Earlier quoted context omitted.
I suggest you watch this John Mearsheimer talk (2015) as I think it will help clear a lot of misconceptions you seem to have and also tighten your thinking about the matter. If there's gonna be a WW3, it'll be because the West wants a WW3. [2015] https://www.youtube.com/watch?v=JrMiSQAGOS4
I've never found Mearsheimer's arguments on Ukraine all that convincing. I really liked Adam Roberts succinct take down in the Economist a couple weeks ago. I know Roberts doesn't address all Mearsheimer's points, but he hits the main ones https://www.economist.com/by-invitation/2022/03/26/sir-adam-...
Take this part:
"These factors suggest that the 2008 proposal to expand NATO to include Georgia and Ukraine is just one among many developments that have made the current crisis so acute. It is arguable, indeed likely, that the NATO expansion proposal made matters worse, as may some other Western actions, but to assert that “the West is principally responsible for the Ukrainian crisis” goes too far."
Or this gem:
"It’s questionable whether Mr Putin was right to say NATO posed a threat to Russia’s sphere of influence. From the start in 2008 there were different interpretations of what was meant by “will become members”. "
Putin made it very very clear where he stood, and yet you still see armchair psychoanalysis being done. It's all pretty shoddy. There is certainly nothing of substance here that even begins to address Mearsheimer's iron-clad arguments.
