> The moment Pakistan's military stops its terror funding and support activities, India will not care whether it Pakistan lives or dies
I'll entertain this is possible. But it's not only unlikely but irrational so long as Pakistan deepens its ties with China. It's made almost certain by the attitude you're presenting: countries that do "not care whether" their neighbours live or die generally aren't on peaceful terms with them.
Really? How do you know. Most Indians don't care about what happens to Pakistan or its people.
The moment Pakistan's military stops its terror funding and support activities, India will not care whether it Pakistan lives or dies.
