It would be nothing new for us - merely a matter of degrees of difference. We already know what we fight.
You have then failed to read how we see you.
We don't find Pakistan very different from ISIS. A milder version no doubt, but that of ISIS, which is slowly increasing its tempo in radicalization. Right from 80's uptil now, Pakistan and Pakistanis are growing more and more ISIS like.
We see the Pakistanis jumping the LoC to kill civilians in Kashmir as nothing other than the jihadis of ISIS and support to those who explode in markets as those having the Pakistani ideology.
Those of our previous generations did have a favourable view of Pakistan and most importantly Pakistanis for a variety of reasons. They made a difference between the state of Pakistan and the people of Pakistan. And they liked Pakistanis and reserved their dislike for Pakistani Army/govt.
The new generations see Pakistanis as nothing but a continuation of the ideology of terror. As the old timers are being replaced from leadership positions in India, the shift in governmental attitudes - that of steadily hardening/hostile positions is simply a reflection of our society and what we see you as.
