"Meanwhile, in the Crimea, people discuss an opportunity to separate from Ukraine and address Russia with a request to be accepted in the structure of the Russian Federation."
Whaaat? I mean, sure, Russia has been wanting Crimea for a long time for its access to the black sea, but even just the geography of the region would make that impossible without occupying Ukraine. Needless to say, if Russia occupies a foreign country using military force, the West would not be happy.
There are some US ships in Black Sea because of Sochi now. Let's wait until Sochi ends. Again Ukraine is interesting place. E.g. while some of them can be considered Russian because they don't speak Ukrainian language they consider themselves Ukrainians.
