In this excerpt from a documentary, there is a fascinating demonstration of the role of Edward Louis Bernays (here) in creating the American political public response and use of the Cold War.  Bernays is considered the father of Public Relations.  The case example of Guatamala is very chilling and interesting . . .

Now, compare that to some of the very same strategies in use today for very much the same purpose and in very much the same way . . . just even more effectively.

All the best,
