My generation has not grown to fear the bombs as the previous generation did. When someone of my generation is behind the buttons, I wonder if somewhere in the back of their minds there isn't a part of them that says 'perhaps in this and this situation it'd be okay to press the big red button?'.
I think the horror that war/these weapons cause will slowly drift from collective memory in mainstream western society. The warnings of the previous generation will be an endorsement of the destructive power of these weapons, instead of a deterrent of their usage.
