I think at this point everything is theatrics. Indians would know details of Jadhav and would not need to talk to him to find out. Being a "guest" this long, Jadhav would not have much left to disclose to Pakistanis. Now this thing can be closed only in few ways. 1. Release his as a swap for another prisoner. 2. Release him unilaterally. 3 Kill him "accidentally". 4. Execute him as per judgement.
None of which are very good options for Pakistan Government. Can't do 1 & 2. If they do 3. it will not look good internationally. For 4 they need World to be satisfied that due process was used. That is why all this noise about consular access, I think.
[For folks who will ask why 3 & 4 are not good options. India is claiming that he was kidnapped from third country. Global community will not be amenable to supporting that for obvious reasons. Emotions aside look up International Court Verdict.
Unfortunately onus is on Pakistan to prove that he is Guilty (without his confession). Unfortunately they have not done a good job in that. It may be to keep their intelligence assets protected. But it does present a pickle for them.]
Edited : fixed grammar...
I will say my part simply so that much of ambiguity will be gone.
Every power corridor, the players in spy games & all those big players already know & being shared with enough evidence about KY. Not a single player, I mean even the most & closest or reliable partner of India interfered or will try to pressurize Pakistan by any means or even tried to trick Rawalpindi in favour of India at all. You know why? they all knew it and even India knew it. Then comes all the hogwash attempt of India through Media frenzy to twist the facts and utilize the last resort so that could get anything out of situation to prove themselves innocent. Indian Establishment through media played all the tricks to manipulate and even reported the wrong contexts. ICJ did not overturn or overruled the judgment by Pakistan Military Court instead, it is said that to provide fair proceedings and counselor access. The case in ICJ per Indian pleading, is lost as there comes nothing to say that Kalbhushan is Patel let alone the businessman.
Now comes the point of his fate. Well, it will be decided per rules of the games. Kalbhusahan has already cooperated and didn't want the other treatment at all. He knew it since the day he started his journey as such. In my opinion, even he is alive till the natural death; he is a liability & a living example of Indian espionage in the region. If hanged, that will be in-fact done after due process and parties already knew the truth; will be satisfied further as well in view of legal procedure as well as evidences & proofs etc.
Question is: Are you (Pak nation) willing to see same treatment given to a pak spy? As per pak media, India has already kidnapped a former ISI man, and he is in india. Are you willing to see similar treatment to him?
Pakistan Nation has already seen much more worst treatment to the people booked on the false charges of espionage only to blame & malign. And not just that; they were eliminated so quickly and done within no time. If you are really interested to discuss with interest & facts; just don't ignore what has been happening. The so-called former ISI man you referred, was abducted from Nepal as compare to KJ arrested in Balochistan finally after watch of two years.
That Pakistani Retired Officer just landed, shared his picture from Air Port and then gone. The merit of the case such as abducted from Nepal as compare to arrested inside Pakistan after two years tailing, is incomparable however, the point of tit for tat can be discussed. Since we are discussing the swap thing; there is not a single chat about that. India cannot prove that Pakistani Official was arrested inside India or ever traveled India or any other documentary proof. Indian Agency abducted him only to put pressure on Pakistan & hand over the KJ. If you are going to ask question that why Pakistan didn't take the legal route for Pakistani Official being abducted in India; share me a single statement where India officially declared him arrested which strengthen the argument that it was merely to put pressure & for possible swap.
KJ is already compromised along with the whole team.
When Modi became PM, all this stupidity/naivety ended from India. India has been not been always reactive. I think this is what pak leadership is unable to digest.
What if the same is like India was undetected before but since an impatient yet angry/raging Modi came into power; he gave away a lot due to his grudge & enmity against Pakistan. There are several occasions & many of references that Modi has done far more better damage to India himself than the previous government. Since he can monger for war & killings; doesn't mean others find it appealing. Conclusively, he overly reacted and lost more face. However, since Indians are happy with the development; we are good with it.
As long as KY remains in your custody, that ISI guy will stay in India's custody.
Again, what is the proof or reference that the guy is in Indian Custody.
