On June 30, I had the honour of speaking at the Institute of Regional Studies seminar on the Indus Waters Treaty, held at the Jinnah Convention Centre in Islamabad. The Indus Waters Treaty reflects that lesson. India’s declaration in April 2025 that it was placing the Treaty in abeyance, following the Pahalgam terror attack, has no basis in international water law. The Permanent Indus Commission must be allowed to meet. The Indus Waters Treaty must not be allowed to fail.
