Why does India have a "no-first-use" policy for nuclear weapons? Shouldn't India strike before the damage is done, how practical is this policy?
Answer by Shashank Sharma:
Other answers have not covered one point, and that is the policy of Credible Nuclear Deterrence.
India maintains a nuclear arsenal which is ready to attack other nations at a moment's notice.
We have submarines armed with nuclear missiles, and are currently developing our own ICBM ( Agni V ).
As such, these are enough to not let the enemy even entertain the notion of attacking India, because aggressor states know fully well that wherever they are in the world, they'll not survive a nuclear attack from India.
That is the policy of Credible Nuclear Deterrence.
As far as being attacked first is concerned, we have Anti Ballistic Missile defenses in development!
