After the Hiroshima bomb, a certain innocence was lost to the world. When we realized that we could create something so small that could destroy so many and devastate the land for generations, a shadow was cast over the world. Every generation that came after Hiroshima grew up in that shadow; the innocence we lost then can never be regained.
Mom made a similar comment about the children in her current 2nd grade class, because these are post-9/11 kids. They don't know a world without terrorism. She thinks it's something that permanently altered the national psyche, whereas I am more inclined to believe it isn't a new thing, more of a return to the years of the Red Scare and the Cold War. My age group were the anomaly in that we grew up without any serious fear of the rest of the world.
I dunno. What do you think?
