The tactics employed by the progressive globalist machine were developed in the 30s and 40s by Nazi Germany and Stalinist Russia, perfected by Communist China in the 50s and 60s, and utilized extensively by American Liberals. Exposed in a fictional format by George Orwell's work of Fiction entitled 1984, it was scientifically first exposed by Robert Jay Lifton in Thought Reform and the Psychology of Totalism: A Study of 'Brainwashing' in China.
The term 'brainwashing' was first coined in the 1950's during the Korean War to describe tactics employed by the Communists. It tried to explain how this totalitarian regime was able to completely indoctrinate captured U.S. soldiers.

Behavioral modification, thought control, thought reform, brainwashing doesn't require advanced gadgetry, it doesn't necessarily have to employ incarceration and persistently drilling foreign concepts into your mind. Civilized people are already chained to the flock. The only thing brain washers need is to be able to bypass the rational thinking part of your brain and implant the suggestions and commands to Obey and comply. The Modern behavioral modification, brainwashing and propaganda campaigns of the Left does exactly that.
