If Fred Bridgham had to survive off of writing about WWII's "Clash of Cultures", the poor bugger would quickly starve to death.
There simply wasn't any - not at the nation to nation level anyway.
And don't talk to me of Hitler and Stalin - the two admired each other as much as they hated each other - they understood each other.
Instead WWII's real ideological clash occurred almost as 'noises off' - buried within the little known race to produce D-Day's penicillin.
Would it be "The Smartest Chemists in the Universe", assembled in dozens of Allied labs and swaddled in money and resources, convinced that as a result synthetic penicillin would now be a piece of cake ?
Or would it be crude natural penicillin made by the despised basement Slime - old and slow and small and dumb ?
We did mention 'dumb', didn't we ?
If PROGRESS (all bow) meant anything at all, it certainly meant that university-educated Man could create better, cheaper, faster penicillin than the Slime ever could.
(For 'slime' , feel free to substitute Negro, Oriental, Homosexual, Woman, Unfit, etc.)
Except Man couldn't (and still hasn't !) - and from then on the Path of Progress, as the doctors say, took an irreversible downhill course......
