My whole knowledge of the situation is a couple decent videos I watched when shit started hitting the fan. So, again (as people often get heated when it comes to politics), I'm not claiming deep knowledge here.

What stood out most to me, main takeaway that seems hard to argue with, was what seemed an objective timeline of NATO breaching agreements time after time by spreading closer. The other was the US-staged coup in 2014 in Ukraine.

That they feel seriously threatened seemed reasonable to me. Appropriate response is another thing, and I don't know enough about what efforts they made leading to attacking Ukraine, but surely plenty of noise.

That's as concise and accurate as I can manage, in my sleep deprived current state, of where I'm at on the bare bones of the situation.
