We had this conflict before 47 and we separated.
Now we have some issues
on top of it is invasion of Country of KASHMIR by India and its state terrorism against Kashmiris.
2. We have been facing Indian state terrorism since many decades. The Indian state terrorism against Pakistan in 71 is the biggest driver for our lack of trust in India forever.
3. Indian state support to BLA terrorists.
4. Indian aggression against Pakistan at every level ranging from our defence purchases to sports.
We can be ok with the rest of Indian aggressions but Kashmir issue we can not ignore.
So the bottom line is surely we have NO religious issue with India currently rather the Hindu-Muslim issue is within India itself and call for second Two-Nation theory.
