While chinese icbm can easily cover our entire land mass. With all our nukes we can destroy only 0.5% of china. But their capability of 400 to 500 warheads some with 25 giga tons of power can wipe off 5% of our land mass. So we need a missile defence shield to deter any chinese aggression. the above taken from a reply to one of my threads any comments please ?? in particular if the nation is increasing production of missiles and nuke warheads ??
