India is playing with fire because Pakistan doesn't have such a policy. If the situation appears dire for Pakistan, the Pakistani Army could resort to using tactical nukes.

Ah! So for Pakistan to be "playing with fire", India would merely need to withdraw it's stated "no first use of nukes" policy?

All you're doing is legitimizing a rouge state's rouge excuses for threats of nuclear war. Pakistani army has NO excuse to use nuclear weapons, unless they've been at the receiving end of a nuclear attack
