It may take two generations for the people of North Korea to recover from living in a solitary confinement psycho ward and learn that it is OK to think on their own.
But then I could be wrong. Look how fast Eastern Europe came around after decades of Communist rule. Then again, Eastern Europe was not living under the degree of isolation that the people of North Korea have been.
Germans? Thinking on their own? When did this happen?
Eastern Europe still had:
Food
Education
Christianity
Have you ever seen pics of the NORK soldiers standing next to US or the SK? They look like grade school kids next to College kids. Decades of starvation has taken its toll. Long time to recover. Generations.
