Even from Italy , Petrescu-Comnen closely observed the Great Depression and the decline of the Weimar Republic . Already in 1931 , while vacationing in Brittany , he had predicted that Germany would fall to communism . His return to Berlin was facilitated by Carol II , who complained that the outgoing ambassador , Gheorghe Tașcă , was " nonexistent " . The establishment of a Nazi regime came as a surprise . Petrescu-Comnen was prudent in his contacts with the Nazis , and his diplomatic notes of the time were ambivalent . Former Prime Minister Iorga , who remained friends with Comnen , records that Comnen thought Adolf Hitler " naive and sincere , still learning the ropes . " During 1934 , Comnen was hoping to drive a wedge between German re-armament and Hungarian irredentism , approaching various factions represented in the Hitler Cabinet . In May , he invited Ioan Lupaș of the Romanian Anti-Revisionist League to lecture in Berlin about minority religions in Romania . Later that year , he and consul Constantin Karadja obtained from Hermann Göring a guarantee that Germany would not go to war over Hungary — but this pledge was quickly dismissed by Konstantin von Neurath and Alfred Rosenberg . Rosenberg was persuaded that Comnen , a " Titulescu representative " , was lying , and began maneuvering to have him recalled . Comnen 's Russian policy was soon restored by the apparent upset in German – Soviet relations and the Franco-Soviet Treaty of Mutual Assistance . He preferred this realignment to the Nazi alternative : his notes of 1936 show him alarmed by the " antisemitic objective " of Nazism ( accurately predicting a '' Kristallnacht '' ) , by the regime 's public anti-Catholicism , and overall by the " nebulous criteria of German law "
