India and Pakistan’s Proxy War in Afghanistan | The Diplomat
Now towards your self asserted points
Where is the source
For points 1-3)As is the case with every disputed land both contestant needs to withdraw and let world body like UN take control and conduct a referendum.
Kashmir being part of India was against the soul of the partition as Kashmir was and still is more than 90% Muslims majority areas and was supposed to be part of Pakistan as per the rules under which the division was done.
Now if you think Kashmir would have been more peaceful under India you are just delusional .The current state if Indain held Kashmir and Pakistan held Kashmir clearly shows whose dominated Kashmir is peaceful and progressing and is the answer to your assumptions which doesn't support ground realities.
Besides how Muslims are killed for the sake of Cows in larger India and how your mega stars from SRK , Salman khan and amir khan are voicing their concerns over exploding intolerance in India clearly shows its not about Kashmir alone time is not far when Muslims in India would be carving away another big chunk of indian land to live peacefully as per their own custom and religion.
