As to the motive behind it, McGoldrick questions the claim it was intended to silence Vatican Radio. The radio station's transmissions to the enemy and anti-Nazi broadcasts already ceased in May 1941 when Mussolini, under pressure from Hitler, threatened to invade the Vatican and close it down.[21] But from September 8, 1943, when Germany invaded and occupied Rome, both British and American media outlets unleashed a series of totally untrue (“False News”) reports that the Nazis had invaded the Vatican, imprisoned the Pope and arrested a number of Cardinals. This inflamed Catholic opinion in Latin America but especially in Argentina, the last South American country to maintain diplomatic relations with Nazi Germany.
