Penicillin : from Modern to ante-Modern in six bloody years

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 .

Roof and Rhetoric share a word sense

Stalingrad's bubble

Just as a roof shields us from the reality of the external world - allowing us to live in our own physical bubble, so rhetoric can convince us that the facts of physical reality don't exist - even outside our physical bubble.

The high school teachers of WWII's leaders, got THEIR high school education back in the Early Victorian era

MY high school teachers ran WWII !

It is striking how just old the leaders of WWII were: not just politicians, but also the generals, bureaucrats, CEOs, professors and editors. Anyone who was anybody was usually far older than today's leaders is in equivalent positions.
