>> Tatars are really the oldest owner of Crimea and they do not support Russia...
Tatars are not the oldest owner of Crimea. 2500 years ago Crimea was a Greek colony, then it was part of a Persian Empire, then Roman Empire, then Byzantine Empire [1] Mongols conquered Crimea only in 13th century.
Oldest that are living in that territory. No people from Persian Empire, then Roman Empire, then Byzantine Empire and Mongols at the moment living in Crimea.
