As Ukraine prepares to launch its spring offensive to break the stalemate against the Russian invaders, it's unclear if Ukrainian forces will be able to reach Crimea, the Black Sea peninsula which for centuries has been of vital strategic importance. In this episode, the Quincy Institute's Anatol Lieven, who spent three weeks in Ukraine reporting on public opinion toward the war, talks about Crimea's historical relevance to today's conflict. First taken by the Tsarist Empire in the late-18th century, the Soviets transferred Crimea to the Ukraine S.S.R. in 1954. More than a half century later, the Kremlin seized it back in the aftermath of the 2014 revolution that ousted a pro-Russia president from Kyiv.
