I always thought North Korea only had dial up - how do they intend to hack anything with that?
In this day and age, it's reasonably easy to block a countries IP, preventing access, and as North Korea only has about 4 IP addresses, then the job is even easier.
I'd suggest, the threats are from outside of the country, meaning there are 'spies' all over the world for North Korea.
Or more likely, this isn't the case at all, and an organisation fighting for truth and justice has taken up the chalice.
Either way, Sony won't have taken the decision lightly, as they are undoubtedly loosing a small fortune from pulling the plug.
I'm in two minds. The first is down the line of restricting freedom of press, freedom of speech, freedom of thought and opinion, the other is that there is much hype and propaganda about anything that is different. This one sided, unbalanced view skews the average thought process, and this, when repeated time and time again, can cause people to think in a certain way, towing a party line.
Of course, this film is a comedy, and I would have loved to have seen it on that merit, but, the knowledge that people will form an opinion by artistic representation scares me.
There are those who think of Kazakhstan to be filled with Borats. Russia to be filled with people who drive like lunatics, shooting each other (Not far from the truth in Moscow). Ukraine to be the badlands, Iraq, Iran, Afghanistan, Syria, Pakistan to be filled with suicide bombers and madmen with machetes, and they also believe Africa is a country.
All the above is most inaccurate - but for many, their opinion, formed by naivety is shaped by media in one way or another.
So, to summarise, release the film, and then fly to Pyongyang for a weekend break.
There is more to the picture with Sony than we have seen methinks.
(I'll admit, I am sounding a bit one world order etc)
