When you get the chance to listen to a smart person with relevant experience, you should take it. The exemplar in this case is Chas Freeman, the interviewee in the video. Wikipedia has an article about him where you can learn something of his background.
I suppose Mr. Freeman might be a Putin puppet, but I doubt it. I disagree with him that Putin has made substantial mistakes in invading Ukraine, but I am eager to promote many of his other observations on the Ukraine crisis. Hence the sharing of this video.
On the question of Putin’s substantial mistakes, I say time will tell.
