it means the following - the real history of Europe is a tightly kept secret

the current inhabitants of Europe are recent invaders who arrived by sea
the cathedrals were not built by Frenchmen
the people that now inhabit Eastern Europe used to inhabit all of Eurasia

what you see on that map is the male lineage that invaded Europe no more than 250 years ago
when they arrived, the Ashkenazim were along for the ride - and they settled in what history books call "Polish-Lithuanian Commonwealth"

there is evidence to back up what I'm saying

Can you give more information. I though AshkeNAZIs came from the former Soviet Union.

What did Franco mean by the 'uninvited strangers'? Reptilian shapeshifters?

Here's the story I was able to piece together

The people now known as Balto-Slavs (the term itself was invented in 1848, so it's anachronic) used to inhabit pretty much all of Eurasia.
A single unified culture.

And then the invaders arrived.
The origin is unknown, the year is uncertain - but I'd guess it's around 1800.
Maybe it was 1812.

The inhabitants of Western and Central Europe were outright kiled or deported to Eastern Europe.
And the people who call themselves "deutches" established a Reich (literally means "realm") in Eastern Europe - in history it's known as "Catherine the Great's Russia" (the term "Russia" is likewise anachronic)

But the Brits had other designs, so they assembled an international coalition and attacked this Reich from all sides - the event is known as the Crimean War.

The Ashkenazim were part of this invasion - when the Germans settled Eastern Europe in great numbers, they were there.

That's why people think of them as having Eastern European origins.
