> Even Crimea itself is an example of stolen territory. It was part of Russia, until (Ukrainian) Khrushchev moved it under administration of Ukrainian SSR in 1954. It was excused as being in the same country anyway.

Not entirely true as it was not a single-handed decision, it has been voted by a council.

> When USSR dissolved, the Crimean referendum about returning it back to Russia was ignored by the newly-formed government in Kiev.

Could you precise which referendum are you referring to? There were only two of them if I remember correctly: 1. Referendum for independence of Ukraine: Crimea participated and voted "for". 2. Referendum to make Crimea an autonomous republic: was voted "for" and made Crimea and autonomous republic (as a part of Ukraine).
