignty in Jammu and Kashmir.
  3. Unequal Bargain – By allowing Pakistan a lion’s share of the waters, Vajpayee argued, India had sacrificed long-term interests for short-term appeasement. He feared that the agreement would embolden Pakistan rather than moderate its hostility.

Vajpayee concluded by calling the Treaty a “sell-out” of India’s rights, predicting that it would haunt future generations. His warning would echo across decades, resurfacing whenever Indo-Pak relations deteriorated.

Congress MPs Also Expressed Dissent

What is often forgotten in popular retellings is that Vajpayee was not alone in his disapproval. Even within the ruling Congress Party, several MPs expressed misgivings. Some questioned the fairness of allocating only a fraction of the Indus waters to India, especially when the country was still battling drought and food insecurity.

Others criticized the government for treating Parliament as a mere formality. They argued that an agreement with such profound implications for agriculture, energy security, and territorial sovereignty should not have been concluded without debate, detailed study, and ratification by the legislature.

Thus, opposition to the Treaty was not confined to the Jan Sangh or opposition benches—it cut across party lines. Nehru, however, pushed forward, emphasizing the need for peace with Pakistan and the importance of international goodwill. For him, the IWT represented a bold step toward reconciliation in South Asia.

The Treaty’s Resilience Through Conflict

Despite the initial resistance, the Treaty survived. Even after the wars of 1965 and 1971, the Kargil conflict of 1999, and recurring diplomatic crises, neither country abrogated it. The Permanent Indus Commission (PIC), a bilateral body set up to resolve technical issues, continued to meet even during wartime.

The durability of the IWT is often cited as proof of its success. International observers praised it as a “bright spot” in otherwise hostile Indo-Pak relations. For decades, it stood as an example of conflict-management rather than conflict-resolution.

Yet critics inside India repeatedly pointed out that this endurance came at a cost. By restricting itself largely to the eastern rivers, India limited its agricultural and hydropower potential in Jammu and Kashmir. Meanwhile, Pakistan depended heavily on the Indus system to sustain its agrarian economy, making it more intransigent in political negotiations.

Contemporary Reappraisal: Modi and Jaishankar’s Criticism

Fast forward to the 2020s, the debate resurfaced with renewed intensity. Prime Minister Narendra Modi famously declared that “blood and water cannot flow together” after a series of terrorist attacks linked to Pakistan. His government began exploring ways to maximize India’s legal rights over the eastern rivers and accelerate hydropower projects on the western basin.

By 2025, following the Pahalgam terror attack, India went a step further by announcing the suspension of the Treaty, arguing that Pakistan could not simultaneously export terror and benefit from India’s waters. External Affairs Minister S. Jaishankar openly called the IWT a “historic blunder”, stating that it symbolized a mindset of appeasement rather than peace.

The Modi government’s stance bore striking resemblance to Vajpayee’s warnings in 1960. Both leaders emphasized sovereignty, fairness, and national security, contrasting them with what they perceived as Nehru’s misplaced idealism.

Was Nehru’s Gamble Worth It?

To be fair, Nehru’s intentions were not entirely misplaced. He saw the Treaty as a way to avoid perpetual water conflict, strengthen India’s global image, and secure World Bank funding for large dam projects like Bhakra Nangal. For a newly independent nation, international credibility was a valuable asset.

But in retrospect, critics argue that the price was too high. By conceding the bulk of the waters to Pakistan, India constrained its own long-term development in Jammu and Kashmir. Worse, Pakistan did not moderate its hostility despite this concession—it continued to wage wars, sponsor militancy, and stall Indian projects through international arbitration.

Even Congress leaders in later years admitted that Nehru may have miscalculated. Some called it a “historic blunder,” echoing Vajpayee’s phrase. The dissent from Congress MPs at the time now appears prescient, as does Vajpayee’s sharp critique.

Lessons for the Future

The Indus Waters Treaty offers several enduring lessons:

  1. Democratic Oversight Matters – Major international agreements must involve parliamentary debate and scrutiny. Sidestepping elected representatives undermines transparency and accountability.
  2. Strategic Prudence Over Idealism – While peace is a noble goal, it must not come at the cost of permanent structural disadvantages. Concessions should be measured, reciprocal, and enforceable.
  3. Agreements Must Be Flexible – A treaty signed in 1960 may not suit the realities of 2025, especially under climate change, population growth, and technological advances. Revisiting and updating such frameworks is essential.
  4. Cross-Party Consensus – Water security is too critical to be left to partisan politics. The fact that both Vajpayee and Congress MPs opposed the IWT underscores the need for a national approach on strategic resources.

Conclusion

The story of the Indus Waters Treaty is not merely about rivers—it is about sovereignty, foresight, and the balance between peace and pragmatism. Vajpayee’s fierce intervention in 1960, supported in part by dissenting Congress voices, reminds us that democratic scrutiny should never be sacrificed in the name of expediency.

More than six decades later, India’s reassessment of the Treaty validates many of those early concerns. What Nehru saw as a bold gamble for peace, others recognized as a dangerous concession. History now judges the Treaty less as a diplomatic triumph and more as a contested legacy—one that continues to shape Indo-Pak relations and India’s internal debate on water security.
