I don’t think that north Korea has the power to do very much as far as terrorism in the united states all they can do is threaten . I think that sonny and the theaters are using threat of violence as a pretext to stop the movies.....all that North Korea need for the hacking is a expensive computer and computing tools and a few good hackers
Doesn't take much to assassinate a few people. If they can hack Sony's back office database, they can locate people. NK managed to penetrate a closed society with no significant Korean community like Burma and almost take out the hardest of the hard targets - the South Korean president. They "failed" in that they only took out several South Korean cabinet members. Think of how McVeigh and Nichols managed to destroy the Murrah Federal Building. NK's operatives don't need to go after anything so heavily-protected. By comparison, Hollywood personalities are practically naked.
