Arrested, according to tunisian authorities, four linked to the attacks, the Prime Minister identified two suspects by name saying on french Radio Station atl, one had been known to security services. The two gunmen killed recruited at a tunisian mosque in september and trained at a jihadist camp in libya. According to tunisian interior official. Who told a french broadcaster tfi the Security Forces worked quickly, killing them before detonation. President obama called asepsi on thursday offering continued support during the investigation. Youre going to see the lowlevel attacks, but highimpact attacks, it will not be long before it comes to the United States because it is so easy for isis al qaeda, any other of these groups to do. Crowds marking it tunisias Independence Day are gathering in the center of the city of the capital here. Its always a big event in tunisia, this year many hope the rallies will also a symbolic gesture of defiance against those they now believe threaten this countrys very existence. Michaela . We saw those march at the wake of the Charlie Hebdo massacre in france were seeing the same thing, people rallying around their countrymen. The attack is raising fears about the islamic states reach. A new cnn orc poll finds 80 of americans consider isis to be a serious threat to the u. S. Way up from 63 who said the same in september. Want to discuss this all with phillip mudd cnn counterterrorism analyst and former c. I. A. Counterterrorism official and Lieutenant Colonel james reese, cnn Global Affairs analyst and retired Delta Force Commander who joins us from overseas. Theres a bit of delay, so well be patient with that. Colonel reese, lets start with that were learning that the attackers killed by the tunisian Security Forces were wearing explosive vests that did not have time to detonate. Does this fit the style of isis to you . Good morning, michaela from baghdad. It does you know weve seen throughout the years, that these attackers, theyre well trained, they go to the safe havens such as libya, they get some very good training. But they also realize that once they get into these assaults that the chances of coming out of there alive are slim to none. So that really putting the suicide vest on is their last chance bastion to go ahead and conduct a secondary dynamic explosion when forces are coming in to wreak more havoc. So yes, weve seen it and yes, i believe well see this other places throughout the middle east as we go forward. Phil mudd i know that weve learned that these two men that were killed by tunisian forces, they had been radicalized in a mosque in tunisia. They had trained in libya, were finding out now. A, does this fit the profile . And b, do you believe this claim that this was isisrelated . First of all, i believe the claim that it was isis related. That word related is critical. Back 15 years when we had al qaeda, they would have more tightly controlled this. You would have said an al qaedacontrolled operation. Now what isis is doing is sort of sending out sparks of this kind of islamist revolution to groups that dont have close connectivity to the center. But they believe in the ideology. So i think this is a spark of isis. Its not controlled by isis. In terms of the people radicalized in the mosque and trained in a neighboring country, that is libya, think about two things here. The revolution in tunisia meant looser guidelines on what people could say. Freedom of speech. I think theres a lot of tunisians who are saying wow, freedom of speech brought us the ability to have somebody in mosque radicalize a youth like we saw in this situation. In terms of the training final point. If you look at tunisias final geography, algeria on one side, a lot of instability for years, libya on the other side a lot of instability. If youre sitting in the middle of that. You got to be worried after this incident. Some 3,000 tunisian men and women have left or well we dont know if theyre men and women we know that 3,000 have gone to libya or to iraq and syria. Let me ask you about this carnage specifically colonel reese. The fact that so many people were killed in what seems somewhat spontaneous. But it was clearly targeted they struck at the very heart of tunisias economy tourism. There was a real message being sent there. Yeah there is. Throughout the middle east especially in some of these religious places around the world that have these religious Historical Places this is one of the things that isis or dyche can affect the economies, they can affect the tourism of people coming in. It affects everyone down to the taxi drivers. I think it will affect other places around the world and governments have to take a hard look at how theyre going to stop this. Weve got new polling out, it measures the temperature of american sentiment and tolerance of whats going on. Maybe we can pull some of those up. In the last six months the level of concern that americans feel for isis has gone up 12 . If you look at it now, back in september it was 68 . Now 80 of americans feels that isis poses a serious threat to the United States. The white house has got to be paying attention to that. The concern of the americans is growing. Their concern is growing. I watch that phrase serious threat. To me theres a substantial difference between concern. Im a professional im concerned about this as a serious threat. Im part of the 20 , im part of the minority here. Let me be clear why. Americans are responding very emotionally to this as they should. But, but if you look at the metrics if youre an analyst as i am you got to be coldblooded. Metrics would tell you, ive got ten nieces and nephews, what is the impact on an American Family and how do you rate this against things like the fact that educational standards in this country compared to the west are okay theyre not great. Were talking about a generation of youth that might have lower Life Expectancy than i have were talking about synthetic drugs introduced in schools that are cheaper, but deadlier. Youre saying compared to bigger realities that americans face at home, we dont need to put isis in a category they dont belong to. Correct. You should be concerned because this is a group thats had time to blot theyve been around for years. But if you step back and say how do i measure concern about things that might affect the child, i would say you might even consider not putting this in your top ten. Its not going to affect a kid in a grade or high school thats my metric for how to measure concern. That may be something we need to hear especially from somebody who knows whats going on and has a true read you both are great analysts we appreciate it phillip mudd and Lieutenant Colonel john reese. President obama zeroing in on irans youth, urging them to pressure their leaders to accept a nuclear deal with the west. The president made the plea in a justreleased Youtube Video, this as the Nuclear Talks in switzerland seem to be hitting a road block and a deadline. Just 11 days away. Cnns Senior International correspondent Nic Robertson right in the middle of the discussions in switzerland. Good morning, nic. Good morning, john the talks slipping a little bit. This morning Prime Minister zarif, the iranian Prime Minister and foreign secretary john kerry have not sat down yet. Thats expected soon. President obamas message to the iranian people now is the time to make an important choice. This is what he said. Irans lead verse a choice between two paths. If they cannot agree to a reasonable deal, they will keep iran on the path its on today. A path that is isolated iran and the iranian people from so much of the world. If irans leaders can agree to a reasonable deal it can lead to a better path. The path of greater opportunities for the iranian people. Now, i asked the Iranian Foreign minister this morning, if theres still time to make a deal before the deadline. This is what he told me. Do you think a deal is possible by the 31st of march . I think a deal is possible any time. It depends on the political will whether its a political will to reach one. Its possible. Interesting, because his talking about political will earlier in the week the iranians have been talking more about the need to make ground on technical issues. Secretary of state john kerry has said all along its time for political compromise tough choices on the iranian side about president obamas message. Zarif had his own message that he had tweeted earlier. He told me when i asked about it he said it is high time for the United States and its allies to choose putting the choice here back on the United States for the United States to choose pressure or agreement. The indication there, a big pushback from the iranian side if the United States john kerry wants to get a deal here he needs to stop pressuring the iranian side. Alisyn . Nic, its all so complicated, thanks so much for explaining it to us. And theres a new complication in u. S. israeli relations this morning, president obama calling Benjamin Netanyahu yesterday, to congratulate him for winning reelection two days after the fact. But he also issued a warning to the Prime Minister. That the u. S. Is now reassessing their relationship. We have complete coverage beginning with cnn White House Correspondent michelle kosinski. Whats the word there this morning, michelle . Well this time it was Benjamin Netanyahus turn to get schooled by the white house. Which very publicly said that words matter. And that there are consequences. I mean the president has now called netanyahu and there was a word of congratulations. But he also brought up these highly controversial things that netanyahu said just before his reelection. Namely namely that he said there would never be a twostate solution with palestine while he was Prime Minister. And that his supporters should counteract all of the arabs going to the polls in droves. As he put it. The white house calling this divisive saying it erodes the shared values between the u. S. And israel. I mean the press secretary mentioned no fewer than 19 times yesterday during the press briefing that as a result the u. S. Is now reevaluating its position moving forward. Even though netanyahu has now walked back virtually everything he said. Listen. Now the Prime Minister of israel says earlier this week days before an election this is a principle he no longer subscribes to and his nation no longer subscribes to. That means the United States needs to rethink our approach. That this that steps that this principle has been the foundation of a number of policy decisions that have been made here. Now that that foundation has been eroded it means that our policy decisions need to be reconsidered. And part of that reevaluation, the white house says does include the u. S. Constantly standing up for israel in the u. N. If any of this upsets netanyahu, well he always has House Speaker john bainer to talk to. Who has Just Announced he is going to go to israel within the next two weeks, and meet with netanyahu. Michaela . All right, michelle certainly one that well be watching. The israeli Prime Minister has apparently had yet another change of heart. Now that all the votes have been counted. Lets turn to Oren Lieberman live from jerusalem. Oren . Youre right to point out the timing or the aspect of timing to all this. It was right before the election as netanyahu was trying to play to rightwing voters he said there would be no palestinian state. There would be no twostate solution as long as he has the premiership. As long as he is Prime Minister. He could have corrected our impression of it that night. He had time the next day when he released statements on facebook urging voters to get out there. Instead he waited until after the election. In terms of what israelis think, netanyahu was polarizing before he will be no less polarizing of a figure after these comments. In terms of what the palestinians think, the other side of the issue. We got a chance to sit down with dr. They dont believe netanyahu is interested in a twostate solution, they dont believe hes interested in negotiations they will do what theyve been doing, pursuing statehood through the international arena. Through the u. N. Through the european recognition, so john we could learn what the word reassess means sooner rather than later with the palestinians pursuing international recognition. Thats a very loaded word. And a very long relationship Oren Lieberman for us in jerusalem, thanks so much. New developments concerning the uva student whose bloody arrest was caught on camera.
