I think it’s a dictator trying to create a legacy of greater Russia.
Hasn’t that been the case throughout history. Russia, Britain, Germany and going back Greece, France, Assyrian, Turkish, etc etc
In fact its quite a list. Running into hundreds, from 4500BC right up to the Nazis in 1933.
So I don’t think it’s ever going to end. there will always be someone who sees their country as the one which should run the show, who knows best. But history has shown they never last.
Some like the first Mexican empire only lasted 2 years, while others like Sumeria lasted 2600 years.
