Maybe they know better than you. At the end, they live there. What you claim to know from North Korea and all that other countries from the "axis of evil" comes from TV.
Not what I claim to know but what I know. The difference between these two is that I don't claim to know what I know while not actually knowing it. The things I know about North Korea may be only part of the truth but there is no doubt about me knowing these things nor a necessity for me to claim knowledge I do not possess.
> all that other countries from the "axis of evil"
Where does that come from? I did not say anything about any axis of evil.
> comes from TV
I do not even remember the last time I watched television but I know it is more that 24 years ago since I had one of those contraptions. Nope, I do not get my information from television and have not done so for a very, very long time. What I know about North Korea comes from a diverse mix of sources on the 'net, from books on the subject, from interviews with North Korean escapees and from the odd travel report from people who went there - yes, some people actually visit the place. Satellite imagery provides proof of the existence of camps where escapees said they were so I tend to believe their descriptions of live in that state more than the denials which are thrown their way.
How much did the inhabitants of the Soviet Union know about the conditions in GULAG? Those who went through the system and survived to return to society were not eager to tell the tale for fear of repercussions. It took the death of Stalin and Khrushchev's subsequent speech “On the Cult of Personality and its Consequences” at the last day of the party congress of 1956 for some of the information - but only some, and only until Brezhnev came into power - to be the subject of discussion among Soviet citizens.
> Maybe they know better than you.
Stalin was a monster but to many people in the Soviet Union he was like a god - just like the Kim dynasty in North Korea has a god-like status to many North Koreans. They don't know any better, yet. Let's hope they will get to know the truth, soon.
