I am more of a WW1 girl myself, but I will have a go! My answers are more to do with the perception we have of people's emotions and attitudes to the war, which I guess we gain from historians (and popular culture too).
For instance, the euphoria and relief felt by people in Britain and the USA when the atomic bombs were dropped on Japan. It's a horrible admission to make, that people were glad, but I do remember my mother telling me that she was pleased that the bombs were dropped and felt very little sympathy for those killed. She was simply glad that the war would end and viewed the Japanese as getting their just reward.
To put this in context, my family lived in Bristol during the war - an incendiary bomb had landed on my mother's bed, luckily she wasn't in it at the time! I think with the benefit of hindsight we tend to feel guilty and shamed by the atom bombs (and that is understandable).
We also tend to think that those living in Britain during the Blitz must have been frightened, deprived and unhappy. My father, who was five when war broke out, loved it - he thinks the war years were the best of his life. Adults were preoccupied, teachers away at the Front and he lots of freedom and found the Blitz exciting. Sweets may have been in short supply (and he does have remarkably good teeth), but fun for my father at least was not. Again, not the received view.
So, that's my answer .... what do you think?
