The UK and Ireland would be “Judenrein”.
We would be speaking German.
The Church of England is gone.
Berlin would be the political/cultural centre of our world.
There would be Tax Incentives (and land grabs) to move to Siberia.
We would be trying to make peace with USA after the 3rd World War.
If our babies weren’t blond and blue eyed, we could terminate the pregnancy.
If our babies were disabled, they would be killed.
There would be a Slave culture, with Poles being of more worth then Belorussians, etc.
I could go on but none of it is good 🙁
