I don't see why we're even discussing this. Who won or who lost is immaterial now. Here are a few practical ideas for my pakistani friends (and indians too) to consider.
1.In the modern world borders matter little, if Pakistanis really want kashmiris to be happy they shouldn't be bothered what country owns that land. They should instead want kashmiris to enjoy a better life, whether with India, Pakistan, China or on their own. Granted there are human rights problems in IoK but they are simply because the Army does not know whom to suspect and thus many innocents do get killed.If Pakistan stops promising liberation to them, they'd get back to work and livelihood and prosper in the booming Indian economic landscape.
2.Kashmir is an emotional issue for Pakistanis simply because they associate religion with it. The logic - Pakistan is a Muslim state-->Most Kashmiris are Muslims--->Therefore Kashmir should belong to Pakistan -This logic simply does not apply because India is a secular country. Although there have been tensions between Hindus and Muslims, they are nowhere near the scale which the creators of Pakistan had predicted. So why can't Kashmiris stay in India.
3.Past issues like UN resolutions are old nonsense that all parties should stop harping on if they want peace. For every argument that the Pakistani side has about resolutions and stuff, Indian side has a counter-argument. As far as reality and practicality is concerned these old resolutions and treaties hold little relevance now.
4.The only viable option is 'to maintain status quo and turn the LoC into international border'. Indians are much more willing to accept this than the Pakistanis i have met. And this may I add, is not because India holds more kashmiri territory than pakistan - Indians are in general willing to pay such costs for peace, for example India does not press the issue of territory with China after they annexed some of it from India. India is happy, India is growing, prosperity is increasing even if slowly and Indians are satisfied.
5.Unless Pakistan and its citizens detach two things - Emotion and Religion from the Kashmir issue and insist on taking Kashmir by force or forcing a plebiscite or fostering an insurgency, No solution is possible. Simply because Pakistan will keep showing Kashmiri muslims hope that there will be 'liberation' or 'plebiscite' one day, and they will never feel like Indians. If they do not feel like Indians, some of them will support the insurgency. If they support the insurgency, the Indians will not feel sympathetic towards their human rights issues. Till Indians do not feel sympathetic towards kashmiri human rights, The Army will feel guarded towards kashmiris and maintain mistrust. Till this mistrust exists, there will be human rights issues.
6.You see tagging an emotion to a peice of land on the basis of religion is to no one's advantage. Neither the Kashmiris (whom pakistan claims to be acting in interest of), Nor Indians, Nor Indian army, Nor Indians gain anything from it. No child is born with a religion, his parents give him one. Many people forget this when they discuss Kashmir.
Goodbye, this will be my last post here. It is not about the 65 war, or the 71 or the 47 war either. It has always been about religion, emotion, impracticality, and stupidity.
