Anyone with even cursory knowledge of such systems knows that BMD can be beaten with ease (by a country with even rudimentary missile program)...... furthermore, geographic location of Pakistan and India, and the fact that any such systems will be mated with nuclear warheads and accuracy of such systems being least of the problem, and assured mutual destruction in case of a strike, makes Indian BMD systems pointless vis a vis Pakistan...... Pakistan, at least for the foreseeable future has nothing to worry about, as Pakistan is no Gaza and India is no Israel.
Only thing Indian BMD is good for is, protection of certain strategic locations, that too to a degree..... it's no "iron dome", heck, even iron-dome isn't iron-dome!
where do you suppose to fire missiles ? strategic locations only. as per vienna convention you can't target civilian population.
