 Choosing to remain in exile to Italy after the Soviet occupation of Romania, Petrescu-Comnen spoke out against communization and lectured in particular against the Danubian Confederation project; nevertheless, he intervened to mitigate the effects of drought and famine in his native country.By 1947, he was also collecting and publishing in Florence his records of the war, and of his own part in it, as "Preludi del grande dramma" ("Preludes of the Great Tragedy"), followed in 1949 by the more detailed "I Responsabili" ("The Culprits"), at Mondadori.In exile, he resumed contacts with Carol, who stated his appreciation for the diplomat and described "Preludi" as the best analysis of Romania's plight in the late interwar.
