Maybe you're right. I honestly don't know. But I only have so much time in a day to veryfy everything. I'm talking from memory of course, but this Ukraine invasion didn't "come out of the blue" AFAIK.
Here's a collection of sources compiled by someone on Quora. I dont know how biased or accurate this person is. However, there were other instances that made me think this isn't so black-and-white or "clean" as I'd like it to be.

A lot of the sources he used are from Ukranian websites so you might need to run them through Google Translate. Some are from reputable (for at least some definition of reputable) western media outlets like CNN, BBC, NYT, etc.
The embedded vidoes don't seem to work in Chrome (they just disappear when I click them) so I've extracted the link for one of them here:
https://www.youtube.com/watch?v=JrMiSQAGOS4 - Why is Ukraine the West's Fault? Featuring John Mearsheimer, uploaded by The University of Chicago
Other videos are shorter clips to prove a point, but if anyone's interested they can see the video ID in the embedded image URL when inspecting the element.
Again, maybe this is all dogshit like you say, but I find that too dismissive of the facts presented.
