Stockpile numbers of all kinds of nuclear weapons is primarily based on the premise that official figures are correct. Sure they "say" they have cut
down on them, dismantles, removed from service etc etc, but lets be realistic, national security (of any country) is not called "national security
for nothing, they are hardly going to be honest and completely upfront about how many and what kind of weapons they really have in ready are they.
You dont spents years since cold war time and billions only to get rid of weapons because the other side says they have/will. cold war paranoia is not
dead by any stretch.
Im betting the real figures are much higher than the official blurb.
Those who "play down" the effects of global thermonuclear war, imo, are fooling themselves into a false sense of security. That said , theres bugger
all any of us can do about it anyway, but beleiving official figures because they are "official" is laughable.
