because when you make the profile of a lot of these jihadi jihadis who left, you have this small criminals, the problem of no jobs, education failed, but at the same time you have quite a lot of jihadi kids who are from well middle class, so it is not only that. it looks like we've lost--a small part, but a part of a generation. that makes it very strange. because syria is near. they go there. they feel this sense of injustice about what is happening there. the double standards in international politics. at the same time they are collective as if they weren't entering some sort of a sect. they're disconnected with their friends, their family, then they left. and then their minds were more blown up over there in raqqa and syria, and then they come back and do these things. >> you talk to mothers who raised their sons in what seemed to be normal environments, fun-filled, good homes, loving homes. what do these mothers say why it is that their sons are attracted to this? >> they don't understand. there is a lot of shame. there is a lot of shame about what their sons did. you must imagine how

they are sympathetic to the jihadi.u going to do with them. >> practical things europeans will do. they won't find the strength of character to do it. >> what are you going to do. >> one, it's about family in that world. so, when you produce a jihadist, when one of your relatives, you know, is involved in terrorism, you lose all government benefits, permanently, the whole family does, including the extended family, including right to subsidized housing. two, they have got to get serious about revoking citizenship of those who commit terrorist acts, including natural born citizens and, third, finally, they have got to find a way. it's going to be tough. break up colonies where the police -- it's not that they're no-go zones it's not want to go there zones like molenbeek and other slums. if you are unwilling to take that on, the problem will metastasize further. >> european nations are not going to do that. they just aren't. >> i'm telling what you it's going to take. >> they are going to be dealing with muslim terrorism.

they are part of the cell or network of jihadi network. we are assuming this of the previous event. what do they want? to force western society, the belgian society, in this case the european union and of course nato to submit what they want in the region in syria, iraq and other places. as greg has mentioned, this is very important. they have targeted allegedly american airlines or american airline. this would be a different dimension if we get that confirmation. >> getting to greg's point and your point as well, we do know various terrorist groups would like to conduct another attack, if not many attacks on american soil. we have been very vigilant about that and we've had very good security here in the united states but we have to be right all of the time, and they can get lucky just one time as is the case that we're seeing right now here in brussels and as we saw previous to this in paris, france. i would ask you should we always try to find ways of trying to penetrate them as opposed to them penetrating us? >> well, that's the game now. that's the war on terror by definition.

this is a recruitment video for deaf jihadis who wish to join isis. tottenhoffer's isis minders kept him away from only one group. he was not permitted to speak to, or even go near, a single woman. >> and you think you would win the war. >> perhaps the most astonishing thing tottenhoffer heard is this. >> they want to provoke the united states to bring ground troops to the country. it's a clear target. they want the americans to bring their boots on the ground. they want to fight the americans. that's their dream. the ultimate fight against the americans. that's what they want. that's what they hope. >> they do want to fight the americans on their own turf. in this regard, isis has a different dream than al qaeda. osama bin laden wanted to perpetrate large-scale terror attacks against the west. isis may do this but to further its aim of building a state. a caliphate. still, you cannot understand isis without going back to al qaeda and its signature moment. it's most spectacular attack. september 11th, 2001. 19 al qaeda operatives hijack four planes, k

"the guardian" called molenbeek jihadi central. you have imoms and others radicalizing them. anti-semitism, conspiracy theories. even when they went to get abdeslam this week, there were some throwing rocks at the police, calling him a hero, et cetera. the bottom line is there is growing circles of influence outside of the terror cells. there are supporting networks. once they catch one, the other networks will become operationalized. before they get caught, they want to go out and on their way to heaven commit a radical act of terrorism so they can say they were operationally. is as jihadis. >> what do we do about that? we sit back and watch this happening? how do we go into these communities and fight what's happening there? >> this is where we need to thread the needle. on the one hand, demand that muslim communities come clean, be transparent, and begin to be part of solving the problem. not only the terror problem but say we are countering violent islamism, political islam, a separatist teaching in the communities, about the c

there were beatings, unexplained prisoner deaths and several jihadis escaped. early 2004 s a new man arrived. we know him now as the leader of isis. yes, he was in american custody during the iraq war. he has shown his face publicly only once, last year, when he gave a sermon to his followers. but back when the u.s. had him under lock and key, he was seen as, believe it or not, a man who could be trusted. >> the americans seem to see abu >> he wasn't considered from everything that we know now a high-level detainee, and he was allowed to, you know, lead prayers, he was allowed to give religious lessons. >> the future leader of isis was giving other inmates lessons on islam. he went through a translation at camp bucca. >> by the time he left he was someone else. >> all we know is he became an entirely different creature in terms of militarization, in terms of building militants in the prison. >> at camp bucca he networked with hundreds of jihadis some of whom would join isis and the day would come when he would need military expertise. entered saddam hussein's a

it has become apparent how many radicalized jihadis a living within belgium and brussels in particular. this "newsweek" article says that abdeslam had been in belgium three weeks before the attacks. we know that was where he fled to the night of the tax, november 13. this is hidden on cctv footage en route to belgium on the 14th of november, the next day. what we didn't know until fairly reasoning was that he had been in brussels for a long time and the question now is going to be was he actually they're all along? we don't know at this stage. in europe a lot of people were talking about how he got to syria. -- had he gone to syria could certainly it is one of the questions that now needs to be answered. the street says the -- this tweet says the way they were able to locate salah abdeslam today was all thanks to what they discovered in the raid on the apartment any forest area of brussels, which happened on tuesday. if we go to "the guardian's" coverage of this one, they talk about the fact that prior to the the in molenbeek, prosecutor said it hadn't been established how all the fing

belgian jihadis exhorting those still at home to join them in iraq and syria.imates vary, but belgian security forces calculate the average number of belgians who have successfully left to join isis are almost at two dozen. the dramatic capture of the so-called eighth paris attacker, salah abdeslam, just a street away from his childhood home after months on the run, a stark reminder of how hard it's been for belgian authorities to stay one step ahead of the extremist networks. and the tide of extremist literature bolstering the networks is proving even tougher to quell. if anything, it appears to be even easier to obtain, cnn, brussels. >> and there will be more exclusive reports all week as she gives us an inside look at the homegrown threat of terrorism, and of losing more children to the lure of isis. >> reporter: belgian security sources tell cnn, that an a average of five to six belgians left to join isis. for the families and the communities they return to, it only exacerbates the fear. >> translator: every sign, every case is different. when you look at

and not only concerned about existing terror cell, but concerned about jihadis coming into the european mainland to carry out attacks. with the capture of salah abdeslam, the worry was the tension because what they know of the networks is when one is taken in, the fear they will be exposed often fast forwards these plots. as it stands, authorities are not speculating. they only confirmed to us the explosions. we are working on getting any sense of what caused it. from what we are getting from a witnesses, there is real fear and real devastation at the scene. >> nima, the belgian authorities released another name of the suspect following the arrest of salah abdeslam. they were looking for him and there was a manhunt for that person. you started your day in molenbeek which is far east of brussels. in between the city where you started your day this morning. i take it it is a target. do you know the security arra e arrangements are at the departure area at the airport? is it easily accessible and were their plans disrupted? is this a target individuals might go for? >> reporter: those are

two things are at play here -- one, pakistan's informant for jihadi groups initially was primarily agic investment which was supposed to bring them benefits through influence in afghanistan and the liberation from india. that has backfired. even though it backfired, pakistan has been selective in going after these jihadi groups and has the reason why the jihadi groups pick up specific targets like shias or amadis or christians as a means of improving their recruitment, playing on polarization and taking advantage of that advance in society further. >> woodruff: pamela constable, how much do we look at this as an extension of what i.s.i.s. is doing in other parts of the world especially in the middle east and how much of this is internal to pakistan? >> i think it's mostly internal, but i think this group even said so. groups like this are taking a leaf, taking an inspiration, if you will, from i.s.i.s. and saying we can go farther and do more. let's get up to the plate here. but it's been going on a very long time within pakistan, sort of creeping up bomb abomb and attack by attack.
