article: The film told the story of a fictional plot to assassinate Kim Jong-un. Hackers broke into film company Sony's computers, and weeks later threatened to target any cinema which screened the film. An FBI investigation concluded that North Korea was to blame for the cyber attack. North Korea responded angrily, with Kim Jong-un calling President Obama a "monkey". What do we know about his ambitions? Four insiders offer their insight into what Kim Jong-un wants. Jean Lee was born in America to South Korean parents and grew up hearing stories about Korean families separated by the war in 1953. A few years ago, she became the first foreign journalist to open a bureau inside North Korea. She was in the crowd when Kim Jong-un was first introduced to the Korean people at a military parade, and says he has had to work hard to establish his own power base. "When he came out there was just a complete sense of shock and awe among the people at the plaza. They had never seen a picture of him. They had only really known of his existence, officially, a few weeks earlier. "It was quite a shock to see somebody so young who was being groomed to be the next leader. He was not the oldest son, so wasn't the obvious shoo-in. There's clearly something about him, ambition, perhaps a kind of ruthlessness, some qualities that his father saw in him that he thought would carry this country into the next generation." The world saw that ruthlessness a year ago, when he ordered the execution of his uncle for allegedly trying to overthrow the state. And the regime is known to use violence to quash dissent among ordinary people too. But Jean Lee says it would be a mistake to think Kim Jong-un maintains control only through fear: "One of the things that I've seen on the ground over the past couple of years is all the construction of these skating rinks. There's actually a skateboard park, the ski resort of course that opened last year, massive projects. I see all of this as an investment that they're making in their future. He is a young man. If he is going to win the support of the future generations of North Koreans who are going to be his power base, he's got to find a way to win their loyalty and this is part of that." Geoffrey See is a Singaporean who has been travelling back and forth to North Korea for the past seven years, working with young entrepreneurs. He says North Koreans are now thinking more innovatively about the economy: "About six years ago when we first started our programme, our counterparts would often start off with a very long spiel about socialism and how this is the system they have and they are never going to change it. "In recent years instead of saying that, people talk about... trying to bring in what's best from overseas, and try to adjust it to fit into the system. So I think that's a
