You don't have to prove anything but you cant expect anyone to take the Indian perspective seriously when there is little to back it up other than hearsay or events commited under military rule 6 decades ago. Please link this study that you talk about, all I can find is Indian based sources which is of course untrustworthy regarding Kashmir or Pakistan.
I came across this years ago, and am not making a legal case. Still, I will try to find it. Even if I do, I doubt very strongly that it will change your views in the slightest. After all, it is open to you, as it is to anyone with freedom to travel within Pakistan, to check this for themselves.
You won't check, no other person able to check will check, largely because you don't want to know.
As far as the sources that you use - there is an example of the kind of gross error that they make just down below - I admire your confidence that they are any more authentic, rather than being reflections of frozen pre-dispositions.
I find it hard to believe that in 2022, with over 600,000 troops posted on the border and countless security checkpoints and technology that there is still no evidence of anything that India claims.
First, you should find it hard to believe that figure of 600,000. What do you think the Indian Army does for a living? The total strength is 1.2 million; I am sick of this half-baked assertion cropping up again and again and again, ironically from people who insist that my sources are wrong, theirs is right.
Here is the order of battle, provided by
@Signalian (it is to be hoped that you know who he is, and what his reliability of information is):
XIV Corps - Leh
3 Infantry Division - Trishul - Leh
8 Mountain Division - Forever in Ops - Dras
121 (I) Infantry Brigade - Kargil Brigade - Kargil
102 (I) Infantry Brigade - Siachen Brigade - Partapur
118 (I) Infantry Brigade - Parashu - Nyoma
254 (I) Armoured Brigade - Snow Leopard - Leh
XV Chinar Corps - Srinagar
19 Infantry Division - Dagger - Baramulla
28 Infantry Division - Vajr - Gurez
You may notice that exactly TWO (2) infantry divisions are located within the Vale. Even including ALL the formations facing the PLA in east Ladakh (at that time of writing, 3 Infantry Division, 118 Independent Infantry and 254 Independent Armoured Brigade - all expansion due to the recent PLA pressure is on the locations facing the PLA).
There are another 50 formations of the Rashtriya Rifles, specialised in counter-insurgency; that is another 50,000 troops.
We are talking of 80,000 troops in the Vale, counting all the Rashtriya Rifle formations as being in the Vale - they are not - another perhaps 20,000 in the Dras-Kargil region. Please do the arithmetic yourself.
I cite this example as an instance of the hot air that flows around these discussions, with not the slightest effort, nor the slightest intention of getting correct data.
I also find it hard to believe that alleged infiltrators would carry blatantly incriminating or useless things such as currency, passports, or Pakistan only products, as they commit these actions.
It is better you check your own accounts, in the Punjab, and the wide-spread comments of Pakistani posts. Presumably these are loyal Pakistanis, not planted to give flesh to a mythical Indian case.
Very simply by relaxing the ridiculous steps taken in recent days.
The Kashmiri man in the street is fed up of leading a constrained life because of a right-wing autocracy that is in power in New Delhi.
If we treat the citizen in Kashmir exactly as we treat our citizens in Bengal, or in Telangana, it is my firm belief that 90% of the discontent will die down, and disappear. I will not go further than this level of mention, since the more detail that is supplied, the more objections of a wholly disputatious nature will be bred.
The most humane thing is to provide the Kashmiris with the right to determine their futures. That can only be done through direct democracy, which Pakistan favours as per the UN resolution.
Pakistan favours many things. The Union of India might not agree on all of these.
The Indian stance is that Kashmir is ours because some unelected Hindu ruler said so at the very last minute while under duress, but oh please ignore Junagadh and Hyderabad because suddenly what the ruler decides is no longer important.
On Junagadh, the clear understanding that was provided well in advance about the need for geographical contiguity was violated. On Hyderabad, at the time of independence, the effort was to try and set up a third Dominion, and was explicitly vetoed by the suzerain power. It was later that the red herring of acceding to Pakistan was floated, and even Mr. Jinnah did not support it.
So other than a determination to prove themselves right and everybody else wrong can justify either of these.
I suggest you contact the other member, M. Sarmad, with whom there are on record in PDF extensive discussions on these precise topics. It is regrettable that they had not come to your attention earlier.
That is the essence. Consequence is that hostility will stay and keep on simmering, till the time circumstances, which are substantially compelling, offer a resolution. Till that time peace in this region is a pipe dream and, of course, we are bound to live this menace.
We might start by deciding a reconciliation strategy. A fond wish without a strategy will remain just a pain in the elbow.
This strategy could be to start with the outliers. Find the extreme examples, and decide to either deal with them, or decide to leave them alone until the less controversial matters are dealt with.
When we deal with a mountain of debt - I realise that with most of those reading this, it is an unfamiliar situation - what do we do? Biggest first, or smallest first? The answer will show us that it is possible to proceed, that it may take time, that if the wish is there, the solution will emerge.
