The Open Republic was among the signatories of an open letter against the Russian prosecutors’ decision to disband the international association “Memorial”. The letter, calling “Memorial” a global treasure, emphasizes its fundamental role in uncovering the truth about the mass murder of Polish officers in Katyn during the Second World War and other mass communist repressions. The letter also calls the “Memorial”, the conscience of contemporary Russia, and describes attempts to disband it as an act of political aggression.
