The sikhs are not the masters of their own destiny at this time---. Once they become the masters of their fate---the decisions made at that time would determine their true future---.
Once east punjab becomes free---the and lock of east punjab may not hold for long---there will be a paradigm shift in the geography of hindustan---.
And there is a very good possibility that hindustan rather setting Khalistan free would rather see it destroyed---.
The sikhs have momentum building on their side---this is a 100 years opportunity---let us see how they avail of it-
Sir India is a country of 1300 Million, Sikhs are just 20 Million and not all of them wants Khalistan. Even back in the 80's when that movement had a widespread acceptance in Sikh community chances of its success were limited. And India has changed since then. Its no longer a sick economy lagging behind rest of the world but in fact is one of the fastest growing economies of the world. What benefit is there for Sikhs to seceded from such a state.
There can be many reasons why an ethnic group will want to secede from a multi-ethnic union.
1) They feel their identity is under threat
2) They feel they will gain economic freedom resulting in more opportunities for their people.
I don't think either of these conditions are true for Sikhs right now, but let's assume for argument sake that Sikh identity is under threat and they can economically benefit from a separate state. So would India just accept their demands and give them their freedom or would it crush it like it did back in 80's. The answer is of course India will crush it.
East Punjab has a population of 27 Million. Sikhs make around 60 percent of that so it will be 16 Million. Even if all 16 Million of them want freedom how difficult do you think it will be for a state of the size of India to crush such a rebellion.
The only way it is possible is with foreign intervention. Now none of the western countries will get involved, India is their ally. China would not militarily intervene. So that leaves Pakistan. Do you sincerely believe that even if PAF would have been in a position to take on IAF, we as a country are capable of an East Pakistan style intervention? No we are not.
So this is a lost cause.
And besides, India provides Sikhs with a lot more opportunities than a separate state ever will. This is the same reason why Pushtunistan movement never got much support within Pushtuns because they understand that staying within the federation provides them with a better life than having a separate state or forming a union with war-torn Afghanistan. The day Pakistan became economically un-viable vis a vis Afghanistan, we'll see such movements getting much more support.
The only way I see India breaking down is if there is an economic meltdown and one or a few of the larger Indian states decide to go their own way. It can be UP, Bihar, Maharashtra, Bengal or Southern States like Tamil Nadu, Andhra, Karnatka and Kerala as a block.
Now UP, Bihar and Maharshtra are ultra nationalistic so I don't think a case can be built there even with an economic meltdown. But Southern states($2500-$3000 per capita) can see Bihar($800 per capita) and UP($1000 per capita) as a burden that is dragging them down. This along with the North-South linguistic and cultural divide can cause the Southern states to quit the union. That will be next to impossible for an economically weak India to stop.
But currently this seems just a pipe-dream nothing else, but I assure you sir this pipe-dream has more chances of becoming a reality than E.Punjab and Sikhs gaining freedom from India.
