Sir with all due respect to all UN resolution quoters, they mean nothing.
This is an issue between India and Pakistan, and China, insofar as they hold a part of the territory we claim.
We are not going to be able to negotiate or talk to Pakistan on the China held part.
We can only talk and negotiate with them on the Pakistan held part.
Either way, this is going to be resolved by grudgingly accepting what each holds and moving on, or maintaining the status quo and armed conflict.
Wholesale change of territory by force is unthinkable between 3 nuclear combatants sitting cheek by jowl with each other.
What can and probably will continue to happen is territorial attritional conflict like Kargil at one end of the spectrum and small posts and features on the other.
All against the backdrop of sustained covert operations deep into each state with the help of proxies.
My feeling, and this I have articulated more than once in the past, is that Kashmir is no golden sparrow but a red herring.
This fight is left incomplete from 1947, because the Partition was ill conceived and ill executed.
It has been an open wound, and "solving" Kashmir is not going to magically cauterize it.
Cheers, Doc
