Greivances in India aren't separatist in nature except in some pockets in the North East.Wouldn't you agree that there are many grievances in India and they can be exploited? Maybe a little fact like 200 milions of Muslims who in many areas consist majority? You it is all fine to have ambition, dreams and you can think what you can do and what expect from that. There are 2 facts though 1 can you do it , very unlikely, you got to be logical here. You can find temporary alliance but it doesn't mean that Balochs dislike you less then Pakistanis. British could often do it and you don't have that mind, British ain't dreamers.
2 If you play that unlikely card , well realistically Pakistan has much bigger and more realistic card then you. As as I can see Pakistanis are pretty good at it and that card will always have more loyalty to them then yours for you.
Didn't you get any lessons from Afghanistan.
I honestly think that if you want something good for yourself that you should play things differently.
This is really friendly advice
To exploit any grievances, you need resources. To deploy resources, you need money. Pakistan is nearly bankrupt.
No one cares whether separatist Baloch or Sindhis like India. It is irrelevant.
