Because of advances in technology, Hitler always had an array of microphones and a PA system. Thus he was able to reach thousands upon thousands who would stop to hear what he had to say. As he rose to power his propagandist Joseph Goebbels was able to create a false reality surrounding the Third Reich and Hitler. During WWII America cornered the market on propaganda with its newsreels and Hollywood stars supporting the 'war effort.' Today we have the advent of the internet also the dark web and various methods of all but undetectable communications waging a Jihad war against Western culture. What's next?
How do go from the broad concept of propaganda to "various methods of all but undetectable communications ['by jihadists']" and imply there's an equivalency?
