Two Pillars, Two Demolitions: How India and Pakistan Are Taking Down the Indus Treaty From Opposite Ends

The Indus Waters Treaty survived three wars, multiple border crises, and decades of hostility because it rested on two design choices that were unusual for an agreement between adversaries. It was apolitical: water flows would be governed by technical allocation rules, insulated from whatever else was happening between the two countries. And it was bilateral: disputes would be resolved between New Delhi and Islamabad, with the World Bank as guarantor but no third-party adjudicator with enforcement power. Those two pillars are now being taken down simultaneously, one from each side, by the parties who built them. India is destroying the apolitical pillar. After the Pahalgam attack in April 2025, Modi declared that

blood and water cannot flow together — Narendra Modi

— coupling the treaty's operation to the security relationship, the precise linkage its 1960 design excluded. India's MEA then formalized the suspension, stating it was "no longer bound to perform any of its obligations under the Treaty" and that restoration required Pakistan to "irrevocably end[] its support for cross-border terrorism" ^[1]. A year later, at the treaty's anniversary, Modi sharpened the demand further, calling the IWT itself "unacceptable to us in the interest of our farmers, and in the interest of the nation" ^[2]. India's UNHRC representative put the case in explicitly architectural terms, arguing that the treaty "cannot be treated as a perpetual entitlement which is insulated from accountability, detached from present day realities" ^[3]. That is not a complaint about implementation. It is an argument that the insulation itself is illegitimate — targeting the design feature, not the terms. India's Water Minister gave the logic a physical endpoint: the flow to Pakistan "could be completely stopped by June 2028," with "not a single drop of India's share of Indus waters" leaving the country ^[4]. The apolitical pillar, in other words, has a demolition date. Pakistan is destroying the bilateral pillar. Deputy PM Ishaq Dar wrote to the UNSC in June 2026 urging international intervention, framing India's actions as "deliberate acts of hydro-hegemony" and arguing the dispute is "not just bilateral" ^[5]. Pakistan's representatives at the Security Council folded the water issue into a broader multilateral indictment of India's conduct, describing a state that "weaponises water" alongside "occupation, aggression, repression and disregard for international law" ^[6]. Pakistan has also invoked the Vienna Convention on the Law of Treaties, the 1977 UN Watercourses Convention, and the self-defense framework of UN Charter Article 51 — building a legal case that runs through every multilateral instrument available while bypassing the treaty's own bilateral dispute mechanisms ^[7][8]. Pakistan even enlisted China to jointly raise the IWT and Kashmir at the UNSC, bringing a third party into a framework designed for two ^[9]. The contradiction is not just that each side attacks a different pillar. It is that each side is the self-appointed guardian of the pillar the other is tearing down, and quotes the principle the other is violating as proof of its own righteousness.

the pillar each party attacks and the one each defends

India: attacks apolitical, defends bilateral: India makes treaty restoration contingent on Pakistan ending "sponsorship of cross-border terrorism" ^[1] while insisting at the UN that "no other country has the locus standi to comment" on the dispute — defending the bilateral exclusivity Pakistan is eroding ^[9]. India invokes the Vienna Convention's "fundamental change of circumstances" doctrine to justify unilateral suspension, using international law to authorize bilateral action, not invite third-party adjudication ^[10].

Pakistan: attacks bilateral, defends apolitical: Pakistan appeals to the UNSC and multiple international legal frameworks to internationalize what the treaty kept bilateral ^[5] while insisting that "water cannot be treated as a political tool or instrument of coercion" — defending the apolitical insulation India is destroying ^[8]. Pakistan frames any disruption of water flows as potentially "an act of war under Article 51 of the UN Charter," invoking the UN's security architecture rather than the treaty's technical dispute mechanisms ^[8].

The same paradox plays out in how each party uses the multilateral stage. Both India and Pakistan show up at the UN to argue about the treaty, but for diametrically opposite structural purposes. India uses the forum to assert bilateral exclusivity — the dispute is ours, no one else has standing. Pakistan uses the same forum to invite third-party intervention — the dispute is everyone's problem. They are in the same room, speaking past each other on the same architecture ^[9]. The treaty's own dispute resolution machinery is now contested by both sides, which compounds the damage. The Permanent Court of Arbitration ruled in June 2025 that the IWT "remains in force and cannot be unilaterally suspended" — a ruling in Pakistan's favor ^[5]. India rejected the court's jurisdiction as "illegally constituted," calling the arbitration proceedings "a charade and fabricated mechanism initiated by Pakistan to evade accountability for terrorism," and redirected to a World Bank Neutral Expert instead ^[1]. India is forum-shopping within the treaty's architecture, accepting the forum that serves its leverage and rejecting the one that doesn't. Pakistan, having won in court and gained nothing because India walked away from the table, escalated to the UNSC. The sequencing matters: Pakistan's internationalization is not a first resort. It is a second-order response to the bilateral and legal mechanisms no longer functioning because India rejected the forum that ruled against it. That leaves the treaty's survival mechanism broken from both ends. The technical dispute resolution that kept water out of politics is now itself a contested political object — India treats it as an instrument to be accepted or rejected based on leverage, Pakistan exits it for the Security Council. The apolitical pillar has a hydraulic deadline of June 2028. The bilateral pillar has no deadline but no obvious path back either, because the party that internationalized the dispute did so after the bilateral mechanism was already dead.

The treaty survived 66 years not because India and Pakistan trusted each other, but because they agreed that water should be governed by rules rather than politics and by two parties rather than a committee. Each side is now demolishing one of those agreements while invoking the other as a principle worth defending — a contradiction so precise it reads as design, though the evidence shows two separate strategies converging on the same collapse point. ^[1][5][3][8]

Pakistan's position has one more vulnerability its UNSC strategy does not fix. The country faces a domestic water crisis — deficits in North West, Rice, and Dadu canals affecting roughly a third of the population — that some experts attribute to domestic mismanagement rather than Indian action ^[4]. The treaty's bilateral technical mechanisms were designed for exactly this kind of problem: allocation disputes resolved through measurement and negotiation. Pakistan's response has been to internationalize rather than seek bilateral technical cooperation, which is the one mechanism the treaty actually provided. And Pakistan's Defence Minister has separately threatened military action if India "starts building structures" quickly ^[4] — a bilateral militarized track running alongside the multilateral legal one. Pakistan is operating on both tracks, but the bilateral track it still uses for threats is the same track it has abandoned for solutions. India offered treaty modification negotiations in 2023 and 2024, which Pakistan refused ^[10]. That context matters: India's politicization came after bilateral modification failed, not out of nowhere. But the choice India made — to convert a failed negotiation into a conditional suspension linked to terrorism — still converts the treaty from a technical agreement into a political instrument. The fact that there were alternatives does not change what the suspension does to the architecture. The result is a treaty whose two load-bearing principles are each under attack by the party that benefits from the other one. India wants bilateral control without apolitical insulation. Pakistan wants apolitical protection without bilateral exclusivity. What neither party wants is what the treaty actually was: both at once. The Indus Waters Treaty was never a peace agreement. It was a system for keeping water separate from everything else, handled by the two people who share the river. That system is being taken apart by the same two people, each holding the piece the other is trying to pull down.
