This is either a victim of Russian propaganda, or an agent of Russian propaganda.
As to the presented ideas in the talk - as someone who knows Russia well, speaks Russian, has Russian family, he’s spot on - but no Russian will ever agree, because that is part of their complex.
Luckily for me, I did actually spent 1 hour watching the video (more like 4 hours in between managing kids) and it made sense of many things I didn't understand before. As somebody coming from country brutally occupied by russian forces for 21 years on a 'friendly special mission', yes the part about mentality is spot on.
I don't think Putin is on some holy mission for slav unification, seeing how he immediately ordered 10,000 chechen killers on their closest slavic neighbor. He is just an ordinary smart thug, highly functioning sociopath, who got lucky being at the right time and place and having good KGB experience to get him to the top and sustain.
Also, its a great lecture on how to not even react and completely ignore the russian news full of 'pravda', intended to just divert attention from other nefarious activities purported by them. Don't play the games they lay for the west.
