Eventually a nuclear weapon(s) is going to be used again. Let us only hope that it is not on our soil.
Some are sure to be used because they were built with belligerent intent. If they had a purpose such as balancing a specific enemy stockpile they might never be used, but when the enemy is diffuse and balance is not possible some will be used. The danger is that the big stockpiles might be drawn in even though no one wants that.
