The relationship between India and Pakistan has become a bouncing ball which has been bouncing since 1947 without reaching at its desired acceptable position.  This ball has been bouncing from one hand to another like a hot potato no one party wants to hold for a long time.  Whenever there seems to be a little ray of hope to ameliorate relationship, something negative occurs whether in the shape of an unacceptable anti-India remarks by one of the government or military official of Pakistani establishment or some type of ceasefire violation at the LOC.  Recent verbal agreement at Ufa, Russia between Prime Ministers Sharif and Modi is a live example.  Mr. Modi accepted Mr. Sharif's invitation to visit Pakistan next year and then today Mr. Sharif's National Security Advisor, Mr. Aziz, released a statement that there will be no negotiation with India unless a core issue of J & K is incorporated in the agenda to be discussed.  This writer is very confused and trying to find out who is the boss in Pakistan.  Is it the Prime Minister of Pakistan or his National Security Advisor or the nexus of Military/ISI?  Since the number of issues involved and the ideology  and determination of resolving these issues require open mind, this writer is very pessimistic to see it happening ever at least not in the near future.  India' plea is that J & K is part and parcel of India whereas Pakistani authorities including the military establishment always claim that there will be no negotiation unless J & K issue which in their mind is the core issue becomes part of the negotiation.  Under this scenario, how can one expect to achieve what each party wants to achieve when their opinion on this issue is diametrically opposed to each other?  Am I missing something?  However, my opinion is that negotiating with Pakistan is a waste of time, energy and resources which India can rightfully divert to some other useful direction to extract more mileage than waiting for Pakistan to change its attitude.  INDIA JUST NEEDS TO SHUT ITS DOORS ON THIS TOPIC.
