To think nuclear arsenals are acceptable is to wager that they will not be used in warfare. It is taking a bet that we're crazy enough to threaten the use of them but to never actually use them. History shows that we have been on the verge of nuclear annihilation time and time again during the cold war. There were multiple times where it came down to one man on whether or not they were to be used. Nuclear weapons are no longer needed to deter war, now there are missiles that can hit a fly on a doorknob from 500 miles away. The possession of nuclear weapons should be considered a crime against humanity.
