In 1940 he was transferred to Washington, D.C. and, with the fall of Yugoslavia to the Germans in 1941 he began working in the press office in New York City.
From 1943 on, he worked with Louis Adamič, an American writer of Slovene origin, in the campaign against the Yugoslav government-in-exile in London and the recognition of Tito and his movement.
After his return to Belgrade he managed to obtain a visa to go abroad and around Christmas 1945 he travelled to Bari, from where he sent a telegram to his wife Nina: "Left Tito's paradise forever".
After returning to the U.S., in 1946 he wrote in New York his famous Reader's Digest article, Yugoslavia's Tragic Lesson to the World.
In it he enumerated all the reasons for his disappointment with Tito's Yugoslavia and urged Americans not to fall for false slogans.
