Still incomparable:
a) Kosovo doesn't share a border with the United States
b) Crimea had an ethnic cleansing attempt by the Russians - you can't argue that Kosovo had all sorts of Americans move to Kosovo to make a majority American population so they can vote to be annexed by America....
c) Kosovo is recognized by 108 UN member states. Crimea ... I think only by Russia so far.
d) Kosovo, another "autonomous region" was part of a country that was falling apart. Funny how Milosevic revoked Kosovo's autonomous status triggering the breakup of Yugoslavia to further his "Greater Serbia" agenda.
e) If you want to compare Puerto Rico, I guess lets go back to the 19th century and compare things:
The Imperial census of Crimea in 1897 found that the population of the governorate consisted of 1,447,790, with 762,804 male and 684,986 female.
Language Number Percentage (%)
Ukrainian (Little Russian) 611,121 42.21
Russian (Great Russian) 404,463 27.94
Belarusian (White Russian) 9,726 0.67
By this standard Crimea belongs to Ukraine.
It is grossly undemocratic and unethical to hold a referendum in Crimea when:
1) the Parliament of the so called "autonomous region of Crimea" was raided by Russian paramilitaries
2) the federal government which the "autonomous region of Crimea" lies within: Ukraine, is under civil strife and is holding elections in a few months.
3) Russia itself conducts massive military exercises near the border, in addition to holding a port they lease from the Ukrainian government while having their own forces step off the base and surround Ukrainian military bases.
For the above reasons no one at the UN should recognize Russia's annexation of Crimea, and no referendum result should be observed until Ukrainian federal elections are held under international supervision until international observers agree on the election result. All of this is bullshit otherwise.
"Russian self defence forces" - what a fucking joke.
