Countering them by empowering the overwhelming majority who believe in British Values of democracy is the rule of law and respect for minorities. The department of Homeland Security says, quote, it is unaware of any specific credible threat to the u. S. Homeland from isil, which is another name for isis, and the white house says its working with its allies in watching the situation closely. For a number of months now, we have been monitoring those individuals that have western passports, that are citizens of western countries, other than the United States or in europe, who have made the decision to travel to syria or that broader region, taken up arms alongside isil. They pose a threat because they are theyve received military training, theyre battle hardened, and they have a willingness to rick their lisk for their cause. A string of unsettling developments. Reporters gained access to what theyre calling the isis laptop of doom. Buried inside hidden files of the computer found in syria were videos of osama bin laden, bombmaking manuals and a treasure trove of other documents, including plans to enleash a biological weapons attack. A report in the Washington Post about slain american journalist james foley. Citing unnamed sources, saying that foley was water boarded by his isis captors. Least three other captives reportedly subjected to the same torture. Lets first head to london. Our karl penhaul is there. Karl, see veeshvere, the secondt level, it means they believe an attack is likely. Tell us why they made the decision, why theyre doing this now. Absolutely. In fact, its the highest threat alert that british has issued in the last three years. It means that a terror attack could be highly likely. Prime minister david comb ran we cameron went on to specify theres no specific intelligence any threat is imminent. He referred to the fact that Intelligence Services believe more than 500 britons are in syria or the iraqi region fighting for jihadi groups there, and that really, especially in the wake of the james foley execution and the suspicion that his execution or one of his excusers may have been british, that is what is driving this alert. Now, of course, the idea that british jihadis are fighting in syria, iraq or afghanistan, is nothing new. That has been going on for years. But certainly, nothing more than that seems to be at the core of this. Prime minister cameron did go on to say that he has a number of measures in mind, both to fight radical islam abroad and also on the home front back in britain. What hes looking at doing in britain. He said he would give more details in parliament next week. Perhaps travel bans for individuals suspected of trying to travel to join jihadi groups, possibly also withdrawing some of their passports. What he did also spell out was this could be a long drawnout fight. In his words, he said this could be a generational battle that could take years or even decades, brianna. Yeah, and you heard him there, carl, really managing those expectations by saying that. He was also talking really tough. How do you think thats going to play out on the streets . He certainly was playing tough. These are tough fighting words. Obviously, a lot of the measures hes got to get through to tackle the problem may have to go through parliament. He also later on in the speech referred to the fact that it was a duty of those People Living in britain to adhere to British Values. He didnt take questions on what those British Values specifically were that he had in mind. But that may not play out that well on the british street, especially in multicultural communities, in some of britishs largest cities. A lot of british muslims may see that as a suggestion that it could be an attack on their clothing, the kind of clothing. Are they going to be allowed to wear veils on the streets of british . Or do they have to adhere to a british set of clothing . Will they be able to carry on in the way they do right now with their beliefs, with their religious beliefs . All that up for debate. That said, with some of the people i was talking to over the last few days in east london, british born and bred, were saying they do fear this multicultural britain because they dont like the fact that some britains now may speak another International Language in their corner store. They dont like perhaps the fact that women are walking down street in veils. So those words by cameron may go down well on some fronts but the question is, now, is this going to be an attack on the multicultural value, of some british cities, brianna. Karl penhaul, thank you. Britain raising its terror alert level coincides with writings from al qaeda. The british newspaper the telegraph reports that al qaeda in Arabian Peninsula has published a manual on how to make car bombs and suggested potential targets including the sandhurst military academy, thames house, mi5, department stores, new york citys times square and las vegas casinos. Lets bring in our guests. Also tom fuentes, former fbi assistant director. Tom, this decision, we know its been made. You heard carl say this is the highest threat level in three years. What goes into a decision like this . Are we write to be so alarmed by it . Well, i think, brianna, a big part of this is britain, like the u. S. , other western european countries, have been watching the growth of isis and fearing that, well, okay, theyre fighting battles in syria, other terror groups like al nusra in syria, then going into iraq ton fight against the shialed iraqi, under maliki. Now theyve come to realize they have 500 of their own sit zens have realized. The u. S. Realizes at least 100 from the United States have traveled there to join the jihad. Theyre realizing those citizens can come back, because the travel into syria and into iraq really is not trackable. If they go to turkey, they can sneak in. Its so porous. They could go to greece and charter a boat and go across the mediterranean and land on the shores of syria. No one will ever know. When they come home, it wont be in their passport they visited syria or iraq. Thats the threat. Thats the concern, that theres no way to track. Obviously, we know some of these people, right, tara, are being monitored, but at the same time, how can the u. S. , how can british, how can european nations monitor all of them and not have someone slip through the cracks . Exactly. On Something Like this, where you see the threat level go up, there is probably some type of reporting, some type of concern. What analysts are doing, theyre looking at three things. Theyre looking at what are potential targets, theyre looking at what are potential tactics, and thats just the desire side of the equation. The groups want to try to target. Then look at the capability. Do these groups, the individual, have the capabilities to carry out the attacks they may have the desire to do . Even though we see documents like the ones found on the laptop or the ones you just mentioned pre eed previously, s desire to go after real target, but the next question is do these groups have the capabilities to carry out these plans. Aspirations obviously different than capabilities. But you said there has probably been some reporting. So we dont know what that is then, is what youre saying. We may never know what has spurred this. Exactly. They havent raised it to the highest level, which would be imminent. If you look back to 9 11, there was a president ial daily brief about planes hitting buildings before. That was not specific intelligence. That was not a specific attack. But there may have been types generic reporting about types of plans that groups want to do. That doesnt mean they know a time. It doesnt even mean theres a specific operational plan. It could be, again, just speculating, reporting of that nature that leaves a country in this case, britain, to raise their threat tllevel, or it cou be a fact theres a lot in the news lately about foreign fighters going back and forth and then the video of james foley. So domestic political concerns if they didnt raise it and something happened, they would be negligent. This manual on car bombs posted by al qaeda. This is what the telegraph reported. It suggests potential targets. Speaks to what youre saying, something general even if its not specific. Do you think this is an attempt by al qaeda, is this pr in a way, is this al qaeda saying, okay, everyones talking about isis, hey, remember us . That could be. Competition among the terror groups. Al qaeda in the Arabian Peninsula civentered in yemen he been putting out inspirational jihadi messages for a long time, back when al awlaki was still alive. They put out inspire magazine. Its still going strong. You go back to through the 12 issue, they list dozens of ways to kill people without having to shoot a gun or make a bomb or anything sophisticated. They talk about take a car and drive it up on the sidewalk in washington, d. C. At lunchtime and youll mow down a lot of people and kill them. Hijack a tanker truck and drive it into an elementary school. Derail a train. Theres so many things theyve listed over the 12 issues. And the travel to syria or iraq to learn how to do it, just do it right here and if youre inspired, go forward. Thats an important point. We worry about this mass casualty attacks. We worry about the black swan events that might be low probability but very high impact. At the end of the day, there can be lone wolf actors, mass shootings. Terrorism aside, events that can be carried out by teenagers, small groups, individuals. Things like this are what the Law Enforcement community has to watch out for, which is not the catastrophic mass casualty terror attack we think of. They consider them to be probably more likely.

And nato both say there is evidence of Russian Troops and heavy armor in southEastern Ukraine. Russia says its all a western lie. Here was natos response this morning. Despite moscows hollow denials, it is now clear that Russian Troops and equipment have illegally crossed the border into eastern and southEastern Ukraine. Our Matthew Chance is live for us from moscow. Matthew, theres video evidence, theres satellite images, separatist leaders are admitting that Russian Troops are fighting with them. How is the crekremlin still deng involvement here . Well, theyve denied it all along. For some months now, theres been mounting evidence that Russian Forces are taking part in combat operations inside ukraine. Just a few days ago, ukraine paraded ten russian paratroopers it had captured and detained inside ukraine. The explanation from the kremlin then was theyd slipped over the border by accident after patrolling the frontier. Now, today, the Russian Foreign minister, sergey lavrov, again, keeping to that kremlin line, saying that any kind of evidence, any kind of suggestion that Russian Forces are taking part in combat operation, inside ukraine are purely conjecture. Take a listen to his explanation. Translator from the very beginning of the crisis, we have been blamed for everything. There have been reports that there are photographs from space showing movements of Russian Troops, but as it turned out, it was Computer Games and the images were taken from there. And the latest allegations are more or less the same kind. All right, well, the prorussian rebel commanders in Eastern Ukraine have given an even less plausible, arguably less plausible explanation for the presence of Russian Troops. Theyre saying there are several thousands of them fighting alongside ukrainian rebels against Government Forces in Eastern Ukraine. Theyre saying theyre russian soldiers who are on leave of absence from the Russian Military and are simply taking their Vacation Time to fight alongside, in many cases, die alongside the rebels in Eastern Ukraine, brianna. Thats a very odd explanation. President putin, matthew, he has referred to the rebels as the militia of new russia. Why does this matter, this choice of words . Well, new russia or as they say in russian is the russian term for that area of eastern and southern ukraine, which was traditionally part of the russian empire in the czarist times. It was named that then. And of course using that term sort of puts forward a russian claim on the territory. Indeed, thats what the real concern is at the moment. That while this is kind of a thin veil of deniability placed over the presence of Russian Troops taking part or not inside Eastern Ukraine and in southern ukraine as well, whats actually happening behind that veil is that russia may be tightening its grip, increasing its presence in that area to eventually annex it. It did that in crimea a few months ago at the start of these hostilities back in march. One of the worries is it may also be doing something similar in those eastern and southern areas of ukraine as well. All right, matthew, thank you so much. Well, ukraine and russia, iraq and isis, no shortage of Foreign Policy challenges for president obama. But his no strategy comment about isis in syria is raising concern.

Britain raises its threat level in response to the danger posed by the terrorist group isis. Prime minister David Cameron today called isis the greatest and deepest threat to uk security the country has ever known. President obama saying he doesnt have a strategy yet for dealing with isis in syria. The white house in overdrive again today trying to clarify what the president meant. Weigh asked a specific question about whether or not the president would seek an authorization before ordering military action in syria. The point the president made was thats putting the cart before the horse. The president hasnt yet laid out his specific plan for military action in syria. And the reason for that is simply that the pentagon is still developing that plan. Hes still reviewing them. And it would be putting the cart before the horse to talk about whether sort of congressional authorization would be required for a plan that hasnt even been put in place yet. Do Prime Minister camerons actions perhaps put more pressure on president obama to lay out a plan . I want to bring in Gloria Borger to talk about this. Can we kind of talk about the delivering leadership styles in a way just between two press conferences. We see cameron today. President obama yesterday. There was no ambiguity at all in what cameron said. He said isis was a direct Security Threat to the uk. What the president has said, particularly in a recent interview, he said, we have a strategic interest in pushing back isis. So i think you see the different styles. The president is less willing to come sort of straight on and say it. He seems, as a result, less decisive, of course, less direct, more conflicted. You see the president in conflict. Its different, right, because the u. S. , there obviously are some people with american passports who are participating in isis. Right. There are many more in british. It is clearly a bigger issue for them. More of an issue for britain, but one would argue, if, god forbid, there were an attack on britain, it would be an attack on everyone. So, look, i think what you see in the president is somebody who
