Lots of countries have changed borders throughout history including the ex Yugoslavia (through war), Czechoslovakia and the USSR itself in the past 30 years alone yes.
But the Crimea wasn't sold to the Ukraine or acquired in a war or ceded to Ukraine. It was simply gifted and to them by Stalin because both the Ukraine and Russia were part of the sane country, the USSR. Once the USSR broke up it made sense to take the Crimea back.
Almost all the people of the Ukraine were Russian. They wanted to be part of Russia like they had been for almost 200 years.
I am not going to lose any sleep over Crimea returning to Russia.
It's long past time for Russia and the US to deescalate and move on.
G7 should be G8 and they will be sooner or later.

That was Khrushchev, not Stalin, K was Stalin's boss in Ukraine, and wanted to get their support in his power struggle after Stalin's death.
