Rousset's post-war activism focused on defending human rights and exposing totalitarian abuses, especially in the Soviet Union. In 1949, he famously challenged former prisoners to join him in investigating Soviet labor camps, arguing that such systems were not exclusive to Nazi Germany. His efforts to expose the atrocities committed by Stalinist regimes were influential, helping to shape post-war intellectual debates about totalitarianism. | Rousset's post-war activism focused on defending human rights and exposing totalitarian abuses, especially in the Soviet Union.
