It’s not clear whether the timing of the publication of South Yorkshire and Nuclear War: Information for the Public in the County of South Yorkshire was simply a big coincidence, or a well-planned strategy. The latter scenario is entirely possible; the local authority had already made a name for itself nationally for its extreme (for the UK) left-wing leanings, so piggybacking on Threads to deliver an extra blow to the Conservative government and its strong belief in Civil Defence is not out of the question. >
