Jeff Rich of The Burning Archive has a great series about the peace process on the Ukraine. Why is it deadlocked, why they can't make peace.
This Australian (historian and ex-govt official) has a unique way of seeing things, some I disagree with but quite a lot to mull over.
Three main ideas which form a trap they can't get out:
1. Five State War (not 2 but 5 participants)
2. Divided Executives (cliques and individual thoughts within all the participants)
3. War Termination Phase (everyone wants to reach peace on their own terms)

I think it starts with this:
