Book excerpt: For almost five decades, the United Kingdom made plans for a nuclear attack that never came. To help their citizens, civil servants, and armed forces prepare, those in power designed and published a variety of booklets, posters, and how-to guides. Most infamous among these was the Protect and Survive campaign, but just as fascinating are lesser-known materials prepared for the United Kingdom Warning and Monitoring Organisation and the Royal Observer Corps, many of which are reproduced here for the first time. From terrifying images issued by central government, to local councils' sometimes amateurish survival guides, 'Nuclear War in the UK' is a look at the way Britain's authorities reacted to the Soviet nuclear threat.
