Well, the brain washing works superbly in North Korea...it blows away to see all those pitiful puppets crying and chanting love for the Kims and hate for the USA.
We should encourage our students to do reports on North Korea. What a shock it would be to the kids in the classroom to know that there is such a hell hole on planet earth. Teachers should teach about North Korea and other despotic regimes, current news would be a great way to introduce conditions in North Korea. American kids need to get out of the TMZ zone and learn more about the DMZ.
I think it's fear of being sent to a gulag, as much as brainwashing.
