And a dozen entities. Irans Foreign Minister responded, also on twitter, saying iran unmoved by threats as we derive security from our people. We will never initiate war, but we can only reply on our own means of defence. So how serious a moment is this . Im joined by our diplomatic editor. Is this a harbinger of much worse to come like a Handbrake Turn on iran policy . In a sense it is Unfinished Business from the last months of the obama administration, these missiles, over 1000 mile range, not very accurate, the general view of Intelligence Experts is that they are being tested as Nuclear Delivery systems, that is counter to United Nations agreements. Another problem is that some people connected with these, the firing of warships by rebels in recent months, another issue is that basically apart from one counterstrike against those batteries president obama kicked the can down the road. So emphasis tonight from us officials is that this doesnt mean the end of the nuclear agreement, it is a separate issue but we have to do something. The Trump Rhetoric is heavy but these are not, as you say, heavy duty sanctions. Well, heres the problem which is that President Trump and his National Security adviser mike flynn are very hard line on iran. So these aspects of sanctions about these two separate issues which you might see is Business As Usual for the National Security system in washington are coming at a time when President Trump has said all options are on the table now for iran, mike flynn has said they are on notice. The dangers of misperception, the iranians have said that they will carry on testing and President Trump feeling he has drawn a red line, remember how he criticised president obama for not enforcing the red line of assyria, he may feel he has to defend it, the scope for sliding into conflict now is considerable, i would say. The red line over syria. Thank you very much. Mohsen sazegara was the iranians deputy Prime Minister in his late 19805 but became disillusioned with the regime and is now a political activist based in washington, dc. What is your reaction to the imposition of these sanctions . These 25 persons and institutions, i expected it because of an escalation of tensions between these countries. It started from the white house three nights ago by flynn and trump, both of them. Do you sense the iranians pushing a little, nibbling away at donald trump with this test on sunday . Niggling. I think that right now, the top officials in iran, the leader, i mean, and the revolutionary guard, they are very cautious and they prefer not to escalate the tension, and more than that, i think, they are waiting for the results of the president s trip to moscow to see what President Putin can do for them, because they expect that President Putin can reduce the tensions between washington and iran. It is not necessarily to the advantage of tehran to have putin and trump close, is it . No, it is not to the benefit of one side, and to the other side, if there are new sanctions against putin and russia, if these are passed by the congress, it shows that putin cant solve his own problem. So both sides are not good signals for iran. Lets look separately at the sanctions and also the Visa Restrictions, two separate things. Your reaction to the Visa Restrictions . Visa restrictions definitely harms a big group of iranians who live in the usa and their families, relatives, travel, and helps the regime of iran for its own propaganda and mobilises people to support the regime. But the sanctions against the revolutionary guard, or the leader, and the institutions, most of them are corrupt in iran as well, i think this is Something Else that the people of iran may like. It is interesting what you say because there is a strong Entrepreneurial Community of american iranians who do not like what is happening with this visa. It looks as if President Trump is prepared to put up with that in order to pursue this heavy policy on visas. He doesnt actually care about the impact that will have on the attitudes of american iranians. By the way i am definitely against such type of restrictions for iranian citizens, or any sanction which harms all the people of iran. But i support the sanctions which are targeted and are smart against the top officials and the people who abuse and violate human rights. Is it your sense that President Trump is ad hoc orjust sounding like a hawk. Hawk, or just sounding like a hawk . Frankly speaking, i feel that sometimes he is unstable and i cannot rely on his stances, but the guys that he has picked for his administration, they are hawks. Especially with respect to iran, they are too tough. Mohsen sazegara, thank you forjoining us tonight. Thank you for having me. Does truth matter . Should we trust our leaders to tell the truth, and is there something materially different about truth in the technological age . Theres so much stuff out there. How do we gauge whats true, half true, or false . In the past month, new phrases have entered the political lexicon, in particular, fake news and alternative facts. But what if theres another, explosive ingredient in this febrile mix the ability, literally, to manipulate the words coming out of someones mouth . Heres our technology editor, david grossman. How do we know that something happened . That what we are seeing is real . That we are not being fooled by fakes . Some tv trickery is pretty familiar to us. This technology, green screen or colour separation overlay, has been around in some form for decades. It allows us to convincingly give real people backdrops of Virtual Worlds for them to interact with. However, we are about to cross the threshold into a new world where it is possible to convincingly recreate known real people famous people like politicians and have them say or do more or less anything. Were a few years, but not many years, away from a situation now where we can not only create a pretty sort of realistic environment for people, but we can also do things like manipulate their voices and manipulate their facial expressions and modulate their speech in real time. Here we demonstrate our method in a live setup. This is the face 2 face project, a collaboration between stanford university, the Max Planck Institute and the university of erlangen nuremberg. As we can see, we are able to generate a realistic and convincing re enactment result. They can take the facial expressions of one person and match them onto the features of another in real time. The results are already amazing and only going to get better and better. It seems like they are being developed out with a specific ethical framework that helped them to actually assess before technologies are developed, the actual implications of the technology in society. The perfect environments for fake news, for a widespread dissemination of fake news. Weve had faked photos for decades. This hugely damaging image ofjohn kerry supposedly sharing a stage with vietnam protester jane fonda was actually a composite of two images. Now the company that invented photoshop, adobe, has unveiled a new, potentially Game Changing manipulation tool. At this event in november, adobe demonstrated voco, which, loaded with 20 minutes of real sample voice, can then make someone say anything just by typing it in. And play back. I kissed jordan three times. Adobe said the auyo audio will be watermarked so that fakes are easy to spot but that may not stop them spreading. Altered audio. Often the things we see as fake news or false stories are actually very easily debunked in a matter of seconds. But it doesnt necessarily stop them from spreading, partly because i think the mechanisms now are so quick in terms of how virality is created online but also because people believe what they want to believe. But is there a flip side to this technology . If it makes the fake seem real, what does it do to our perception of the real . Will it allow those intent on deceiving us to dismiss cold, solid, hard Video Evidence as Mere Trickery . Can you state categorically. . You are fake news. It becomes a term that can be used by anyone who wants to call out something that they dont like, and spread doubt about whether or not its true. And when you have a high level of distrust in stories, and you have a high level of distrust in institutions, which we do at the moment, then a term like fake news becomes almost meaningless, because its deployed in so many ways which actually describe things that are perfectly legitimate and true. Weve grown more sophisticated in our ability to discern what and who is real. However, accelerating technological change means well need to quickly refine how we weigh the evidence of our senses. Doctor, im flying. Were joined now by claire wardle, Research Director at first draft news, which aims to improve the standard of online reporting and the philosopher, simon blackburn, who wrote truth a guide. Good evening to you both in london and new york. Simon, is truthjust about the most important thing . It is very important in our day to day lives, our sensors are adapted to telling us how the world around us is and if we dont know how the world around us is we will not behave well in it. Give an example of how senses are adapted. Im pretty good at knowing of the bus is bearing down on me and pretty good at not crossing the road if i can see one bearing down on me. I would be much worse in life if i could not see that was a bus bearing down on me so i need the truth about that kind of thing and that is true of all kinds of ways i behave in my environment. If i couldnt tell. I need to know whether the food i am looking at is poisonous, i need to be able to rely on various deliveries of sense, sound, and of course trust in things that people tell me. But it was ever thus. Is there a difference now, has technology changed things . Communication has exploded so we get communications from very different parts of the world, notjust from our neighbours, our parents. Big communications from Media Outlets, fake Media Outlets and so one. Sifting what we are told, whether it is trustworthy, becomes much harder. We cannot go behind the scenes. I cannot see what the truth is about what bush is saying if someone else shows me some bizarre things. In a way, you make it your mission not to be a single sister but to find a way in which we can engage the truth. Do you think the technology that has just been explained in that film will make a huge difference . People look at peoples bases and think they can trust their eyes, trust what they see, and it is false. Absolutely. In the same way that Photo Editing Software and video Editing Software is on a laptop, anyone in the world can create visuals. Because of technology they move at huge speed across the world. 0ur brains are adapted to trust visuals more. As Technology Becomes easier and cheaper that is why we have at this explosion of false information. I suppose the more people there are checking to find out it is false. How do you get at the truth . We are having lots of people talking about News Literacy projects and educating people to stop and check. Were looking at our phones and scrolling quickly. Although we might know to be critical, sometimes things that are too good to be true, it is very easy to click share. We do not stop and check when we should do. Politicians particularly through the centuries have all tried to manipulate the truth one way or another at different times. In a sense, is it not easy because you can sift through and make decisions yourself . Is it not easier to get information to the access . As human beings, we want information to make us feel better. We are in a polarised world. You sit in groups of people youd think are the same as you and you want information to make you feel better. It is easier to double check and google something that does not necessarily mean we are doing that. What will it do to us . I find it destabilising sometimes if i do not know what is true and what is false. It is difficult to predict. If technologies do proliferate in the way described and they become very popular and everyone is using them, i should have thought one possible reaction, my own reaction for example, would be in a sense to retreat. That is very bad for democracy. If i say i am not going to believe anything about President Trump, i do not believe anything about theresa may, that means i am retreating from my historic duties as a citizen, which is to inform myself about policy and what these people are offering. The advent of Global Communication could actually signal a retreat. It could indeed. It is a rational response to a world in which nothing is trustworthy. If you cannot trust anything, do not believe anything. Do not act. That basis for action, does that come from Early Education . Had you get a basis for action . 0ur senses tell us how the world is. We are very good at using them put up relying on other people, that is something you learn when they are trustworthy and when they are not. Unless you can get some experience in both sides of it, youre not going to be a fully performing, fully active adult. Does that fill you with dread . I have to say, it is a pretty troubling time over here in the us. We are seeing people retreat and say they are not looking at the news. People are already starting to say i am confused, worried and scared and i do worry about what that means. Is this now about the loss of control . There are so much of peoples lives which are not in their control. It is another worrying aspect of modern life. I think certainly people feel overwhelmed by technology does it comes to them even when they are not ready for it. You see an update on your phone about something you did not expect. People feel out of control and overwhelmed. There is a huge proliferation. There used to be big blocks of media you could do to four different things. You knew what they did. There is a preferential of all sorts of websites. A lot of them are in high resolution, High Technology sites. They look very ill. How you meant to know if they are real or false . Youre not meant to know. That is the point. There are very Systematic Campaign is now to ensure people see the same messages. Overtime we are seeing networks of information and Systematic Campaign to try to persuade people. It is very sophisticated. As much as we try to teach people to be critical, a lot of these things are really easy to fullback on. The people who benefit are dictators, people who manipulate the news for their own ends. Absolutely. We can see, even within europe and the elections that are coming up with france, germany and the netherlands without huge concerns about Systematic Campaigns quit using Social Networks to change public opinion. That is definitely what is on the cards. How do you counter that . Thank god for the bbc. You looked at gold standard. Touch wood, we have the times, the bbc. Itv and our colleagues. Now, of course, how long that will remain and whether indeed the bbc will, for example, remain independent in the way that donald trump has ensured virtually no State Department can be independent in the usa. That kind of dictatorship, that kind of change in Democratic Politics is very worrying. Then we really do lose our morals. Theresa may was in malta today. She told eu leaders she wanted to build a Strong Partnership with the eu and pledged the uk would be a good friend and ally post brexit. This went down well with chancellor merkel. Better than her relationship with donald trump, which she spent time defending. After publishing the brexit white paper this week, we have a decent idea of what the government wants to get out if its negotiation. But what about those on the other side . 0r policy editor, chris cook, has been speaking to the eu competition commissioner, margrethe vestager. Trying to find out why we still know so little. I think it is important that we leave some things for the people who will be in the room. The eu negotiator, the uk, and Negotiating Team because they will have to put together a new puzzle because some of the obvious signals from the uk government is that they want a new relationship, not the norwegian, not the swiss, not what we have seen so far. Therefore i am very careful not to prejudge things because i think the people in the room, they will have a task which is sufficiently difficult without the rest of us trying to. From the outside. You have an insight into what britain is planning which lots of people dont have because youve actually seen the undertakings they gave to nissan and youve judged that they werent state aid. Can you tell us what they were . Well, of course we stay in touch with the uk government on issues of this kind, just as well with a number of other governments. The letter in itself, we dont have concerns of state aid being handed out. You dont think that while were eu members at the British Government is committing funds to nissan which wouldnt be available to other, Similar Companies . That would be a very broad thing to answer. In the letter and the debates we have no concerns. Is there any public spending involved in this . We literally have no idea. Well, ithink, eventually, probably you will know. But, for us, having seen the letter, we have no concern about what has been going on. Of course we stay in touch. That is as well as we stay in touch with the number of other governments and member states. Is your understanding still that the commissions intention is that well have like the divorce proceeding and then in brexit terms and then a Trade Negotiation . That is the most simple approach. The figure out where you stand and how you move on foot of it is a complex thing to be divorced and having some kind of partnership at the same time. Isnt part of the problem with this that the two things are not going to lie one to the other . Nothing will be decided until everything is decided. There will be things we want in the subsequent relationship but you might want to serve early. It seems very hard to disentangle these two things. These negotiations will be extremely complicated. Maybe you get something in between. To some degree, you can say this will happen to be solved also in a future relationship. This is definitely something where we will have a clean divide commits this can be done now. I think all of these details, they will have to be solved in the room. Not because discussions around the room. But because the responsibility of getting it right is exactly for the people who will be asked to do the deal. Time now for viewsnight, a new feature of newsnight. All week weve been bringing you new thoughts and ideas from a range of opinionated people. You might agree with them, disagree, orthink again. Theyre designed to kickstart a conv tonight, the british senegalese activist and business woman mariam jamme. Britain must wake up to the power of africa. Africa is no longer a colonial subject. It wants to be seen as an Investment Opportunity britain is losing out on, often because of our prejudices. In a world where the Centre Of Gravity is moving from america to china, china has organised the power of africa from investment, to empowering its human capital. Between 2004 in 2009, Chinese Investment in africa has grown by over 40 annually. Africas middle class is booming. 34 of the african population is middle class. Its Consumer Spending is expected to reach 2. 3 trillion by 2030. Manufacturing jobs are moving to africa. Made in china will become made in africa. Africa could be the future for theresa may if europe closes its door on britain. Its combination of micro economic growth, steady democracies, a Rising Consumer class, and abundant Natural Resources make it the perfect Investment Opportunity. Some African Development experts argue that in fact the uk must leave the eu in order to enable our mother continent to negotiate a more equitable Trade Agreement with the united kingdom. Britain is moving in the right direction. Uk investment in africa has more than doubled between 2005 to 2014. From £20. 8 billion to £42. 5 billion. But this movement is far too slow. If theresa may doesnt recognise the future of africa in a post brexit world, it will only harm the british economy. The widely respected head of the American Organisation human rights watch, ken roth, expressed his surprise this week at the appointment of the new deputy head of the cia. As you might have noticed, we follow trumps moves closely on this programme, and at the risk of breaking bbc rules on bias, we can say we were pretty shocked as well. Mr roth was concerned that the new deputy had previously been connected to running a cia black site for torture. We were more concerned at the double identity of those closest to us here at the programme. Emily has issued a kind of denial, but whatever the truth of the allegations, we here at newsnight fully support emily in her life choices. Before we go, you may have read in the papers about the ongoing vegetable crisis. Storms in the med have left us without fancy foreign imports like lettuce, broccoli and aubergines. Never fear, however. This sceptred isle has weathered fiercer storms than this. There was once even a time when, yes, we had no bananas. Weve ransacked the archive to find some advice from that more austere time. So, here are some useful pointers when attempting to cook that decent, honest, british vegetable that never goes out of season or fashion the humble cabbage. Goodnight. Sallys cabbage has been cooked in little water with the lid on, retaining the full value of the vegetable. Sally carefully pours the water into a cup. It is useful for making gravy. Jane, on the other hand, has drowned her cabbage in water and apart from losing the goodness, that cabbage is a wet soggy mess with no appeal to the appetite. Stop that. Stop it now, now, now, boys, whats to do . Whats to do . I dont like this mess. Davids is much nicer. Divide this between you. Now, never put so much water in the cabbage again, it makes it soggy and taste nasty. But youll do it quite all right tomorrow. All right, grandma. Hello and welcome to sportsday im Lizzie Greenwood hughes, heres whats coming up tonight. Deputy dan steps up to win britains Opening Davis Cup singles match in canada. Stoke admit new signing Saido Berahino served an eight week ban at west brom last year. And the six nations get under way this weekend. But still no victory for scotlands women who havent won since 2010. Plenty coming up tonight. And were starting with the tennis because Great Britain are 1 0 up in their Opening Davis Cup tie of 2017 against canada after dan evans won the opening rubber against the 17 year old wimbledon junior champion denis shapovalov.
