I never implied that India should agree on anything unilaterally. However India and Indians need to realize that Kashmir isnt being carved out from India as a religious state but this is a problem arising from partition, a dispute left unsettled. If you read history, partition was done on religious grounds with muslim majority areas transferred to Pakistan while hindu majority areas transferred to India. So this argument that we cannot let another state be created on religion does not exist when this dates back to the original partition.
Plus even if we are sending terrorists as per India, the Pakistani flags hosted in Kashmir are not done by those terrorists, they are done by the local population unless you consider them all to be Pakistani terrorists. The vicious cycle only continues when India does not want to address the root cause of the problem and is suppressing any voice by brute force. How would Pakistani so called terrorists find support if Kashmiries back India? Do you think Pakistani based terrorists get the same support in lets say Delhi or Mumbai or Kerala?
This is easy for India to just say hey Pakistan is fueling terrorism otherwise Kashmir wants to stay with India and everything is rosy because this is further from the truth and deep down every Indian knows.
Besides If India is so sure than why not hold a plebiscite and let this debate settle once and for all. If Kashmiries vote for India, Pakistan will lose its part of Kashmir as well.
