Do I get this text from the book right when it sounds to me that the enemy produces fake documents for a group which they want to subvert?
"The term "black propaganda" is reserved for those materials "planted by the United States but in such as way that it seems to be the product or even an internal document of the target group." In other words, "black propaganda" is nothing less than a form of intellectual and political subversion."
What stops the enemy then from producing fake documents for the use of framing and convicting for punishment an individual or a group of people? When governments do their own PSYOP or PSYWAR operations on their own citizens, then those governments also are the enemy.
