Censuses. The president elect told you what . Let it be an arms race. Well out match them in every pass. And out last them all. Vladimir putin took a question at his annual press conference this morning. When someone accelerates and speeds up the arms race, it is not us. Joining me now is nbcs kelly odonell and katy tur. Kelly, you are in florida and mr. Trump is spending the day playing golf with dwootiger woo. How is this leading the republicans in trumps team. Reporter one of the questions is how seriously or literally should Donald Trumps tweets be taken . Is he trying to set policy through twitter . Is he trying to preempt president obama of his final days by showing a change of force for u. S. Policy . These are open questions and it is coming to holiday times when members of congress are all comiing home to their families. There is not official washington is standing up and react to what donald trump is doing. You have Foreign Policy experts who are outside of government and those specialty in government and Court Concerns of what trump can do and could shake things up a little bit. As president elect trump, and the world views and what he tweets differently. We have seen his squirmishes with china when it comes to what happens with the under water navy drone that was taken with the phone call with taiwans president and a willingness to throw his illelbows around and when you talk about possibility of expanding the arsenal of u. S. Nuclear weapons when the whole Foreign Policy, the whole direction of u. S. Leadership and the world was to try to limit the proliferation of these weapons and to make certain, the great fear is could those kinds of weapons getting in the hands of not state actors but complicated enough. Thats one of the great reasons why over the last several years and in the wake of this terror age that we have been living since 9 11, there is such concerns of access to Nuclear Weapons. Donald trump is talking about modern siizing the u. S. Thats a very specific thing, kelly. It is a good point that you made because thats specific. The agreements between the u. S. And russia inherited from the u. S. Is specific to maintain and modernize and not add to. Kellyanne conway, one second, katy tur, you sort of get it and you have the intimate relationship with the way that Trump Campaign can work and what it can mean and how everybody goes into over drive after donald trump says something they did not think hes going to say. Sean spicer just minutes after president elect trump made those comments. Lets listen. We are not going to sit back as a country and allow other countries to expand their capabilities. This president is going to take action. It is a warning to them that this president is going to take action. Sean spicer, in coming white house, press secretary. Whats the warning about this . Kelly just said who is he talking about . Is he talking about russia or china or north korea or france . It is unclear who hes talking about. He has 140 characters. You dont change policies in 140 characters especially when it comes to Nuclear Policies because there are so many ins and outs. This sort of thing that you tend to think about and present in a k cohesi cohesive. Donald trump does not do that. Hes nontraditional. Was there a lot of thoughts behind this. I was speaking to somebody a little earlier. Maybe it is something that he heard an intelligence briefing and he was reacting to on the fly. We dont know what was in the intelligence briefing clearly because those are classified briefings and donald trump did not say what specifically he was referring to. We assume russia because russia had been talking about this the day before and talking about Nuclear Operations and capabilities were modernized and making sure they are up to speed and bringing them current to 2016, almost 2017. There is a whiplash here. Donald trump has been generous to russia up until now and the idea that he was going to be in arms race and his aids clearly are trying to walk that back and calm it down and Kellyanne Conway on Rachel Maddow last night everyone is getting ahead of themselves. It showsou that donald trump is telling lewandowski, lets get an arms race. His aids are forced in a moment to turn on a dime to decide what suddenly, they need to defend and promote. Katie and tekelly, it has be a long time. Both of you thank you. Lets bring in our president of an organization focused on reducing Nuclear Weapons worldwide. Joe, i need to get your reaction. I want to begin with the numbers of your group cited in the usa today, russia has more than 373 Nuclear Weapons and the United States has just below 7,000. No other country has more than 300. What do you make of what you heard . Well, the u. S. And russia of the two Nuclear Super power, we own 95 of the arsona s is ars in the world. It is a message to other countries to start their engines. China is watching us closely. They have about 250. Theyre going to Start Building more and india and pakistan, theyre going to Start Building more. Thats why this is so disturbing. Let me ask, is this about modernizing or strengthening . Nobody really knows. What would you instinctively think and knowing as much of this. We are going to keep a robust de detorrent. He used the word expand which means more. And then he says nod let there be an arms race, thats why people are worried about it. It is okay to use twitter to make fun of saturday night live or hollywood stars but you should not screw around and Nuclear Policies. This is a man in 30 days thats going to have the control and authorities to launch Nuclear Weapons and not just tweets. Let me ask you this, we talked about the u. S. And russia and thousands of war heads on either sides. Even when the u. S. When russia went into yukraine, we did nt think it will escalate to that level. We were so obsessed with iran for a while which does not have the nuclear weapon. North korea has nuclear capabilities. Maybe ten. I think your more important point is that it is not that we are going to war with rush whsi. We may open up the possibility to others that hey, we want some. One, this kind of rhetoric can escalate. This is how arms race can start. A war of words. Two, you worry about the global reactions and a signal to other country that they should increase and build more Nuclear Weapons and three, you worry that in the course of this, you are creating news supply of weapons that trorists can get their hands on. All of this are considerations that donald trump should have had. We dont know if he thought about this. I want to ask one quick question of what Kellyanne Conway says. A worry that we had today than 30 years ago is the idea of Nuclear Weapons in nonstate hands. Is that an issue . Here is the good news. Because the policies of republicans and democrats are followed, we reduce Nuclear Weapons by 80 in the world in the last 30 years. When you talk about rogue states and you hear about all these threats out there, there is only one, north korea. We just contained irans program and we froze that to 15 years so you are down to one. Maybe donald trump can strike a deal with kim jongun, that could be a deal that well put in the history book to cut those Nuclear Weapons. Lets hope he uses it and uses it early. Thank you very much for joining us. Lets go to pennsylvania, our bob casey. Senator casey, welcome to the show, i got to get it from you. Thanks ali. I was surprised because many people are in both parties. If there is one subject that you should not tweet about cavalierly or even in terms of a short message, it is Nuclear Capability anlilities and weapo. We have to be deliberate and smart and prepare. And not only to protect the country but to do it in a way to use some discretion before you comment on this. It is alarming. What are you and your colleagues president elect trump is not president yet. This is definitely a place where the cooler heads in the senate on a bipartisan level probably need to make some phone calls or get together and talk to each other and say what are we doing about this . Well, i think as the new administration comes in, we may have to have that kind of collaboration. Al, you know that just six years ago, we passed a new start treaty which got 71 votes in the United States senate. It is a 7year implementation. The United States are going to have a lot and a lot of war heads and a little more than 1500. Thats awfully a lot of Nuclear Weapons. If hes talking about maintaining the investments and making our system, thats one thing. Our country is going to spend something on the order of 350, almost 350 billion, and thats with a b over our ten Years Nuclear enterprise, we are investing a lot and focused on modernizing and being vigilant prepared. What do you make of the Letter Exchange and holiday greetings and the warm relationship of Vladimir Putin and donald trump and Rex Tillerson of the next secretary of state probably with his great relationships with russia, was your instinct that when donald trump was talking about an arms race, hes talking about russia . I am not quite sure. I dont know him to be able to get a sense of his thinking. I only see whats on television with regard to things he said by way of twitter. Vladimir putin is no friend to the United States. I would hope that president elect trump and ultimately President Trump would focus on checking on Vladimir Putin and keeping him contained as opposed feeding to a narrative that Vladimir Putin is along Bashar Alassad and the regime in charge in places like syria. We got to be checking him and even as we are working him when it comes to trying to defeat isis. Even that, hes got a very mixed record on. I would hope that the approach would be adversarial and one where we dont have any illusions and they are not consistent with our national interests. Senator, your colleagues in the senate and both sides of the isles are going to have busy times ahead. Thank you for joining us senator bob casey. Thank you, ali. Breaking news, Agency Releases a video reportedly showing the german Christmas Market attacker, pledging allegiance to isis. The comes hours after the suspect was killed in a shoot out in italy. We are learning more today about am amris movement while he was inside europe. Later this hour, how president elect trumps tweets are sending shock waves around the world on everything from Nuclear Weapons to the palestinianisraeli questions. Stay with us. Hello, we want to wish our family and friends happy holidays. In muskogee, oklahoma, love and merry christmas. Because no one kills germs better than clorox.

Because our pets deserve it. Beyond. Natural pet food. We are following breaking news out of italy of the suspect of the truck attack was shot and killed by police. Anis amri was a subject of a massive europe wide manhunt since authorities named him as a suspect on wednesday. Isis released a video which a man says it is amri. He does not identify himself as amri. He does not say his name or reference the attack in berlin. Today, many are wondering how amri was able to make it to 600 miles away to milan italy. We have matt bradley following the latest with berlin. Clau claudio, what do you know of how this all played out this morning . It was 3 00 in the morning and it was a quiet neighborhoods, just a few miles and from the city center and two young policeman patrolling the area. The suspect was just Walking Around and kind of weird. Of that time, the early hours in the morning. They went out in the car and offered his id. Th he pulled out a. 22 caliber and shot one of policemen in the shoulder and the other one was prompt enough to fire back and shot him dead. Later, they found out this was anis amri of the man carried out the attack in the berlin market. Now, theyre trying to find out why he end up in italy and it is a small town where he can just stay in italy or milan. Was he hoping to find someone who perhaps helping him . We are trying to find out an answer to that. To be clear, you travel these distances, it may be 600 miles but they are notrd bo border ch. It depends. Thats exactly what hes done. Thats close to the italian border and he crosses into the Northern City there and he took another train and went to milan and from milan he took another train and ended up if you want, you dont have to go to border checks. Just get a train unless you have police on board and the government asking you for documentation for id. You can freely cross from one to the another. Matt in berlin, what are you hearing from folks there about the news of amris death. Reporter despite all the tragedies thats happening this week. Christmas in full effect behind me of the scene of the massacre of last week. Things are a little intense. The chancellor merkel came out today. Shes been assailed by the critics and mostly on the right who says her open door door policy, she allowed a million refugees over the course of the last year and a half, the policy states opening the door to them and now critics are turning their heel and they are using the capture of islamic to beat with her. So many people from the netherlands and france and britain, all have been tweeting that all of this goes to show as claudio just mentioned that it is so easy for a fugitive to cross the border. It needs to be revised and evaluated. The politics here are really whats important and we have not seen the other foot drop. Matt and claudio. Thank you. For more, i want to bring in our analyst, executive editor of defense. We have been talking to the cabinet people for the last few days of the fact that people are under surveillance whether in germany or america, does not mean that there is Police Presence watching this person 24 7. Right, as you heard them say you can hop on a train or on board and you can lewd conductors. It does highlight the real difference of the security concerns in europe verses america. This all gets down to how much Border Security is needed and how much in the region and how much security needs to be focused on the local population that are home born and verses one that comes from outside the country verses the refugee crisis population. There is a lot of con exfoliaal. It was about our Border Control and the focus on syrians a musl refugees. You cannot come to the United States like this guy did who went three Different Countries to europe. I want to ask you, isis released a video where a ma man he pledged allegiance to ai isis. Whats your take . Is this authentic. It comes from a lot of Intelligence Watch groups. It does not matter whether he recorded beforehand or not. All we know is that it links to isis and links to the movement. There were plenty of other evidence that this guy had a long history of either trying to or carrying out attacks in europe. It provides a little more evidence and link him to other network on the continent. It is not a major point for me to worry about. I am interested in of whats going to be the outcome that are here and being float about. Kevin goodo see you, thank you very much for joining us. Breaking news right now, the United Nation voted moments ago to approve a resolution demanding an end to israeli settlement of the west bank after a one day delay. The United States did on stabta from this vote. It did not veto it. President elect trump has urged the Obama Administration to veto the resolution and it is coming under fire from both republicans and democrats. Lets bring in our msnbcs senior editor, cal perry. This just took place, walk us through the vote that just happened and the ramp up over the last few days. The vote just happened, 14 yes votes. The resolution is adopted booy e United Nation. The occupied west bank will stop and that means to halt and relocate what are 500,000 settlors who lived in East Jerusalem and the occupied west bank. This is coming from the United Nation which in the reality is this is a landmark moments certainly not just for the United Nation which rarely agrees on anything that the palestinians and israelis are related. This is also a landmark moment for the Obama Administration, and their policy towards settlements. The Obama Administration has viewed settlements as a major to impediment to peace and to the israeli and palestinians. There was some question as to whether or not late today that would still happen. Again, the u. S. Obtaining from this, this was a
