Neo, India would welcome it as the level of desperation in your military planning can be seen that they seek to Tact nuke its own country to thwart advancing Indian corps. Any Tact Nuke lobbed on Indian forces by Pakistan, will cause India to let loose hell on Pakistan. The gravity of consequences of these childish threats, issued by Pak's loony military, is not understood by mostly deluded Pakistanis in their obsession about Jihad. And their own follies are breaking their country apart. Whereas in India, as it grows economically it has been able to push insurgencies to background to near irrelevance. And as employment grows uniformly in India, these will die down natural death. Unlike Pakistan, which is fighting with itself to prove who is more pure muslim.
Indian actions against Pakistan are more nuanced designed to expose Pakistan as threat to whole world and isolate you in long term. India does not believe Paki theory of killing enemy country's civilians to supposedly cow down it. India will force you diplomatically, to have your choices so limited that you will have to sell your sovereignty to another nation in order to seek protection. This way India ensures India talks to more rational counterpart, in order to have control on mad dog of the world.
India may show open concern about China making inroads in Pakistan. But internally India is happy, that Islam obsessed Pakistan will give more way to Godless Commie China.
