Water War
A hydro race is underway in South Asia, with a looming threat of a full-scale war between Pakistan and India.

The Pahalgam terrorist attack exposed serious deficiencies in India’s national security apparatus; militarily, it overplayed its hand into a dead end of embarrassment. While suspending the Indus Waters Treaty (IWT) was an absurd move in foreign policy, it was not surprising from the Narendra Modi government. It may be recalled that in 2016, post-Uri terrorist attack, Modi had politicized the IWT, famously chanting “blood and water cannot flow together” in the days leading up to the BJP Congress by-elections. But the world is not buying it. The Permanent Court of Arbitration, in its “Supplemental Award of Competence,” and the President of the World Bank (third-party guarantor in the IWT) have unequivocally established that the treaty lives and breathes as per its own legal bindings; no provision within the IWT allows India’s unilateral suspension or abeyance.
Even under international treaty or customary law, Articles 60–62 of the Vienna Convention on the Law of Treaties (VCLT) provide narrow and strict grounds for unilateral termination or suspension: a material breach by the other party, a fundamental change in circumstances, or the impossibility of performance of a treaty—none of which are applicable under the current circumstances.
It is part of the public record that India had been pushing for modification of the IWT through multiple formal notices, which Pakistan refused to entertain, content with the treaty in its current form. Pursuant to Article XII(3) of the IWT, any modification must involve consensus between the two governments.
However, India’s strategic intentions gradually surfaced after the Pahalgam incident. Amit Shah declared the suspension permanent in brazen disregard for international law and vowed to divert Pakistan’s share of water under the IWT. In response, Pakistan’s National Security Committee has cautioned that any attempt by India to divert Pakistan’s water will be considered an “act of war.” Most recently, Ishaq Dar, on the sidelines of the ASEAN Foreign Ministers’ Meeting in Kuala Lumpur, termed India’s suspension of the IWT “a strange thing,” stressing that Pakistan’s responses have been defensive, proportionate, and “tit for tat” in nature. He further reiterated the National Security Committee’s “act of war” stance.
Modi’s government reportedly pushes for the speedy construction of four hydro projects with a combined capacity of 3,014 megawatts. These are: Pakal Dul (1,000 MW), Kiru (624 MW), Kwar (540 MW), and Ratle (850 MW). All of them are on the Chenab River, designated for use by Pakistan under the IWT. Not so surprisingly, a feasibility study is also underway for a 113-km canal diverting surplus flows from Jammu & Kashmir to Punjab, Haryana, and Rajasthan. This canal would link the Chenab River with the Ravi-Beas-Sutlej system. Meanwhile, in Pakistan, China has assured us it will speed up the construction of the Muhammadan Dam, and the Diamer Basha Dam has become the top priority on the government’s agenda. It turns out a hydro race is already underway in South Asia, with a looming threat of war.
Nevertheless, the reality is that the IWT continues to be in force; thus, non-adherence to treaty provisions constitutes a material breach under international law. Therefore, Pakistan ought to monitor Indian activities on its three designated river systems with the assistance of advanced satellite technology and maintain a record of notable breaches of treaty provisions. India’s unilateral suspension constitutes a breach concerning data sharing, transparency of planned projects, and Permanent Indus Commission-related obligations under Articles VI–VIII of the IWT. The World Bank may be informed of all ongoing breaches by India and plans via the office of Pakistan’s Commissioner to the Permanent Indus Commission.
In light of any new evidence gathered regarding India’s planned projects or ongoing activities, Pakistan’s legal team may attempt to amend the claim before the Permanent Court of Arbitration (PCA) according to Article 22 of the PCA Rules 2012, to demonstrate anticipatory breach given India’s pattern of bad-faith practices surrounding the IWT.
Separately, Pakistan may also seek interim relief under Article 3 of the PCA Optional Protocol on Emergency Interim Measures 2024 against India’s future planned projects and ongoing IWT violations. This may result in a ruling of injunctive relief against India’s plans.
In parallel, in the proceedings before the Neutral Expert, Pakistan’s counter-memorial is due on 7th August 2025, per the latest work program. Pakistan may highlight India’s future plans and ongoing violations of technical treaty provisions. At the very least, Pakistan may gain reaffirmation from the Neutral Expert that the treaty remains in force despite India’s unilateral suspension. It is important that India’s actions and plans form a part of the record at both the PCA and before the Neutral Expert.
In addressing IWT-related breaches and escalating disputes, Pakistan may also rely on customary international law to highlight India’s violations through diplomatic outreach. The 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses (UNWC), although not ratified by India but widely accepted as customary law, requires states not to cause significant harm to co-riparian states (Article 7), to ensure equitable and reasonable utilization (Articles 5 & 6), to share regular data (Article 9), and to notify, consult, and negotiate planned measures (Part III).
Furthermore, Pakistan may highlight India’s planned canal diversion and other technical breaches in dam construction as violations of the right to water and life, protected under UNGA Resolution 64/292. The move threatens downstream communities in Punjab and Sindh and may also be raised before the UN Human Rights Council through the Special Rapporteur on the human rights to safe drinking water and sanitation.
India’s plans are also likely to exacerbate Pakistan’s climate vulnerabilities, affecting critical flows, resulting in transboundary environmental harm and climate injustice. This angle may be taken up at COP and UNFCCC side events.
If India wishes to re-engage on water issues, it is likely to insist upon modification of the IWT. If Pakistan agrees to negotiations, these must be mediated by the World Bank or a neutral third party and should strictly adhere to international treaty law and customary principles.
Furthermore, any lasting settlement to transboundary water-sharing issues in the Himalayas would require China at the table. After all, it is the uppermost riparian state of the Indus River System. Perhaps a more proactive role by China could even end this hydro race in South Asia.
Water is too critical a resource and should not fall victim to political maneuvering or become part and parcel of either party’s lawfare arsenal. Pakistan’s stance is grounded in international law, and any successful outcome is incumbent upon staying the course of the rules-based international order.![]()

Excellent write up. Very well researched and incisive. Good choice of words with very flowing natural expression. Very well done!
The Pahalgam terrorist attack, connected to broader security and diplomatic issues, has provided India with a pretext to suspend the Indus Waters Treaty (IWT). This situation offers a valuable opportunity to delve into the complex regional dynamics and related legal and political challenges.
Incorporating official reactions from Pakistani officials and the geopolitical context—particularly hydro projects, water diversion, and dam constructions—aligns with open sources and current developments. It is crucial for authorities to treat this issue with urgency, considering these insights as a basis for early resolution.
The article presents a nuanced understanding of the legal and diplomatic landscape, linking recent military and diplomatic posturing with the IWT dispute. Specific project details and figures lend credibility, while phrases like “brazen disregard” and “hydro race already underway” reflect a strong tone that could be scrutinized for bias. Nonetheless, maintaining objectivity is challenging in such politically charged discussions.
Advocating a multipronged approach, the article calls for legal action, diplomatic engagement, environmental advocacy, and regional cooperation—particularly involving China. Emphasizing adherence to international law and rules-based order aligns with Pakistan’s strategic legal stance.
