Considering the zero credibility of even the idea of NK terrorists doing *anything* stateside, I really think this might be just very elaborate hype. NK did basically nothing over Team America: World Police with its portrayal of KJI, so why are "they" getting their panties twisted now?
The RONKs did not have the computer equipment back then but a few years later the UN illegally gave them several computers that helped them. Want to guess where the computers came from?
