Upon the outbreak of World War I, Vorel became an enthusiastic supporter of his adoptive Germany and of the Central Powers in general. In his private correspondence, he argued that Germans were "called upon to rule over the world", being especially impressed by Germany's submarine tactics. Vorel commented that peaceful civilization was illusory, and that hatred was the "fundamental habitus of living creatures". He also equated a German victory with the onset of modernization, leading to a "massive output of creative energy". While Romania still kept neutral, Vorel derided its pro-Allied agitators, including Octavian Goga and Ioan Toplicescu, endorsing instead the pro-German Petre P. Carp. As he noted in June 1915, Carp's newspaper "Moldova" was the only thing worth reading.
