AnitaPeterson, my upset tone in the reply did not direct to your post, but rather the video itself. If it bothered you, I apologize.
That said, I think you are doing completely wrong analogy here. Well, yes, US goverment sometimes can be very good at propaganda, especially war times (or when they think it is). But, that is no comparison, even remotely closed to what has been done and still going on on NK.
As you can see, for instance, this particular P&N forum is full of people who are very (or even extremely) critical to the goverment, who don't believe (sometimes at all) the goverment is saying, and who are willingly participate in any reformation of the goverment. Now, that is hardly a "brainwashed" country. If you label someone that has different idea than you or is willing to accept the goverment says as "brainwashed", then that is the end of arguement. Maybe, they just have seen enoguh information as you have, and decided to believe the government, just like you choose not to (I'm presuming here). Heck, if you really don't like your goverment, you can always participate in the vote and do your best to persuade others to do the same. Well, for worldwide propaganda, if US is so successful at brainwashing, isn't it odd that you can easily find anti-american sentiments in every bit of this world? Basically, what America (or its current government) is doing is "PR" or "advertisement", not brainwashing. You can choose not to believe it, as well as to believe. That's what every single parties and government in democratic societies are doing. Making themselves looking good, so that they can earn the next vote. It is up to YOU to believe it or not.
Quite contrary, in the 50+ years of NK's history, there has been only one party, one person (Kim Il-Sung) and his son (Jung-Il, and now they are talking about his grandson taking over the country again), and people are so completely misinformed and brainwashed, there has not been a single demonstration, a single voice of freedom, and a single opposition to the party or the god-like general (and his family). Well, technically there has been a few, but person who participates in such activities has been either shot in public, chopped his head, hung, sent to labor camps for life time, or just simply disappear. And of course his family would suffer the same fate. This is what is still going on in NK right now very this time, when I'm sitting in front of a monitor and writing this garbage on Anandtech P&N forum. In this country, the way of thinking, what you have to believe, what you have to love and hate are just "pre-determined". If you are an outsider, then you are just dead. Very simple.
Thank god, the country is now losing its grip on its borders and there are many refugees trying to escape to China and come to South Korea (or even US). But it seems, unfortunately, nobody really cares of them, except handful of people.
Please do not compare so called US propaganda with this one. It is not a matter of "degree".
