It's a very astute observation - I feel like there's been a mix of arrogance, apathy, distracted behaviours/complacency in many countries and failing trust in our institutions for quite some time now (including state educations). Survivors from that era of time have all nearly died and not enough of their stories were recorded/made widely available, but instead we've had so many stupid films made that romanticise and glorify what happened (no wonder so many people don't realise the full extent of fascism in Europe; for many their first point of reference is a film). The communities still affected by the events of WW2 get silenced - I can't help but remember how many of my Jewish friends in school were spoken over by others and told that the 'Holocaust wasn't that bad' and that they 'should get over it' - which still makes me feel sick. Nowadays - in general - sadly most people don't read books or engage with their countries' histories; no wonder we haven't collectively learned from the lessons of our past. It's distressing
I studied history at uni quite a a while ago, and I think the most important module of any was the 'approaches to history' one in our 2nd year. At the time I wasn't that bothered about why Eric Hobsbawn used the word 'but' in a sentence, but looking back it was the most valuable thing I've ever learnt. We were taught to thoroughly understand
who was writing
what and
why. What sources they were using, their own biases, and what this told us about what they were saying. Different approaches such as marxism, post modernism, the alien ant theory of human behaviour. It should be compulsory, especially when there are so many conflicting and dangerous voices out there.
We also watched historical fims, and critiqued them like the little wankers we were. The inaccuracies in Ben Hur, war films, and why certain stories were told (Like your comment about the British view of WWII, and why the French feel very differently about Dunkirk, for example). The film that reduced everyone to silence, and the one film I'm glad I've seen but will never watch again? Come and See, about WWII and Belarus.
