Your logic skills are lacking. Redrawing a boundary on the edict of a Communist dictator, Khrushchev, did not make Crimea “Ukrainian” any more than my prior 3 examples would make Staten Island Jerseyan, Hudson County “New Yorkian” or the UP Wisconsinite. As a separate nation not under control of Moscow, it only remained there for 23 short years (unlike the Texas/Mexico example, for which the former has been separated for 187 years). The entire map of the former Soviet states should’ve been redrawn in 1991 to take into account ethnic divides and boundaries based on actual history rather than bolting for the sake of doing so (though it was understood why they did - fine for the short term, but not for the long term).
Think before you post.
But for a brief period, Crimea was Ukrainian.
