Professor John Mearsheimer of the realist school has some hour long lectures on the topic of Ukraine. Some even precede the war itself. Obviously as a disclaimer, I do not agree with everything he has to say. You can pick and choose which sources or interviewers better appeal to your partisan biases. I won't choose for you, as you might dismiss it based on the source. That said, he's spoken with everyone from Amy Goodman on "Democracy Now!" to the Hoover Institution.
You might consider how your framing of super weird Russian propaganda applies to his lectures and interviews.
