actually, no I wouldn't, because when a Westerner goes to NK, he or she is strictly controlled as to what they can see. In particular, no citizen will talk unguardedly to you because of their intense fear of the police.
If you think that's not true, why don't you tell us about your trip there (you did take one, didn't you?)
You still haven't told us whether you've been there or not.
As for the Western picture of it: it comes largely from NK citizens who've escaped. Call it "propaganda" if you like, but if it were false then there would be a net inflow of people who are as hip to reality as you think you are. Is there?
South Koreans would be trying to move IN if you were correct; after all, they're closer than anyone and they speak the language.
Just answer us this: is an NK citizen free to emigrate to some other country?
