After securing his position in a bloody confrontation with the Iron Guard, Antonescu involved Romania in the war against the Soviet Union. Antisemitic measures and the clampdown on dissident activities reached a peak. Ailing from heart disease and noticeably poor, Moscovici was threatened with imminent eviction from his Bucharest home in Vatra Luminoasă, and had to move in with friends. As noted by his daughter Mira, the signal for this persecution was an article in the fascist newspaper "Porunca Vremii". Against the family's protests, the house was listed for rent by the Romanianization bureau, which had barred Jews from placing bids. When Moscovici presented his certificate of service in World War I, guaranteeing him special treatment, the officials objected that he was not a war invalid. Moscovici was also prevented from cashing into his Journalists' Union pension, owing to his racial origins. He was advised to seek an interview with Antonescu, but he rejected the idea outright. Although exposed to such persecution, Moscovici had remained cautious of the Soviet Union, and informed himself about its crimes. His young friend Belu Zilber, at the time involved with the clandestine PCdR, recalls a brush with the anticommunist Moscovici some time after the Battle of Stalingrad. According to Zilber, Moscovici shouted at him that: "those Katyn people are coming, and they're going to kill you!". In summer 1943, with Petrescu, Moscovici also wrote a note to the International Revolutionary Marxist Centre, detailing the "treason" of Flueraș and Grigorovici.
