The method or tool used in wartime propaganda?

Another Word for it is stimulation. The propagandist tries to stimulate others to accept without challenge his own assertions, or to act as he wants them to do. The idea of using suggestion or stimulation as a Propaganda device is that it will lead a public to accept a proposition even though there are not logical grounds for accepting it. The propagandist usually tries to side-step critical reactions from his audience, and therefore suggestion is one of his most important tools.
