"nightly news" begins now. from nbc news world headquarters in new york, this

is "nbc nightly news" with brian williams. good evening. the question was raised at the pentagon today at the very top, the secretary of defense, if this terrorist group isis is capable of what we have seen so far, the rampant violence and gruesome killings, most recently the awful execution of an american journalist carried out on camera, then what risk does isis perhaps pose to the united states? the answer from the boss at the pentagon today indicates it's a question the u.s. is concerned about. and in a violent world for good reason. it's where we begin tonight with white house correspondent kristen welker traveling with the vacationing president tonight in martha's vineyard. kristen, good evening. >> reporter: brian, good evening. today the secretary of defense spoke to reporters for the first time since james foley was executed. and he didn't mince his words about the immediate threat that isis poses. the secretary of defense acknowledged today what armies

in syria and iraq already knew, isis is a force to be reckoned with. >> they're beyond just a terrorist group. they marry ideology, a sophistication of strategic and tactical military prowess. >> reporter: and they force the pentagon to react. >> oh, this is beyond anything that we've seen. so we must prepare for everything. and the only way you do that is you take a cold steely hard look at it and get ready. >> reporter: it's not just on the battlefield, the isis pr machine is sophisticated. its technology up-to-date. videos to instill fear, a tweet taunting the president with a photo of an isis flag in the shadow of the white house. and most recently the video of james foley's execution on youtube prompting fear that fol foley's death is only the beginning. >> i don't think we've seen a significant threat to american security since the early days of

9/11. >> reporter: increasing -- the president developed a defiant tone. >> the united states of america will continue to do what we must do to protect our people. >> reporter: but after those remarks mr. obama went back to balancing vacation with work as some critics questioned whether he should have cut his vacation short. and while the white house continued to rule out boots on the ground, the state department wants 300 more security personnel in baghdad. and air strikes were increased after foley was killed. >> clearly if we're going to use military action to fight these folks, it's going to have to be more aggressive than what we've done heretofor. >> reporter: polls consistently show majority of americans oppose u.s. intervention militarily. still, isis has changed the calculus for the president. >> mr. obama i think he realized he can't use this narrative any longer how he's ending two wars on his watch. and we're going to have to settle in for a long effort. >> reporter: the joint chiefs

chairman general martin dempsey had a blunt assessment of what it would take to defeat isis. he said the u.s. and its allies would have to attack the terrorist group on syrian soil. a senior administration official told me this afternoon the president is weighing a range of options, but there are no immediate plans to go that far. brian. >> kristen welker covering the vacationing president tonight, martha's vineyard, massachusetts. kristen, thanks. also tonight we are learning more about that failed u.s. rescue attempt to try to save james foley and other americans being held by isis. and we're hearing from a man once held captive alongside him. our chief foreign correspondent richard eng l is live tonight on the turkey/syria border for us. richard, good evening. >> reporter: good evening, brian. u.s. commandos tell us that the rescue mission was one of the most risky operations they've ever tried to carry out. and now we're learning new details about what happened and why. isis shocked the world and washington when its fighters

rampaged through the city of mosul in northern iraq last june. isis, the world's most brutal terrorist group had broken out of syria pouring into iraq. u.s. military officials expected american air strikes against isis would be coming soon and that isis would likely take its revenge on its american hostages, at least four of them including reporter james foley. the president authorized a rescue mission. the white house said the hostages were in danger with each passing day in custody. in early july with an unspecified number of u.s. war planes providing cover, radar resistant helicopters crossed into syrian air space. they headed north of the city of the isis stronghold landing by an oil refinery. delta force commandos killed several isis fighters in a gunfight. but the hostages were gone. the military had just missed

them officials say. the u.s. began air strikes making it far more dangerous for the hostages. french reporter hanin released in april shared a cell with foley. for a week he says they were handcuffed together. >> he was my main cell mate during our recent captivity together. he was just great. he was always supporting everyone. always there to help. and to share. >> reporter: isis executed james foley saying it was revenge for the u.s. air strikes in iraq and threatened to kill another american reporter unless the air strikes stop. and, brian, just a week before foley was executed his family received an e-mail. it was from isis. it was full of rage. and it said foley would pay the price for those air strikes. brian. >> richard engel along the turkish border for us tonight.

thanks. late today we learned from the pope, the vatican talled the foley family to offer comfort, consolation and prayers. the vatican says the family was deeply moved and grateful for his call and kindness. the family will speak about their son tomorrow morning on "today." in atlanta today something a lot of people never thought they'd see, an american doctor once near death from ebola. the man we all watched as he was flown back to this country. today he walked out of the hospital isolation unit and told his own story for the first time. our report tonight from nbc's gabe gutierrez in atlanta. >> today is a miraculous day. i am thrilled to be alive, to be well and to be reunited with my family. >> reporter: dr. kent brantly discharged today from emory university hospital nearly three weeks after walking into an isolation unit gravely ill with the ebola virus he contracted

while treating patients in liberia. he says he got sick right after sending his family home to protect them. >> as i lie in my bed in liberia for the following nine days getting sicker and weaker each day, i prayed that god would help me be faithful even in my illness. i did not know then but have learned since that there were thousands, maybe even millions of people around the world praying for me throughout that week and even still today. i cannot thank you enough for your prayers and your support. >> reporter: we also learned today the other missionary diagnosed with ebola, nancy writebol, was quietly discharged on tuesday and is now spending time with her husband. the cdc and emory physicians say these patients no longer have the ebola virus in their blood and pose no health risk. both have been given doses of an experimental drug. the survivors and their doctors are now urging the world to turn its attention to the outbreak in west africa where ebola has infected some 2,500 people,

killing more than 1,300. in liberia neighborhoods are now blocked off to prevent the disease from spreading, causing violent clashes between desperate residents and police. how dire is the situation over there? >> we spoke via skype with american dr. dan kelly in sierra leone. >> what we really need is people to get on a plane like they did for haiti and really support us out here. >> reporter: back in the u.s. dr. brantly hugged the physicians and nurses responsible for his care. the first ebola patient ever treated on american soil, now a survivor. gabe gutierrez, nbc news, atlanta. the situation in ferguson, missouri, got a big assist from mother nature last night. it rained. and a line of thunderstorms and downpours served to keep a lot of people off the streets. the tensions are showing some slow signs of easing, enough so that the governor of the state has ordered the national guard

to leave town. and tonight we're learning more about the officer involved in the shooting that started it all. nbc's ron allen remains in ferguson for us again tonight. >> reporter: missouri's national guard is pulling out. brought in by the governor earlier this week to protect the police command post after violent protests and confrontations. they're withdrawing after two straight nights of calm. few arrests, small crowds. many here reassured justice will prevail after attorney general eric holder's visit. he promised a thorough investigation into whether officer darren wilson violated michael brown's civil rights when the teenager was shot and killed. >> i've seen a lot in my time as attorney general, but few things have affected me as greatly as my visit to ferguson. >> reporter: police have claimed wilson was assaulted before the shooting. today, a senior official familiar with the investigation told nbc news wilson was taken to a hospital for treatment. now attention turns to the grand jury proceeding. >> how dare you tell me i can't

go up -- >> reporter: protesters tried to present 70,000 petition signatures calling for the removal of prosecutor robert mcculloch. his critics claim he's biased toward police. his mother and numerous relatives work for the police. his father, a police officer, was killed in the line of duty. >> may be a very fierce advocate for victims of violence, regardless of the circumstances, regardless of their status in life. >> reporter: also today ferguson's determination to win. high school football team back on the field. but schools here still closed because of the unrest. the nfl st. louis rams opened up their practice field. >> there's strength in community. and when people come together, everything's possible. >> reporter: the season kicks off friday night. michael brown's high school team will hold a moment of silence before their game on monday. the hope here of course is that everyone in this community comes together and roots for the home team.

brian. >> ron allen tonight as the national guard pulling out of ferguson, missouri behind him there. ron, thanks. there was news today regarding the huge summer trend that has rocked the charity world and chilled many a spine. new figures out today show it's raised at least $42 million for lou gehrig's disease. but today the united states reminded its diplomats they are officially barred from taking part, as are members of congress, because they're not allowed to use public office for private gain no matter how good the cause. also today it turned mighty serious in campbellsville, kentucky, when two firefighters were injured, one of them critically. they were just trying to help a group of students take part. their aerial ladder got too close to live power lines while it was being put up. beyond the two firefighters who took and survived the jolt of current, power was knocked out across a huge area. none of the participating

students was injured. still ahead for us on a thursday night, the astonishing view showing the scale of devastation from the history making drought emergency. it's crippled one of the largest single water supplies in our country as cities and towns run dry. and later, a close encounter at the aquarium. a remarkable surprise caught on camera. setting up the perfect wedding day begins with arthritis pain and two pills. afternoon arrives and feeling good, but her knee pain returns... that's two more pills. the evening's event brings laughter, joy, and more pain... when jamie says... what's that like six pills today? yeah... i can take 2 aleve for all day relief. really, and... and that's it. this is kathleen... for my arthritis pain, i now choose aleve. get all day arthritis pain relief with an easy-open cap.

a new study out tonight from researchers at the university of san diego estimates that 63 trillion gallons of ground water have been lost since the beginning of just last year in this history making drought in the american west. tonight, we're going to show you how this emergency is causing a popular landmark vacation spot to quite literally disappear before our eyes while drying up a major source of water for several states. our report tonight from nbc's harry smith. >> reporter: lake meade, take water as blue at the caribbean and place it in the mountains of

the desert southwest and you have the largest reservoir in america. but it doesn't take long to notice what locals call the bathtub ring, the line that shows how high the water used to be. just to illustrate how far the water has dropped, that red triangle up on a hill up there, that's a navigational marker. we're more than 100 feet below that. fourteen years of drought have lake meade at its lowest level since the hoover dam was built in the 1930s. and if the drought continues, there's a good chance big water consumers like california will find its supply rationed. and a low water level has meant moving marinas, sometimes hundreds of yards. the adjustment isn't always pretty. but out on the lake it's very much business as usual. nick marietta pilots his 75-foot houseboat as far from civilization as possible. >> your phone quits working in

about three minutes and it just gets better. >> reporter: nick and his friends spend almost every weekend on lake meade. he says they've grown accustom to the lake's ups and downs. >> must feel like you're on a yo yo. >> sometimes it goes down so fast you can almost feel it. >> reporter: while the lake is down there's been above average moisture this year upstream in colorado. in the fall they expect lake meade to go up some, but just some. what's your best day out here? >> about a five-mile-an-hour wind, a hundred degrees, barbecue, have fun, all of our friends just have a ball. >> reporter: and that's really the message lake meade lovers want to pass along. the lake is not what it once was, but they're more than happy to make the best of what's left. harry smith, nbc news, lake meade. and we're back in a moment with what we're learning tonight about sleep, specifically who's getting the most of it and a big surprise about the city that never sleeps.
