No, but I joined the Resistance

"Beckett was always politically aware. In Dublin in the 1930s, he associated (in spite of his impeccably Protestant and Unionist family background) with the members of the small leftist fringe of Irish republicanism—Charlie Gilmore, Peadar O’Donnell, and Ernie O’Malley. One of the more startling revelations from the splendid Cambridge edition of Beckett’s letters was his deeply serious attempt to move to Moscow in 1936 to study cinematography with Sergei Eisenstein. He did succeed in traveling to Hitler’s Germany, where he lived between September 1936 and April 1937, and his up-close study of Nazi propaganda is a strong influence on his later work. And of course, he chose to return from the safety of Dublin to Nazi-occupied Paris, where he became an important member of the underground cell Gloria SMH. In 1977 Richard Stern asked Beckett whether he had ever been political. The reply—“No, but I joined the Resistance”—is one of his typical self-canceling sentences, in which the second part utterly negates the first."

C'est cruel pour Sartre qui écrivait pour des journaux collaborationnistes quand Beckett se cachait chez Nathalie Sarraute, et qui a occupé au lycée Condorcet le poste d'un enseignant juif révoqué par Vichy.
