You can there is no rule that prevents it. You can claim all lands in India as much as you can, but in reality however
Acha so now rules matter?
By the way, there very much IS a "rule" that prevents India from unilaterally suspending or "placing in abeyance" or withdrawing from the IWT.
Basics of contractual law for self-styled hydrology experts here:
"The PCA observed that Article XII of the IWT states unambiguously that the Treaty shall remain in
force until terminated by mutual agreement. No clause permits unilateral suspension. Invoking
established precedent, the Court held that once proceedings are validly seized, no party may
withdraw jurisdiction through subsequent acts. Allowing one side to press pause on arbitration
would, the supplemental award reasoned, vitiate the Treaty’s compulsory third-party settlement
machinery. The PCA,therefore, declared a continuing responsibility to advance these proceedings in
a timely, efficient and fair manner.
India had argued that ‘fundamental change’ of circumstances and a ‘material breach’ justified
putting the Treaty in ‘abeyance.’ The PCA rejected that stance. The ruling clarified that its logic also
binds the Neutral Expert proceedings that India initiated in parallel. This closes a loophole by which
either party might engage in forum-shopping to delay final adjudication of dam-design disputes."
The people of the Netherlands must have known you lot very well in some previous historical incarnation somewhere.
