The biggest battle of WWII was NOT Stalingrad ( physically huge but intellectually a mere bun fight between History's worst dictators) but rather the battle over wartime penicillin : who makes it and who receives it.
For WWII definitely had a 'war within a war' aspect to it .
The billions of individuals who made up the modern global civilization of 1939 had six long - bloody - years to re-evaluate whether the
core values of their culture were really worth dying for, or were they only good for starting aggressive wars - but not the sort of values for ending aggressive wars and securing permanent peace.
The New York World's Fair of 1939 promised a total world of man-made-ness but in the case of penicillin, man-made-ness ended in abject failure and it was Mother Nature that brought us this wonder drug when Man proved to be 'not up for the job'.
The world of 1939 eugenically exalted the Big and the Mighty and denigrated the weak and the small : penicillin (once it was a perfectly pure crystal shining brighter than a thousand suns) would be distributed on strictly Darwinian lines.
It would not be made in such quantities that would require the Allies to make one less bomber or battleship : so it would have to be rationed and so would go only to the eugenically 1A people .
(Be they fighting in foreign combat lines or winning the war behind some important desk in London or Washington.)
But by 1945, those same bombers were being pulled off their jobs of riding shotgun over the NRA nation and converted into butterflies to deliver life-saving grams of Nature-made penicillin to the dying all over the world : regardless of age, color, gender and economic status.
1945 was indeed the year that baby "Baby Boomers" started entering a very new , ante-Modern world......
