““The assumptions that propagandists are rational, in the sense that they follow their own propaganda theories in their choice of communications, and that the meanings of propagandists' communications may differ for different people reoriented the FCC* analysts from a concept of "content as shared" (Berelson would later say "manifest") to conditions that could explain the motivations of particular communicators and the interests they might serve. The notion of "preparatory propaganda" became an especially useful key for the analysts in their effort to infer the intents of broadcasts with political content. In order to ensure popular support for planned military actions, the Axis leaders had to inform; emotionally arouse, and otherwise prepare their countrymen and women to accept those actions; the FCC analysts discovered that they could learn a great deal about the enemy's intended actions by recognizing such preparatory efforts in the domestic press and broadcasts. They were able to predict several major military and political campaigns and to assess Nazi elites' perceptions of their situation, political changes within the Nazi governing group, and shifts in relations among Axis countries. Among the more outstanding predictions that British analysts were able to make was the date of deployment of German V weapons against Great Britain. The analysts monitored the speeches delivered by Nazi propagandist Joseph Goebbels and inferred from the content of those speeches what had interfered with the weapons' production and when. They then used this information to predict the launch date of the weapons, and their prediction was accurate within a few weeks. *FCC - Federal Communications Commission””
