>> this is my selfie... what can you tell me about my future? >> ...can effect and surprise us... >> sharks like affection >> tech know, where technology meets humanity... only on al jazeera america i'm ali velshi. "on target" from tehran, iran. >> how much could nations possibly trust the united states? >> wild accusations against the united states. >> a comprehensive diplomatic solution. >> this solution will not change iran for the better. >> one of the most significant long term security problems that we've faced in a long time.

>> tonight, deals deadlines and distrust. the future of iran's nuclear ambitions are at stake, as well as the sanction he thas that haa devastating effect on iran. mary snow is in new york. mary. >> ali, mistrust fueled by people and parties not attending the negotiation in vienna. starting with ayatollah ali khamenei. he has warned the u.s. cannot be trusted and hopes the talks will succeed by demanding most sanction he be lifted before the infrastructure. and inspections of iranian military sites and he resumed out any freeze on iran's nuclear

enrichment. so-called framework that iran struck in early april. that agreement came one month after republicans led by house speaker john boehner made a dramatic show of their mistrust of a deal by allowing israeli prime minister benjamin netanyahu to speak in march. spoke for nearly an hour, announcing a bad deal, that iran would emerge with a clear path to the bomb. take a listen. >> this will not change iran for better. it will only change the middle east for worse. a deal that is supposed to prevent nuclear proliferation will only spark, not a farewell to arms, but a farewell to arms control. >> 47 republican senators signed

a letter written to leaders of the islamic republic of iran. could be reversed by the next president with the stroke of a pen. vice president biden slammed the letter as quote beneath the dignity of the senate. that brings us to today and reports that the nuclear talks led by secretary of state john kerry may go past their june 30th target date. some negotiators have deliberately decided not to set a new date to conclude negotiations. republican ed royce, chairman of the house foreign affairs committee said with the clock running out and quote, far reaching u.s. concessions in the workers a bad deal is looking fairly uncertain. let's go back to ali in tehran. ali is there optimism for a deal where you are? >> there is hope and signs have indicated for some people we

have spoken to in tehran. as we know, javad zarif has returned to tehran, there is speculation whether he will return to vienna tonight or in the morning, but speculation is that he win returning. to determine whether or not enough is going on there are other reports that indicate that the negotiations will go beyond the deadline which is 2:00 in the morning here tomorrow. midnight vienna time where those conversations are going on. now if they're close and they go beyond the zed lines the hope will continue. if the parties walk away, feeling that they haven't made up enough ground, then we have a problem on our hands. now here's the thing mary. the issue is the lats time they tried to get -- the last time they tried to get here they understood the various sides what they call the p-5 plus one and iran were relatively close

but not close enough to go to their home countries and get the necessary approvals. what we are talking about in iran, the necessary approval of the supreme leader. in the united states, the necessary approvals of congress. congress wanted the right to make changes to the agreement. be president obama said, congress is going to have the ability to say yes or no but not to negotiate things that fall within the purview of the cumulative succumulative,execut. some people are taking it as a good sign that the foreign minister has returned to iran with enough time to turn back around and go to vienna and finalize a deal. but the rest of the world has seen this before.

eeverybody is very prepared to walk away. so the feeling i've gotten from the people with whom i've spoken in the last few days that i've been here is cautious optimism. they're hoping for it. they've largely learned to live with these sanctions and if they had to continue they probably would be able to. but not -- i haven't spoken with a single person here in tehran at various levels who hasn't said that the best outcome would be a deal. what we aren't getting from people is whose fault it is that we're here in the first place and who should do what about it. are is but the idea that a deal that allows sanctions to be lipt e-lifted on iran is -- lifted on iran is something of great jubilation mary. >> i want to ask you about these sanctions l ali. you are on the ground, visited businesses. give us a sense of what the impacts of these sanction he are. >> that's what i've been

spending my entire time here doing. talking to business people, it means a lot of things. it means no access to global markets for the products that are made here for services that are offered. one thing you have to understand about tehran and you will once i get back is this is a modern society. this is a society where education levels are very high, business is conducted at a very high level, this is a modern city the city of tehran. they want to be able to trade with the rest of the world. they can't get foreign exchange. they can't sell their goods to the rest of the world. things as simple as persian rugs. i spent some time looking at beautiful art, wool and silk persian rugs. before the sanctions they were sending a 40 foot container per week to the united states, of these persian rugs. there has been no carpet shipped to the united states in over two years. a jeweler, people, like persian

rugs, they don't think about jewelry when they think about the value of their money. the value of the currency the reallye has dropped precipitously. they think americans and the rest of the world will come back. important to note mary: the key part of these sanctions is not just the ability to buy and sell things, it's banking sanctions, the inability to conduct transactions with the rest of the world. this is hurting this country. beyond all that this is a country that relies on oil revenues and those revenues have been cut by quite a bit in the last year. so iran is a country that is struggling economically and there is a widespread belief on the ground here that if some sort of deal is made, sanctions are lifted, the world does business with iran. the lot of regular people will improve, and prosperity will

prevail mary. >> all right ali thank you. when we're talking about deadlines there is a huge one in greece. later we'll come back and get your take on the financial drama unfolding in athens but stand by. first we'll go to vienna, austria, where u.s. and international negotiators have been meeting with iran. there may be a fatal flaw.

>> back in april u.s. and iranian negotiators banged out a preliminary zeal meant to find some milt ground-z deal meant to find some middle ground from tough sanctions. well this is the week when the fine print is supposed to be figured out. al jazeera correspondent james bays has our report from vienna austria where this final set of talks is set to go down.

james what do we expect? >> mary, one u.s. official described the atmosphere of these talks as a roller coaster. i think it's pretty fair to say that the last couple of hours has been a low tempo here, that's because most of the foreign minister with the exception of u.s. secretary of state john kerry have left. they have left because the iranian foreign minister zarif has left. the fact that he's gone back to tehran could make this the most important day of these whole talks because he's gone back for consultations with the president and the supreme leader. what clarifications is he trying oget from them? to get from them? i asked one expert who has been following these talks very closely. >> the exception was pushing across the red lines of the supreme leader of iran and he had to go back for consultations and see if there is any more flexibility that iran could show

at the negotiating table. the second possibility is there was a new proposal from the p-5 plus one that zarif didn't have instructions for and had to go back for consultations. and the third that is overlapping from the first two is the fact that both rouhani and zarif might feel compelled to have close consultations with the supreme leader so that they alone don't accept accountability for whatever the outcome here is. failure or success. >> everyone here agrees the talks will go past the deadline which was supposed to be tuesday. however tuesday will be an important day with the rival of the russian foreign minister sphrosergey lavrov and the retuf foreign minister zarif. >> breakout time, time required to produce enough weapons grade uranium for a nuclear weapon.

the bowms says under its plan -- obama administration says under its plan iran's breakout time will be one year compared to three months. university of texas at austin editor of nuclear terrorism and global security, the challenge of phasing out highly enriched uranium. allen thank you for joining us. >> thanks for having me. >> if vaughn only tw iran is one months away, why wouldn't that reduce the breakout time in your opinion? >> well, there are several very, very rosy assumptions in the obama administration's estimate. for example, they assume that iran would need 60 pounds of weapons grade uranium for a bomb. but experts have known for a a

long time that you only need half that amount. for a bomb of the size of hiroshima. in fact it appears iran would have many, many hundreds of kilograms of uranium in sold form which converted it to gas would give it a big big start to producing weapons grade uranium. so there are a number of factors in the administration's assumptions that are overly rosy. if you take realistic assumptions it looks like iran could credibly produce enough highly enriched uranium for a weapon in approximately three months. >> we'll get a little technical for a minute. if you are going to have a nuclear weapons program 5,000 centrifuges is the number you

need. but if you want a peaceful program you need a lot more. is there a danger that by limiting the number of sen industry fooudges yocentrifugesw the nuclear program? >> it's always been way too small for a nuclear power program but just exactly what you'd need to produce enough weapons grade uranium for a nuclear bomb. and unfortunately this pending deal and the details that have appeared in the media indicate that it would not. it would not significantly reduce iran's breakout time. so according to my calculations, the current breakout time is about two months. little under two months. and under the deal the breakout time would be about three months. so what we would get out of this deal on breakout time is it would extend it by just over one month. that's not very much. it really doesn't make any

difference whether iran can produce enough uranium for a bottom in two months or three months. there's really no difference in affecting our ability to react. in return, iran is going to get this extravaganza, tens of millions of dollars, first a signing bonus when they get their frozen assets unfrozen, that's 30 to 50 billion in one shot the estimates in wall street journal and then billions and billions of infusion into their economy. they get a lot, we get very little on breakout time. >> you said right there a deal with iran would be like signing in your words a $50 billion signing bonus right? when do current sanctions only serve to make the rest of the country or wouldn't they serve to make the rest of the country only more reliant on the existing leadership in iran?

>> no, i see it as exactly the opposite. right now iranian economy is in the tank. it's produced a lot of unhappiness amongst the iranian people and when they look for someone to blame, they blame the current leadership that's been there since the iranian revolution, these mul mullahs tt are in charge. that is very bad for the mullahs, that are in charge. by contrast under this deal if we were to award iran with tens of billions of dollars the economy is going to recover and the iranian people are going to give credit to the ruling regime, the mullahs. if you are going to do something to entrench the mullah, we should get something big in return and we haven't. >> president obama says this could strengthen the hand of moderate forces in iran. what do you say to that?

>> they're not ones who are in charge. i understand the argument that if you somehow engage that, they're going to understand our culture and they're going to embrace our culture. but the fact of the matter is, there's only one person in charge and that is ayatollah chakhamenei. we better get pretty good guarantees on nukes before we sign such a zeal. if we don't then congress should block the implementation by refusing to lift sanctions. >> allen cooperman thank you very much for joining us. up next, greece on the edge of financial chaos. greek banks are closed and little cash to go around. greece may be in debt but it could be america's problem, we'll explain when we come back.

>> the greek tragedy we've been talking about on this show for months is heading for a dramatic climax. it appears that greece will fail so pay 1.8 billion it owes to the imf on tuesday. greek prime minister alexis tsipras tried to assure citizens that their money and pensions were safe. negotiations over more bailout money focused on cut to pensions which tsipras declared too burdensome. after talks broke off, he called for a referendum to let greeks decide whether to accept the

>> john: terms. john what do you believe? >> endless cycle of debt, more oausterity. they also believe there will be no prospects for them in their personal lives, endorsed by creditors and now by the greek government. they won't be able to come out of university with their degrees, get paid in a satisfactory manner, be able to take out mortgages, stat new lives, have families, none of that is possible right now for a very, very large section of greek society, unless they've got money in the bank or help from their parents. yes vote on the other hand is

equally strong. would i say society is more or less equally divided it a now. the yes vote says if we pay no to this package, we cannot go back to creditors, and ask them for another arrangement, there is some goodwill left in european institutions and i think many people here in the yes camp feel that it really is the greeks turn to show their willingness to reach out and grasp that goodwill and reciprocate it . bringing this package on its own authority into parliament and have its parliamentary block vote on it has now, in effect, passed on that dilemma and therefore, the polarization comes with it at large. >> john what about the prospect

of become cut off from europe? >> greeks fiend very much the prior of europe right now. one way or the other this situation is going to move forward next sunday. if there's a no vote it will affirm the defacto position that greece will already northbound already. tomorrow on tuesday greece will in effect be in arrears on a 1.6 billion euro imf bond, which the greek government says it will not honor if it is not in an agreed financial situation with its creditors which it is not. and also next sunday you will have the expiry of that existing f assistance or program which also ends on tuesday. so when a no vote comes if that is indeed the result it will merely affirm that greece is

walking away from european financial institutions and into an unknown direction. presumably to fix its own problems on its own. >> john siropolous reporting from athens thank you very much very much. i want to go back to ali velshi in tehran, iran. be ali, what happens if greece fails to make its 1.8 billion payment to the imf on tuesday what happens ali? >> well first of all you and our viewers will have seen from market reactions in the united states that people are betting on the fact that for the first time in history, a fully developed nation will likely default. that is what we are starting to hear now. the rumblings of that greece will not make its payment. now remember, unlike the iran deadline in which they have until the last minute and say they're close, this was a technical deadline. greece was supposed to make the

payment at the middle of the month. they used a clause that nobody ever heard of and said you can pile up the payments and make it in the last day of the month. that means by midnight tomorrow they have got to have the payment to the international monetary fund, $1.8 billion. unlike in tehran, these are people sitting around a table that have a deadline. but the finance minister of greece has got to tell the bank of greece to wire the money. that means we're merely hours away from ability to make that paim. wpayment. we have heard it won't happen. lower markets throughout europe and the united states. that's where the uncertainty ends. no one has ever done this befo

before. zimbabwe has defaulted. argentina has defaulted. the fact that someone could default in the european union opens up all kinds of possibilities. greece has said they are holding a referendum next sunday. the europeans were very, very upset about that but angela merkel of germany has now said you noaa what if greece defaults and wants to reopen negotiations, we're open to that. what they don't want is a grexit, the unruly exit of greece. apart from that what does this mean? the flow out of the euro, into the dollar, the u.s. dollar will strengthen some more. fantastic for people on their way to europe for a vacation, really bad for u.s. manufactures or service providers who sell their goods, they are already suffering from a dollar that is too high. it will also suffer from people

buying bonds, causing the cost of those bonds to rise and the interest rate will drop. you could end up locking into a lower mortgage rate tomorrow as a result of a greek default. it will mean that anybody who needs to borrow money in greece, that was already a tough thing odo, i learned when i was there several weeks ak, it will become virtually impossible for business people, students, to get a loan. we'll learn more if it actually happens but we'll know by mid day eastern time tomorrow if greece has not instructed the bank of greece to wire the money. you've got to do it in the morning so it hits in the afternoon. as of now mary the speculation is that greece will not make its payment and become the first country, the first developed nation, to default to the imf. mary. >> all right ali velshi, thank you.

and as the world heads towards two enormous deadlines, ali velshi will be back tomorrow from tehran, iran with his exclusive story. i'm mary snow, thanks for joining us. >> greece waking up to a day of reckoning. the deadline to make good on a huge debt. what happens to the global economy if the country can't pay up? going into overtime... >> we are just working and it's too early to make any judgments on the brink of another deadline, this one for a final deal to curbing iran's nuclear power. the talks could rush out the
