This may not go well with the PDF members here, and Iam sorry to say that. But India will happily sacrifice few thousand soldiers and kill few hundred thousand kashmiris every year rather than compromise on its sovereignty. If that is the cost, so be it...
US left Afghanistan without losing a single battle, because it values its soldiers way too much, and tried fighting a war with too much sophistication, hence jacking up the cost.. why do you think Asad is winning in Syria? Because it demonstrated ability to kill and take punishment at the same time.
Don't underestimate India's ability to become brutal. It has demonstrated many times Punjab and Kashmir. Even these incidents will be responded in equal brutality impacting families and sympathizers.. that is the true side of the conflict
