BERLIN: A human rights activist since the 1980s, Oleg Orlov believes Russia took a turn after the collapse of the Soviet Union and a democratically elected president. But Vladimir Putin came to power, crushed dissent and invaded Ukraine. Eventually, Orlov, 71, was imprisoned for opposing the war. Freed last week in the largest East-West prison swap since the Cold War, he was forced into exile — like the Soviet dissidents of his youth.
