Despite the rising tension over Kashmir, India has neither the impetus nor the ability to abolish the Indus Waters Treaty overnight. To officially abrogate the agreement, as some commentators have suggested might happen, would require a second ratified treaty according to the 1969 Vienna Convention on the Laws of Treaties. Beyond the legal hassle, India does not need to overturn or even formally violate the treaty to turn its shared water supply into a negotiating tool in the dispute over Kashmir. Under the treaty, India is allowed the use of 20 percent of the basin's western rivers (the Indus, Chenab and Jhelum) for agricultural and nonagricultural purposes, including navigation and hydropower projects. As it stands, however, India uses only a fraction of its allotment and could leverage plans to expand its activities on the Indus River Basin without breaking its agreement with Pakistan.
