India is not going to stop the water. We don’t have the capacity to, nor should we attempt to. But the thing is, we have always had issues with the treaty, that didn’t allow us to fully exploit our rights over what was allocated to us in the treaty. Eg Kishanganga project which Pak blocked till arbitration ruled in our favour.
Further, we have additional needs given today’s realities - demographics, drinking water, irrigation and other needs. Imagine Kashmir is facing water crisis - with all those rivers flowing there.
So suspending the treaty allows us to figure out how much more water we need from the Western rivers and undertake projects thereof. It won’t happen overnight.
The point is to not stop waters, but use more of it for our needs. Pakistan was unwilling to renegotiate. Now we have found a good reason to do it without talks.
If Pakistan is troubled by it, then it has to talk to us, because we have not walked away from it, but suspended it. We will talk only if they stop terror - which they won’t.
Suspension and not abrogation puts us in a heads I win, tails you lose advantage.
