One of the ways in which Wilsonianism permeated Europe during the Great War was through the activities of the Committee on Public Information (CPI). Historians are still discussing the effectiveness of the CPI's propaganda abroad. This article contributes to this debate by focusing on and problematising the case of Italy. The Italian scenario confronted the CPI with a series of challenges that exposed the limits of America's germinal public diplomacy. The author's argument is that, in spite of its numerous attempts, the CPI's activities in Italy resulted in a substantial failure, which was mostly due to an inter-institutional conflict of interests and competences between the CPI and the US embassy in Rome. Such a short-circuit prevented US propagandists from developing a genuine understanding of the Italian public's preferences and resulted in what people in the Peninsula perceived as a general lack of empathy.
