I feel like it must have been so overwhelming yet intangible - in some ways a nuclear holocaust is much less painful than losing a loved one in a car accident or seeing your country splinter into violent factions. A nuclear holocaust is a quick, binary event - either it happens, or it doesn't.
I also can't imagine what the fear of being drafted into a WWII or Vietnam War situation would feel like.
Would love to hear what anyone with experience has to say about those "ages" of fear relative to this new one of mass-media/technology-produced fear.
