It continues to surprise me how many people don't seem to recognize the basic right of self-determination – ranging from the status of Ukraine to Scotland to Puerto Rico – from all sorts of different ideologies. e.g. non-Puerto Ricans argueing in favour of statehood well before it was clear the population actually wanted it (only since Nov 2020 is there a referendum with a small majority in favour of it).
That's up for Ukrainians to decide, not Russia.
