No, you really couldn’t. You could come up with all sorts of reasons for disliking them, or wanting to harm them, but that’s not the same as a reason for expending the huge economic, military and human cost of invading them. To invade a country you have to be willing to pay the price of doing it. Nobody has a good reason to want to pay the price of invading Pakistan. Not even India.

That could change, sure, but that’s not the situation as it stands, and if you can’t see how that works, I’m not sure how I can help you get there.
