>> announcer: this is cnn breaking news. good evening. this is "the source." i'm kaitlan collins. we begin with two breaking stories. right now, we are three hours away from a fragile truce between israel and hamas, potentially coming to an end. right now, there's a real possibility that it may not be extended. first tonight, we start with this, which we have confirmed moments ago. former u.s. secretary of state henry kissinger has died. that's according to his consulting firm kissinger associates. he was 100 years owed. he passed away at his home today in connecticut. kissinger was secretary of state under presidents nixon and ford. the only person to serve as the national security advisor and secretary of state at the same time. more now on his legacy. >> i know all of you will want to hear from the new secretary of state. >> henry kissinger never really needed an introduction on the world state again. the most famous statesman of the last half of the 20th century. celebrated and controversial. as richard nixon's national security advisor, and secretary of state, the diplomat wielded ee enormous power and influence. he went to china on a secret mission to explore a historic opening of u.s. relations with communist china. >> whenever went would be alone in beijing with no communication. therefore, if he didn't know nixon's mind, he might do foolish things. >> initially, there were fears that the ping-pong exchange match would affect the political gabit. >> something happens in diplomacy which transcends the drafting of cables. >> the vietnamese gained territory. nixon and an undiplomatic kissinger thought more bombing of the north would help. >> i would recommend we start bombing the bejesus out of them. >> kissinger approved secret bombings in cambodia without congressional approval. he would say, sometimes statesmen have to choose between evils. kissinger and his vietnamese counterpart were awarded the nobel peace prize for this role in negotiatiing a cease-fire. >> i have never bdealt with a group of people as treacherous as the north vietnamese. >> he said trouble on the homefront hurt chances to win. >> we were divided and because we were too uncertain about what we wanted. >> kissinger's support for a coup in chile and pro-u.s. military strongmen in other parts of the world drew criticism. kissinger's legacy would be contested decades later when he testified in congress at the age of 91. kissinger grew up in germany with war clouds swirling. his family fled when he was 15. >> half of the people i went to school with and about 13 members of my own family died in concentration camps. >> a jewish secretary of state who would later listen to his president criticize american jewish leaders. >> it's about time the jews in american realize june 2nd. >> i heard anti-semitic comments when some jewish group would attack him for something he had done. >> in the middle east, perhedip setting the stage for future peace accords. when nixon resigned as president, kissinger stayed on as ford's secretary of state. his opinion still widely sought after by governments and businesses after leaving public office. >> you want to leave your country better off than you found it. there's nothing in private life you can do that as interesting and fulfilling. >> there was one job kissinger said he never got to do in his life. a sports announcer. >> derek who? >> however, the diplomat did star in some of history's biggest games. >> for more now on henry kissinger's legacy, for those just tuning in, we have confirmed henry kissinger died at the age of 100. i want to bring in tim noftali. thank you for hopping on the phone for this breakinnews. as we start here and as we look at this moment, can you put his long legacy in shaping foreign affairs into perspective? >> well, henry kissinger was a towering figure in u.s. foreign relations. both admired and hated. he was the most consequential foreign policymaker of the superpower era. he didn't do it alone. he and richard nixon were a powerful team. kissinger provided a genius for multi-level -- playing multi-level diplomatic chess, which allowed the u.s. government and the nixon administration to implement nixon's policies, the most famous of which, of course, was the opening to china. henry kissinger began his career as a professor, an academic at harvard, thinking about u.s. foreign policy in particular, thinking about nuclear weapons and their utility in the struggle with the soviet union. he sought power himself. he initially was an advisor to kennedy administration. when he didn't feel he was listened to, he offered himself to nelson rockefeller, who was a republican governor of new york. he later provided some assistance to the johnson administration, but found his home ultimately as the implementer and chief advisor to richard nixon. it's the nixon/kissinger team that would be the most consequential of any team in u.s. foreign policy until the end of the cold war. after he left washington, he remained significant, not only as a conduit between american foreign policy leaders and leaders that kissinger had known, but kissinger was the man to see if you wanted to meet the latest american president. kissinger is not only significant in shaping the policies of one presidency as both a national security advi advisor, then a secretary of state, then both, but he would become an important figure for those trying to understand u.s. foreign policy for decades. indeed, after his 100th birthday, henry kissinger was an honored guest in china. for the chinese, kissinger was a symbol of a relationship with the united states that practically doesn't really exist anymore. kissinger was extremely controversial because he and nixon had undertaken controversial policies. the christmas bombing and the overturning of the government in chile. >> what i'm thinking about, being here on the ground in tel aviv as this news is breaking, is his role here in the middle east. in the efforts he undertook to forge a peace, after the 1973 war, and what that looked like. can you talk about that influence that he had, particularly on this region in that moment? >> he had enormous influence. first of all, because the president of the united states was largely incapacitated during the war. nixon was dealing with the acceleration of the watergate scandal and the start of the impeachment inquiry. for all intents and purposes, henry kissinger was directing u.s. foreign policy during the crisis. after the crisis, kissinger, with nixon's approval, of course, but kissinger undertook the most complicated set of negotiations to establish a laughing cease-fire on both the northern border with syria and the border with egypt in the south. that took enormous effort and was a real diplomatic achievement on the part of henry kissinger. he is remembered as a very significant figure in the history of the middle east. let's not also forget that he undertook very strenuous negotiations with the north vietnamese which led to the american dimension of the vietnam civil war. henry kissinger was the most significant influence on the cold war, without exception. >> tim, i want you to stand by. i want you to continue putting this legacy in perspective. we also have susan glasser. just look at putting his legacy in perspective with how it is viewed now, this is someone who was revered and also reviled. secretary of state, the only person to serve as white house national security advisor and secretary of state. how do you put his legacy in perspective to how people view it now in 2023? >> well, thank you so much. i would agree with you that he was a divisive figure in life as he will be in death. for many liberals, for multiple generations, kissinger is what they would say, the evidence of his war crimes in advising nixon and the secret bombing of cambodia, those things loom large. equally so were the diplomatic achievements you were just speaking about. his enormous foreign policy vision and big brain shaped the later decades of the cold war in a way that we are still dealing with the legacy of it. the middle east, he basically created the notion of shuttle diplomacy and the peace process. he understood in many ways it was the process itself that could bring a form of stability to the middle east. his opening with nixon to china is something that has continued to shape the contours of u.s. policy toward china. you mentioned he just went to china not that long ago after turning 100 years old and was continually a voice for engagement between great powers, including the united states, russia, and china, despite the tensions of recent years. >> yeah. that shuttle diplomacy helping stabilize relations between israel and its arab neighbors. the other thing i think, susan, that sticks out is obviously, his legacy and his influence continued to endure long after he was not formally in office. the bush administration consulted him. he spent a lot of time at the white house informally giving almost every president advice since then. >> well, that's exactly right. he was -- continued to be advising. by the way, democrats -- many democrats as well as republicans were very interested, at least privately, to hear from him, despite the view of many about sort of his public facing. he was speaking with hillary clinton. he had the current secretary of state, tony blinken, i believe, attended his 100th birthday party celebration in new york earlier this year. henry kissinger in his late 90 s was eager to be on the inside. he spoke with donald trump when he was president. kissinger was someone for whom access was something he never gave up on. he always wanted to be in the thick of things. >> susan, stand by. i want to bring in the man who wrote the book on kissinger. thank you, ambassador, for being here. what do you make of the fact that this is happening in this moment, thinking about his relationship he had w-- his influence after the war. what's your reaction after learning of his death? >> in 1973 when henry kissinger surprised by the war intervened actively and managed to negotiate a cease-fire after 16 days of fighting and began a process of negotiating territory for peace which laid the foundation not only for the american-led peace process, but essentially for american domination in the middle east, the exclusion of the soviet union from the area. he negotiated three agreements, two between israel and egypt, one between israel and took egypt out of the equation. he had the disengagement agreement. he said to me, he was not disappointed that 50 years later, the agreement held. even though his statesmanship in terms of the soviet union and arms control and china as well as his other controversial involvement in laos and chile and other places. the place where i think he made the most good was in the middle east where he laid foundations for peace between israel and the arab states. he never managed to deal with the palestinian problem. they were a minor nuisance in those days. a terrorist organization, not a state. kissinger only dealt with states. he didn't have time for non-state actors. i think there's a lot we can learn from the way that he dealt successfully with the arabs and israelis, for the way that the united states can deal with the horrendous conflict between the israelis and palestinians we face today. >> what are those lessons do you think? what would he think those lessons are for the moment that we are in right now? >> the first -- you saw it in ukraine as well -- is that you should always try to end the fighting as quickly as possible. that's controversial in this case because of the nature of hamas. but that was his first instinct. second was to try to get a negotiation going. but to be very careful about being too ambitious. i think his advice to joe biden today would be, it's fine to talk about a two-state solution, but it's a big mistake to try to achieve it in these circumstances. we cannot get there from here. his approach was incremental. he was a republican, he was conservative in his approach. deeply skeptical of the pursuit of peace, because he feared that it would lead to war. he called it the paradox of peace. instead, he felt that it was important to try to get the sides to reduce their animosity towards each other, to find ways to live with each other. and then over time, eventually, it might be possible to reach a final peace agreement in the conflict agreement. in the meantime, what was important was to ensure a balance of power in favor of those who sought to maintain order, stability, and give time for everyone to come to terms with each other. for that to work, there had to be what he referred to as a modicum of justice for all sides to feel that they were getting something out of this process of coming to terms with each other. if you think about it today, israelis and palestinians are so far apart, so meired in conflic. try to end the conflict and begin small steps towards reconciliation with the ultimate goal of a two-state solution. but a very real understanding that it's going to take a long time to get there from here. >> certainly. it's quite a legacy to reflect on, especially in this moment. thank you for that. of course, we are following this news closely. former secretary of state who shaped world affairs in the region we are in right now has now died. henry kissinger, at age 100. we will have more on that ahead. our major breaking story on the ground in tel aviv, we are less than three hours away from the truce deal between israel and hamas expiring. we are waiting to see what is happening. that's in a moment. we are following our other major story. negotiations are still ongoing to see what is going to happen with this temporary truce between israel and hamas. it's set to expire less than three hours from now. right now, no extension has been announced. what we were told by sources is that israeli officials were waiting for hamas to hand over a list of ten names, women and children, of who were going to be released on the next day to have another pause in the fighting. so far, they have not gotten that list, not one they would accept. there are questions of whether or not that's going to be resolved before the truce is set to expire at midnight eastern, 7:00 a.m. here local. that leaves open the possibility that fighting could resume in just hours from now. we are covering this breaking story from every angle. we have expert analysis here on the ground in tel aviv. new reporting in washington and hearing from the white house, what they are saying. i want to start with an israeli journalist. we have been talking to you every night about this. what is your sense of how much on the brink this deal really is? >> hamas can supply israel with a better list than it did in the last 24 hours. the problem is this, there is a category of women and children that hamas is committed to. they have supplied the list that israel is saying is not satisfactory. that's a reason israel has rejected this. there was a cabinet meeting. the decision was to tell hamas, we're not accepting this list. unless you supply us with a new list by 7:00 a.m., the truce is over. fighting will resume. >> basically, the list that hamas gave to israel tonight was not sufficient? it didn't have only women and children on it, even though there are women and children to be released? >> that's the reason. whether or not israel will resume immediately at 7:00 a.m. the fighting or not, it's a question. but both sides are basically playing chicken here with each other. there is a very distinct possibility we will see this whole thing collapse. right now, the negotiators are saying both sides have an interest to reach some sort of an agreement until the morning. >> on that front, mj lee at the white house, secretary of state blinken just arrived here a few hours ago. he is on the ground in tel aviv right now. how closely is the white house watching to see what could be happening in less than three hours from now? >> it's a big, big priority for the white house right now to see this truce extended. it's why we saw bill burns, the cia director, in doha yesterday, why tony blinken was in israel today. the longer the pause, u.s. officials say, the more hostages that can come out, the more surge in humanitarian aid we can see going into gaza. earlier today, as you remember, one american citizen did end up being released from hamas captivity. we don't have any word on the second u.s. woman that is expected to be -- believed to be held hostage. not account for the seven others, unaccounted for americans that are supposed to be -- believed to be held in gaza as well. what we are seeing tonight, i think, is just how much this truce has been a day by day sort of ordeal where all of the parties involved basically have to wait for hamas to produce a list. it's worth noting that in previous nights, we have seen different problems, different issues come up and they did eventually end up getting resolved. of course, there is so much focus on this right now because there's an actual deadline. once that is passed, rear has made clear, the fighting is going to continue. >> yeah. that's the major question here. for what could be next militarily, colonel, you have been watching this as israel is now paused. it's very quiet here in tel aviv. previously, you could hear what was happening in gaza, the constant bombardment and the ground invasion. the troops are still on the ground. how quickly could the fighting resume if this truce doesn't get extended? >> it could resume fairly quickly, actually, because the israelis are in significant positions in northern and central gaza. hamas has been active. they have been caught in various places trying to place ieds and there have been a couple skirmishes with israeli forces, even in spite of the pause in the fighting. these hostilities could resume quickly. i'm certain the israelis have plans they could execute at the drop of a hat. that's, of course, something that could spell danger to the whole process of trying to extend this truce. >> colonel, we will watch closely. mj lee at the white house, thank you all for this. we are watching so closely to see what does happen here and whether or not this temporary truce that has been in place for several days now is now about to come to an end. the youngest hostage taken we know has become a symbol of the cruelty of this entire ongoing ordeal. the world has been waiting for the release. tonight, hamas is claiming without any evidence, i should note, that he has been killed along with his 4-year-old brother and their mother who were taken hostage on october 7th. we are learning more from israel tonight on how they are assessing that claim. we will speak to a member of the bibas family right after thihis. perhaps one of the most glaring parts of today's list of hostages who are released is who was not on that list. the youtyoungest hostage. hamas is claiming, without providing evidence, that he and his 4-year-old brother and their mother were killed in an israeli air strike. it's a claim that israel says it is assessing. there's no word on their father who was also taken hostage, we believe, as well that day on october 7th. joining me now is the great uncle of the children. thank you for being here. we have been speaking with family members in the last several days. it's hard to know where to start with this conversation. i know israeli officials have been in touch with the family. what are you hearing from them? >> first of all, thank you for having me. what i'm hearing from israel is the same news that you are hearing everywhere else. what we know that on october 7, right after 8:00 a.m., famous videos show the terrifying image of sherri holding her babies, that have become so popular. she's holding them. she's arrive, th -- she's alive. she's being pushed by te
