“So, do you feel lucky regarding the above numbers?”
Those numbers are meaningless because no one will survive an all-out nuclear war, except perhaps for some primitive tribe somewhere in the Amazon jungle or on some remote Pacific Island. Those who were not killed in the blasts will end up envying those who were.
Sorry, but that was an answer during the Cold War, when stockpiles were 10 times as much. Things are different now, hence the updated information for you.
