fair enough - what about the UN peacekeeper mission for india / pak (UNMOGIP) - ask them to make a low key investigation. that should suffice.
Again, any involvement of third party is what India don't want.
If you have seen that interview of Jaswant Singh and Pervez Mushraff, they said India and Pakistan were close to a solution on Kashmir Issue WITHOUT any third party involvement.
See point is, its domino effect, once UN is introduced at low key level, it could be built up as major international issue by effective diplomacy.
If you remember Pakistan has recently raised Kashmir issue in UN saying that UN has failed to address this issue and no one noticed it. If now UN in involved at slightest bit, Pakistan can use it as a reference point.
Both you ane me not that, Kashmir issue on multilateral dialogue will never reach any conclusion. Only bilateral solution is possible.
And sorry to say that, both in India and Pakistan, there are factions who don't want this issue to be resolved. Kashmir issue has been a Golden Goose for these factions.
Recent PEW survey said that majority of Pakistanis think we should make peace with India and focus more on other issues. Similar is the case with Indians. Kashmir has lost its charm. If you look at 2001 onwards, reduce in insurgencies and even attack of 26/11 being forgotten so easily and lost in midst of anti-Corruption, rape, etc, issues, Indians don't think about Kashmir that much either.
Both Indians and Pakistanis are getting used to of status quo. Our next generation may not even know what was it like during 1990s and 2000s when terrorism was at its peak in India and Pakistan respectively.
I mean, social media has brought both India and Pakistan moire closer, even if we fight, at least we listen to each other's posts. At least general population are now interacting through direct conversation, they don't get all information from state controlled media. No Doordarshan or PTV.
Consider this situation from a social scientist's POV. You will see that our grandfather wouldn't have thought we will be talking with each other and sharing jokes with some one whom we call Enemy No. 1.
No matter how much we deny this, Indians and Pakistanis are getting to know about each other and they are seeing that general population have same problems, Corruption, Poverty, Hunger, Electricity, Diseases, etc. is far more important for both than Kashmir.
