The only way Kashmir can solved is when Pakistani military boots are on the ground in Srinagar. Even at that point, it would be our responsibility to conduct a plebiscite.
In other words, the Kashmir issue can never be resolved ? I am really surprised that you are so concerned about Kashmir which is Indian territory when you are unable to control the territory which is still yours.
Remember - "a bird in hand is worth two in the bush".
Rather than salivate about Kashmir, think about consolidating and improving what you have.
