I think, it is not hard to understand, that from the Russians point of view, it is of the utmost importance, that they create all around Russia sufficient buffer zones in order to secure Russian borders as much as possible.
They are very powerful country now! This gives them the means for securing all their borders!
I think they are not out for any wars: They just want to b e able to keep securing all their borders!
All people, that study history objectively, should find it obvious, why the Russians, with Putin as their leader, right now act the way they do!
Hasn’t the West fed them lie upon lie? I don’t see, why they should have any reason to trust us!
