What does Obama have in common with Reagan concerning nukes?

Yea, I'm pretty sure that everyone agrees that Nuclear war should never be fought. However they do serve as a deterrent and probably will prevent more death than they will ever cause. But that goes out the window if someone is ever stupid enough to use them. But you cannot eliminate them completly unless you can make sure that no one can ever build another one, because it's a pretty good bargaining chip.
