They displayed the National Colors of a country that feels itself at war. It is in mourning today. Remember, isis claim this attack. They said there were eight atertackers but only seven bodies were found. Incatelligence officials believe there may be a specialist bomb maker who constructed the suicide belts relatively sophisticated. One other thing, five arrests in brussels, the capital of belgium. Its pretty clear this is a network and a plot that extends beyyond france. That gives us a lot to talk about this morning. Bill, nice to have you here in person. Thank you. As bill pointed out, all evidence points to isis in the attack. The group has claimed responsibility. The french government said that group is, in fact, behind it, as well. The terror group, however, isnt known for operations outside of north africa and the middle east. So could this signal a new front for isis . Lets bring in nbcs chief Foreign Correspondent richard engel. Richard, good morning. Reporter good morning. As my colleague bill neely was just describing, people here at the French Ministry of justice believe that this was a larger plot. That it was not just the seven or eight or more individuals who attack, that there was a wider International Conspiracy and that it spread across borders. Arrests have been made in belgium. Also investigations in greece, in serbia, and this does represent an evolution for isis. Experts say the coordinated attacks on paris would have taken weeks to plan. Simple, but well organized. The attacks prove that isis was being underestimated. These are only seven or eight people and, yet, theyve inflicted hundreds killed and wounded and dominated the global discussion. Reporter so how did isis, the group that only came to be known to the outside world last year, when it took over parts of iraq and syria, manage to terrorize a World Capital . It appears, based on early clues, that the mass migration from the middle east to europe may have played a part. One of the attackers identified by french authorities by the partial name, abdul akbaq b. , appears to have arrived in greece and registered, as thousands do every day, as a refugee. A second factor, the large Muslim Population in france, of which a small minority is sympathetic to the terrorist cause. Europe is looking at a situation where they have no internal control of borders, very anemic external control of borders. Millions of refugees flooding into europe. Unassimilated Muslim Populations. Europes in trouble. Reporter and that trouble, experts agree, is not going away. Intelligence agencies here in france and elsewhere are asking for more resources. It takes time, unfortunately. Reporter and as the threats grow, intelligence agencies are going to ask for more people and more money than they have now. Whether or not the lack of resources was the reason that the murders in paris went undetected is a big part of the investigation now. I think we have failed, of course. Its a matter of fact. Reporter a fact that citizens of this city and all of us are going to have to get used to, in the age of a global war with isis. This could be the terrible new normal. One of the most chilling aspects here that is being investigated is whether there was a real link to the migration crisis. There are still thousands a day leaving the middle east. Most going through turkey, heading their way to europe, trying to get here. Many of them, most of them, are absolutely refugees, people looking for a better life. But there are very few controls over that population movement. And officials in france and other countries in europe are wondering if isis managed to slip into that wave of suffering, that wave of migration. Richard engel for us this morning, thank you. As we mentioned in the u. S. , the nfl saying it will step up security at games today. In light of the paris stadium attack. The league is also urging fans not to bring bags with them. But if they must, to make sure the bags are small and clear. This comes as the fbi sends a small team to paris to help gather more intelligence. Sean joyce is a former Deputy Director at the fbi. He joins us this morning. Sean, good morning. Good morning, erica. Reporter sean, give us a sense, you have been in the situation rooms. You have been going through the intelligence in situations like this in the past. How alarmed is the Intelligence Community in france, in the united states, that somehow, something may have been missed here . I dont think so much its a question of them being alarmed or surprised. I think given the influx of immigrants, given that 5,000 to 6,000 people from europe have traveled from syria to iraq to fight for isis, as well as 200 to 300 americans that have travel there had. I dont think, as far as that goes, theres a big surprise. What i think they are trying to figure out right now, and as richard has mentioned, what is the extent of that network . Feverishly on right now. Is how do we make sure we identify everyone that was involved in these horrific attacks and make sure we capture them and find out if there are any further connections if there are any followup attacks. Reporter and, obviously, part of the concern there is this network is clearly expanding. And just in the last two weeks, the attacks that we have seen, the plane in egypt, bombings in beirut, now in france, with a lot of people at home in the u. S. Wondering, could the u. S. Be a target . Without question. I think we have seen an Inflection Point thats occurred here. We have to make sure, i think the u. S. Authorities, both the fbi and dhs, they have been working with all the Law Enforcement agencies to prepare for an attack like this. Its called the active shooter plan. They have been working with all of them, inclung ldie you mentioned, the sports venues. Making sure we are prepared for this. As you know, with the availability of and go ahead. Im sorry. Reporter i was going to say quickly, thats the one side. As richard brought up and weve heard all morning, frankly, all weekend here, there is this concern over whether or not one of the attackers may have made his way through greece from syria. How do you balance that concern for a Security Threat with this very real, very large humanitarian crisis . Well, i think youre right. It is a balance. What weve seen here is, i think, were going to hve to increase our vetting of these individuals. Were going to have to do a better job, to make sure that the folks with nefarious objectives arent going to sneak through and arent going to do Something Like what happened in paris. Former fbi Deputy Director sean joyce, appreciate your insight. Thank you. Now back to harry in new york. Thank you very much. The paris attacks at the g20 summit in turkey this morning. The killing of innocent people based on a twisted ideology is an attack not just on france, not just on turkey, but its an attack on the civilized world. The president referring there to twin suicide bombings in turkey last month. Nbcs ron allen is traveling with the president. Ron, this is supposed to be an economic summit. Ive got to imagine there are other things that are more that have risen to the top of the agenda. Reporter the terrorist attacks, the isis attacks, it dominates the summit now. President obama said the u. S. Will redouble their efforts to destroy isis and find a diplomatic solution to the syrian civil war. Turkey is the Perfect Place for these talks right now. Theyre in the front lines in the fight against terrorism. The u. S. Will be under pressure to reevaluate their strategy. In the days before the paris attacks and before arriving thought isis had been maintained a few weeks ago. He thought they were no longer gaining strength and thought this would be a multiyear effort to destroy the organization. The paris attacks created a new sense of urgency here at the summit and around the world. Because they revealed that isis has the ability to strike far beyond iraq and syria. The key to the u. S. Strategy has been to attack isis from the air. Thousands of air strikes, backing local forces on the ground. A program, a strategy, that the u. S. Has been trying to expand recently with mixed results. Also here, the humanitarian crisis. Hundreds of refugees pouring out of syria and into europe unlike any time since word war ii. Two very important and critical ys oda talks here in turkey. The question is what will the u. S. And allies do . How aggressively will they respond to the threat posed by isis . Ron allen with the president in turkey this morning. Thank you. The paris attacks changed the course of the Second Democratic president ial debate in iowa last night, with Hillary Clinton facing tough questions about isis from her rivals. Nbcs Kristen Welker is in ames, iowa, this morning, with more on that. Kristen, good morning. Reporter harry, good morning to you. The president ial candidates are waking up to a new reality this morning. The fight against isis is now the defining Foreign Policy issue of 2016. And that was on display here saturday night when the debate started with a robust discussion about combatting terrorism. Despite the somber backdrop of the attacks on paris. We ask you to join us in observing a moment of silence. Reporter frontrunner Hillary Clinton was on defense from the start about whether she and president obama, her former boss, underestimated isis. This cannot be an american fight, although American Leadership is essential. Reporter her rivals wasted no time pouncing. This actually is americas fight. Reporter and vermont senator Bernie Sanders slammed her for voting for the iraq war in 2002. I dont think a sensible person would disagree that the invasion of iraq led to the massive level of instability we are seeing right now. Reporter clintons opponents taking every chance to pile on. I have never heard a candidate, never, who has received huge amounts of money from oil, from coal, from wall street, all these Campaign Contributions will not influence me. The answer to impugn my integrity. Reporter clinton arguing saying her ties to wall street stem from representing the area during 9 11. We were attacked in Downtown Manhattan where wall street is. I did spent a whole lot of time and effort helping them rebuild. Reporter but it is paris changing the conversation on the campaign trail, including for republicans. Our prayers go to the people of france, but thats not enough. Action is required. Reporter many of them, again, accusing the president of being weak on isis. Barack obama does not wish to defend this country. He may have been tired of war, but our enemies are not tired of killing us. And theyre getting stronger. Reporter now many thought the tone of the debate would be more muted coming in the wake of paris, but the opposite was true. In fact, it got quite heated at moments. This morning, secretary clintons rivals in both parties are criticizing her for linking her ties to wall street to 9 11. Her campaign saying she was expressing her pride about having served new york as a u. S. Senator. Harry, back to you. Kristen welker in ames, iowa, this morning. Thank you very much. Chuck todd is the moderator of meet the press. We watched the debate last night with great interest. Did you see any policy shifts last night of significance, especially with the democrats saying, perhaps, maybe we really need to be more aggressive with isis . I think what you saw is a preview of what Hillary Clinton, if she is the democratic nominee, is going to face on the National Security front. Martin omalley last night, essentially, was making the argument that many republicans have been making against secretary clinton and the obama administration, and linking it he linked it, calling it the last 15 years on the strategy and what to do in the middle east, indicting the bush and the obama administrations. Where some of the younger republicans are doing that. So youre getting a preview of what a general election on the National Security front would look like. Chuck, in terms of the larger issue with this president ial campaign about a year away now, what about the republicans . Who youre looking at frontrunners, neither have Foreign Policy experience. I can tell you, everything having to do with donald trump and ben carson looks smaller today than it did 48 hours ago. Right . Thats number one. Number two, does it change the mindset of the republican primary voter who has been sort of looking for an outsider, not caring about the fact that they are lacking experience. Ill have jeb bush on the show, and hes making this case now more than ever. Not just him. Chris christie, john kasich, the folks who have more tangible experience in crisis. They are making their case. Will it work . Will the voters change their mindset . I think they could. You know what, predicting what the Republican Voters are going to do with donald trump has been a terrible place to be. Fools errand, indeed. Chuck, thanks very much. Youll have more on the paris terror attacks on a special edition of meet the press. And for the moment, i think well get a check of the weather. A little bit of rain, actually, a lot of rain and mountain snow out in the pacific northwest. Thats a look at the weather across the country. Heres a peek out your window. Good morning, a chilly start with temperatures in the 30s and 40s north ands we of town. But we are milder into the afternoon, a High Temperature of
