and margaret joins us now via skype from the biggest city in the kurdish region, irbil. >> margaret, you have been reporting this morning and throughout the day there have been air strikes near the mosul dam to try to help the kurdish or peshawar regain the area, what have you heard on the ground? >> just as we have been speaking, the pbs reported with heavy u.s. air strikes, u.s. special fors calling in the locations of the strikes, and peshawar fighters with their special forces they have retaken the dam and it is a critical, critical facility, it controls a big part of the water that flows down the tigris river, it can ultimately threaten baghdad if that dam were destroyed as the isis and isil fighters, what they did do another dam earlier question was to destroy it, so it is a huge, strategic, i would say strategic victory for the kurdish, iraqi and american forces. >> so, martha, you are out on the front lines today in 115-degree heat, what was it like. >> what did you see. >> well, hari, we were about an hour south of here to the city which the kurdish peshawar have boasted of

she comes to us via skype from erbil. >> so in the past week, we saw this massive assault by the islamic state, they took over three towns and then just in the last 24 to 48 hours they took over another, what is the latest we know about how they are advancing? >> they have moved even closer over the past few days to irbil, the capital of the iraqi kurdistan and that is really what sent officials here, residents of the kurdish region into a panic, and prompted ultimately the u.s. intervention, there is a large american consulate presence here, there are thousands of u.s. citizens and on the iraqi side there are thousands of yazidis on the mountain side that the iraqi government hasn't been able to help them so this has been, caused u.s. involvement into iraq. >> you got there right before the u.s. air strikes happened, what was the aftermath? what were the consequences. >> when i got here, people were in a panic, the islamic state encroachment on the capital, it is not clear these are actually the goals of these militants, they are definitely making a push all the way across the iraqi kur

he joins us via skype from austin. back from new york, our own cory johnson.me people, this might seem like a regional story, but it is now getting national attention. what is the back story? how did we get to this point? >> rights fees have just escalated. even though everyone outside california things that might be something wrong with the people in l.a. who keep driving the price of tv rights stuff between the clippers and the dodgers, but this is a national story because the price of tv, cable, satellite, has just gone through the roof. it is tremendously funding all of the sports leagues. it has made leagues that were very unhealthy very healthy leagues across the board. so it is an integral part of the major league sports story in the united states. >> is that a function of the technological innovation of timeshifting where you have people recording everything else? that sports is literally the only thing where people have to watch the commercials? [laughter] >> that's probably part of it. my gut tells me as ratings decline and as viewership declines on

he is joining us via skype. so, fill us in. how did this whole thing happen?as he selected to celebrate like this? >> originally it was supposed to be me who i kind of wanted to spotlight, but kevin is one of my best friends, so i asked him to just do it in the middle of the aisle and kind of surprise everybody, including our entire party because they also thought it was me who was supposed to do it, and so he was all about it, and excited. so we thought it would be a nice little twist. >> how did everybody else react to him just jumping up from the video? >> you can kind of tell some people weren't sure what was going on, but i think they started to kind of get a hint. the dance moves are pretty unique, so i don't know if people thought he was having a seizure or dancing. >> did this set the tone for, like, an awesome reception? >> oh, yeah. i mean, we're considered the fun couple, so that was kind of how we wanted to start everything off, started off with a big bang. >> grandma now a little lil john fan. >> oh, yeah. >> you guys are on your way to the honeym

. >> we've got them both joining us via skype, eric and larry. e to the show, guys. >> hi, guys. how are you doing? >> tell us about the search. how rare is this car? how tough was it to find it? >> really hard. you know, since i was a child growing up, my dad was always looking for the car. and there's so few of them made. i would check ebay and a bunch of different search engines and finally found it. and then we kind of tricked my dad. and i showed him a picture. he said yeah, that's it. is that car for sale? i said nope, not anymore. someone already bought it. we just miss it had. >> what do you think of your son? >> it's amazing. it's what a father would hope for that would be so concerned for his father's happiness. >> describe how you become so emotionally attached to a machine. >> there aren't too many kids taught how to drive a car at that young age. there was one time we were driving across nevada on a trip. i was driving 80 miles an hour at night. i looked around me. my mom and dad were asleep. my older sister was asleep. and here i was

she stayed up really late for us and join us via skype from atlanta. really appreciate it, holland. let's talk about robin williams. his rep did say he suffered from severe depression that could have contributed to his suicide, we don't know for sure. avoiding rumors, what do we know about his emotional state recently? >> we do know as you said that his rep did confirm he had been suffering from severe depression as of late. he had recently checked into a rehab facility in the last month to maintain his sobriety is what reports are saying. we do know that in the last few years, in 2009, he had heart surgery which may have contributed also to his severe depression at this time. we know that he was discovered from apparent asphyxiation. i guess reports will determine that at a later time as well. >> so sad. what do we know about the other projects he was working on? multiple projects. we've kind of been discussing here "night at the museum 3" which i think was already completed. a "mrs. doubtfire" sequel we've been waiting for, what do we know? >> we wer

he joins us via skype from erbil. thank you, sir, for talking with us.here are of course so many layers to this story. but we do want to start with this political crisis that of course threatens the nation. prime minister maliki refusing to step down despite the naming of his replacement. what has been the overall reaction to the naming of haider al ibadi, and will he be able to unite the nation, something maliki has certainly failed to do? >> well, this is not surprising that prime minister maliki is going to try to hold on to the prime ministership. he has amassed a lot of power over the last eight years that he's been prime minister and amassed a lot of wealth. he also has some militias, shiite militias that are loyal to him. he reportedly has moved them around the green zone now. and he's going to contest this new development. you see that haider al ibadi has a great amount of support outside of iraq from allies to iraq like the u.s. he also now has a great amount of support inside iraq. most people and most groups and political parties in iraq belie

david kennedy, who used to work for the nsa, joined us via skype. i asked him is hacking a plane really possible. >> systems are supposed to be independent. unfortunately, if you put the communication on the same network as wi-fi and you can hack into communication systems and cause a blackout on the actual airplanes -- [indiscernible] it is damaging to see that. or the actual dvr systems. >> are you saying for a skilled hacker, it's pretty easy to do? >> that is the problem. these are things that are default passwords. passwords that are known you can log into. it does not even the -- you do not need to be a skilled hacker to get into the systems. what it shows that sourcing these products from a lot of different companies and are not passing the security and [indiscernible] more connected systems and things like that that introducing more risk. >> david, what is the state of it right now? every year, there are more systems and more freak out woe. what is the state right now? >> black hat is the largest hacker conference in the world and that is wh

he has studied atlantic city gambling. .e joins us via skype i want you to lay out the landscape. what is the economics right now of operating a casino in atlantic city? >> atlantic city is a very troubled area from a gambling perspective. gambling revenue has declined from over $5 billion in 2007 to under $3 billion today. that is about a 40% decline. they have three they are going to close if they can sell themselves to someone else. >> how did they get into that situation? of factorse a lot that led to that situation. number one was the general economic downturn. ,ess discretionary spending less available funds to go to atlantic city for a while. with the effects of hurricane sandy that are still being felt along the boardwalk and atlantic city right now, that coupled with the fact that the gaming market is expanding in other areas. pennsylvania has moved them out. they are going to give atlantic city and cross giving in new york state -- there is additional competition for the way -- for the dollar. i think what is going to happen eventually is you are going to see a much smal

she joins us via skype from montrÉal. thank you for joining us.w would you describe anonymous's role in this -- these protests and the situation in ferguson so far? has laid a couple of rolls. they have amplified the role that the media played, which is getting the role -- the word out , having people be able to participate and know what is going on. and they did this largely on twitter by providing live updates and pictures and rallying calls, but they go no further than that. by releasing names of officers involved, whether that was the name of the chief of police in , releasing his name and that of his family, and then noted, theg as you supposedly said who shot mike brown. >> i wonder, behind-the-scenes, how are they organizing themselves? how will they discuss whether to release this information once they have obtained what they believe is correct information? historically, in some operations where they have been releasing names or incrementing evidence, they tended to organize by very small teams. and they would work with locals in the area,

. >> peter monsour is joining us via skype. thank you for joining us.cker said yesterday i believe we should launch air strikes and they should be heavy and immediate. do you agree with that? >> ryan crocker was ambassador to iraq with general petraeus. they formed a very effective team in 2007 and 2008. he knows what it takes to destroy a group like this. al qaeda and iraq was the forerunner to isis which we nearly destroyed during that time period. we have teen this kihave seen t. we cannot allow it to spread. i think he eventually need to destroy it. i think we need to hit the group, but a more holistic tragedy than air strikes. >> let's talk about the holistic strategy. air strikes would help, but it would help to have ground troops, not u.s. troops, but troops to finish off that job. we talked about secretary kerry's op-ed, but there are ones from senators mccain and graham. they said to go after assad at the time in syria for years. do you think if the u.s. had armed maybe the free syrian army there that this would have stunted the growth of isis

a dartmouth economics professor and a former member of the bank of england joins us via skype from new hampshire and from washington, d.c., a senior fellow at the peterson institute for international economics. let's begin with you based on what you have just heard from michael mckee regarding mario draghi. is mario draghi in a position to do anything other than talk about rates? >> well, he could do some quantitative intervention and buy various assets. the question is whether he would want to do it. >> mario draghi has also got to contend with a multi-speed european economy. the german economy different from what is going on in spain, greece, and portugal. when is he going to recognize getting them altogether is part of what has got to happen? >> i think he has to look at the data. you are right. we have seen weakness in spain, greece, italy, and portugal. now we are starting to see weakness in germany and france. yes, he has talked about what he can do. you said it right. it looks like europe is where the u.s. was five or six years ago. they have had five or six years to sort out wh

he joins us via skype. hacking an airplane? is that possible? >> it appear so. there is a security researcher ruben who looked at the in-flight wi-fi, which is what allows you to communicate with your laptops. normally the systems are supposed to be independent and separate. unfortunately, it looks like they put the communication [indiscernible] on the same as in-flight wi-fi and you can hack into the system, causing a blackout on a plane itself, or even [indiscernible] there wasn't a lot of security put into these in-flight wi-fi systems or the actual dvr systems they have inside the airplanes themselves. >> for a skilled hacker, do you think this is pretty easy to do? >> that's the problem with this. aree are things that default passwords, passwords that are known that you can log into. arendt a security practices. you don't even need to be a skilled attacker to hack into these in-flight wi-fi systems. they are shows is that sourcing these products from a lot of different companies and not even testing the security around them. connected toe systems like that

joining us via skype is a former fellow from the european institute from security studies good to have you with us. >> thank you. >> where do we stand a year later. >> out all the declared precursor chemicals have been removed from the country. a large amount of that has already been transferred to commercial insinerators in finland and the united states and the u.k., and the u.s. vessel is currently in the mediterranean, busy with the neutralization. it is my understanding that all the precursor chemicals have been neutralized and only the mustard agent is available. >> what is next in the process. have we met the time lines. >> what we are going to see is that the o.p.c.w. is going to interact with the syrian government concerning a number of outstanding questions. this is more part of what i would call a normal verification process. similar issues occurred with other countries. in the case with syria, we have to deal with a situation, and, two, because syria used chemical weapons until last summer, and perhaps in the spring, the answers will have to be more stringent than what other

. >> joining us via skype is chris gunnize, senior director and spokesman for the relief and works agency, with 13,000 staff. thanks for joining us. israel - good to have you with us. israel's unilateral and partial ceasefire in gaza ended late in the day, on monday. it allowed displaced palestinians to return to their homes and get badly needed medical supply and food. how bad is the situation, the humanitarian situation in gaza right new? >> first of all, only a small number of people managed to get back to their homes, shelters in gaza. 90 shelters have 297,000 people. we estimate the overall figure for displaced people is 475,000. about a quarter of the population of the gaza strip. also a problem is displacement. and don't forget people that get back to their homes will find them badly damned, and possibly are going to homes not connected to water and electricity, because the water and electricity supplies have been badly damaged. there are huge, huge problems. that's why we say the humanitarian pauses, ceasefires, have got to be and must become permanent peace, because without that,

an iranian journalist and political analyst joins us via skype. good to have you with us.king at the numbers of the iranian lawmakers. there were 145 who actually voted to impeach him and 15 abstained. radio these the numbers that the hardliners wanted to see? >> well, it's not about who really is or against the impeachment of the minister. i think he deserved every minute of it, because he wasn't qualified. he made many mistakes. he appointed many university heads without any approval from the intelligence ministry and other official bodies, at the same time, he appointed many university heads without even consulting the intelligence ministry and other political organizations. >> but nearly half of them are -- ok, but nearly half of the lay makers said that they didn't want to impeach them, are these the numbers that the conservatives in the parliament wanted to see? >> well, it is not as they expected, but they have damning evidence against the minister. i think he did a very poor job over the past nine months and he is not the only president that needed to be impeached.

joining us via skype by a ann arbor michigan. the most pressing question that our viewers probably have is the islamic state group a threat to the united states? >> it's not an immediate threat to the united states. because it has local ambitions. it's holding territory, it's trying to take more territory. it's developing a governing bureaucracy. so in these radical groups you know there are two theories that you get ahead by attacking the far enemy first and that was al qaeda or that you attack the near enemy first and that is the so-called islamic state. but in the long term of course it is a vicious organization. very dangerous and very anti-american. so it is a threat. >> senator john mccain wrote an op ed that we were looking at earlier today. this is what he said when trying to decide what the u.s. strategy should be. he said it should look like this. this should be more like afghanistan in 2001 where limited number of advisors help local forces with air strikes and military aid to route an extremist army. no one is advocat

jeff, there you are with us via skype. so one has to wonder, if there's a way in which you can express kind of the culture of this dirt track racing, what would prov e provoke, you know, a driver to get out of his vehicle on an active raceway even though caution flags have gone up and these cars are going slower, clearly there was some kind of altercation or we know there was contact between tony stewart's vehicle and kevin -- kevin ward's vehicle, but why would someone get out and get on the track in your view? >> well, when you're in a competitive situation and someone in auto racing runs into you, causes an accident, you get pretty frustrated. i've done this myself. i think most every driver around the world would probably say they've done it at least once in their career. you get out and you want to show your frustration, displeasure to the driver that might have done this. so yu get out of your car, you get next to the racetrack. as they go by, you shake your fist, you make gestures to show them you're not happy with

a journalist at "the weekend argus" joining us via skype from cape town in south africa. >>> armed forces from the african union launched an offensive against al-shabab in somalia. it's the latest phase of the continuing operation against the armed group targetting opposition near mogadishu. the operation is aimed at denying al-shabab access to the sea to cut off weapons trafficking. >> let's take you live to milan in italy where the european union foreign ministers are speaking about the situation in ukraine, let's lich to katherine ash -- listen to katherine ash, the special envoy. >> we are clear there's no military solution to this crisis. we need a sustainable political solution, but respect ukraine's integrity and topography. we urge russia to stop hostilities, to stop the flow of arms, equipment and personal into the conflict region and withdraw sources from ukraine. i will report discussions and meet with petro porashenko, who is in brussels, and european leaders will discuss how to act. we is spent time talking about the events. ministers condemn the actions of i.s.i.l., and agre

joining us via skype is dr. mas gilbert, a doctor, caves and politician. he was volunteering add shifa hospital. doctor thank you for joining us. the letter you sent to u.n. secretary-general ban ki-moon, in which you asked for a safeguard evacuation for the wounded from gaza. you are calling for an air evacuation corridor. explain to us what you mean tbhai. >> well, we owners about that. >> we wrote this letter, three norwegian doctors that have worked in shifa during this war. the hospital he are completely overwhelmed with patients, and shifa have 40 intensive care patients who have been saved and operated but need desperately follow-up advanced intensive care treatment. the hospitals are so full that they cannot provide the necessary treatment to all the wounded in particular the children. so what we asked ban ki-moon is to establish an air bridge so that patients can be air lifted from shifa and goofs city and advanced treatment outside of gaza and also that there will be a safe corridor for ambulances to transport patients between hospitals. we know h

. >> joining us via skype from freetown, sierra leone. >> you have been there for some weeks. how is the situation on the ground? are there any signs of any kind of improvement? >> shul things are improving. when i first got here, big problem was that people didn't believe ebola was real. there wasn't a widespread campaign to convince people that this was a national emergency. >> that's different now. people believe it's real. people know that it's serious. they have seen a lot of the deaths. they have heard about big problems and people take it a lot more seriously. so things in terms ofs understanding the disease and appreciating how deadly it is are out there? >> one of the most moving parts of your article was talking about the young men who call themselves the burial boys who have taken charge of burying the bodies of the dead. talk to me a little bit about the kind of challenges they are facing in their communities and the shunning that's going on. >> i spent about three or four days working with them, going out on their regular rungs. i would say after three days, i was

lieutenant general mark heardling, former xhapder of a task force in northern iraq and voyages us via skypem orlando, florida. thanks for talking with us. we're seeing this two-pronged effort now, respect we from the united states, the humanitarian air drops which have been did done and now the threat of targeted air strikes. they haven't as far as we know taken place as of yet and they will only take place, we hear, from president obama if isis threatens american personnel in irbil. how successful do you think it will and should the air strikes have been conducted at the same time as the air drops to make sure isis doesn't get their hands on this aid? >> i think certainly the air drops have been protected by close air support. that was stated by the department of defense this afternoon. they didn't have to strike but there certainly was aircraft protecting those drops. in terms of simultaneity, he's protecting lives and the consulate in irbil. that's priority number one to assure american lives are protected but at the same time the second part of this equation and very complex situation i

i would like to welcome harvard kennedy school professor of international affairs, who joins us via skypethank you for joining us. let me ask first about the fact we are running what seems to be recon missions in serious now in the military. does that mean it is not long before the military gets involved with airstrikes there as well? >> that is clearly the preparations being made, whether or not president obama will ultimately decide to ask and involvement into serious, it is a decision for the white house. another thing to bear in mind is airstrikes can really only have on a group like isis. there are a lot of ways for them to disperse and make it difficult for them to attack. the problem will not ultimately be solved by air power. >> which means, we have got to put boots on the ground and move ground forces into not only serious, but iraq as well? >> probably not. you will remember we have 150,000 troops in iraq back at the height of american involvement, and we could not control iraq's internal politics. the idea we will go back in there and solve the government's problem is fanciful.

jacob ward joins us via skype from oatland. good morning to you. this hit before 4am your time. what did you feel? >> good morning. it was a very distinctive feeling, we slept through several earthquakes an i can't remember, and the experience i describe is that of a truck bumping into your house. you feel a certain quick jump. this was not that. this was more powerful. my wife and i were woken by a powerful side to side motion that had us grabbing for one another. other people are reporting locally that they jumped out of bed. certain neighbours had that feeling. the damn is certainly not extending as far south as where a. i'm about 40 -- as where i am. i'm been 40 miles south of the canyon, near napper, that part of the area is showing buckling in the roads. the california highway patrol is reporting the closure of highways around the area. where i am, the infrastructure survived. if you can see outside my window, the lights are on, everyone is asleep. i am sure they are checking twitter. >> don't go anywhere, in case we need to come back to you later in the programme. thank y

right neighbors likely to murder my family and i can ask how can i make a liberal world joining us now via skype is jay bakker the leader of the emerging church movement he's the son of the thing televangelist time if a and jim baker what is the emerging church movement. well i mean it's a progressive group of people who are afraid to ask questions. who do believe in science and aren't afraid to doubt or you know be curious but do you continue to believe in a god. i would say i have more faith than i do believe meaning was the difference well i believe faith holds the idea of perhaps and it belief is though something i can see and touch and put my hands on and the faith this kind of the bible says it's the evidence of things not yet seen so it's more like hope just so my agnostic. if i was an agnostic i'd say i was a christian agnostic. i don't know but it's sort of. a who are a problem really more people like you than a willing to admit it what are you views on that dr krauss well i think you know in fact i think that's probably many people call themselves religious or just like j. i mean they

. >> oxfam's spokesperson joins us from gaza city via skype. thank you for joining us. i know that oxfam has been warning that gaza is on the brink of a major health crisis. what is the situation where you are? >> the situation in the gaza strip continues to deteriorate because of the continuous military actions that have taken place. this has an impact on basic services serving the gaza strip, including water and sanitation. many pipelines are destroyed and continue to be destroyed. this is leaving the population with health risks. sol, especially on the overcrowded schools are helping thousands of family with spoor water and sanitation services. we are still warning that the public health situation, and the health situation is on the edge of collapse if the situation conditions like this. >> poor health situation, shortage of food and safe drinking water. what kind of work are you and your colleagues having to do to help these people? >> [ inaudible ] ..clean water to those displaced in schools, hospitals and other places. we include those that fled their houses. we a

he was nice enough to join us from vacation via skype from denver, colorado. or steamboat springs, right? >> that's right. >> thanks for being with us. the interesting thing, we've heard a lot about its surprising results that there was just a one day after taking the serum an improvement in at least two of the patients. you had an interesting story about where this came from and why putting it into widespread use at least right now is an extremely large challenge. >> well, you still have a highly experimental drug. it's great, almost unexpected that it would do so well in the first two humans who got it. it's really only been given to a small number of monkeys, success there. but to bring a drug forward really so you know how to use it, what the dose is, how to administer it, how often to give it you have to test it on a lot more human beings. we might try this drug on children, very old people. what are the doses for them, how they're going to respond again unknown. so very promising, very exciting. but we're still in the early stages of human experimentation
