The work focuses on losses stemming from the Soviet invasion in 1939 and subsequent occupation, the spokesperson said, adding that any political decision would come after detailed studies. Russia’s Foreign Ministry spokeswoman Maria Zakharova mocked the idea, saying Moscow could offer “a link to the video of the opera Ivan Susanin” as reparations. Historians interviewed by TVP World said claims framed as reparations would be difficult because the Soviet Union fought in the Allied coalition, and any lawsuit would more likely center on compensation. Experts said Warsaw does not expect payments but sees value in documenting Soviet-era crimes and raising international awareness.
