A recent article pointed out that Crimea should return to Turkey if it declared independence.
What were the circumstances surrounding this agreement?
If Turkey were to make a claim on Crimea today, why would it be/not be a legitimate claim?
If Crimea declared independence during the time of Catherine the Great, how did the Ottaman Empire plan to enforce the relevant portions of this agreement?
