Climb. We know that a number of those americans are being held hostage right now by hamas. I think that we all need to steal ourselves for the possibility the numbers will keep increasing, and that we may, in fact, find out that more americans are part of the hostage pool. Hamas is believed to have taken around 150 hostages, and the group is threatening to execute those hostages won by one. In retaliation for israeli air that hit dozens in their homes. The scale and the brutality of this crisis is without modern precedent. Today, israeli troops cleared the sites of hamas attacks near gaza, and the scope of this weekends violence became clear. Soldiers were seen in scores of bodies. 260 people killed, dancing at a Music Festival, families killed and safe rooms, or at bus stops, just going about their daily lives. Today, the u. S. And its highest serving diplomat to israel, secretary of state, Anthony Blinken in a show of support. President biden addressed publicly the war for a third time. And spoke to Prime Minister netanyahu for the fourth time since fighting began on saturday. Inside israel there are signs of political solidarity and today netanyahu and his top political rival benny gantz, formed a unity government and the Israeli Parliament and have something that wouldve been almost unthinkable just a week ago. But today, with his former political rivals set aside, netanyahu gave a speech vowing that every hamas member is a dead man. And that israel would crash and destroy hamas. To that end, last night, the first plane carrying american ammunition arrived in israel, against the backdrop of the Israeli Military. Amassing tanks, and troops near the coastal border ahead of unexpected Ground Invasion. Heres nbc news chief foreign correspondent, Richard Engel on this frontlines earlier today. Israels Defense Minister promises what is coming next will reshape gaza forever. We will reach all places, he says, hamas wanted to change the situation, it will change back 180 degrees. And they will regret this moment. As the Military Buildup picks up pace, israel has declared the entire area around gaza a military zone. Israel brought in enough tanks and armored for a full scale ground war, and is now mobilizing the more than 360, 000 reservists called up for national service. A new phase of this conflict is about to begin. And there will be many casualties. Today, hamas launched rockets past israels iron dome defense system, hitting the coastal israeli city of ashkelon. Meanwhile, airstrikes by the Israeli Military and gaza have displaced more than 260, 000 people. At least 1200 israelis have been killed since this weekends attacks, 2700 more injured. And in gaza, the death toll is at least 1100 people with more than 5300 injured. That number includes multiple medics and at least nine United Nations employees. But the toll of this war on civilians will almost certainly get work. Worse. Israel is blocking food, fuel, and water from entering gaza gazas densely populated region. And egypt has shut its border blocking the only Evacuation Route for civilians to escape gaza. That means that all 2 Million People that live in gaza are under siege. Which makes the task of fighting hamas, while avoiding civilian casualties nearly impossible. As David Ignatius writes in the Washington Post today, counterattacking through a maze of tall buildings, laced with hidden garrisons and booby trap passenger ways. For the ghastly attack, what defenses did they prepare . Hamas fighters dont wear uniforms, they hide and highrises alongside civilians, and now hostages. And hamas may have been planning for this stage of the attack for quite some time. On top of all of that, after shattering israels sense of security, hamas is declaring that it has one. And that it may very well continue to declare victory No Matter What comes to pass. From the New York Times today, it remains unclear whether the high cost to civilians will blow even when hamas attacks first, gazans ten to every war, no matter how many palestinians die, hamas will come after it and say, we are victorious. Joining me now is my friend, ali velshi, msnbcs Chief Correspondent Reporting live from tel aviv and israel. It is great to see you, i trust that you are safe and well. I know we have a delay, so let me get right to it. Just a staggering, deeply distressing scarring in some ways video that we are seeing of this attack, the aftermath, Israeli Security forces are Clearing Bodies and recovering the lost who died in the course of this Terrorist Attack, how is that Shaping Public Sentiment in this moment . We know that this was bad, the extent of the brutality ages seems to increase exponentially every day. It is incredible. How would you think after what we first saw on saturday that it would be worse on sunday, and on monday, and on tuesday, and on wednesday, but it actually is. In fact, for many of the israelis with whom i have spoken, it is not a matter of defeating hamas, it is a matter of flattening gaza. It is a matter of doing this in a way that it never comes back. I spoke to a man today who is one of these around gaza, who said i want them all gone. I want them to go to their friends in iran, and in egypt, this is our land. We want to be done that way. Ive spoken to other people who have served in the military. Theres military National Services in this country who have said a war, it Ground Invasion of gaza is going to be treacherous for Israeli Soldiers. However, the israeli population is united around this, the government is even, they have a unity government they form today between the right and the left. And the division is whether or not the effort should go into the ground offensive, which richard was talking about earlier. Or it should all go toward rescuing the hundred to 150 hostages that israel believes are being held by gaza. The families of this hostages when the hostage released to be priority number one, and that is the issue here. That they dont want this were to begin because they are quite convinced that once the Ground Invasion there is a war already, but once the Ground Invasion begins their loved ones will be Human Shields their loved ones might be killed. They might be killed and videotaped. Or filmed, and sent out as propaganda. So, that is why the division is. There is nobody who thinks that hamas should not be dealt with, or that there shouldnt be a war, it is about this hostage situation. You and i talked about it last night, and it hasnt evolved substantially. The only thing that has evolved here is that those troops, as richard said, are amassing in that military zone around the gaza border, and the situation in gaza has become much, much worse because of the lack of fuel and food there. The electricity is still 100 gone. Ali, i understand the desire on the part of the families of those taken hostage to prioritize the rescue of those captive men and women and families, children, but in terms of the broader israeli public, and of course i know that you have not spoken to every person in israel, but give me a sense of how well israelis recognize the sort of irreconcilable nature of Hostage Rescue any Ground Invasion to flatten gaza. I mean, have people i dont want to use the termed peace, but do they accept that one cannot go hand in hand with the other . Yeah, again, this is a country which, everyone serves in the military. They are all trained, they understand this. Since 1973, israel is not seen this. Its been worsened between, but it hasnt seen this degree of catastrophe. Nor has it seen what is likely to come if these troops that are amassed at the gazan border go in, so they are all conscious of it. They are all aware of it. It is a bit different than the Split Sentiment in america during the afghanistan and iraq wars were a lot of people didnt have a connection to a soldier or a person in american who is dying over there. That is not the case here. Everybody is in this. One way or the other. I mean, you choose to live in israel or come to israel, knowing full well that you will serve in the military. So that doesnt seem to be the issue, no one is under the makings conception that if israel goes into gaza and does that street battle, and in between those apartment buildings, and those perhaps booby trapped buildings, that many, many Israeli Soldiers would die. And in fact, as you know, you put the death total of civilians, and at this point, people realize that if there is a ground offensive, the death toll but soldiers will be very high. That is something that Israelis Internalize when they have soldiers that are killed. Because it feels like a national effort. Yes, they know, if this ground war ensues, a lot of at least many Israeli Soldiers will die and it. We are still prepared to undertake it. Just incalculable loss all around. Forwards and backwards. Ali velshi, great reporting, please stay safe, my friend. Please come back and talk to us more about what you are seeing and hearing. Thank you. Joining me now is ayman mohyeldin, that we have ayman on msnbc. And he has extensively covered and ayman mohyeldin, its great to talk to you. I wanted to since this war began. The idea of defeating hamas, it seems that once quite obvious and yet unbelievably elusive. Because at this point, hamas seems to be as much of an organization that citizen ideology. And one that will, apparently, if you believe the New York Times claim victory No Matter What. Do you think it is a goal that can really realistically be approached . I think if the goal is to destroy the organization itself, there are certainly tactical ways that israel has tried to do that in the past, and history is the best lesson here. Because if you look at what israel has done repeatedly since 2016, and before that, it has gone after hamas very aggressively and we should be very clear about that because Israeli Military officials, certainly retired one, have been clear about that. They killed the spiritual leader of hamas, theyve killed political figures within hamas, theyve killed senior Military Commanders within hamass military. Theyve killed financiers that tried to raise money for hamas. Bomb makers. Drone makers. Theyve gone after all of them. And, theyve gone and inside into gaza, in 2014, 2008 operation, this would be the fifth war in the span of 15 years in which israel has gone into gaza and try to destroy it using air power, and everything it has. And every time that hamas has shown itself to be resilient and in some cases, has even come back, bounced back with stronger capabilities as we have just seen, now this is the deadliest, to your, point i think that you are right. Theres an argument me that if you go in this time and we occupy gaza, you could perhaps destroy the structure of the organization. But if you studied palestinian history and looked at the rise of militant groups over the years, you would see an evolution from the 60s, 70s, 80s, 90s, in which 11 organization is defeated or destroyed, another one involves in this place. And i think that that is the fundamental issue here. Because hamas is an ideology that builds itself on a Central Tenet of claiming to be a Resistance Movement to israels occupation, there is always going to be an ability to recruit from palestinians and get support from countries like iran, who buy into that and variable to then take the next level or the next organization, or generation of fighters. Regardless of whether they call themselves hamas or Something Else . You are one of the very few people that i know, that i think are on tv, that has actually reside in gaza. You understand the architecture of that region. There is this sort of ideological battle against hamas, there is the tactical battle against hamas, and it seems, i wonder if you could explain a bit more about what Israeli Security forces, Defense Forces are facing, as they try and route out hamas fighters from such a densely populated area. Yeah, theres two layers to the challenge, and i was boost as a correspondent in gaza from 2018 2010, i covered operation cast, lead and then subsequently would go back for various operations and wars that happened there. And in the 2008 war, israels challenge was to essentially cut gaza in half to try to separate the northern part of gaza, which has gaza city, and very densely populated from the southern part of gaza, which was more farmland, but also had big refugee camps, and also very densely Populated Areas. So addition to the ability of moving around in these densely Populated Areas with tanks, armored personnel carriers, air power, over the last several years, hamas has been able to develop a very complicated and Sophisticated Network of tunnels underground. And in that capacity, it was able to penetrate israel, cross borders, Lee Booby Traps for them as it moved, and certainly in the northern part of gaza. Like the refugee camps, and it made it very difficult for the israelis to, not only take gaza, but take and move within gaza. So in an operation in 2008, 2009, it is successfully controlled the entire territory. They divided the territory and half of their tanks and armored personnel carriers. But once they were in there, they stayed outside of the urban centers. So it was easy for hamas at that time to withstand the pressure, obviously if they go in this time, they are not going to repeat that. They want to go into the urban areas to really wheat hummus out. But that is where hamas wants the fight to be tactically, and that is where the danger is going to lie for both Israeli Soldiers, and the civilians who have not gone out. And hostages. Of course. And it is important to remember one thing about the palestinians who may want to leave, and who may not want to leave. And i heard an earlier guest on our show say this, which is that 60 of the palestinians who live in gaza are descendants of two generations of palestinians who have either been expelled from their homes or removed in 1967. So there is those kind of generational trauma that exist among palestinians about not leaving their homes after fear of what comes next. So as a result, palestinians who may want to leave, they may have a large part in this, but other palestinians will say this is our homeland and we know what happens in 67, we know is what happened to us in 1948 when we left our homeland as refugees, and we were never allowed to return. Let me ask you one more question theres a lot of talk about whether or not egypt will help open up a humanitarian corridor for those gazans who wish to leave, it seems like, given the lack of resources, the electricity, the water, the bombing hospitals and so forth, theres probably still is sizeable population that very much wants to get out . Absolutely. We saw that previously. Are you at all optimistic that egypt will be convinced to open up humanitarian corridor here . Im not convinced. They havent done it in previous wars. And the argument that egypt provides, and i know that weve been hearing from american officials that they are working on that, and that it would be very interesting to see what if anything changes the calculation of the Egyptian Government. Previously, egypt has taken the position that if they opened the corridor, for palestinians to leave, that they would become responsible for the refugees. And they have learned from neighboring countries what has happened one other countries have taken refugees that are abandoned by the international community. Egypts position has always been we will not absolve israels responsibility for the people of gaza by accepting them into egypt, and ultimately being the only party responsible for that. There are no guarantees that of the palestinians weve got to come to egypt, they will be allowed to return to their homes, as we have learned from history. And as a result of that, egypt has taken a position that the only way to deal with this crisis is through a multi party agreement. So, ive been watching the language of american officials. Jake sullivan, admiral kirby, even the secretary of state, Anthony Blinken, today before you head towards the region. Its very clear, we are trying to work on something. What that looks like . I think it will be very telling. But i dont see the Egyptian Government now just simply unilaterally changing a fundamental principle that it has held onto in four previous wars. They may try to offer relief, they may offer certain amounts of people to come through, but theyve never open the border to simply allow hundreds of thousands, if not 1 Million People just to come and reside into the sinai peninsula. Ayman mohyeldin, you are a wealth of information and such valuable perspective in this moment. Thank you, my friend, for joining me on set tonight. When we return we are going to speak with one of the survivors of the Terrorist Attack on a
