Listen keyboard warrior, a nuclear war with your next door is not a joke. Once you press the trigger, their is no going back and consequences can be significant. Indian ABM systems are in testing phase, and nowhere close to be operational. Why do you think that India wants to purchase S-400 systems from Russia? Talk tough when you will have credibility in this spectrum. Also, keep in mind that China is always willing to help Pakistan in the matter of its defenses. China might be willing to supply Pakistan HQ-9 systems, if necessary.
