Peter was deposed by Yugoslavia's Communist Constituent Assembly on 29 November 1945 with Yugoslavia proclaimed a republic. After that, he settled in the United States. In 1948, Peter visited Chicago, staying at the Drake hotel, visited the Inland Steel works and Armour stockyards "where many Yugoslavs work" and spent much time at the Serbian Orthodox Seminary of St. Sava. As a king without a throne, Peter was something of a novelty for Americans, and addressed various civic groups in the Midwest, for example in 1949 it was reported that the “young, modern, democratic monarch who refused to accept the situation in his country” spoke to the Kohler Woman's club in Sheboygan on the subject of "My kingdom for freedom". In 1951, Peter went on the "Ford Festival" TV show, where he was described as a "sad-eyed youth" who was "a flop as a TV personality" as he was noticeably nervous in front of the TV cameras and was quickly dismissed by the host, James Melton. Right up until his death, Peter continued to nurture hopes that one day he would be restored to the Yugoslav throne, in the words of the American journalist Peter Hockenos being a "forlorn figure" while "rival emigre groups drew the hapless king into their incessant schemings and quarrels. The royalist community resembled a bad caricature of a powerless, squabbling diaspora". A romantic, impractical man, Peter held to a completely unrealistic hope that there were still bands of Chetniks active in the rural areas of central Serbia who would rise up at the right moment when Peter led an army of emigres in an invasion of Yugoslavia, and together they would overthrow Marshal Tito.
