Gave you a "like" Allan. As a 50s-60s kid, I can't recall duck-and-cover, but do remember the town I lived in testing its air raid siren (haven't heard one of those since). Remember the Diefen-bunker, too. Younger readers could Google it.

But nuclear war was actually a "fun" movie narrative during that time, too. One that made an impact on me was Panic In Year Zero (Ray Milland) and the mainstream hit, On The Beach...haven't seen it in decades but still remember scenes from it (Wow! Horses-and-carriages because there's so little gas for cars!) 

 Cuba missiles was once a 60s page-one story. Yesterday, above-the-fold front pages, NY Times, LA Times and San Fran. Chronicle? Kneeling football players. N. Korea? Waaayyyy down at the bottom, one column, no pics.
