Sounds promising in the short term any way. But I don't think Russia will stop until they have a land connection to Crimea. |It's just going to take them longer than they hoped originally.
I hate to say it, but it is almost time that Ukraine surrenders and starts negotiating terms, because Russia will get it eventually anyway and no one will stop them.
- Cede the territory in exchange for debt forgiveness,
- compensation to Ukrainians that wish to relocate and don't want Russian citizenship,
- a permanent and enforceable peace treaty, and
- the acknowledgement for Ukraine to join NATO/EU without Russian interference.
Eventually they are going to lose the territory and won't get anything for it, or it will be susceptible to rebel extortions forever.
