India-Pakistan Water Dispute: Indus Treaty Abeyance and Diplomatic Leverage

The long-standing Indus Waters Treaty (IWT), a critical water-sharing agreement between India and Pakistan, has become a major flashpoint, with India placing the treaty in 'abeyance' following a deadly terror attack in April 2025 (or May 2025, according to some sources) in Pahalgam, Jammu and Kashmir. India attributes this attack, which killed 24 to 26 civilians, to Pakistan-backed terrorists. India's Permanent Representative to the UN, Ambassador P Harish, articulated India's consistent position at a United Nations Security Council debate on July 23, 2026, stating that cooperation under the 1960 water-sharing agreement cannot continue when 'cross-border terrorism is regularly deployed as an instrument of State policy.' Prime Minister Narendra Modi's statement that 'water and blood cannot flow together' encapsulates India's hardened stance. New Delhi has made it unequivocally clear that the IWT cannot be revived in its current form and that any future water-sharing arrangement will necessitate a revised framework, contingent upon Pakistan verifiably ending its support for cross-border terrorism. India had initiated discussions for a review and modification of the IWT even before the Pahalgam attack, issuing formal notices to Islamabad in January 2023 and August 2024. The Indian government cited demographic shifts, changing climate realities, increased water demand, and Pakistan's continued sponsorship of terrorism as compelling reasons for renegotiating the six-decade-old pact, which it views as 'lopsided' and no longer serving India's interests. Government sources suggest the treaty, in its present form, is effectively finished and a complete overhaul is required. While India is not actively considering a complete withdrawal from the treaty at this stage, it maintains the right as a sovereign state to terminate any treaty demonstrably against its interests, potentially invoking customary international law provisions like Article 60 of the Vienna Convention on the Law of Treaties, which addresses material breach. In response, Pakistan has vehemently condemned India's suspension of the IWT as 'illegal and an act of war.' Pakistani Defence Minister Khawaja Asif issued stark warnings in June 2026, stating that Islamabad would consider military action if India's moves on the Indus river system threaten Pakistan's water security, declaring, 'we will go to war against India' if its national security, which includes water, is threatened. These remarks followed a video clip where India's Jal Shakti Minister C.R. Patil reportedly indicated that the flow of Indus waters to Pakistan could be completely stopped by June 2028. Pakistan has actively sought to internationalize the dispute, raising the issue at various global forums. Pakistan's Permanent Representative, Asim Iftikhar Ahmad, criticised India's decision to place the IWT in abeyance during the UNSC debate. Deputy Prime Minister and Foreign Minister Ishaq Dar raised concerns at the ASEAN Regional Forum and the Indo-Pacific Ministerial Forum Roundtable, portraying India's actions as a challenge to international treaty validity and warning of a potential humanitarian crisis if water supplies are reduced. Pakistan insists that no party can unilaterally suspend the treaty, which has historically survived even wartime hostilities. It has also accused India of deliberately causing flooding in Pakistan, claims that India has dismissed as 'baseless,' attributing the rise in river levels to heavy monsoon rainfall. A notable aspect highlighted by the India Today article is Pakistan's strategic shift in national identity, increasingly embracing the Indus Valley Civilization (Harappa and Mohenjo-daro) as its pre-Islamic heritage. This narrative is reportedly being used to bolster Pakistan's claim as the primary inheritor of the Indus legacy and to strengthen its arguments over the Indus River system waters. Bilawal Bhutto-Zardari, chief of the Pakistan Peoples Party, is cited as linking Pakistan's opposition to India's IWT suspension with this civilizational claim, arguing Pakistan's historic right to the river as its 'defender.' The World Bank, which mediated the original treaty, remains a relevant international body. In 2022, it appointed a neutral expert and a court of arbitration to settle disputes over dams. In June 2025, the court of arbitration ruled that the treaty does not provide for unilateral abeyance and reaffirmed its jurisdiction, a ruling India rejected, calling the court 'illegal.' India maintains that its dealings with Pakistan are bilateral, rejecting third-party mediation and emphasizing that trust can only be rebuilt through Pakistan's verifiable actions against terrorism. India views Pakistan's complaints at international forums as 'desperate attempts to cover up its own failings and divert attention away from its human rights abuses' and 'state-sponsored disinformation.' This escalating dispute underscores the complex interplay of geopolitics, national security, and critical resource management in the India-Pakistan relationship, with significant implications for regional stability.
