Who lost in Crimea? If there is a country to be added to Ukraine, it's Turkey.
The referendum decision of Crimea to return to the Russian fold, after Turkey lost it to the Russian Empire with the 1774 Treaty of Kucuk Kaynarcam, has spoiled Turkey’s strategic ambitions for the region. What kind of ambitions? Nothing to do with recovering Crimea geographically, but to bring back to life cultural and historical heritage of the Crimean Tatar Khanate.
