Knowledge Issue Associated with North Korea

A Knowledge Issue could be something used for History, such as the limitations of knowing something. For example, if North Korea is concidered a Secret State, how can others know anything about them, and how can they know anything about anyone else?

As for TOK, however: To what extent is North Korea a “secret state”? would be an appropriate question. If they have a heavy security on what resources go in or out of their country, yet there are videos leaked and such propaganda, then perhaps their security is not as heavy as they thought!
