Lampoons north koreas leader, kim jongun. The studio says it is looking for other options for releasing it. As for who is behind the threats and Cyber Attacks on sony, the u. S. Is naming names. Chief u. S. Security correspondent jim sciutto has that. Reporter the blame has been doubt. The u. S. Is naming the rogue country in a sony hack. The fbi said, quote, the destructive nature of this attack coupled with its coercive nature sets it apart. We cannot have a society in which some dictator someplace can start imposing censorship here in the United States. Reporter the hackers sent investigators on a worldwide chase routing the attack through servers ranging from countries in asia, including china, then europe and latin america. Some servers in the u. S. Were even used. Still, the nsa and fbi were able to track the attack back to north korea and its government. Think of this as dirty tricks on a global scale. This has exceeded our expectations. They always make threats. Most people shrug off the threats so threatening a cyber 9 11, the film is dead. They must be incredibly happy in pyongyang. Reporter now that the country behind those damaging keystrokes has been identified, the administration is looking at how to respond. They caused a lot of damage, and we will respond. We will respond proportionally and well respond in a place and time and manner that we choose. Reporter the u. S. Could impose sanctions on north koreas prized military complex and further economic sanctions including implying even tighter restrictions to pyongyangs dollar denominated trade, desperately poor countrys life line to fuel food and crucially weapons. Theyre not yet calling the hack an act of terror or war. The cyber domain remains challenging. It remains very fluid. Part of the reason why its such a challenging domain for us is because there arent internationally accepted norms and protocols. Reporter there are other steps the u. S. Could take, stealthier reforms of retaliation, such as Cyber Attacks on Critical Systems in north korea delivered in a way that the source remains unclear. The stuks net virus that was used against iran. The administration very conscious of avoiding escalation. They dont want to provoke further provocation or even worse. Jim sciutto, cnn, washington. The ceo of Sony Pictures entertainment is defending his companys decision to pull the film from theaters. Michael linton spoke with Fareed Zakaria in this exclusive tv interview. The president says sony made a mistake in pulling the film. Did you make a mistake . No, i think actually the unfortunate part is in this instance the president , the press and the public are mistaken as to what actually happened. We do not own movie theaters. We cannot determine whether or not a movie will be played in movie theaters. So, to sort of rehearse for a moment the sequence of events, we experienced the worst cyber attack in American History and persevered for 3 1 2 weeks under enormous stress and enormous difficulty and all with the effort of trying to keep our business up and running and get this movie out into the public. When it came to the crucial moment when a threat came out from what was called the gop at the time threatening audiences who would go to the movie theaters, the movie theaters came to us one by one over the course of a very short period of time, we were completely surprised by it, and announced that they would not carry the movie. At that point in time we had no alternative but to not proceed with the thee at trick release on the 25th of december. Thats all we did. So you have not caved in your view . We have not caved. We have not given in. We have persevered and we have not backed down. We have we have always had every desire to have the American Public see this movie. Why not release it online in some form or the other, video on demand . There are a number of options open to us, and we have considered those and are considering them. As it stands right now, while there have been a number of suggestions that we go out there and deliver this movie digitally or through vod, there has not been one major vod, video on demand distributor, one major ecommerce site that has stepped forward and said they are willing to distribute this movie for us. Again, we dont have that direct interface with the American Public so we need to go through an intermediary to do that. Mitt romney says why not just put it on youtube and let the whole world see it. Thats certainly an option and thats certainly one thing that we will consider but, again, all of this has transpired so quickly that were trying to weigh the options as to how we can get this how to go forward with all of this. We were taken by surprise by the theaters, which is what we wanted to do first, and now were trying to proceed and figure out what the next steps should be. The president says he wishes i wish they had talked to me. What is your response . My response is that a few days ago i personally did reach out and speak to senior folks in the white house and talked to them about the situation and actually informed them that we needed help. The fbi has been with us now for several weeks and has been great, but i did reach out and explain the situation to them at that time. So the president is wrong when he says that you did not reach out to him . Well, i dont when hes asking about reaching out i wish they had talked to me first is the right. So we definitely spoke to Senior Advisors or a Senior Advisor in the white house to talk about the situation. The fact is, did we talk to the president himself and talk to him about what was transpiring as the theaters started pulling back and not and being unwilling to distribute the movie . No, but the white house was certainly aware of the situation. Not only did the theaters all pull out but you couldnt get any of the major Hollywood Studios to support you . George clooney writes that he put out a petition and tried to get support. He couldnt get a Single Person to sign it. Have you been surprised at the fact that nobody has been willing to rally around you . I am surprised, frankly. I mean, i understand on the one hand that my fellow studios and everybody else has their own commercial concerns and they, themselves, were worried about becoming the target, and it did make for a make this entire enterprise to be a very, very lonely affair, but on the other hand, it you know, this is a moment where you would expect the industry to rally around and support you. Is it your estimation that the theater owners panicked because the North Koreans do not appear to have the capacity to launch some kind of major simultaneous or really any significant terrorist attack in the United States. Why do you think they panicked . Well, what i can only imagine is Homeland Security came out that day and said that there was not a viable threat, and my sense of it, having had the conversations, was there was enormous pressure put on them by the malls, by the shops in the malls, by the surrounding neighborhoods who were also threatened in those emails to say that they shouldnt show the picture and they basically on the basis of looking at that, they decided that they wouldnt take the picture. Does that mean that a dvd release also becomes difficult because you would face the same challenge, which is the walmarts and the costcos of the world would have to agree to stock the dvd . Again, we dont have a direct interface with the American Public so we would require either throughon line or in a retail situation, we would need distribution. Yes, its fair to say if we cant find one of those large retailers or many of those large retailers to sell our dvds, we wouldnt be able to provide them with the interview. Is it fair to say, michael, that your hope and expectation is that the movie will be seen by people . We have always wanted the American Public to see this movie. We have worked tirelessly to do so, so absolutely. We would thats thats thats been the primary objective throughout. Michael, let me ask you to go through the sequence of what happened. When did you first realize that you had a problem . The first time we understood that there was an issue with the North Koreans was back in june of last summer when they came forward with various emails, statements and actually i think they were in touch with the white house itself and described their disfavor with the movie. At that time we reached out with experts at various think tanks within the state department to try to get a proper understanding of whether or not there was a problem here and whether or not we were providing a security risk, and we were told that there wasnt a problem here and so we continued to proceed. Including the u. S. Government told you there wasnt a problem . The u. S. Government told us there wasnt a problem, correct. So when people asked, the North Koreans threatened you, why didnt you take it seriously . We did take it seriously. We went to the people we thought were most expert in the area, people in the u. S. Government, people in various think tanks and inquired as to whether or not this would be a problem and they told us it wasnt. That actually is for the world to see as my stolen emails have been presented in public. There was an email between you and somebody at the Rand Corporation and and somebody at the state department, correct. Interesting interview from michael linton. We will hear more from him in our next hour including his response to criticism that the movie is in poor taste and never should have been made in the first place.

Pakistani forces say they killed several taliban insurgents today including a key commander in clashes in and around the city of peshawar. This comes days after taliban militants massacred 148 people at the school, most of them children. Earlier on friday the military also said it killed dozens of insurgents but didnt specify if they were taliban members. In peshawar schools have now reopened for the First Time Since this weeks massacre. Reporter it was no ordinary school run. This spoke volumes that most of the children arriving were brought by car to the school gate, not by foot, and were ushered in by armed guards. Reporter the Morning Assembly was somber but also defiant. How do you feel being back at school . I feel really scary after that thing that happened. It had made our hearts a little bit scared. I feel a little bit squared because if we are the next target. Reporter but do you still want to come to school . Yeah, for education. Reporter the First School Day since the Taliban Attack is a step towards a sense of normality for children in pakistan, but it is only the first hesitant step in what promises to be a long journey. Its not just the murder of 132 School Children in the Army Public School thats led to such widespread revulsion in pakistan, its the fact that children receiving a modern education are now a part of the conflict in this country. The professor taught at the school which was attacked where one of her sons was also a pupil. Surrounded by her family, she tells a story of how she had to identify her murdered colleagues and then found out what had happened to her son. They asked me to come towards the children and identify the staff and some of them i came out of there. They brought a boy towards me. They didnt know the situation. I lost my boy, too. I lost my son, too, and i was searching for him. Reporter another family devastated in a country seeking a way out of a war affecting teachers, mothers, and School Children. Just horrific what those families are going through and these sweet children going back to school even though they are scared. Well, a new warning tonight for americans traveling over the holidays. The state department issued an alert saying their threat analysis is, quote, strongly suggesting a focus by terrorist not only on targeting of u. S. Government facilities but also on hotels, shopping areas, places of worship, schools among other targets during this holiday period. That is from the state department. This morning two americans traveling overseas comes in the wake of this weeks deadly attack in sydney, australia. Two people were killed in that attack and the shooter also killed. We learned now that the cafe may not have been the intended target. We spoke with chris reason from seven network. Here he is. Reporter one extraordinary thing is that the news breaking today from journalists who dug into the gunmans background is that he was, in fact, targeting this building, this office, the channel 7 studios which as you know just 30, 40 meters across the plaza here behind me from the cafe, but he tried to get into this building, he was targeting a Breakfast Program called sunrise, he had a particular grievance with them and a Current Affairs program that we have called today tonight that had been doing stories with him over the recent years. He wanted to access the presenters of the show. To do what . We couldnt guess. When he approached the front door apparently assuming the security was too great, weve ramped it up since the threats, about this place becoming a target back in september. He chose a fallback target, the cafe behind me. Channel 7 staff extremely nervous about that. News that we certainly didnt want to hear, but the word is this was the target. The gunman originally from iran had a very troubled past and was well known to australian police. A separate attack elsewhere in australia ended in the deaths of eight children this week. It happened in a suburban home in karins, australia. A woman found stabbed at the scene has now been arrested. The children who died range in age from 2 to 14 years old. The woman is the mother of seven of them. Police have spoken with the fathers of the children but so far no charges in this case have been filed.

Well, throughout this past week we have heard mixed reaction to president obamas historic announcement of changes to u. S. cuba relations. Florida center marco rubio slammed the president s order just moments after the announcement but in havana it has mostly been a time of celebration. Cnns rosa flores is there. Reporter the narrow streets of havana are filled with sites, sounds and voices. Its those perspectives that make up the real cuba. Its people. Right now, everyone is talking about one thing, cuban relations with the u. S. How did you celebrate the news . How did we celebrate . We take some beer. We are very happy. We phone friends. Reporter in havana when you want to know the mood on the street, one of the places you can start is here, in central park. Theres always a lively conversation. Its known as the hot corner. Im asking so who thinks its a good idea for the u. S. And cuba to establish relations . Those ideas in the past. Some of that buzz, some of that energy, its for a future with lax travel and trade restrictions to make it easy for americans to walk into privately owned shops like these and buy art with classic cars, for example, maracas, mow men tows. Even though president obama said a visit to cuba was probably not in the cards, we asked people if theyd welcome the u. S. Leader would you like for president obama to visit . Yes. Why not . Reporter there are signs of a cuba frozen in time everywhere. The classic cars, the weathered buildings, but the recent news has people here optimistic about whats ahead for their children. Says its a Christmas Gift and he has kids and this is something great for his family. Like havanas old cobble streets, cubas relationship with the u. S. Is still a little bumpy and after all lifting the embargo still requires action from congress. But this move is just wide enough to give people hope. Rosa flores, cnn, havana.
