And dodging dangerous debris out in space. And movie music. A weekend revival of one of hollywoods most recognizable riffs. A day of defiance in ukraine, Vladimir Putin made a dramatic appearance in the newly annexed region of crimea. He was there for eventing celebrating the end of world war ii. At the same time ukraine saw some of the most intense fighting so far between prorussian rebels and progovernment forces. It happened in donetsk where people are about to vote on their independence. Reporter the fire burned well into the afternoon. The Police Building near the center of the city had clearly been hit by heavy caliber weapons. On the ground. Traces of blood. And bodies. At least two still there, this one a policeman. [ gunfire ] reporter this is amateur video that we collected at the scene. What happened here is extremely unclear. A ferocious fire fight no doubt. But nobody seems to know who was shooting at who or why. According to official reports from the governments units of Ukraines National Guard moved in after 60 people armed with automatic weapons tried to seize the Police Building. They apparently fought with Police Inside the building. Eyewitness accounts are a little different. This man said he was afraid of reprisal and didnt want to be identified. Translator there were police in our building. They refused to follow ordered, and thats why the National Guard attacked. Reporter witnesses said as the National Guard retreated they were followed by an angry crowd, so they starting shooting into the crowd. A broken down Armored Vehicle was seen being toe towed away by citizens. Ukrainian police and soldiers kept close watch outside the city. Jennifer glasse joining us now. John the prorussian separatists say they are going ahead with the referendum on sunday to declare themselves independent. On sunday this school in the eastern yushg city of donetsk will become a polling station. Translator we think that everything is ready. We dont have the ballot boxes in place yet, but today and tomorrow we have meetings to prepare. Reporter the cities of slaviansk and [ inaudible ] will hold a vote too. Russian president Vladimir Putin called on the vote to be delayed but the separatists are going ahead anyone. Ukrainian officials are concerned the poll will be used to lay the future ground work with russia. A repeat of the vote in march when the poll was followed by the declaration of independence. First there are logistics, printing all of the ballots and finding polling places. Its not even clear who clear who controls the voters lists. Translator its only be used as propaganda by russia. Reporter Ukrainian Security services released this video. They said they are not ready for the vote. The man in moscow telling him to make up the votes. The usc will certainly not recognize a referendum of this kind. Obviously if it goes ahead it will create facts on the ground that well have to deal with. Personally i dont think its a good idea in this moment. Reporter the separatedists dont control the entire territory just many government buildings, and its unclear how widespread the vote can be. And were not sure what the outcome the people there are hoping for whether they will try to declare independence or use it as an excuse to get closer to moscow. So we have sundays vote in donetsk. How is that going to effect ukraines upcoming president ial election . That is the real concern. The aim is to get a government in to kiev that can be recognized by the rest of the world. Moscow has repeatedly refused to recognize the interim government. They are hoping the election will bring legitimacy to the government in ukraine. Jennifer thank you. Almost two months ago people in the region of crimea voted to leave ukraine and become part of russia. Today Vladimir Putin came to crimea to commemorate the end of world war ii. Reporter sailing past russian warships president Vladimir Putin arrived, and as expected he alluded to russias annexation of crimea just two months ago. Translator im sure that 2014 will go down into the annals of our whole country when the nations living here firmly decided to become part of russia. Reporter he also received a helicopter and jet parade. And earlier in the day a march watched by 10s of thousands of people. Victory day is a big deal across russia, but here they are also celebrating 70 years since the soviet army liberated from the nazis. Many spectators drew parallels by the push by some to break away as well. Translator now i understand what they felt during their victory day and when peace returns to ukraine, well celebrate their victory day. Reporter this man served in world war ii. He is proud people remember the era, but he is thinking about more recent represents here. Translator crimea became russian without the use of any force. There have been stories about people with arms. Its all nonsense. Reporter for russians victory day is a chance to commemorate the defeat of fascism. Many people believe a similar struggle is underway in ukraine. And the appearance of their president made this occasion especially important. Matthew schmidt is a professor of National Security at new haven and joins us tonight villa skype. He has been appointed as a monitor to oversee the up coming elections in ukraine. Welcome. Thank you. What is your reaction to Vladimir Putins dramatic appearance in crimea . It was a victory lap. It was great optics for him back home. It puffed him up to the public in russia, and a finger to the government in kiev. You have been selected as an election monitor. What are the Biggest Challenges of this upcoming vote . Well, i think the challenge is going to be to have the vote come off in the east and the south of ukraine with the same level of rigor that is going to come off in the west of ukraine. I think it will be very difficult for the provisional government to do right now. Given the situation in cities like slaviansk. Well, how do you do it . How do you pull off a safe vote in ukraine now . Im not sure. I think you just try to do your best. Okay. Vladimir putin said that he backs the Upcoming Elections as a step in the right direction. Do you really believe hes going to respect the results of the election . Im not sure. If you watch putin closely what he does in every case is leaves his options open. So for instance, in calling for a delay in this referendum in the donetsk peoples republic. He has bought the option to either accept or reject on his timetable. I think hell wait and see what the situation looks like and decide if the candidate who wins is someone he can work with, or if he thinks he can get more by calling a legitimate election. You have seen this violence in eastern ukraine. Tell us how you would categorize it. I believe you told your producers its the essence of modern war fair. Yeah, the russians have a word for it, which means Something Like masked war fair. You have [ inaudible ] special forces and russian intelligence agents and you have locals who are exmilitary, and exspecial forces and military contacts all working in concert with a certain portion of the population that is in fact a willing participate president ant. If you remember they waited and delayed and tried everything they could not to do that, and now they have to. And as we can see in places like odessa or slaviansk, the results havent been very good for them. Clearly the fighting goes on and the conflict continues. Matthew thank you very much. Absolutely. A Major Development in the south sudan conflict. The president has signed a ceasefire with the rebel leader. The ceasefire should take effect within 24 hours. Both parties agree that a Transitional Government offers the best chance for the country to move forward. The un has accused both sides of crimes against humanity. 5 Million People are in need of aid, and were going to have much more on what the ceasefire means and what happens next in south sudan coming up at the bottom of the hour. The Nigerian Military was warned in advance of a boko haram attack that resulted in the mass kidnapping of schoolgirls. Two politicians have told al jazeera Security Force were given at least a twohour warning but did not act. Reporter could this have been avoided . Sources have told al jazeera, and Amnesty International that nigerias government ignored warning that left boek ka haram free to kidnap over 200 girls. They were outgunned and the number of boko haram fighters who attacked the town, and they had to flee for their lives together with some villagers. And thats a shocking revelation. We have been repeatedly calling on the nigeriian authorities to provide adequate security, especially for schools, because the schools have become vulnerable targets in the last couple of years. Reporter the governments response has lead to protests across the country. Specialists from the u. S. And uk are now in nigeria to help with the search. The nigeriian government says it will investigate claims the military ignored warnings of an attack. If the claims are substantiated it will likely deepen pup lick outrage. Retired Army Major Mike Lyons joining us from new york. What is your reaction that the police had twohour warning that this might have taken place . Its really no surprise. The nigeriian military is not very professional. They got up against a force that they felt they couldnt do anything with, and basically decided to save their own lives. Its a the act of a thirdworld country and the kind of military they have. Secretary of state john kerry took to social media today to talk about nigeria. Someone asked about the u. S. s efforts to help nigerias search and kerry tweeted this. What is he talking about sophisticated Counter Terrorism efforts . This is a good example of the u. S. s use of soft power. Learning what we did in iraq and afghanistan. The First Mission the military will do there is try to take down this boko haram network. Get its arms around it, and blanket the area with regards to communications. And the second thing will be an accessment of the situation, see what kind of military assets well see. For example, drones. Drones would be a tremendous resource to the nigeriian government. They could survey the land and report back. What about spy satellites . They are not fast enough . They wont give you that real time information. We have this capable to get in there real time, and fly 247. In the old days we might do that with pilots. What about the is there a National Conflict between, you know, who is running the operation . Obviously its in nigeria, if the United States comes in, what is the relationship there between the u. S. And the nigeriian military . I think the u. S. Has to be very careful not to get on in any way that suggest that there are boots on the ground. This is probably a facesaving operation for the president and government there. We cannot get involved with anything, because if we get a conflict down there, i think it could lead to really bad consequences what sort of capabilities do they have . Not much. Its not any level of professional military was lost long ago in a civil war, and now you see the situation you have, where they basically retreat in a situation where they failed to protect their own citizens. They dont have a lot of capabilities, we have to give this soft power to them and hopefully they will use it. Thank you very much. Yes. Coming up next the president goes shopping for support for his energy program. And italys former Prime Minister begins community service. What will he be doing . Before today no american president had ever been inside a walmart. President obama is the first. He visited a California Store today to push solar energy. He is using executive action bypassing congress to try to Lower Energy Costs and create at least 60,000 new jobs. We get more from mike viqueira. Its a another example of president obama going around congress to enact his agenda. The president announcing moves to promote solar energy. Among them, 2 billion to increase Energy Efficiency in federal buildings. Support for Training Programs at Community Colleges around the country. And new standards for electric motors. He is also encouraging the use of solar power in Public Housing where the federal government has a stake, and touting the increased use of solar in major american businesses like walmart. He spoke at a walmart where he hit republicans one more time. Unfortunately inside of washington we have still got some climate deniers who shout loud, but they are wasting everybodys time on seat l a settled debate. But he received some backlash, they say the low wages at walmart fly in the face of another one of his agendas. The white house promised back in august that they were going to put solar panels on the roof here of the white house. They produced a video to announce that those solar panels are now online. The 2000 president ial election between george w. Bush andal al gore eventually ended up at the Supreme Court. I asked david boys what he thought was at stake. The leader of the free world was at stake. And that was a pretty important decision and maybe more important than we realized at the time. I think in addition what was at stake was the way our democracy works, whether you are going to have Judicial Intervention to stop a vote count. Remember what happened here was that under florida law, people are entitled to a recount in a close election, and what happened here is the Supreme Court 5 to 4 stopped that recount. And they stopped the recount even before they had an argument. But they stopped the recount even before they had argument on the case, and one of the things that the majority judges said was we want to stop the recount because if the recount shows that Vice President gore is the winner, then that will undermine the legitimacy of george bushs presidency. Which obviously was true, but some would argue that also undermined the legitimacy of the electoral process. Join us for my conversation with david saturday 5 00 eastern time, 2 00 pacific. Times are still tough for many working class americans. Wages are stagnant especially for the youngest workers. Reporter brian has had no luck looking for a job. I have been looking very hard to find a job and i have put in so many applications at this point, and gotten virtually no responses. Reporter he now lives with his mother. I felt bad for him, you know. I have always raised him to be very independent. And its hard to do that if you cant support yourself. My mom has been wonderful. Without her support, i mean i might dare i say i may be homeless at this point. Because my mom has been so supportive. She has allowed me to stay here virtually rent free. Reporter he wonders and worries about the future. He has heard the prediction that millennials will be the first generation in u. S. History to do worse than their parents. While parts of the country have started to recover from the financial crisis, the sacramento area is not one of them, and continues to struggle with an Unemployment Rate higher than the national average. It floats between 8 to 9 here and for millennials, those between the ages of 18 and 31, its even worse. Almost 20 of them have no jobs in the sacramento region. And almost 40 now live with their parents. The damage with be permanent. For example, young people who enter the labor market during the recession have lower wages and higher Unemployment Rates. Reporter for the past two decades the labor markets here have trended apart from cities like san francisco, and the recession has made this difference more dramatic and more poignant. But the upside is that young people tend to be a mobile bunch, and they can easily relocate to a better labor market. So my suggestion is if you are a young person in a city like sacramento, look around. Consider moving to san francisco, the jobs here are plentiful, and your career will benefit in the long run. Reporter thats exactly what he decided to do. Apply for jobs in san francisco. And thats when we got the call, finally for a Job Interview in customer service, proving at least for him that there is better luck in the bay area.
