Hilarious Khandro.
The history itself is, as mikey says, irrelevant, given the criminal nature of the annexation, which involved taking the parliament hostage, and then flouting international law by invading part of a sovereign nation while claiming to be nothing of the sort, then organising an illegal "referendum" held in an atmosphere of fear and intimidation.
Crimea, in fact, if we're talking "Russia" was only ever really Russian from the time of the Crimean war until 1917, and for 9 years from 1945-54. From 1921-45 it was a Soviet republic. So, that makes 73 years part of Russia, and 60 (1954-2014 if you accept Russian rules) Ukraine. So the claim that Krushchev's was an arbitrary one that flew in the face of history is false. Previously it belonged to the Tatars for 400 years. In fact, one can't help noticing the words "annexed by Russia) creeping up twice there. Who says history doesn't repeat itself :-)
