Biden versus Iranian nuclear blackmail

 

Iran’s recent rebuff of US President Joe Biden’s offer to commence talks on getting both Washington and Teheran back into compliance with the Iran nuclear deal has, at least temporarily, thrown a spanner into Biden’s strategy for quickly reversing Iran’s relentless march away from the restrictions of the 2015 agreement – formally known as the Joint Comprehensive Plan of Action (JCPOA). 

While efforts to get Iran to the negotiating table will no doubt continue in the coming weeks, it’s long past time for the United States to start thinking seriously about what it will do to contain Iran’s expanding nuclear program in the meantime. How long is the United States prepared to simply stand by and watch as Iran continues, month after month, to ratchet up its nuclear activities, inching ever closer to some kind of threshold nuclear weapons capability?

In response to the Trump Administration’s withdrawal from the JCPOA and reimposition of draconian sanctions, Iran has been engaged since the summer of 2019 in a steady, sustained campaign to violate the JCPOA’s constraints. Taken individually, each breach can appear incremental and not overly concerning. But taken together, cumulatively, they paint an increasingly alarming picture.

As detailed in a recent report by the Institute for Science and International Security, Iran’s stockpile of low-enriched uranium (below 5% concentration of uranium-235) is now 14 times greater than the JCPOA’s limits. If further enriched closer to 90% purity, that might already be enough for up to three nuclear bombs. Iran’s breakout estimate – defined as the time required to enrich enough weapons-grade uranium for its first nuclear device – has dropped from one year under the JCPOA to potentially as low as 2.7 months today. 

For more than a year, Iran has been enriching uranium to 4.5%, breaching the nuclear deal’s limits of 3.67%. But beginning in early January, it took a qualitative leap forward by resuming enrichment to 20% at Fordow – a facility built deep inside a mountain that Iran kept hidden from the world until it was exposed by the United States in 2009, and where the JCPOA had banned all enrichment until 2030. As a technical matter, enriching uranium to 20% represents 90% of the work required to produce weapons-grade material.

Iran is also significantly increasing its enrichment capacity. For months, it has been conducting research and development on up to nine different models of advanced centrifuges and in numbers that far exceed the JCPOA’s limits – gaining new knowledge and expertise that no return to the JCPOA can now reverse. 

Perhaps more worryingly, Iran has recently begun to deploy hundreds of these advanced centrifuges in cascades at its two main enrichment facilities, Natanz and Fordow. Some are already operational. These second and third-generation centrifuges are anywhere from three to seven times more efficient than the older models permitted under the JCPOA, allowing them to produce far larger quantities of enriched uranium in a much shorter timeframe. Once their installation is complete, Iran’s enrichment capacity will be almost three times larger than the JCPOA cap.

Another hugely provocative step recently taken by Iran, again in flagrant violation of the JCPOA, was its decision to begin producing uranium metal – one of whose uses can be forming the core of a nuclear weapon. The United Kingdom, France, and Germany, the JCPOA’s European participants known as the EU-3, said they were “deeply concerned” since the move had “no credible civilian use” and carried “potentially grave military implications.” 

Also of profound concern was steps Iran took in February to drastically curtail inspections by the International Atomic Energy Agency (IAEA). A far more acute crisis was averted only when Rafael Grossi, the agency’s Director-General, rushed to Teheran to negotiate a last-minute understanding that, at least temporarily, averted a situation that in his words “would not have been reversible or recoverable” in terms of non-proliferation, and where the IAEA “would basically be flying blind without any idea what would be taking place in terms of enrichment activities.”

Grossi said that the arrangement gave the IAEA “the minimum that it needs” to conduct necessary verification and monitoring activities, but only for a period of up to three months and only if, in the interim, the United States grants large-scale sanctions relief to Iran. If that doesn’t happen, Grossi acknowledged, Iran is threatening to destroy critical monitoring data being gathered through technical means on its nuclear activities, rather than providing the information to inspectors.

The IAEA is also in a significant conflict with Iran over several sites that were once linked to Iran’s secret nuclear weapons program. In violation of Iran’s obligations under the Nuclear Non-Proliferation Treaty (NPT), none of the sites were ever declared to the IAEA. All of them have subsequently been razed and sanitised as part of a massive concealment effort. Much information about the sites only became known as the result of an archive of nuclear weapons documentation that Israeli intelligence miraculously spirited out of Teheran in 2018. 

After much Iranian stonewalling, the IAEA gained access to four of the sites over the course of 2019 and 2020 and found evidence of man-made uranium particles at three of them. Pressed to explain why, Iran’s answers to the IAEA have so far ranged from “not technically credible” to unresponsive. The bottom line: in addition to the alarming expansion in Iran’s declared nuclear program, there is now strong reason to suspect that Iran is concealing from the world undeclared nuclear material once linked to its clandestine nuclear weapons effort. 

Put it all together and it’s clear that the situation is getting very dangerous. And there’s a strong chance that it will get worse still. 

For its part, the Biden Administration hoped it would be able to stem the brewing crisis by rapidly negotiating a return to the JCPOA. That clearly hasn’t happened. But even if a negotiation gets going, it’s increasingly clear that it will likely be a much more complicated, messy, and drawn-out process than many JCPOA supporters anticipated. So, the question emerges: What does the United States do while waiting for a return to the JCPOA? How much further is it prepared to let the Iranians go in pushing the nuclear envelope? 

Of course, it should be underscored that the vast majority of Iran’s JCPOA violations occurred during Donald Trump’s final 19 months in office, including the move to 20% enrichment. Trump threatened upon abandoning the JCPOA in 2018 that Iran “would face very severe consequences” if it responded by restarting its nuclear program. But when Iran actually called his bluff repeatedly, Trump did little about it. The only tool in his kit bag was unilateral sanctions and when a barrage of designations unprecedented in US history – around 1,000 Iranian entities were ultimately targeted during Trump’s single term – did nothing to slow the methodical growth of Iran’s enrichment efforts, the Administration had no answer, no plan B.

For its part, Israel had a far more serious approach to the alarming uptick in Iran’s nuclear activities. Not only did its intelligence services pilfer the nuclear archive, but they allegedly were also the hand behind the audacious destruction last July of an above-ground factory for the mass assembly of advanced centrifuges, as well as the assassination of the scientific mastermind behind Iran’s nuclear weapons program in November. But all to very uncertain effect. Indeed, Iran is now rapidly building a new centrifuge factory, this time deep inside a mountain, while the assassination triggered Iran’s parliament to pass a law that actually accelerated the regime’s JCPOA violations.

 

One approach for limiting Iran’s further nuclear expansion that the United States has yet to consider, but needs to start, is setting some clear red lines that, if crossed, would trigger a far more punishing response against Iranian interests. Last June, I suggested that those lines might be drawn at Iran starting to enrich again to 20% or significantly curtailing IAEA inspections. Obviously, no such messages were delivered and seven months later, Iran has blown through each of those thresholds with impunity.

Of course, there’s no way to prove that Iran wouldn’t have done so even if the red lines had been established. But as I noted in my article, there is strong precedent for suspecting that the regime might take such limits quite seriously. Though heavily derided at the time, in a 2012 speech at the United Nations, Israeli Prime Minister Binyamin Netanyahu literally drew a red line on a cartoon bomb and left no doubt that if Iran accumulated a stockpile of 20% uranium sufficient for one nuclear bomb, Israel would act against the Iranian program. What few people remember is that the Iranians thereupon scrupulously ensured that their stockpile remained under the threshold needed for a bomb’s worth of material. It was almost certainly an instance of successful deterrence that deserves far greater study by US policymakers than it has received.

The risks associated with red lines, as with most deterrent threats, are well known. In the first instance, if crossed, they need to be enforced, requiring the United States to undertake difficult actions, often involving the use of force that no president is eager to commit to in advance. 

If not enforced, and exposed as nothing but an empty bluff, the impact on American credibility with adversaries far and wide could be damaging. 

For evidence, just see President Barack Obama’s red line regarding the Syrian regime’s use of chemical weapons in 2013. There’s also the dilemma that once a red line is communicated, it could be interpreted as giving an adversary licence to engage in all sorts of dangerous provocations just short of the threshold.

All these factors and others would need to be carefully assessed by the Biden Administration and weighed against the rising risk of Iran continuing on its present trajectory of pressing its program forward without any sense of outside constraints whatsoever – short of actually dashing to build a nuclear weapon.

Ideally, a red line strategy would be pursued with key allies in Europe and Israel. As JCPOA participants in good standing, the EU-3 wield the potentially powerful card of unilaterally invoking the deal’s snapback provisions, which would return the full weight of UN resolutions, sanctions, and diplomatic isolation crashing down on the Iranian regime’s head. 

With Europe’s bête noire, Donald Trump, now gone, and with a Biden team working in tandem with London, Paris, and Berlin to restore the JCPOA, the EU-3 might well be willing to finally unsheathe their snapback sword in the interest of a targeted red line strategy meant to deter the next major leaps forward in Iran’s nuclear advancement—whether that be accumulating a bomb’s worth of 20% uranium, moving to 60% enrichment, destroying critical information gathered through remote IAEA monitoring systems, or the industrial production of uranium metal. 

It’s certainly a conversation that the Administration should urgently be exploring with the EU-3, and would put some much-needed teeth behind an existing approach that is currently in danger of devolving into little more than endless hand-wringing over the danger of each new Iranian violation, pleading with the regime to return to JCPOA compliance, and offering a growing list of concessions and payoffs to entice Iran back.

Israel, of course, is the only other country along with the United States that can put forward a credible kinetic component, whether overt or covert, as part of a red line strategy. Indeed, in light of Israel’s stunning record of success in conducting direct action operations against Iran’s nuclear program, the Iranians may well take an Israeli red line more seriously than one coming from the United States alone. Far better, of course, if it were to come from both. The Biden Administration has convened a new strategic dialogue with Israel to try to develop a common approach, especially with respect to the Administration’s strategy on reviving the JCPOA. Those discussions have begun none too soon and the pros and cons of a possible red line strategy and how it could most effectively be implemented should be a central focus.

Biden and his advisors seem all in on an effort to get Iran back into compliance with the JCPOA. But as they work to do so, they readily acknowledge that, day by day, Iran’s nuclear advancements are becoming more and more dangerous. 

The Trump Administration, to its great discredit, never developed a serious answer to this growing threat when its plan A – forcing Iran to scale back its nuclear escalation through maximum economic pressure – failed to deliver. The question now is whether the Biden Administration can do better. 

Can it develop a diplomatic strategy for constraining Iran’s accelerating nuclear clock even as it seeks to revive negotiations – one that doesn’t just involve outright capitulation to Iran’s demands and the surrender of all US negotiating leverage and credibility? If the Administration is serious about the challenge, the issue of red lines should urgently rise to the top of its agenda.
