"Perception management" - also known as "public diplomacy" or "military support to public diplomacy" - is a propaganda strategy for controlling how a target population views political events. Refined by intelligence services as they tried to manipulate foreign populations, the practice eventually seeped into domestic U.S. politics as a way to manipulate post Vietnam War era public opinion. "If want a picture of the future, imagine a boot stamping on a human face…FOREVER!"
- George Orwell
