Gut flora suppositories are a thing, and have been since before WW2.
Seems there was a guy in WW2 with golden guts, who survived the trenches and bad food, dysentery and such unscathed. Doctors then took samples of his gut biome and started using them to treat others who were less fortunate. Like Hitler with his life long chronic flatulence problems.
These days you can take a simple pill that’s designed to open up once it reaches the large intestine the long way, rather than the shortcut. It’s sold under the brand name Mutaflor, but it’s the same stuff, just freeze dried and encapsulated for oral consumption.
Banana Republics come to mind. But during the time frame the US was doing that, Most of Europe was still doing their own colonialisms.
It was only when Hitler brought colonialism back to Europe that they started to wake up to how bad it was. Well, some of them. France and England had to start losing colonial wars, mostly due to losses suffered in due to WW2, before they slowly started freeing colonies.
Just shows that everyone is shit, and cheering for a team is kind of stupid.
