India resorted to using water as a weapon of war against Pakistan in the very first few months after our independence. Choking Pakistani water was one of the first weapons used by India against a weak, newly-born Pakistani state. It is part of a long list of 'firsts' that India introduced into its relationship with Pakistan. Some of these 'firsts' include the use of non-state actors [started in 1950 by India through lawless Afghan regions to stoke separatism in western Pakistani provinces] and nuclear weapons [1974 nuclear detonations]. In another first, India launched an unprovoked invasion across international borders in 1965 & 71 to seize territory. It was later followed by the occupation of Siachen during 1984. These days, India is busy introducing nuclear submarines and aircraft carriers in Pakistani seas.
In short India has left no stone unturned to transform a simple international dispute with a neighbour over Kashmir into a multifaceted conflict and a running blood feud.
But far from a policy of fair use, India is dotting the Kashmiri landscape with large and small dams that exceed its need and requirement. This massive dam buildup ignores the fact that it is happening on a disputed territory that remains on the UN Security Council agenda awaiting resolution. The Indian dam buildup is like creating a large valve that can be turned off any time to punish Pakistan, or to thirst it to death or surrender.
