In 1954, just after Stalin's death, Sartre visited the Soviet Union, which he stated he found a "complete freedom of criticism" while condemning the United States for sinking into "prefascism". Sartre wrote about those Soviet writers expelled from the Soviet Writers' Union "still had the opportunity of rehabilitating themselves by writing better books". Sartre's comments on Hungarian revolution of 1956 are quite representative to his frequently contradictory and changing views. On one hand, Sartre saw in Hungary a true reunification between intellectuals and workers only to criticize it for "losing socialist base". He condemned the Soviet invasion of Hungary in November 1956.
