You need to learn about history.
Every side during WWI were related.
The English the Russians the Germans their leaders were all literally cousins.
Pretty much all the banking families are the same, they all inbred.
They sank the Titanic to kill off all the rich people that wasn't part of their inbred family then consolidated their wealth.
They same few inbred families that have been in power since the fall of Rome
