"We never did any "duck and cover" in Finland during those years, how about Britain?."
Not in my city in England.
I don't remember any Junior School lessons about politics or even history. Secondary School "Social and Economic" history for "O" Level examinations stopped short of even WWI - and wars in general were a minor side issue about their effect on economics. Our junior Physics teacher had been a submariner - and was easily led into reminiscences if we became too bored. Nothing particularly about the war as such though.
I don't remember being particularly concerned about a nuclear strike. For most post-war born kids WWII seemed very distant - only 12 years after the end. Kids lapped up the excitement of things like the TV documentary series "War At Sea".
Even gaps in the rows of houses left from occasional single bomber raiders were regarded as not particularly remarkable. The local army reserves had their Drill Hall at the end of the street. It was an event to see their armoured convoy going out probably once a year - leaving tank track marks on the streets and main roads.
In the 1960s air shows featured state-of-the-art jets like the EE Lightning - which we took as a technological marvel rather than an expression of defence necessity.
BBC TV had a very scary children's drama serial about children in the Warsaw Ghetto. I remember it was many years later before I realised it was "Warsaw" in Poland - not nearby Walsall down the road.
As a pre-teen in the 1950s I did have sleepless nights worrying about catching polio after the very scary Ministry of information film on TV.
In the 1960s my father was in the Civil Defence Corps that was supposed to do something to help their local populations in the event of a nuclear strike. Basically the same as the old WWII Air Raid Wardens - but with no chance of being particularly effective if they were ever deployed.
My father was a shift worker so missed at least one in three weekly training meetings. He was still awarded his "qualified" certificate.
Apparently disbanded in 1968 - probably when someone decided it was a waste of money.
