Sympathetic toward the revolutionary fascist Iron Guard, of which her son Alecu was also an affiliate, Cantacuzino switched her support toward Ion Antonescu's government in early 1941. Having earlier reported to the League of Nations on the damages caused by the Spanish Civil War, she was also critical of Antonescu over the 1941 Odessa massacre. This was her last known public cause. Cantacuzino died, in relative obscurity, not long after Antonescu's downfall.
