kim jong-il died two days ago. two full days went by before the a initial announcement came out. that's how tightly controlled the media is there. when it did arrive, his blinkered and brainwashed followers mourned him like the god they had been told he was. the grieving as you would imagine is intense for a leader they had been told first walked at three weeks of age. talked at two months and authored, not read but authored 1500 books while in college. those who are not overcome were simply dumb struck on receiving the news. like this gathering. they, like most north koreans not aware that eschar offed lobsters and had cognac while north koreans starved to death during the familiar inhis economic policies created. the mourners who made their way by the masses past a statue of kim il-sung did not know how -- how it is. when kim il-sung died, north koreans were told that a thousand white cranes tried to carry him off to heaven but were prevented from doing so by the pull of his devoted followers. people living then as now in one of two north korea's. the one they're allowed to see but keeping them honest we mostly see the other. sometimes they see more than they're supposed to and they wake up. they make a run for it over the border into china. out of the ground of a foreign embassy. some of them make it. this group did. others risk it all as a family in the clip we're about to show you. not everyone succeeds as you'll see in this clip from the documentary soul train. [ speaking foreign language ] scenes from china which shares a border with south korea. a shaky alliance as well. beijing is terrified at the prospect of millions of refugees flooding into southern china if north korea collapses. as we said, most north koreans don't really know their country is what it is. they don't know that it's that big space down there between china and south korea with the lights off at night because their power system barely work. a big black box. in more ways than one and more than ever tonight. but tonight we are taking you as far inside north korea as we possibly can with people who have seen it up close or dealt directly with kim jong-il, the dear departed leader. gary tuchman starts us off. >> with the beau font hair, platform shoes, over-sized glasses and trademark jumpsuit, kim jong-il looked every part the crazed tyrant. >> the appearance made it a little bit more difficult to treat him seriously, at least at first. >> he was certainly a man of eclectic and fine tastes. mr. kim was said to have a love of fine wines, cognac and foreign prostitutes. this despite an incredibly poor and often starving population. inside north korea it was all about kim. but state-run media created and nurturing a fully formed cult personality. he was the dear leader bravely flying fighter jet or writing operas or even shooting 11 holes in one in his first attempt at playing golf. he was also said to be a big fan of hollywood. his favorite movies, gone with the wind and any and all james bond movies. his father founded the totalitarian regime and died in 1994. he was considered god-like among his people. >> from the moment of his birth, he never could measure up to his father. he's had very, very difficult shoes to fill. >> bruce cummings studied korea for 40 years. he says the elder kim was ruthless. he was also charismatic and loved to be around people, unlike his son. kim jong-il's official biography says he was born in a log cabin in a sacred mount tan. when he was delivered, special stars shown in the sky. western scholars say it was more like siberia in a camp. he was a ruler who loved to make his people dance. a million of them all at once and all in step. you chase away fierce storms and give us faith, they sing, about their dear leader. charles armstrong said in an interview with cnn last year that despite his theatrics, he was a political giant. >> he's not a mad man. i think he's very smart man. he's very capable. he's well-trained in the art of politics. and he's very shrewd at how he operates. >> he was long at odds over the nuclear program in his country. having the capability to build a bomb was his greatest ambition. a goal he only recently realized had north korea tested the nuclear weapons in 2006. it put the world on notice and gave mr. kim the ultimate bargaining chip. the uncertainty of what comes next is all the more important. gary tuchman, cnn new york. joining us now are lisa and laura ling. she has a documentary which arms tomorrow night at account on the national gee ask channel. she snuck into north korea to make the documentary. her sister laura was taken by -- when they were filming along the north korea, chinese border. they were held, subjected to a show trial, convicted and sentenced to hard labor. after months of effort and efforts by former president clinton, they received a pardon and came home. they co-authored a book about the speerps called somewhere inside. one sister's captivity in north korea and the other's fight to bring her home. good to see you both. laura, i have to ask. kim jong-il's regime, they put you and your family -- so many of us watched while you were in captivity for five months. what were your thoughts when you heard about his death? >> it was very surreal. i got chills immediately. but i also thought about the north korean people, people who have been suffering under that regime for decades. i also thought about my guards, my interrogator, my interpreter. you know, these are people who are tasked with keeping me prisoner, but at the same time we did share, develop a relationship. i thought about what the future might hold for them. >> lisa, i imagine some of your thoughts, your initial thoughts were the same. it must have been a very emotional moment for you as well. >> it was. it was quite surprising for both of us. when president clinton met with kim jong-il when he negotiated the release of my sister and her colleague, he was very surprised by how coherent that the quote-unquote dear leader was at the time. he brought his physician with him. he noticed some paralysis on one side of his body. he his said his mental faculty were fully intact. >> he had had a stroke at some point in the recent past before that time that you saw him. laura -- >> reportedly. >> laura, you know firsthand the power and you saw the piece from gary tuchman that kim jong-il had over his people. what struck you about that while you were in captivity? >> sure. i was allowed to watch television and every piece of video on that screen practically shows images of kim jong-il as this other worldly figure and doing these wonderful things for his people. oftentimes, my guards would be moved to tears watching their dear leader and they talked about how much he was doing. they did mention that he was aging and that his health was failing. but they said that it was due to the fact that he was working so hard for his people. >> sanjay, you menged that i reported in north korea a couple of years before laura was held captive. i was astounded by the level of indock krin nation under which the people of north korea live. it's hard for us to imagine ha that could possibly be like. you mentioned all of the books that kim jong-il allegedly authored. when i was staying there, every single book on my bookshelf in the guest house was written by the dear leader or the great leader. when you're born into believing this is the only way of life, it's hard to even be curious about what the rest of the world is like. we've been hearing in the last couple of years, since laura was held captive, through an organization called liberty in north korea or link the refugees who have come out have gotten information because this black market exists and information is being smuggled in the way of cell phones at increasingly larger levels. >> it's absolutely fascinating. part of that documentary as well, if i remember, you were helping -- you were undercover and helping an eye surgeon perform these operations and i remember the documentary. i want to play a quick clip where this girl had been blind for years and gets her sight back and sees her father. take a listen. >>. [ speaking foreign language ] [ applause ] >> she is getting sight restoring operation. you said what shocked you the most was who she thanked after the operation. >> yeah. sanjay, as you know, cataracts can be so debilitating for people in the third world. they can live with total blindness for more than a decade. that was the case for so many of the people who the doctor was treating. once their sight was restored, it was quite amazing. they would have all of the people in a big room, there would be possibly a hundred people in the room and they'd remove the bandages from their eyes and instantly you would think that they would thank the doctors and their teams for restoring their sight. but in fact, they would immediately rush to the photo of the dear leader to thank him for restoring their vision. >> that was all -- i mean, this was of their own doing. they weren't being forced. this was of their own volition from all sounds of it. laura, let me ask you. kim jong-il's heir apparent, his son, he's young. the country is a young country, he's been educated outside of north korea. does this make you optimistic at all for the future of this country. >> well, i mean, i think that everyone right now, all we can do is speculate. there could be a window of opportunity. kim jong-il, there was 20 years for him to be groomed into a leader. kim jong-un has had less than two years. when you talk about this propaganda machine, kim jong-un has not existed for very long in that machine. it will be interesting to see what happens. >> we were trying to negotiate laura and euna's release. it was interesting because our sources were actually dealing with two entirely different factions inside of north korea. because it seemed that there was this schism between the members of the foreign ministry and the military. so if that is any indicator, it seems like it's just an extremely unpredictable time in that country right now. >> yeah. see if those bridges will be created. it's good to see you both. i'm glad you look so well. you look healthy. thanks for being with us. >> thank you. >> lisa and laura ling. thanks so much. let us know what you think about this. we're on facebook and google. follow me on twitter as well. sanjay gupta, cnn. i'll be tweeting throughout the show tonight. staying on topic, north korea's military might. it's nuclear arsenal. we hear approximate this. now there's a new finger on the button. we get a threat assessment from bill richardson. take you live to the most dangerous border on earth. the one separating north and south korea. later, when it comes to the republican primary, what goes up, must come down. another gop high flyer who is feeling gravity's pull. the latest on newt gingrich's slide in the polls. okay-y... okay??? i've been eating progresso and now my favorite old jeans...fit. okay is there a woman i can talk to? [ male announcer ] progresso. 40 soups 100 calories or less. you can put a force field on him and be invisible! [ child 2 ] i call first player. no. i already called it. [ dad ] nobody's playing anything until after we get our homework done. thank you. hello? test drive's not over yet. [ male announcer ] it's practically yours. [ louder ] hello? but we still need your signature. right now during sign then drive, it's never been easier to get the all-new passat, the 2012 motor trend car of the year, for practically just your signature. that's the power of german engineering. visit vwdealer.com. south korean armed forces on high alert tonight and not just because kim jong-il is dead. according to south korea's news agency the north did more missile testing just this morning, just before the death announcement came. and now the man supposedly in charge of north korea's massively armed forces, nuclear weapons included, is now apparently 20-year-old something kim jong-un. that's one concern. but so is everything that we don't know yet about north korea's military might. here's tom foreman. >> reporter: for a poor country north korea has long spent a disproportionate amount making its army look strong. what concerns military analysts most, however, is what we cannot see. first, the nuclear threat. under the obsessive prodding of kim jong-il, the secretive nation has been enriching uranium and amassing plutonium, possibly enough in hidden sites to make six or eight nuclear weapons or more. analysts are convinced north korean missiles can reach south korea, japan and maybe hawaii or alaska, although it's unclear whether they can carry nukes, but that may not matter. another credible theory is that north korean nukes could be hiding on merchant ships and sail to ports around the globe. second, the artillery threat. after the korean war, the north was heavily supported by russia. that stopped in the early '90s, but analysts say north korea has retained many pieces from that era and added more rockets and scud missiles although the fighter jets and ships would be destroyed quickly in open warfare, analysts think those ground weapons could pour explosives on to seoul 30 miles to the border producing tens of thousands of injuries and deaths in just the first hours. and third, there is the human threat. north korea has 400,000 infantry troops which military experts believe would either flood across the border into the south or dig in to repel any counterattack. more important, the north is believed to have 200,000 highly trained special forces soldiers who could infiltrate the south, wage guerrilla war and spread panic among civilians. the north is so unpredictable, even informed analysts admit all of these are just educated guesses, but they add, the world must be ready for the worst with north korea because that nation has been so unpredictable for so long and maybe even more so now. tom foreman, cnn, washington. >> and whatever may happen, the major flashpoint is just a short drive north from seoul on the demilitarized zone where north and south korean troops, not to mention american forces, all stand eyeball to eyeball. and paula hancocks is there tonight. paula, a lot of people have been following this history here. last year north korea sank a south korean warship killing dozens of sailors. these were believed to show that kim jong-un was a tough military commander. is there a fear now in south korea that further acts of aggression could take place to show the strength of this new korean leader? >> reporter: absolutely, sanjay. this is the crucial question. will he feel the need to have some kind of action of empowerment? this is what is believed to have happened last year. two very big attacks killing 50 south koreans and tensions then were as high as they have been since the 1950s korean war. so certainly that was believed to be a case of their showcasing an heir apparent a new successor and they wanted to show strength at the same time. now, the crucial question is will kim jong-un feel weak domestically. if he does, then we could see another attack in the future. this is something that the u.s. and the south koreans here are watching very closely. we're just a mile away from north korea. you can see it in the bad. you can see it in the background. this is something they're watching very closely. will he have all the old followers of his father's or will he bring in new loyal followers that would be loyal to him? it's really a very difficult question to answer. >> do you know just how ready south korea and the u.s., for that matter, is to respond to any provocation by north korea? >> reporter: the line is that they are constantly in a state of readiness. now, we know that the south korean military has actually increased its alert status. it is at one of the highest statuses at this point. that's a high alert. monitoring what the north koreans are doing very carefully. they're trying to see if there's any kind of troop movement, the south koreans and the u.s. but the u.s. has always said that they're here as a means of deterrent. rather than to respond in any way. this is what they've been working towards. u.s. soldiers here, an immense amount of military capability. there are missiles here to shoot down incoming missiles. they're ready but not trying to play it up in any way. >> paula hancocks, a short distance away from the demilitarized zone. please be safe out there. joining me former new mexico governor, energy ambassador bill richardson, he's logged plenty of miles and air miles dealing with kim jong-il. thanks governor for joining us. appreciate it. >> nice to be with you. >> thank you. you've said that what north korea's military does in the next day or two, 24 to 48 hours, is going to be decisive. is the danger, governor, more the unpredictability of the regime or the fear that the military becomes more belligerent in this region? >> well, the real fear, the real danger is the uncertainty. because what you have now is a totally new situation. kim jong-il is gone. there's an untested new leader designated by his father, but there's a cult of personality, a line of succession that has happened for many years in north korea. so the early indications are that the establishment has rallied behind kim jong-un, the son, the untested son. but the issue is will there be subsequent power struggles within the military, within the family that keeps kim jong-un with some degree of power? that is the uncertainty. now another point is that under kim jong-il, at least in the last 12 months, things were getting a little better. they weren't as belligerent. they were talking to south korea. they were talking to the united states on humanitarian aid. the north koreans said they were ready to re-engage in six-party talks on nuclear negotiations. again, you never can predict what they're going to do, sanjay. they're an isolated country. i've been there eight times, but i still can't predict what's going to happen next there. >> most people seem to know, ambassador richardson, about north korea, who even pay a little bit of attention, is its nuclear power. and they know some facts about its military. but correct me if i'm wrong, north korea doesn't seem to have the ability to launch a nuclear missile. is the bigger threat the potential to sell nuclear capability to u.s. enemy? >> well, that's the biggest danger that i think is overlooked, the fact that they have sold nuclear materials. they did it to syria. there's reports they did it with pakistan. they did it with burma. the sale of nuclear materials, enriched uranium for foreign exchange because they're the poorest nation on earth. that's the danger. and the fact that they have enough fuel possibly for six to eight nuclear weapons. that's the danger. the two missiles they sent out were maybe defective, but they did have some kind of a capability. so when you have a million men in arms, when you have all those missiles, then you have 25,000 american troops on the dmz, we have a treaty with our friend in south korea, you know, this is a tinderbox. you got to keep an eye on that situation. and the best way to do with them, i've always said, sanjay, is you engage them. you don't isolate them. you have a dialogue. you're skeptical. you verify everything that they say they're going to do. they usually don't keep their word. but isolate them to punish them, to ostracize them, to not have anyone talk to them, the chinese not talk to them, that's not the way to go. and i think the obama administration has been moving in the right direction to engage them. again, the last year has been a little positive movement. now, we're going to have to wait and see what the signals are from this new leader. >> a lot of people watching with waitful eyes. governor richardson, i really appreciate it. thanks very much
