Right now. Announcer from nbc news World Headquarters in new york this is nbc nightly news with lester holt. Good evening. First the deal now the sell. With todays historic agreement to curb Irans Nuclear program the Obama White House tonight is trying to convince nervous mideast neighbors and the American Congress that there is no better alternative. The u. S. And five other nations struck the deal with iran overnight, offering iran relief from economic sanctions in exchange for limits on Nuclear Production. But questions over compliance and verification along with irans history of provoking instability in the middle east are planting seeds of doubt in high places. We have full coverage tonight. We begin with our chief Foreign Affairs correspondent Andrea Mitchell from vienna. Andrea . Reporter good evening, lester. Well after years and decades in fact of calling each other the great satan and the axis of evil iran and the u. S. Are now entering uncharted territory. A diplomatic agreement to reduce irans suspected nuclear threat. John kerry and his iranian counterpart javad zarif weary but celebrating the deal to reduce Irans Nuclear capability in exchange for billions of dollars with the end of crippling sanctions. Years in the making it came together after 18 long days and nights of intense talks. Kerry even personally edited the final draft at 3 00 this morning after a midnight call vienna time to the president in the oval office. This deal offers an opportunity to move in a new direction. We should seize it. Reporter iran accepts limits on its Nuclear Production for ten years and on nuclear fuel and equipment for 15 years. Iran promises more access for u. N. Inspectors to suspect sites but with notice. But iran gets an economic lifeline hundreds of billions of dollars in sanctions relief. Once it meets those Nuclear Commitments perhaps by the end of the year. Reentry into the Global Banking system and five to eight years from now an end to the u. N. Arms and Ballistic Missiles embargo. So how do you justify down the road taking off the arms embargo on conventional weapons and Ballistic Missiles . The United States doesnt lose anything, andrea by giving them the opportunity to prove this is a peaceful program. Whats the alternative . Go to war now . You want to everybody want to say automatically lets bomb iran . I mean, is that the alternative . Reporter but the deal is a tough sell with critics in washington and tehran. As irans foreign minister acknowledges. A lot of mistrust in the ability and the intention of the United States to live up to this agreement and to try to implement its parts of the deal. So its going to be a difficult exercise. Reporter and in a call today president obama tried to reassure israels Prime Minister netanyahu. But sources say got nowhere. A landmark deal setting off a global debate that wont end anytime soon. Andrea mitchell nbc news vienna. Reporter im Richard Engel in israel where Prime MinisterBenjamin Netanyahu issued his first blistering statement almost as soon as the ink was dry. This is a bad mistake of stark proportions. Reporter netanyahu has been criticizing the deal in tweets in hebrew english, even farsi, the language of iran. But in tehran they werent listening. We did it we finally did it reporter nbcs ali arouzi is in the crowd tonight. Theres singing and dancing on the streets of tehran. You never see these things. People are overjoyed [ cheers ] reporter but in israel theres no faith the Iranian Regime can or will change. Deal or no deal. No wonder everybody in the streets celebrating. Because they got everything they wanted and the west got nothing at all. Reporter netanyahu said as far as israel is concerned the west just got the leading International Powers are betting our future on a deal with a formal sponsor of international terrorism. Reporter israelis worry theyll have to pay the price if this diplomatic gamble doesnt work. I think he made a big mistake. Obama made a big mistake. But no one can do nothing. He decided, and he was so determined in this mission. Reporter the Israeli Government couldnt stop the deal in vienna. But its hardly giving up. The next step is to use israels friends and supporters to spike the deal in washington. A retired general here in tel aviv told us israels next battle will be on capitol hill. Netanyahu is hoping republicans in congress will agree the deal gives away far too much. While israel has been by far the most vocal critic arab states especially saudi arabia are also skeptical. They worry that iran will cheat and that an emboldened tehran will just make the middle east even more chaotic. Lester . Richard engel in tel aviv tonight. Thank you. I want to turn to chuck todd nbc news political director and moderator of meet the press in our washington bureau. Chuck, how deep is the opposition in congress to this deal . Its pretty deep. Lester, it was really hard to find a republican either on the president ial campaign trail or on capitol hill to say anything nice about this deal at all. Most of them criticized it before even reading the deal. That said the Senate Republican leader Mitch Mcconnell admitted that congresss ability to actually block the implementation of the agreement is going to be very hard. And heres why. While congress has some oversight on what sanctions that the president can turn off, the Republicancontrolled Congress is going to try to do that try to reject the deal send it to the president. The president will veto that bill. Then theres going to be an attempt to override that veto. Now, heres what it will take. All the republicans plus 13 Senate Democrats and 44 House Democrats when you look at the numbers. In every conversation ive had today it is clear, lester that there is a hardcore 8 to 10 hawkish Senate Democrats who will vote with the republicans on this and try to kill this deal. But right now thats it. And the white house is making this argument to any other wavering democrats if congress derails the deal they argue the United States then would get the blame for having no more sanctions in place and allowing iran to pursue a nuclear program. Chuck, there are those who are already talking about this as a legacy item for the president , but we dont know how this legacy gets written, do we . We really dont. It make take ten years. The president himself today did an interview in the new york times, and he compared what he did with iran to nixon going to china. Well we didnt know whether nixon going to china was a good thing for almost two decades. We wont know for at least ten years. And that is the measurement being this. Will iran get the bomb . Chuck todd tonight. Thank you. Now to the wild weather pummeling several parts of the country. In kansas a giant ef3 tornado touched down last night, wind speeds up to 165 Miles Per Hour.

They should know later tonight. But already the mission is raising the profile of a little dwarf planet in ways previously unimaginable. It wasnt long ago scientists debated whether it was really even a planet. But suddenly new images like this have made pluto our tiniest and most distant of planetary neighbors a very big deal.
