Didn't citizens of Crimea vote to return to Russia overwhelmingly (as it was always part of Russia). Who gave Crimea to Ukraine as a gift in what year?

Learn international law on the inviolability of state borders!
And if it does not suit you, then it is necessary to give the Crimea to the Turkey in general.
Or even Mongolia.
I am for civilization, not for rolling back in the era of imperial dictators.
We do not understand each other. Let's finish!
