His pre invasion speech has striking similarity to Hitler's speeches

I find this take very reductive. I would rather see something more concrete like:

Putin's pre invasion speech has a striking amount of blood and soil rhetoric. And in addition just like Hitler he denies the right of existence of East European states between Germany and Russia.

Well he did all of that too. He brought up "grievances" going back almost to the 1800s. He denied that Ukraine and other Eastern European countries were real countries. He said that Lenin and Stalin were too soft.

He all but said that controlling these countries was Russia's "Manifest Destiny".

And he had a lot of yap about history, like Hitler's "historical necessity" and "world-historical" rhetoric.
