Earlier quoted context omitted.
Crimea is a special case: it used to be Russian but was reassigned to the Ukraine at the time when they both were part of the USSR. It wasn't a big deal until the USSR dissolved and suddenly Crimean residents turned out to be in a foreign country.
It had been Turkish before it was Russian. Should we go on? Besides, the indigenous population (Crimean Tatars) and the Ukrainians in Crimea never thought of Ukraine as a foreign country.
Crimea was called Crimean Khanate at that time and the backbone of its economy was the slave trade. As a major slave trade hub it has seen many hundreds of thousands of Russians and Ukrainians captured by Crimean Tatars and sold to Turkey until Catherine the Great's counter-terrorist operation finally put an end to it in 1783 :)
This dramatic history rooted in inability of the Crimean Khanate peacefully coexist with Russia can hardly be compared with a single action of a Soviet bureaucrat in Moscow in 1954.
And you are misinformed, Crimeans Tatars are not the indigenous population, they are a remnant of the Golden Horde.
