u.s. defense secretary james mattis responding earlier today to north korea's claims of firing off another icbm. >> kim jong-un should take heed of the u.n. security council's unanimous voice -- they remain unanimous in their commitment to the denuclearization of the korean peninsula. because we are not looking to the total annihilation of a country, namely north korea. but as i said, we have many options to do so. >> and then this just in to msnbc. we are hearing from the young hot news agency that south korea is holding ballistic missile drills now in response to the

north korea test. also word that president trump has spoken with japanese prime minister shinzo abe about the international community stepping up its response. it's all while an emergency meeting of the u.n. security council called for tomorrow morning, 10:00 a.m. eastern, following pyongyang's actions. let's bring in nbc's garrett haake who joins us once again from the white house. latest we're getting, is this missile test -- there isn't a lot of detail -- from the young hot news agency and what south korea is doing. >> reporter: yeah. south korea and japan have been driving the bus on the sort of kinetic response to this north korean nuclear test overnight. we've been hearing more from south korea and japan frankly about their responses to this action than we have been from the white house today. it is important to remember kind of how we came into this event that started overnight. it was just last week that the president was saying all options were going to be on the table

for north korea's most recent, prior to this, aggressive action. the firing of that missile over the japanese islands. and so that sort of had the table set coming in to today. we know the president has spoken with the japanese prime minister today. we know that the national security advisor, h.r. mcmaster, has spoken with his south korean counterpart today, and we've seen this sort of ratcheting up of the language and what appears to be the likelihood of some kind of military response throughout the day from the president, including his tweets this morning saying things like that the south korean response has been "appeasement" and it hasn't been working, not thafac that he held this meeting at the white house today primarily focused around military options. secretary mattis said the president wanted to know all the options that were on the able, he was standing next to the joi chairman of the joint chiefs. there was also the dire warning from north korea to james mattis

today. >> any threat to the united states and its territories including guam or our allies will be met with a massive military response, a response both effective and overwhelming. >> mattis also told the north koreans in that statement, essentially, that they are not -- u.s. response here is not to pursue regime change. he left them an off-ramp, saying we're not trying to wipe out this country, we're trying to stop the denuclearization of the korean peninsula. so a lot of tough words from mattis. and of course, from the president today, saying only l "we'll see" when asked if he would attack north korea. indeed every option on the table and it appears the president is reviewing quite closely those military options tonight. >> a busy sunday afternoon and evening there at the white house on a sunday, as i was mentioning. nbc's garrett haake covering it all for us. thanks very much. now over to the korean peninsula where ron allen is in seoul, south korea. ron who was covering this all overnight with us here on msnbc.

ron, what is the latest? there's this discussion -- at least the report from the news agency about a south korean ballistic missile drill. >> reporter: it is a military exercise, a drill, a training, and it is a simulated attack on north korea's nuclear facilities. that's the message that the south korea government is sending with this exercise. and this is apparently one of the military options that is being pursued. it is similar to a drill, an exercise that happened a couple of days ago involving the united states, japan and south korea where they flew mock bombing exercises that were said to be an exercise to take out an enemy regime. so there's been that happening over the past couple of days now, and this exer scise that's happening now that we're just hearing about is in direct response to the north korean missile test. so those are the military things

happening and all in the category of what you would call deterrence. there are very few people, experts and analysts in this part of the world, or anywhere, who think that there is an aggressive, an offensive military strike option that the united states or south korea has against north korea that would not be countered by a deadly cataclysmic response by the north koreans. not in terms of a nuclear response, but in terms of a conventional weapons response. remember the north has one of the largest standing armies anywhere in the world. the border that's some 50 miles from here is heavily fortified with artillery pieces that can reach into south korea and there are literally tens of millions of people in harm's way. that's why most analysts talk about the fact that the so-called military options are really not realistic options unless -- and every military leader in the world is well aware of the consequences of this. that's why there have been a lot of calls today for restraint. there have been a lot of calls

from around the world for dialogue and discussions to try and end this crisis and condemnation for the north koreans, of course, because of what they did. richard? >> nbc's ron allen live for us there in seoul, south korea, not too far there from the border with north korea. thank you so much, ron, for your reporting there. let's bring in steve clements, richard painter, robert trayham, gloria difrancesco. all four, thanks. we'll start with you, steve. nato, very clear in saying this is not good. they have absolutely rejected this report of a test and it seems like a test has happened. that much most would agree with. in addition to that, as we look at some of the responses that may come from north america specifically, the united states is what i am alluding to, this is a very complex mix of foreign

affairs that they're trying to put together in response to north korea. >> richard, this has been a complex situation for many presidencies. it was the one item that president obama shared with incoming president trump as being the nightmare he was going to have to wrestle through. and absolutely, north korea's technical sophistication and the ability to both miniaturize dangerous warheads and put them on intercontinental ballistic missiles is in part driving some of this. but the piece that just perplexes me, we are talking all throughout tv as jim mattis did today, about potential total annihilation perhaps of north korea, of war scenarios. i really like to know, where is the state department? where is diplomacy? where is the effort to tie in russia, china, south korea, japan, europe, the united nations, in a joint effort to do what we did with iran, to cripple it in order to create such a point and give it some light at the end of a tunnel that it was pushed in a direction that would be

constructive. that was the iran deal model that obama used. there are differences with north korea, as i interviewed some of barack obama's lead negotiators and particularly wendy sherman, she said even with a democrat we would get to a kind of war-like verge of war situation before north korea moved. but donald trump has not invested anything at all in the diplomatic process of trying to unite the frustration of the neighborhood against north korea. it's all one-on-one and it's just slipshot. >> roberttraynam, as we look at the potential response coming from the united states, we heard the reporting, most would agree that a military response is not good and it will not happen because of the potential reaction that is a domino effect there in the asian theater. nevertheless, when we were speaking with barry mccaffrey

little bit earlier, he was pretty open in that maybe a military response would be one of the scenarios that they're considering a little more seriously now. >> yeah. general mccaffrey was very direct and he said, from what understood it to be, is military option is probably the only option right now. but let me speak to a larger point that i think steve was alluding to. here you have a president that appears at least in public not to have the diplomacy experience and/or the gravitas, and/or, even quite frankly, just through deductive reasoning, trying to think this through like a game of chess. you also have rex tillerson, our secretary of state, who's fairly quiet on this issue. the question is becomes will cooler heads prevail. the question becomes whether allies, perhaps angela merkel or perhaps prime minister may will gret to t get to the president and say, look, mr. president, have you thought this through? perhaps maybe you should dial down the rhetoric and perhaps behind the scenes let the staff kind of do more of the work

here. what you are doing here is escalating this because you are not dealing with a rational person, meaning kim jong-un. the question is whether the president will be able to have some restraint and dial back the rhetoric, or -- or -- perhaps is he crazy like a fox. perhaps he is much more sophisticated than we think and maybe he knows exactly what he's doing when it comes to ratcheting up the rhetoric. i don't think so, but i want to give him the benefit of the doubt. >> president trump warned that the united states military is locked and loaded. threatening fire and fury. his words there. richard, what are the risks of drawing these lines in the sand and north korea keeps on crossing them? >> well, i think if we do it unilaterally, we're going to be in a lot of trouble here. this development is one more nail in the coffin of the america-first movement and the economic nationalism of the alt-right, steve bannon, and the others. we are realizing, yet again,

that the united states has to work with other countries in the world to solve problems, including the nuclearization of the korean peninsula. china has a lot of loeverage ovr north korea. china needs to understand if they are work with us, we will work with them. we're not there to launch a trade war with china. we want to work with them and with south korea and the other countries in the region to deal with the north korean regime. but if we per sue the america-first route, we talk about trade wars with china, with south korea. we alienate people all over the world. that's what's been going on since january. and that needs to stop. i think that the white house is realizing that the america-first movement has been a disaster. that we need to engage with the rest of the world. we need more friends in the world. and that's not where we are right now. china, once again, critically important country. we need to be on the phone with klein and work with through with

them so they understand and work with us. they understand the importance of bringing north korea to heel. >> congressman, an important part of that discussion and potentially any treaties or understandings that may result or grievance that may result from this white house working with other leaders of other countries. victoria, if it is congress, then there's democrats. and if there's democrats, they have been quite critical of the again fire and fury sorts of comments coming from the white house. would they support though now the words that came from the secretary of defense that came out just about two and a half ours ago? >> right. so ultimately here when we get to an issue as grave as this, as the potential for a conflict with north korea, you see the lines between democrat and republican start to ease away. we've seen this historically. the question here is, what is the method that the president is going to use to engage with his colleagues in congress. remember that the president has had problems with his colleagues

in congress, with those folks in congress, not just among the democrats, but his own party. so here we're going to have to see a strategy by the president, first how do i engage with congress, and second, how do i bring over maybe those democrats that are a little less likely to lean over to where i am in the fire and fury. so it is going to be a very delicate balance. i want to highlight what the other panelists said, bringing in the state department at the same time. so it is a two-pronged approach, bringing in the legislative branch and also bringing the state department in to close call with that conversation. >> steve, is this a bilateral solution or bilateral move, whatever is next, that the united states does need to move alone? >> i don't think -- i don't think united states can move effectively alone, but i think that's the way donald trump sees the situation, regrettably. and i think that he's been trying to sort of, here and there, give china or south korea

the whole load and say, china is embarrassed by this, or china's trying but not getting this done. and so he's set up the circumstances where they're failing and we're somehow going to proceed. but as i said earlier today, i think what's happened right now is that the differences we see within the administration -- you have jim mattis just the other day talking about there were no end of diplomatic options that still could yet be tried. and that was very different than what the president said. there are divisions within the white house, and i think north korea's testing this white house to see how far it can get moving its agenda forward. not as a sign that it recognizes american strength in this but it senses american weakness and it senses that america's allies in the region don't trust the united states. that is a really huge problem. so as we begin to consider kinetic options of taking on north korea -- and look, we're not talking -- jim mattis is talking about retaliatory strikes. what donald trump is

considering, from what he's telegraphing, is a first strike. i think those are very, very different kinds of things. and that could really punctuate perhaps really the end of american influence and power in asia. not the broadening and echo effects of a broader power in the region. >> a major realignment. steve clemons, thank you so much. the rest of you will stay with us for a later segment. thank you so much. president trump muls a major decision on what to do about daca. many, including those in his own party, are urging him to keep the dreamer program into place. up next, we'll talk to a young dreamer who will be directly affected by the president's decision.

when i walked through a snowstorm for a cigarette, that's when i knew i had to quit. for real this time. that's why i'm using nicorette. only nicorette gum has patented dual-coated technology for great taste, plus intense craving relief. every great why needs a great how. ♪ but their nutritional needs (vremain instinctual.d, that's why there's purina one true instinct. nutrient-dense, protein-rich, real meat number one. this is a different breed of nutrition. purina one, true instinct.

a million young lives hang by a thread. or more. on tuesday, president trump may scrap daca, the obama era program allowing so-called dreamers to live and work in the united states shielding them from deportation. ending it would result in more than 1,000 people losing their

daca status, and therefore losing their jobs. there is every day. people like jimina when she came to the united states when she was 9 years old. she also wanted to join the military, but even a 4.0 gpa not enough for her because of her undocumented status. she joins us now live from houston, along with us, back, victoria defranchesco from the university of texas. as we look at tuesday, right? in two days we expect the president to reveal his decision on whether to rescind the daca status for 800,000. but, in addition to that, potentially it's been estimated there are another 1 million who could be eligible for daca status. give us a sense of what that might mean. >> right. so, working a lot with communities here in houston, we do go to local schools in hiz

and we alwado have thoudsands o students currently who would be affected by the decision that the president makes. another thing that we're facing right now in houston and in south texas is harvey. and a lot of these daca recipients and family members are dependent on their income and their -- their support. so, yes, it's a big effect in houston right now. >> what would it mean for you specifically? >> so today i was actually helping my boss. her house flooded and i had a conversation with her about potentially by the end of tuesday next week, i would be turning in my resignation letter because i would be unable to work if trump makes a decision on tuesday to remove daca

permanently. so being able to poi for rovide family is a big deal at home. being able to pay for college. right? because undocumented students, unfortunately, do not get federal assistance, or do not qualify for loans, school loans. so being able to have a job provides me a greater opportunity and a higher level education. >> how important is the money you earn, ximena, to your family? >> right. so we have a small family. it's my mother and i, and my dog. and i'm the main source of income at home. and even though it is a small household, i'm still paying for all the bills at home and i'm still providing for my college tuition. and college, as we know, it is not super -- it is not as affordable as it was back then. so it is a big impact. but not just for myself, right. it is for other families. i run into other dreamers like myself who have a family of six. right?

and they are the main source of income for their family members. >> victoria, how do you explain this to students like ximena? how do you explain what's happening, victoria, to those who are saying, i don't get it. i don't see -- this doesn't fit in with the way i see what america means. but on the flip side, i understand that whatever the laws may be are the laws. >> right. and, richard, i have students like ximena in my classes here at the university of texas, and i see the smarts, the drive, the ambition, that passion to live the american dream day in and day out. so it really hits you on a personal level. and then the recounting of ximena also underlines the economic component of it where many times they are the main breadwinners. what i tell these students, both from a political science perspective but also a personal

one is you need to be engaged and informed politically. because the only way that you will make a difference is by making your voice heard. obviously if if you're a citizen, you can make your voice heard by voting. if you're not a citizen, you can also make your voice heard by mobilizing, whether it's demonstrations or whether it's contacting your elected officials and telling them your story. letting them know how you feel, what your contributions to this country are, working with folks who are citizens. there is a way to be engaged. so i think that we need to use this, this frustration, of the daca students and turn it into mobilization to get the latino community out. because we know, sadly, latinos have had a very low presence at the polls. and this is the fire in the belly that we need to get us there. >> as you so well know, there are so many thousands of latinos, as well as so many thousands of asians, as well as africans, as well as europeans,

are part of this number that we are talking about related to daca who could lose either eligibility or lose status. this effects a big fabric, a large piece of the fabric of america. ximen a, v ximena, victoria, thank you. breaking news, the south korean news agency reporting that south korea has conducted a ballistic missile drill. in response to north korea's latest nuclear test in the last 24 hours, the u.n. security council are now planning to have an emergency meeting in the morning, 10:00 a.m. eastern time, to discuss how to handle pyongyang's latest actions. joining me now, jonathan pollack, senior knell fefellow center for east asia policy at the brookings institution. things are moving here quickly. we have the u.n. security council moving again, though some would argue their moves in june did very little to mitigate some of the actions and activities coming out of north korea. we also have the response coming out of the white house.

and then the ballistic missile drill in south korea. what do you make of the ballistic missile drill? >> well, it's -- i'm not surprised by it. i wouldn't want to call it earth shattering. it is just something that you have to demonstrate that you are not utterly undefended in this context. but very frankly, the tests here that have gone on, going back again to yesterday's nuclear test, is no surprise at all. this is exactly what the north koreans have indicated for some length of time that they were going to do. they promised us in january that there would be an icbm test. they've had two. so i don't think anyone should be surprised. the question though is whether because of the scale of the nuclear test, the much larger size and yield of the nuclear test, that it is somehow redirected or will redirect a conversation maybe in a more urgent way. but very frankly, we are where we are and it is not a surprise. >> surprise versus concern. estimates of 100 kilotons in

terms of its power, the tests that they had done yesterday. that would make it six or seven times more powerful than the atomic bomb that was used in hiroshima. so we're just using the wrong word. it is not surprise. it is just heightened concern. >> well, what you have is a qualitatively different weapon yesterday, not a so-called fission weapon, what's most likely called a boosted fission weapon, not a true thermonuclear test but something far more powerful. shows a mastery of certain kinds of techniques probably that we did not fully anticipate. we don't want them to make a regular habit of it, to say the least, but it has a way of concentrating the mind. yes, there is no question about it. the issue though is what does north korea do next and what does the outside world do next? my real concern, very frankly, is that we are giving incredibly mixed messages. notions that we're going to pull out of the u.s./korea trade

agreement. you just don't do this to an ally that's under extraordinary threat, extraordinary pressure. but the administration, words can't do it. we have to look at this in a way that's candid, but more than this, there has to be message discipline coming from the white house that we just haven't seen. >> well then, jonathan, following that line of thought, is that why south korea has now conducted this ballistic missile test? not knowing, they're unsure of the support coming from the united states. >> i think there's some symbolism in it. i just wouldn't really -- i mean what the capability they have perhaps under some circumstances is to hit an incoming ballistic missile. north korea does not need nuclear weapons to threaten south korea. their pursuit of a nuclear weapons capability has much bigger ideas in mind, much bigger fish to fry, if you will. but there's definitely a feeling, i think, in south korea that they have to demonstrate to

their own people that they are just not rolling over and playing dead. i think the president's use of the term "appeasement" was dead wrong when he characterized what south korea's responses have been. there's nothing to indicate that they are just sitting with their hands folded, let alone that they are trying to make some major gestures towards north korea. that's not what's operative right now. let's just remember, it is korea, south korea and the 200,000 american citizens that are in south korea on any given day of the year. they are the ones most likely to be on the receiving line of any conflict that might eventuate. in that sense, that's where the focus should really, really by, i think first and foremost. >> in that catastrophic scenario, most likely conventional and/or chemical, not necessarily nuclear. >> you don't -- again, you don't need chem. >> that's what i was saying. >> again, south korea is under inherent threat because of location, because of the range

of capabilities that north korea has. very, very close to seoul. there's nothing new in that story. that's one of the reasons why deterrence has been so compelling and kept in place, more or less now, for 65 years. >> jonathan pollack, thank you, sir. >> thank you. coming up, actor harry connick jr., a new orleans native, saw his fair share of disaster after hurricane katrina. now he's moved to houston in the last 24 hours to understand the catastrophe they are going through and we had a chance to talk with him about hurricane harvey. reminds me of how geico has been saving people money for over 75 years. hey, big guy! come on in! let me guess your weight! win a prize! sure, why not. 12 ounces! sorry, mate. four ounces. i've been taking the stairs lately. you win, big guy. sorry, 'scuse me! oh, he looks so much more real on tv.

talk show host, harry connick jr., about his experiences in houston earlier today. no stranger to disaster, his hometown of new orleans was devastated by hurricane katrina and he picked up the shovel. >> these are the same people that opened their arms and doors and hearts to us after hurricane katrina. and their sense of optimism is absolutely incredible. they have a deep sense of faith and they're just fantastic people. i was so thrilled to be able to celebrate in this service with them. it is -- one woman came up to me at the end with a big smile on her face and said, oh, thank you for coming. i said, it is my pleasure. she whispered in my ear, i lost everything i owned. she kind of squeezed me and smiled and walk off. so for all of your viewers, boy, your prayers couldn't be more important right now. just pray for these people and i'll do the same. we'll all get through it together. >> you will, harry. i remember your interview on the "today" show, you were talking

through your father's house, this after katrina. so personal to you. and even recently when you were reflecting on your volunteer work, you got a jefferson award for your volunteer work during katrina. you still became emotional. this is very personal to you. >> it is. i always feel uncomfortable talking about awards and things like that because i don't deserve any credit at all. i'm doing what anybody would have done and what people do. i mean the volunteers down here are amazing. i mean my friends at walmart and sam's club just delivered a massive truck of stuff to this church and the faces on the people, i mean these people, they have nothing. i just met an incredible woman and her partner who have two beautiful kids who had to get their kids out of their house on air mattresses. they lost everything they had. they moved from pittsburgh. i love pittsburgh. they don't know about hurricanes in pittsburgh. they came down here and literally lost everything they had. to see their faces whether this walmart truck pulled up is a big

deal. it's an incredible place. i love this town. i love these people. and it is very, very emotional. so we really have to pray for them. we have to. and that goes to your viewers, by the way, no matter what you believe. pray for them. i got here early this morning. i have just been here a couple of hours and all of the credit needs to go out to the real heroes, first responders, cajun navy, everybody, who has done so much to help this town in its time of need. but one thing that i wanted to do was just come down and give people some hugs, tell them that i love them and they're going to be okay and get through it. it is so sad. i mean we're standing in an area right now in a square mile or so from where i'm standing, i was just told 12 people lost their lives. it is just a very difficult thing to overcome. i remember when i was in new orleans for hurricane katrina, you just needed to feel a sense of community and a sense of love and a sense of brotherhood and sisterhood with the people

around you. this is the time in your life when faith plays a big part and community plays a big part. so i just came down to do whatever i could to try to be of service and of emotional support to the great people of houston. >> harry, in the amount of time that you've been there, and it is early on, but knowing you and what you did after katrina for nola, for new orleans, what are some of the emotions expressed to you there in houston? something, unfortunately, that you know very well. >> well, we just came from the north shore community of fellowship of -- i don't want to mess it up -- fellowship of faith church where a pastor dixon just held an incredible service. i was very fortunate to be able to get up and talk to everyone and sing "just a closer walk with thee." the feeling there is incredible. it is no surprise to me. i know the people of houston very well because i grew up very close in new orleans. i feel blessed to have been

here. i am just looking forward to this amazing recovery process and watching the great people of houston and louisiana and everybody hurt by this storm, watching them pull through. >> humble guy. harry connick jr. thank you so much. the new season of his daytime show "harry" premiers on september 12th. connection your local listings for times. no doubt, he'll be talking about this story. next, we'll break down the north korean nuclear threat. dere plaque psoriasis,... ...isn't it time to let the real you shine through? maybe it's time for otezla (apremilast). otezla is not an injection or a cream. it's a pill that treats plaque psoriasis differently. with otezla, 75% clearer skin is achievable after just 4 months,... ...with reduced redness,... ...thickness, and scaliness of plaques. and the otezla prescribing information has... ...no requirement for routine lab monitoring. don't use if you're allergic to otezla. otezla may cause severe diarrhea, nausea, or vomiting. tell your doctor if these occur. otezla is associated with an increased...

>> secretary of defense, james mattis, suggesting the u.s. would annihilate north korea in a military confrontation. the statement coming after north korea carried out its most pow f powerful nuclear test yesterday, the explosion measuring a 6.5 on the richter scale. north korea says it would has the potential to strike the united states mainland. north korea released these photos purportedly showing kim jong-un inspecting the bomb. the question is do these pictures back up pyongyang's claims of their new hydrogen bomb capabilities. let's go to adam mount, senior fellow at the center for american progress. adam, you and i were talking about this just as the news was breaking overnight. i'm glad you can join us again. you so well described what little information we have. and so as we look at this

picture, specifically their claim, again, hydrogen bomb, number one. number two is miniaturized. number three, that they can connect it to a delivery mechanism. so this is just a freeze of one of the pictures here. what you described as a peanut. does this look like what could be a hydrogen bomb and what are we seeing here in this picture? >> that's exactly the message that they're trying to get across. they're trying to convince the united states and the u.s. public that they have what's called a two-stage thermonuclear weapon. that's why you see this peanut shape with the thin waist in the middle and the two round ends. they're trying to suggest to us that there is a fission first stage at one end of that warhead, that then compresses fusion fuel in the second stage of that warhead. what this means, if they were successful -- we can't validate this claim. but if they did create this kind of warhead, it means that they could build smaller warheads

with a greater yield that used less of their scarce fissile material in producing those warheads. >> as you look at the size of that, is it typical, based on your previous work in this space, does that represent what could be a miniaturized hydrogen bomb, two-stage? >> there's no reason from the pictures to believe that these are a fake. but, again, we don't know what's inside the casing that you see there, and we can't verify that they have surmounted all of the technical challenges that are necessary to shape those blast waves in the right way to compress and burn up all the nuclear fuel in the right way. so we can't be certain. but there is nothing there to rulegotcha. because they have misrepresented their statements or their claims before. >> yes, they have. >> this other picture i wanted to look at. it has what looks to be -- it is this sort of beige on the

lower-hand side of the screen here. is that what they are potentially representing as this missile delivery system, this icbm? is that consistent with what might be their claim? >> yesterday north korea said that they loaded this two-stage thermonuclear device into an intercontinental ballistic missile that they first tested in july. u.s. intelligence agencies and the open source community believe that this has an intercontinental range, plausibly that it could reach the intercontinental united states. we know -- or we believe that north korea has been successful in miniaturizing its first warhead designs to fit on top of north korean missiles, and they provided a convenient diagram in the background of that image that you are showing that has -- >> is that in the back left you are talking about in this picture? >> i can't see precisely what you are looking at but on the wall there is a poster that shows -- >> yes. >> -- a conical warhead with

that me nut shape on the inside. so they are very clearly trying to say to us very, very clearly, this is miniaturized and can fit on top of these missiles. >> finally, this picture of the back side, and it appears its a he got some black thing attached to it, as well as another cylindrical device sitting on a table. do we know what that is? >> my understanding is that this is meant to show that the physics package, the fissile package of the warhead. analysts will look at these images much more closely and try and give a better description later. >> right. it is very early on. finally, there is the estimation by csis that there is 100 kiloton-plus bomb that they had tested based on the various different reports of the size of the earthquake measurement that came out. that would make it six or seven times more powerful than the

bomb that was exploded over hiroshima. does that sound consistent with the understanding you have? >> there's still discrepant reports about the magnitude about the seismic event. also, we don't know how deeply the warhead was burr lid when it was tested. when we can fill in those two variables we can have a better assessment of what the yield of this test was. but it does, however, appear it was several times larger than the hiroshima bomb and the kind of bombs we understood north korea to have previously. it looks like this was a significantly higher yield. they told us for months -- for years that they were planning to do this, and now it appears that they have succeeded in greatly boosting the yield of that weapon. it could be the result of one of these two-stage thermonuclear warheads, or it might also be small enough that they could achieve that result, as you heard jonathan pollack say a couple of minutes ago, with

what's called a boosted fission device that uses a thermonuclear fuel but not in a two-stage configuration. >> adam mount, it was great to have you overnight to break this down for us. greats to have you back. again, a senior fellow at the center for american progress, as well as a nuclear expert. this is why you can break down this stuff, formerly there of cfr. thank you, adam. >> glad to be back. september to remember. some major tests ahead for trump and his young presidency. it is going to start in earnest on tuesday. hurricane harvey. tax reform. there is the debt ceiling. daca. the list goes on. the question is how will president trump deal with all of this in a very important month that's about to start? we'll dig into that. with the o make a claim and all that? is that whole thing still draggin' on? no, i took some pics with the app and filed a claim, but, you know how they send you money to cover repairs and - -they took forever to pay you, right? no, i got paid right away, but, at the very end of it all, my agent- -wouldn't even call you back, right? no, she called to see if i was happy,

but, if i wasn't happy with my claim experience, for any reason... ...they'd give me my money back, no questions asked. can you believe that? no. the claim satisfaction guarantee, only from allstate. switching to allstate is worth it. when heartburn hits fight back fast with tums chewy bites. fast relief in every bite. crunchy outside. chewy inside. tum tum tum tum tums chewy bites. you don't let anything lkeep you sidelined. come on! that's why you drink ensure. with 9 grams of protein, and 26 vitamins and minerals... for the strength and energy, to get back to doing what you love. ensure, always be you. you're going to be hanging out in here. so if you need anything, text me. do you play? use the chase mobile app to send money

it is a busy september coming for the president as well as congress. here are some of the issues for the agenda, securing the aid funding, and relief for harvey. there is also passing a federal budget, there is finally tackling tax reform in addition to that and possible another attempt in healthcare reform. of course, the feud between the president and lawmakers from not only his own party but democrats. there is still uncertainty of what the president will be able to accomplish. lets bring in our editorial writer, we have richard payner under george w. bush and robert tranum. dave, the list goes on and on,

what's going to concern most folks across america is the issue of the debt limit. will we have to close down many of the services will be opened day-to-day. harvey will have an impact on that. how will this be handled by both congress and the white house? >> well, you would guess a month ago that a government shut down is not likely but possible. that's almost in conceivable now between the harvey relief package that the congress have to put together and crisis in north korea. you put two things together, the idea that the government will shut down in the middle of all that, i don't think the president or his supporters in congress would want that to happen. my guess is that's off the table and now the members who are involved in these discussions will have to figure out which piece to put into which place to get some sort of overall vote by the end of september. they got to redo the children's

health insurance program. the flood insurance program runs out in september. there are all sorts of things have to be put together. >> all of the end of this coming this month rather as they return to congress. >> robert, are those the extra urgency that'll push some sort of solutions whether you are a democrat or republican and i am going back to david saying those will be north korea and harvey >> yes, there are three things here, they are all related. first, there is harvey relief for texas and louisiana. that's going to pass when congress comes back from recess on tuesday. there will be a spending bill keeping the government opening between now and december 31st. it is in conceivable that the government will shut down between now and the end of september. there is a strong possibility as i mentioned that the spending bill will go until christmas.

it is very conceivable that the government could shut down at the end of the year. i think that's probably very likely so three separate things. a short term spending bill and a clean harvey bill but also some type and the the debt ceiling. that's another big deal that congress had to deal with. the faith and credit of the government on the line is never defaulted on our debt. it will probably pass by our bipartisan support. they know that republicans cannot pass on their own. they know there will be some democratic votes there. i think that's where you will see democratic flex their muscles. treasury secretary from the white house saying mnuchin's saying we got to take a look at this. if we are going to give money to harvey, we'll to deal with this. richard, john mccain, was calling for congress to get back

to being productive. we got to get some stuff done. he also said to do so with some respect and some loyalty to the president, mccain writing "inin must cooperate with him but we are not his subordinates. >> did he alienate the stuff he needs to get his stuff done. and over the healthcare bill and a number of issues. and now we have the decision to be made of the dreamers program. there again is an issue that the president could alienate a lot of people in the republican party if he decides to prevent

these people came over here to the united states as children from working here and a lot of republicans and democrats want to see immigration reform as president bush did. and i think the president trump needs to seriously consider whether an extremist agenda approach and so forth is productive. if he works with members of congress, he can get it done. he needs to reach out and work with them. >> hang on a second, robert. >> i do want to get over to dave here, as we saw in the maobama administration, early on there was one big grand slam and that was healthcare. what maybe that for this administration. >> tax reform if he can get it by the end of the year. i don't think that's overwhelmingly likely given all the other things on the agenda. if he can do a significant, sign a tax cut measure by the first of january, i think he can count

that. >> sorry sir, we ran out of time today. that wraps up for us here, itch richard louie, for now, "meet the press" is next, stick around. oh, you brought butch. yeah! (butch growls at man) he's looking at me right now, isn't he? yup. (butch barks at man) butch is like an old soul that just hates my guts.
