Lost in Europe

In a New York Times arts section review by Jason Farago of "Chagall, Lissitzky, Malevich: The Russian Avant-Garde in Vitebsk, 1918-1922," a new exhibit at the Jewish Museum in New York, comes a reference to "Belarus, the last dictatorship in Europe." What about Russia? Turkey? Crimea? I suppose Russia and Turkey both are partly in Europe, partly in Asia, but they aren't free countries, at least according to Freedom House, and they are partly in Europe. At least using a geographic definition of Europe.
