Try googling a popular UK site e.g. "millennials site:www.bbc.co.uk" and you'll there's been plenty of articles over the years.
Time to join the internet generation :)
(although you'll also see generational articles in the UK's dead tree news)
But that seems a rather broad brush to be slapping around so I'm sure it's largely unfair.
It was also the most heavily propaganda-oriented thing in living memory. Y'know all them John Wayne war movies? Yep.
The classic propaganda movie is best exemplified by "Sergeant York". The scene where the dapper officer explains the conflict between "Thou Shalt Not Kill" and "Duty, Honor, Country" is exactly how propaganda works. "Well, it's not killing if they're Huns."
I always thought "The Best Years of Our Lives" exposed the more sinister aspects of the war experience ( it describes PTSD decades before the concept existed beyond "shell shock" or "battle fatigue" ) , and it's interesting that my favorite authors were either outsiders ( like Saul Bellow or Phillip Roth), pop historians ( Michener ) or those who went through the war as dogfaces ( Heller, Vonnnegut ).
I'm not sure where you're going with the propaganda films as compared to my point.
But I agree, the Great Depression would be a contributing factor to what I'm describing.
The propaganda made the Boomers uncomfortable. I've made somewhat of a study of Sixties literature; I don't think it would have been that way if it were not for WWII propaganda. The WWII propaganda is also quite out of character for Americans historically. Even with the curtailment of basic freedom of speech in the Civil War, plenty of people were on Lincoln heavily the whole time.
FDR was all but immune from even criticism.
This propaganda changed the American character a great deal. I had two grandmothers from the pre-WWII period and they thought differently than people do now.
I think the Depression was the principal cause of WWII.
