No...Indian doctrine ensure that paki nukes are just a show piece. Its pakis who are scared to use even their tactical pukes.
First, whatever Indian doctrine is, the quantity and quality of India's nuclear force is far below the level that make Pakistan's nukes a show piece. Only 2 countries have that capability: USA and Russia.
Second, Pakistan doesn't have tactical nukes. Again, the number of their warheads is too small to use as tactical weapon.
Then again India is a responsible nation with nukes and neighbors, so it wont cry of nuclear escalation unless there is a real escalation unlike your friend pak.
Again, except USA and Russia, there is no option of nuclear escalation for others. Either you shoot all your nukes, or you don't shoot at all.
India is claiming and proving paki hand in terrorism because pak has publicly many times acknowledged the use of terrorism as a tool against India.
With overwhelming superior force with commie china, china is claiming and crying about terrorism from East Turkestan.
Chinese doesn't hold a neighbour government responsible for the terrorism, but India does.
