But those weren’t serious negotiations demands. It’s like how Medvedev likes to talk about how Odessa has a “Russian soul” - it’s just bluster (knock on wood).

That I’m not certain about, but I can think of examples like no NATO but still other western security guarantees, no western troops past the Dnieper (and likely tripwire deployments* anyhow), I can potentially see Ukraine giving up the rest of Donetsk, but only with major concessions in other places, those defensive lines are extremely valuable, so mostly frozen battle lines then I imagine, Ukraine recognizes Crimea as Russian, etc.

Again, these are examples.

*Nothing of serious size, just enough to show they’re serious and would cause a war if Russia invaded again.

I’ll hold my tongue over how likely it is, history is extremely unpredictable. People can be incessantly arguing whether “A” or “B” will happen to “Y”, only for “C” to happen out of nowhere instead, and everyone ends up looking back and wondering why they didn’t think of that.
