State Department Certifies Iran's Compliance With Nuclear Deal | NPR

Jan 16, 2016:

The IAEA confirmed that Iran has complied with the requirements specified in the Iran Nuclear Deal.

President Obama issued an executive order entitled "Executive Order -- Revocation of Executive Orders 13574, 13590, 13622, and 13645 with Respect to Iran, Amendment of Executive Order 13628 with Respect to Iran, and Provision of Implementation Authorities for Aspects of Certain Statutory Sanctions" lifting some of the U.S. economic sanctions on Iran.

In addition, the U.S. and Iran performed a prisoner swap. Five Americans, including The Washington Post reporter Jason Rezaian were released by Iran. In exchange, the U.S. released seven Iranians and removed 14 others from international wanted lists.

In compliance with the Iran Nuclear Deal, Iran said it has removed the core of its Arak nuclear reactor. Now, IAEA inspectors will inspect to verify that the core has in fact been removed.

In addition, the number of centrifuges installed at the Fordow and Natanz enrichment sites have been significantly reduced over the past few months.

If the IAEA reports that Iran has in fact removed the core from the Arak reactor, then international sanctions against Iran will be lifted ("Implementation Day").

U.N. nuclear chief Yukiya Amano confirmed that samples taken at the Parchin nuclear facility in Iran were collected by Iranians and not by IAEA personnel. Amano stated that nonetheless, the sampling was done in accord with IAEA standards.

According to Deputy IAEA Director General Tero Varjoranta, it's not uncommon for the IAEA to have a country do its own sampling, and that the sampling is only one part of a comprehensive protocol to ensure a country is not cheating.

According to former IAEA Deputy Director General Olli Heinonen, Iran is a particularly sensitive case, and he knows of no other instance where a suspect country like Iran has been allowed to provide its own samplers.

Amano's visit, which included a meeting with Iranian President Hassan Rouhani, Iranian Foreign Affairs Minister Mohammad Zarif, and Ali Salehi who is head of Iran's nuclear agency, is part of an assessment due in December of this year which will help determine whether sanctions will be lifted on Iran, all part of the Iran nuclear deal.

Aug 7, 2015:

Yesterday, Charles (Chuck) Schumer, a Democratic senator from the state of New York, issued a press release entitled "My Position on the Iran Deal" in which, after careful analysis he opposes the Iran nuclear deal.

Chuck's concerns for the first 10 years of the deal can be summarized as follows:

• The 24 day inspection lead time (for undisclosed sites) "...would enable Iran to escape detection of any illicit building and improving of possible military dimensions (PMD) – the tools that go into building a bomb but don't emit radioactivity", and "the 24-day delay would hinder our ability to determine precisely what was being done at that site."
• The requirement of a majority of the 8-member Joint Commission needed to allow a site inspection, and how some of the members might be less-inclined to vote for a site inspection once they have resumed economic relations with Iran (with sanctions lifted)
• Because the "snapback" provisions can be applied unilaterally by each country in the deal, it's possible that some countries might invoke "snapback" and others not

Chuck's concerns for subsequent years of the deal can be summarized as follows:

• "After fifteen years of relief from sanctions, Iran would be stronger financially and better able to advance a robust nuclear program."
• "...the agreement would allow Iran, after ten to fifteen years, to be a nuclear threshold state with the blessing of the world community."
• "Iran would have a green light to be as close, if not closer to possessing a nuclear weapon than it is today."
• "...the ability to thwart Iran if it is intent on becoming a nuclear power would have less moral and economic force."
• The negative consequences of the lifting of sanctions (allows Iran to use some of the funds to support military and terrorist actions in the Middle East, and could also be used to acquire ICBM missiles when the 8-year embargo period has expired)
• "Iran would have a green light to be as close, if not closer to possessing a nuclear weapon than it is today."

In summary, Chuck said:

• "To me, the very real risk that Iran will not moderate and will, instead, use the agreement to pursue its nefarious goals is too great."
• "...I will vote to disapprove the agreement, not because I believe war is a viable or desirable option, nor to challenge the path of diplomacy. It is because I believe Iran will not change, and under this agreement it will be able to achieve its dual goals of eliminating sanctions while ultimately retaining its nuclear and non-nuclear power. Better to keep U.S. sanctions in place, strengthen them, enforce secondary sanctions on other nations, and pursue the hard-trodden path of diplomacy once more, difficult as it may be."

Here are a few quotes from Kerry's testimony:

Iran has agreed to refrain from producing or acquiring highly enriched uranium and weapons-grade plutonium for nuclear weapons forever.

And when it comes to verification and monitoring, there is absolutely no sunset in this agreement – not in 10 years, not in 15 years, not in 20 years, not in 25 years. No sunset ever.

Now to be clear, if Congress rejects what was agreed to in Vienna, you will not only be rejecting every one of the restrictions that we put in place – and by the way, nobody's counting the two years that Iran has already complied with the interim agreement, and by the way complied completely and totally, so that we've already rolled their program back. We've reduced their 20 percent enriched uranium to zero. That's already been accomplished. But if this is rejected, we go back to their ability to move down that road. You'll not only be giving Iran a free pass to double the pace of its uranium enrichment, to build a heavy water reactor, to install new and more efficient centrifuges, but they will do it all without the unprecedented inspection and transparency measures that we have secured. Everything that we have tried to prevent will now happen.

Jul 15, 2015:

President Obama held a press conference (which ran over an hour) where he discussed and defended the Iran nuclear deal and answered questions from the press.

Here are some of Obama's key points from the press conference:

With this deal, we cut off every single one of Iran's pathways to a nuclear program -- a nuclear weapons program, and Iran's nuclear program will be under severe limits for many years. Without a deal, those pathways remain open; there would be no limits on Iran's nuclear program, and Iran could move closer to a nuclear bomb.

With this deal, we gain unprecedented, around-the-clock monitoring of Iran's key nuclear facilities and the most comprehensive and intrusive inspection and verification regime ever negotiated. Without a deal, those inspections go away, and we lose the ability to closely monitor Iran's program and detect any covert nuclear weapons program.

With this deal, if Iran violates its commitments, there will be real consequences. Nuclear-related sanctions that have helped to cripple the Iranian economy will snap back into place. Without a deal, the international sanctions regime will unravel, with little ability to re-impose them.

With this deal, we have the possibility of peacefully resolving a major threat to regional and international security. Without a deal, we risk even more war in the Middle East, and other countries in the region would feel compelled to pursue their own nuclear programs, threatening a nuclear arms race in the most volatile region in the world.

But the bottom line is this: This nuclear deal meets the national security interests of the United States and our allies. It prevents the most serious threat -- Iran obtaining a nuclear weapon, which would only make the other problems that Iran may cause even worse. That's why this deal makes our country, and the world, safer and more secure. It's why the alternative -- no limits on Iran's nuclear program, no inspections, an Iran that's closer to a nuclear weapon, the risk of a regional nuclear arms race and a greater risk of war -- all that would endanger our security.

So when this deal gets implemented, we know that we will have dismantled the immediate concerns around Iran's nuclear program. We will have brought their stockpiles down to 98 percent. We will have significantly reduced the number of centrifuges that they operate. We will have installed an unprecedented inspections regime, and that will remain in place not just for 10 years but, for example, on the stockpiles, will continue to 15 years.

Iran will have pledged to the international community that it will not develop a nuclear weapon and now will be subject to an Additional Protocol, a more vigorous inspection and monitoring regime that lasts in perpetuity. We will have disabled a facility like Arak, the Arak facility, from allowing Iran to develop plutonium that could be used for a bomb. We will have greatly reduced the stockpile of uranium that's enriched. And we will have put in place inspections along the entire supply chain so that if uranium was diverted into a covert program we would catch it.

So I can say with confidence but, more importantly, nuclear experts can say with confidence that Iran will not be in a position to develop a nuclear bomb. We will have met our number-one priority.

And for all the objections of Prime Minister Netanyahu, or, for that matter, some of the Republican leadership that's already spoken, none of them have presented to me, or the American people, a better alternative.

I'm hearing a lot of talking points being repeated about "this is a bad deal" -- "this is a historically bad deal," "this will threaten Israel and threaten the world and threaten the United States." I mean, there's been a lot of that.

What I haven't heard is, what is your preferred alternative? If 99 percent of the world community and the majority of nuclear experts look at this thing and they say, this will prevent Iran from getting a nuclear bomb, and you are arguing either that it does not, or that even if it does it's temporary, or that because they're going to get a windfall of their accounts being unfrozen that they'll cause more problems, then you should have some alternative to present. And I haven't heard that. And the reason is because there really are only two alternatives here: Either the issue of Iran obtaining a nuclear weapon is resolved diplomatically through a negotiation, or it's resolved through force, through war. Those are the options.

So to go back to Congress, I challenge those who are objecting to this agreement, number one, to read the agreement before they comment on it; number two, to explain specifically where it is that they think this agreement does not prevent Iran from getting a nuclear weapon, and why they're right and people like Ernie Moniz, who is an MIT nuclear physicist and an expert in these issues, is wrong, why the rest of the world is wrong, and then present an alternative.

So let's take the issue of 24 days. This has been I think swirling today, the notion that this is insufficient in terms of inspections. Now, keep in mind, first of all, that we'll have 24/7 inspections of declared nuclear facilities -- Fordow, Natanz, Arak, their uranium mines; facilities that are known to produce centrifuges, parts. That entire infrastructure that we know about we will have sophisticated, 24/7 monitoring of those facilities.

So then the issue is, what if they try to develop a covert program? Now, one of the advantages of having inspections across the entire production chain is that it makes it very difficult to set up a covert program. There are only so many uranium mines in Iran. And if, in fact, we're counting the amount of uranium that's being mined and suddenly some is missing on the back end, they got some explaining to do.

But let's say that Iran is so determined that it now wants to operate covertly. The IAEA, the international organization charged with implementing the non-proliferation treaty and monitoring nuclear activities in countries around the world -- the IAEA will have the ability to say, that undeclared site we're concerned about, we see something suspicious. And they will be able to say to Iran, we want to go inspect that.

As for the fact that it may take 24 days to finally get access to the site, the nature of nuclear programs and facilities is such, this is not something you hide in a closet. This is not something you put on a dolly and kind of wheel off somewhere.

Is it possible that Iran decides to try to cheat despite having this entire inspection verification mechanism? It's possible. But if it does, first of all, we've built in a one-year breakout time, which gives us a year to respond forcefully. And we've built in a snap-back provision so we don't have to go through lengthy negotiations at the U.N. to put the sanctions right back in place.

Regarding the existing Iran embargo on the import and export of ballistic missiles and conventional arms, Obama said:

• there are other mechanisms in place under international law, including U.N. resolutions that allow the United States to intercept and prevent arms shipments by Iran
• the sanctions which will be lifted in the Iran nuclear deal include the embargo (the embargo was part of the sanctions when they were initially put in place), so when the sanctions are lifted the embargo will be lifted as well
• because Iran has breached trust in the past, Obama pressed negotiators to include an extension of the embargo

When asked by a reporter if the inflow of money into Iran as a result of lifting sanctions in the Iran nuclear deal will mean just more money for Iran's terrorist activities (and not be spent to improve the economic conditions in Iran), the President responded:

Do we think that with the sanctions coming down, that Iran will have some additional resources for its military and for some of the activities in the region that are a threat to us and a threat to our allies? I think that is a likelihood that they've got some additional resources. Do I think it's a game-changer for them? No.

They are currently supporting Hezbollah, and there is a ceiling -- a pace at which they could support Hezbollah even more, particularly in the chaos that's taking place in Syria. So can they potentially try to get more assistance there? Yes. Should we put more resources into blocking them from getting that assistance to Hezbollah? Yes. Is the incremental additional money that they've got to try to destabilize the region or send to their proxies, is that more important than preventing Iran from getting a nuclear weapon? No. So I think -- again, this is a matter of us making a determination of what is our priority.

Obama said that if the Iran nuclear deal was not made, current sanctions would not have the same "vigor and effectiveness" because our allies in the deal would lift their sanctions, leaving only sanctions from the United States still in place. The reasons this would happen are because:

• the U.S. walked away from a deal which our allies endorsed
• our allies initially chose to agree to sanctions along with the U.S. because the U.S. was sincerely trying to broker a peaceful deal with Iran on their nuclear program
• our allies have been hurt economically from the sanctions (for example, the inability to buy oil from Iran)

Regarding the argument that at the 10-year mark (when some of the deal provisions expire) Iran could resume it's ambitions, in addition to mentioning the fact that Iran is a part of the Non-Proliferation Treaty, Obama said:

So even if everything the critics were saying was true -- that at the end of 10 years, or 12 years, or 15 years, Iran now is in a position to decide it wants a nuclear weapon, that they're at a breakout point -- they won't be at a breakout point that is more dangerous than the breakout point they're in right now. They won't be at a breakout point that is shorter than the one that exists today. And so why wouldn't we at least make sure that for the next 10, 15, years they are not getting a nuclear weapon and we can verify it; and afterwards, if they decide if they've changed their mind, we are then much more knowledgeable about what their capabilities are, much more knowledgeable about what their program is, and still in a position to take whatever actions we would take today?

When asked by a reporter "So none of this is holding out hope that they'll change their behavior?", Obama responded:

No...I'm not banking on that to say that this deal is the right thing to do.

Obama ended the press conference with the following:

Again, it is incumbent on the critics of this deal to explain how an American President is in a worse position 12, 13, 14, 15 years from now if, in fact, at that point Iran says we're going to pull out of the NPT, kick out inspectors and go for a nuclear bomb. If that happens, that President will be in a better position than what happened if Iran, as a consequence of Congress rejecting this deal, decides that's it, we're done negotiating, we're going after a bomb right now. The choices would be tougher today than they would be for that President 15 years from now. And I have not yet heard logic that refutes that.

After 20 months of meetings and negotiations, The United States, along with the United Kingdom, France, China, Russia, Germany (the P5+1), and the European Union reached a nuclear arms deal with Iran. The U.S. Congress has 60 days to review the deal with the option of putting together legislation to block the deal, which President Obama already said he would veto. That means it would take a two-thirds vote in Congress to override a presidential veto.

A 109-page document entitled Joint Comprehensive Plan of Action (JCPOA) describes the details of the deal which in general is for 10 years. Here's a summary:

• International Atomic Energy Agency (IAEA) inspections at all Iranian enrichment sites and centrifuge production and storage sites, with a 24-day inspection request response time frame for undeclared facilities and 24/7 inspections of declared nuclear facilities (Fordow, Natanz, and Arak) and their uranium mines (some provisions of the inspections will last 20-25 years, and some are permanent)
• Existing supplies of low enriched uranium in Iran must be reduced by 98 percent
• Existing numbers of centrifuges in Iran must be reduced by two-thirds
• After 15 years there are no limits on how much nuclear fuel Iran can produce
• After the eighth year, Iran can conduct research on advanced centrifuges
• Existing sanctions on Iran will be lifted (possibly by the end of this year), but a "snapback" provision will reinstate sanctions if a panel of nations determines that Iran has violated any part of the deal
• The current Iran embargo on the import and export of ballistic missiles will be lifted in no more than eight years, possibly sooner if IEAA inspections show that Iran is in fact creating nuclear fuel for peaceful purposes only
• The current Iran embargo on the import and export of conventional arms will be lifted in no more than five years, possibly sooner if IEAA inspections show that Iran is in fact creating nuclear fuel for peaceful purposes only

In an interview with CNN's Christiane Amanpour Kerry stated that during the George W. Bush administration, Iran's inventory of centrifuges increased from 164 to 19,000, and that Iran had generated enough fissile material to build 10 bombs. His point is that the sanctions that have been in place for many years have not prevented Iran from making significant progress toward a nuclear weapon. He also stated that sanctions have done what they were intended to do which is to bring Iran to the negotiating table.

Apr 15, 2015:

The U.S. State Department issued a media note entitled "Parameters for a Joint Comprehensive Plan of Action Regarding the Islamic Republic of Iran's Nuclear Program" which outlines the specifics the U.S. is striving for in the deal.

One of the terms used in the details of the Iran nuclear deal is "breakout time". "Breakout time" is the amount of time it would take Iran to make enough material for one nuclear bomb if Iran decided to completely abandon the agreed upon deal and create a bomb as fast as possible.

Commentary:

From what I've read, it takes two things to build a nuclear bomb: a certain threshold amount of enriched uranium and a lot of centrifuges. According to The Historic Deal that Will Prevent Iran from Acquiring a Nuclear Weapon on The White House website:

Currently, Iran has a uranium stockpile to create 8 to ten nuclear bombs.

Right now, Iran has nearly 20,000 centrifuges between their Natanz and Fordow facilities.

Assuming these facts and figures are correct, Iran has vastly increased the amount of raw materials needed to build a nuclear bomb over the past 10-15 years despite sanctions (read a transcript of John Kerry's remarks in a CNN interview with Christiane Amanpour here where he talks about this). In other words, sanctions, while they may have slowed the process, have not prevented Iran from significantly advancing its ambition to obtain a nuclear bomb.

If we do nothing ("no deal is better than a bad deal") and scrap the Iran nuclear deal, then Iran continues to get closer and closer to a nuclear bomb, and based on the facts and figures Iran is very close right now.

There is no "magic solution" that will absolutely, positively prevent Iran from getting a nuclear bomb, including the Iran nuclear deal. If Iran wants a bomb, Iran will get a bomb, even with the nuclear deal in place.

Regarding the argument that the lifting of sanctions gives Iran much more money with which to pursue it's nefarious intentions (and pass some of that money on to other terrorist groups like Hezbollah and Hamas), I think that is a valid concern, and in an ideal Universe it's something we certainly prefer not to do. But, like President Obama, I think the threat of a nuclear bomb is greater than the threat posed by an influx of funds. Keep in mind that because the Iran nuclear deal was put together by a coalition of the world's super-powers, if Iran decides to bail on the deal in the future, they would be putting themselves at a great disadvantage and would likely be up against not only the United States but all the countries who negotiated the deal.

Like President Obama, the only other way I can see to prevent Iran from getting a nuclear bomb is by force - in other words, war. The consequences of going to war with Iran could be catastrophic, could touch off a firestorm in the Middle East, and would surely be denounced by our allies that helped negotiate the Iran nuclear deal, so I don't see that as a good alternative.
