> That’s misleading framing.
Your original claim was that the independence referendum results suggested Crimea wanted to stay in Ukraine and not Russia. I agree, that framing was misleading as they were never asked that question.
> Now, those are obviously not strong results, but it also doesn’t immediately suggest the handover was a mistake. The split is even.
You are listing the Yes and No percentages while ignoring the low turnout. Only 37% of the electorate of Crimea and 36% of Sevestopol voted yes. The next lowest Yes vote was 64%, a clean majority.
> It would not have been sensible to ask “would you like to join russia” as Ukraine was already part of the USSR at the time the question was asked.
Ukraine was part of USSR, not Russia. I don't see why it would not have been sensible to ask Crimea if they wanted to join Russia. If Ukraine has the right to self determination, why doesn't Crimea?
> My point was, to come to the framing that this was “Kruschev’s mistake” one needs some preconceived ideas about how things ought to be.
After witnessing recent events, one could also look up the history of the region and conclude that Krushchev made a mistake.
Everybody has a bias. But you are pretending your particular framing is neutral.
