Showing the world that India is violating its international commitments is a good place to start.
But then won't that be hypocritical, when Pakistan tried to unilaterally change the LOC, in Kargil. And as most Pakistanis like to boast here, how Pakistan still hold, some Indian peaks. (thereby altering the situation in Kashmir).
I am sure, if Pakistan goes ahead, with this line of argument. India would give the Kargil argument.
Besides just last year GB was declared the defacto province 5th province of Pakistan. India protested this even back then.
