Protect and Survive was a British government civil defence campaign from the 1970s, created as a series of short public information films explaining what households should do if a nuclear attack threatened. The films were never shown as routine television, which only added to their notoriety when they later became widely known through broadcasts and documentaries. Their cold, instructional style has since been parodied and sampled in music, comedy and online edits, where the title alone signals approaching catastrophe and gives a modern joke an unsettling Cold War flavour.
