but according to UN it has to be included in plebiscite whole area is disputed
The UN has failed to do anything; they are irrelevant in this issue.
Even so; it seems Pakistan would easily win.
Here are the populations of each regions;
India
Kashmir Valley: 6 million
Jammu: 5 million
Pakistan
Azad Kashmir: 5 million
Gilgit-Baltistan: 2 million
The plebiscite would be determined by religion mostly. Most Muslims will either opt to join Pakistan or Independence - while most Hindus would opt to join India.
Kashmir Valley would be divided on whether to join Pakistan or become an independant state; most will go for independance but a significant minority will support Pakistan.
Jammu is a Hindu majority region and the inhabitants will mostly support India; but it also has a 30% Muslim population who would either go for independence or join Pakistan.
The people of Azad Kashmir and Gilgit-Baltistan are rock hard loyalists and will definitely root for Pakistan; however there will be a small minority of people going for independance.
Under these factors; Pakistan will most likely win the plebiscite but with a small margin.
My personal belief is that Kashmir should cede to Pakistan while Jammu and Ladakh to remain in India.
Your post is wrong fundamentally and on many counts.
According to the law of the land, no one but a person born in Kashmir may own land there. It is their land only.
This is sanctified and sealed within the Indian Constitution, which is what makes us a state in the first place. Your personal opinion does not count a dam.
There is no question of asking any Kashmiri to leave his or her land and go elsewhere because they are dissatisfied with the way things are run. It is their right to express their feelings short of violence.
Anyone, Kashmiri or infiltrator, who takes to violence is liable to be apprehended and tried, with the use of force, and with the possibility that the use of force will lead to injury or death.
Agreed ; violence should not be an option.
People resort to violence when they feel their demands are not being met; it's of a way of gaining recognition and more attention for the demands.
I doubt the violence will end until both Pakistan and India resolve this diplomatically.
