Goddamit Vladdy, I thought we're partitioning Ukraine any day now!

So I watched/listened the Putin interview by Tucker Carlson. It was long and boring, and basically he reiterated the same things he usually talks about.
Here's Michael Rossi's channel (of Rutgers), he translates speeches and interviews and appearences and whatnot from Putin (and Lavrov):

I think in the Results of the Year videos Putin covers some of the points. At least the little I watched from those I noticed some overlaps.
Anyway it was very comprehensive, they were talking (well mostly Putin) about all kinds of stuff.

The only question I still haven't heard an answer to is:
>Why did he invade Ukraine?
