(1) That is a mysterious comment. In what way will withdrawing troops from Siachen influence a Kashmiri decision? Are you even aware of the geophysical context? There is not a single voter in the Siachen area.
(2) Even for a Pakistani speaking from the Pakistani point of view, this is a shameless statement. There is unrest in Indian administered Kashmir purely because from the time of Zia, crores of rupees have been pumped into Kashmir, to create a small, hard-core body of agitationists who support Pakistan. They live in a democratic India; in a non-democratic Azad Kashmir, every particle of dissent has been crushed out of existence by a ruthless military regime. Even with the best efforts of this hard-core group, the majority of Kashmiris who talk of azaadi talk of an independent, third-party solution, of independence for Kashmir, an alternative that was removed from the options offered by some schools of thought in the UN by the strenuous efforts of the Pakistani representative.
(3) This is what you say. This is what the moderate section of the Indian political establishment was also willing to concede. You have ensured that the position is lost forever by your own trouble-making efforts. Now that Pakistan has irritated the right-wing, hyper-nationalist sentiment in India over the last 26 years, and now that political power is exercised by that same right-wing, hyper-nationalist sentiment, you may count on this account being re-opened.
(4) Only a cynic determined to preach propaganda would ignore facts and distort history like this.
