You mean the same tactics of "re-education" used before all over the world? Take a look at the catholic church and the indoctrination of the native tribes of Central and South America. That is a mere tip of the iceberg.
Re-education has been going on long before the Korean war and hasn't been the exclusive domain of the Yellow Heathens of Asia. I do remember something about our own American government shipping young Indian children off to boarding schools to make them better Americans.
And don't forget eugenics in America, I remember seeing a documentary about a program (pre-nazi) in America that warehoused morons(no bullshit, they were serious about this term) with the goal of removing their "bad" genes from the American gene pool.
I wish I could remember the name of that documentary, but any way many people look at the specific and systematic thought reform, or brainwashing, models as being started in the east(China, Korea) and extended by us.
