china has a very small arsenal. and it's complaint being to have a small arsenal and also to adopt, especially if you have a small hours of all, you should've taken a new option to reserve the right to strike first. you should have a large ours and all. so china's ours that all has to satisfy three requests. first it must be small. msb second straight. third, mst terror. how do we do all these things with a small arsenal? first, china has to have a survivable nuclear arsenal. maybe it had found relation with the panels. the united states have panels. panels are to increase survivability of a very small arsenal. they have to a penetration, capabilities because after army strikes, the small arsenal must have much to strike back and china's arsenal has to be -- has to deter. they have small uncertainty, not transparency to deter. a certain amount is an integral part of china's policy. >> i'm going to invite people to start moving into the questions session and always plenty of time. that may ask why you are doing a tra

in a spectacular murder series, several women kill their husbands with arsenic. they were discovered and sentenced, but today the region is dealing with our sec again, albeit for a completely different reason. >> some 160 men who died of arsenic poisoning live buried in cemeteries. most were killed by their wives in the years following world war i. women known as angel makers got our senate from pesticides, usually from flypaper. the merger international attention. two women were executed and numerous others sentenced to life in prison. today are sick is once again making headlines in the same region. nicolette lives here, but until recently, she had no idea that her drinking water contains levels of arsenic which far exceed those considered safe. each leader contains 15 micrograms of the poison -- each liter. >> we did not know there was our sec in the water. i think most people still are not aware of it. to date, nothing has been done about it. we simply have not been informed. >> but thanks to the european union, that might be about to change. at the beginning

china has a very small arsenal. china has always been having a very small arsenal.seems paradoxical, it seems conflicting to have a small arsenal and also to adopt -- [inaudible]. if you have a small arsenal, he should have taken preemptive doctrine to preserve, to reserve. if you have no u.s. party state you should have a large arsenal. so china's arsenal has to certify three requests, demands. the first, it must be small. the second, it must be second strike. and the third, it must deter. how did you all these three things with a small arsenal? first, china has to have a very survivable nuclear arsenal. maybe that have some reason, had some relations with the panels. we have panels. the united states has panels. russians have panels. titles are to increase the viability of a very small arsenal. and china's nuclear arsenal has to have penetration capabilities. because after a second, a first strike, a small arsenal will not have much to strike back. and the third, china's arsenal has to be common has to deter. and it has to be stopped more and it has to deter. so c

in other words, we've demonstrated that progress can be made in reducing arsenals. and the new start treaty that president obama and medvedev of ssiaave gned is a very important step towards reducing our nuclear arsenals down to zero. because the us and russia have about 90-odd percent of the nuclear weapons in the world today. if they continue to make severe cuts in their arsenals, which leaves them, by the way, with more than enough weapons to destroy the world over, so they're not cutting back in this new start treaty in any way that will make this country less secure. and that is what all the military experts say. they all support this new start treaty. the military leadership of this country supports the new start treaty, because it will take the us and russia closer to bringing together the other nuclear states when they see that the us and russia really are serious, and don't intend to keep weapons while telling everyone else they can't have them. then you will find all countries, including countries like iran... if they feel that everyone is being treated th

that produces a nuclear weapon in iran that somehow you can blame that on the israelis and their arsenal is farcical i think that iran that there are many other reasons why iran would want to have a nuclear deterrence and it's not simply the existence of the israeli arsenal there are hedge amount of power in the area and they're also as a shia country they have real serious serious concerns and if you look at a map of the united states they're pretty much surrounded so there are other reasons why they might want to do it but the idea that it's going to somehow spawn other political what thomas brought up is a very good point i think we should discuss that saudi arabia is obviously the first country that people look at but other than that i don't think that the risk of a rapid amount of political taking place in the area is likely just doesn't seem to be in the cards right now in terms of how that's going on so i think it's a double standard us thinks and it's a jumbled standard moment right. yes i mean even the talk that iran is produced attempting to produce nuclear weapons is completel

right across where a lot of the footage that you were seeing along arsenal street and where the arsenal mall is, you're a stone's throw if they turned the cameras around you'd see boston on the other side of the river. >> i imagine you're not a native. >> i grew up in central massachusetts. >> you don't have the -- as severe a boston accent as the die hards and true believers do. thank you, doctor. what an eventful night you had at work. what a key decision to bolt out the door and go to work. we have been listening to dr. david, who heard the shots and ended up reporting to work and seeing what we now know as suspect one. kerry sanders was among those on our team originally assigned to this story in boston. then came word of the cop shot in cambridge, not far from the harvard campus. then came word, shots fired, three explosions in watertown, mass. >> reporter: it's been chaotic since really. arriving in watertown in the aftermath of the explosions and the shootings, the officers were so concentrated on what they were dealing with and i'm talking about more than 100 officers that as a

are you on arsenal? >> when the shooting happened, we were actually right at laurels, the scene of last night's shooting, talking to a resident with the rear window shot out. >> you heard the gun shots? just looking on the map, it's not that i mean, it's not terribly far away. it's certainly, i'm -- i don't know, about a quarter of a mile, i'm guessing, when you heard rapid fire, when you believe sounded like fireworks? >> absolutely. very clearly and as i said, ironically, after listening to the recording of last night's shooting, the guy with us is playing it and we heard it in the distance and he said that is what it sounded like, it sounded like that. we were listening to rapid fire, gunfire of last night's recordings. i'm arriving on the back end of the scene with flashing lights. >> there's a big scene where there's a number of officers in the streets, you can hear the sirens, we are looking a a number of unmarked and marked police vehicles. just said he was in the area where there may have been 20

it's a huge shopping mall, the arsenal area. so i think what we are going to see is their confidence level he's in a certain area. you may start to see over the course of the next hour actions that would sort of warn bostonians, people in cambridge and watertown to just stay put today. and so let's wait out for that. i don't want to jump the gun, but as we hear each of these, they are going to sort of evacuate people from watertown. they are going to close areas near arsenal mall in watertown. what are they going to do with the t? do they want people coming into the city? >> that's the public transportation. >> yes, sorry. people will get back to normal and how do they want people to behave? the good news is schools are not open this week. most public schools are not open, so people will stay with their children and hopefully this unfolds rather quickly. >> if you work in watertown, probably a good rule of thumb, call in sick today. it's probably a good idea just because there's going to be a lot of police activity in that area.

-- in our strategic arsenal.nd our south korean allies know this and, i believe, accept this. i think it's very important at this stage of the game to insure that there is the utmost confidence in that extended deterrent by our south korea allies and our japanese allies as well. and i think that the obama administration with the b-52 deployments, with the b-2 deployments and other statements we've made have done exactly that. that's the right way to do it, to respond to this crisis. not by making it even more complicated by reintroducing nuclear weapons onto the korean peninsula or having the rok develop its own nuclear weapons program. >> okay, thanks. we've spent a lot of time analyzing the situation, and now we want to turn at the end to what to do about it. and evans has made the important point that, um, as much as one would like a role for diplomacy and negotiated sort of solution or management of these problems, the conversation that the united states wants to have now quite different from the conversation

occasions, we sought to negotiate with them to at least halt any further addition to that arsenal and then eventually to start rolling it back, to actually take steps as it did before to move towards dismantling the weapons arsenals, the weapons complex that supports it. again that's the kind of thing we'd like to get back to in negotiations, but i think it' up to north korea to demonstrate some kind of good faith that it's ready to get back on the denuclearization path. >> charlie: that should be a precondition to any direct talks. >> i think it has to be at this point in terms of we need some serious action that indicates a change of course on their part. you know, we've had a number of negotiations over the years. as my old boss, secretary gates, used to say, we have to avoid buying the same horse twice. there have been several times when north korea has said, we'll stop producing plutonium if you just give us this aid. we give them the aid. they stop for a little bit and then they start again and they want more aid to stop it. i think we have to be very careful about getting into

in his house they found an arsenal. would any of the laws they are talking about have stopped him? >> i don't think so. the gun check thing would not have made a difference. it was his mother's. >> yes, and she gave him money to buy it. had nine knives, a lot ofurai swords, ammo. coaste guilty of east elite is some, but as a parent, yourn't you be curious if kid had an arsenal like that? >> she was supporting him. and if the people in the school were armed, it would not have made any difference either. it probably would have gotten more people killed. >> he was disturbed, and probably the mother was as well. hard to see, it is how a law based on irrationality would have any effect. all of bp debate about a a -- all of the debate about guns wn has been about acquisition. is the tucsonle shooter. everybody knew and was saying out loud this guy was dangerous and they knew it. but until he killed, you were not able to apprehend him. >> your colleague wrote a fascinating column this week. he talked about how homicides have been reduced 80% in new york city. they focused on the area wher

meanwhile the north koreans keep building up their arsenal. how do we try to arrest this process? book jonathan pollack's enough to know it is not going to be easy. we're all conceding that the north koreans really want these things. we have to break down the problem a little more incrementally. kim jong il could be in power for the next 50 years. we may be getting and little tired of applying sanctions. we have been doing pretty well. are not in and iran the places. kim jong il is going to have to he want toce. does reform or stay running the fir hermit kingdom. we want to play for the longer game. i could live with a deal that did not give nuclear status to the north koreans. loosen a little bit of the restrictions if they stop expanding and testing and stop killing south koreans. we can start walking down a path a little more gradually. it is not getting us very far year by year now. >> just one other observation here. this is a hypothetical you have posed. this is a different topic for a different time. wether the north korea that see today in terms of its identity and purpose

this is arsenal ware. where there's a lot of activity today. here we go. this is what we're talking about. i don't know if you can hear that. you can hear the cheers up and down arsenal as this convoy of cars is coming down. they are leaving the parking lot where the photographer chris and i were for several hours tonight. we just want to make sure you can hear these guys cheer. these are folks who have been in their house all day. they are so relieved. they are so happy that this ordeal is finally over. that they are safe. and we've been talking to crionza who can't believe this is finally over. so i can show you the celebration all night. but a lot of happy very relieved folks here right now. crianza. tell us how you're feeling right now after a long day. >> i am very happy. thank you, thanks for everybody. this is wonderful job. oh, thank you guys. >> thank you. >> reporter: so a lot of celebration tonight. especially after a very tense stand off. a lot of very frighten sounds. explosions, gunshots now a little bit of celebration and obviously the polic

why iran would want to have a nuclear deterrent and it's not simply the existence of the israeli arsenal there are hedge amount of power in the area and they're also as a shia country they have real serious security concerns and if you look at a map of the united states. they're pretty much surrounded so there are other reasons why they might want to do it but the idea that it's going to somehow spawn other put for ration i think what thomas brought up is a very good point i think we should discuss that saudi arabia is actually the first country that people look at but other than that i don't think that the risk of a rapid amount of political taking place in the area is likely it just doesn't seem to be in the cards right now in terms of how that's going on i think it's a double standard us thinks and it's a jumble standard moment right. yes i mean even the talk that iran is produced attempting to produce nuclear weapons is completely baseless and the iranian nuclear program has always been peaceful seems doesn't seem to be enough for some people in the west because they went in when it

>> well, we are here still at the corner of arsenal -- or mount auburn and langdon. this is an active scene in the area. we have seen things pick up in the recent 10, 15 minutes. we are getting a lot of information about possibly the suspect could be moving. we have seen officers going up and down the streets shining them into homes as you think they would with the search going on. we have seen activity and cruisers going by in the area in the last couple minutes. of concern are we are beginning to see the lights come on in this community. we are begin to go see people peeking out of their windows. this community is waking up as this search appears to be getting more and more active in the early morning hours. at least in this neighborhood. we are a few blocks from an area also being described as a very active scene. we can't quite see over the hills where those blocks are that police have been talking about. we are keeping an eye on it. right now we are just waiting. as you can see behind me they are blocked off. only so far we can go but from this vantage point thi

on sunday the workers party warned of the nuclear arsenal is the country's life and will not be traded even for billions of dollars. kim jong-un ordered rocket units to set targets on u.s. bases in the region and put soldiers on standby for war. more now from seoul. >> monday's meeting of the supreme people's assembly is an annual event that happens around this time every year. an opportunity for their leadership in north korea to cement any policy decisions and budget and often, interestingly, promotions and appointments to senior positions. that is something to watch very closely by those looking to see if there are signs of change or continuity in north korea. what happened last year is there was an extraordinary meeting of this body as well in september. the run-up to that was full of speculation kim jong-il and -- kim jong-un o nouns economic reform measures. this time there will be speculation as to whether such measures are announced. one reason for so much over-the- top rhetoric from north korea in recent weeks has been that been that they have been trying to get the military t
