Very enlightening, thank you.
But, perhaps the original idea of right to return, might not be so workable, as clearly you cannot trust India. Besides it being controversial, the practicalities are impossible without Ernest peace.
Still, the idea has beauty, suppose that will have to suffice.
It's too late now ...
At one time the "Right of Return" would have produced an influx of a gold mine of scientific. journalist, and academic talent.
The generation that longed for the land of Pakistan despite being expelled from there is now gone.
What emotions their progeny have inherited and if their emotions have been transformed into an RSS mindset is unknown.
The post independent pre-cursor to the BJP in Delhi known as the Jan Sangh had a large following amongst the expat Pakistani origin Punjabi Hindus. Even though these Punjabi Hindus claimed to be Punjabis they in fact spoke Urdu ( or 90% Urdu with a few Sanskrit words), and had their own Urdu newspapers (
Milap,
Pratap,
Om ).
They enjoyed a peculiar relationship with the residual impoverished ghetto dwelling Muslims of Old Delhi, to whom they offered employment in their small businesses.
Only a section of displaced Hindus resident in Delhi were Jan Sangh sympathizers. There were many who despite being refugees spent their entire life campaigning for better ties with Pakistan.
Noted journalist Kuldip Nayyar went to the border on 60th anniversary of Partition calling out to curious Pakistanis gathered on the other side behind the barbed wire fence in the local Punjabi dialect that he was one of them.
There were others like Khushwant Singh who spoke up for stranded Pakistanis in Bangladesh and interviewed Gen. Tikka Khan to get his side of the story.
In the movie industry you had Shashi Kapoor who acted as "Rizwan" in the movie
Jinnah .
There were military officers like Lt. Gen. M.L.Chibber who after fighting against Pakistan all his life visited the land he was born and raised in desperately hoping to maintain some connection.
It's too late now...
Looking to the past is futile.
On a different Pakistani defense website an expat Pakistani Hindu wrote this famous couplet from Ghalib.
Wa ke nahin pe wa ke nikale hue to hain,
Kaaba se in buton ko bhi nisbat hai door ki"
" Though not belonging there, but expelled...
These idols also have a distant connection to the Kaaba "
