It's interesting to see, although we don't take them one of ours and also, they are happy being Pakistani, their culture is still 70 % indic and will be even more if you rule out the religion.
What they've done over the 70 years is indianizing their iranic tribe like pashtun and baloch, and if that's not enough we are also fighting for influence over these two tribes, that's why you only hear free balochistan or free pashtuns from Indian side, not free Sindh or free Punjab.
You've got the crux of the civilizational battle being fought out.
Iran is too weak to fight back.
Plus Iran has a racial superiority thing over these two peoples, whove aleats been periphetal bloodlines ofotgeir empire''s eastern fringes, which modern day Indics do not suffer from.
