I agree with you on this. This is a good opportunity for India to help and even the US has offered to assist in whatever way they can. Honestly we would be happy if our forces could lend a helping hand and launch a rescue operation. There is no harm in trying even if there is less hope. If somehow the miracle happens and Indian soldiers are deployed for rescuing your soldiers, then it would be a great step towards the closing of the gap/bridge between our two countries. We dont know the fate of these trapped soldiers but trying to rescue them could help prevent another war that could cost much more and develop a friendship that we have missed since independence.
However the process will start either with the Pakistani side asking for help or the Indian side offering it, neither of which has happened yet. The Pakistani media is already killing the morale of the rescue as time withers away. The key in such situations is not to give up because that's all we can do.
