Negotiations between Iran and the United States over Tehran's rapidly advancing nuclear program will move Wednesday to what's known as the “expert level” — a sign analysts say shows that the talks are moving forward rapidly.

However, experts not involved in the talks who spoke with The Associated Press warn that this doesn't necessarily signal a deal is imminent. Instead, it means that the talks between Iranian Foreign Minister Abbas Araghchi and US Mideast envoy Steve Witkoff haven't broken down at what likely is the top-level trade — Tehran limiting its atomic program in exchange for the lifting of economic sanctions.

“Agreeing to technical talks suggests both sides are expressing pragmatic, realistic objectives for the negotiations and want to explore the details,” said Kelsey Davenport, the director for nonproliferation policy at the Arms Control Association who long has studied Iran's nuclear program.

“If Witkoff was making maximalist demands during his talks with Araghchi, such as dismantlement of the enrichment program, Iran would have no incentive to meet at the technical level.”

That technical level, however, remains filled with possible landmines. Just how much enrichment by Iran would be comfortable for the United States? What about Tehran's ballistic missile program, which US President Donald Trump first cited in pulling America unilaterally out of the accord in 2018? Which sanctions could be lifted and which would be remain in place on Tehran?

“The most important determinant of expert talks’ value lies in whether there is a political commitment to do something and experts just need to figure out what,” said Richard Nephew, an adjunct fellow at the Washington Institute for Near East Policy who worked on Iran sanctions while at the US State Department during negotiations over what became the 2015 nuclear deal.

“If the experts also have to discuss big concepts, without political agreement, it can just result in spun wheels.”

Experts and the 2015 nuclear deal

The 2015 nuclear deal saw senior experts involved in both sides of the deal. For the US under President Barack Obama, Energy Secretary Ernest Moniz reached an understanding working with Ali Akbar Salehi, then the leader of the Atomic Energy Organization of Iran. Both men's technical background proved key to nailing down the specifics of the deal.

Under the 2015 agreement, Iran agreed to enrich uranium only to 3.67% purity and keep a stockpile of only 300 kilograms (661 pounds). Today, Iran enriches some uranium up to 60% purity — a short, technical step away from weapons-grade levels of 90%. The last report by the International Atomic Energy Agency put Iran's overall uranium stockpile in February at 8,294.4 kilograms (18,286 pounds).

The deal also limited the types of centrifuges Iran could spin, further slowing Tehran's ability to rush for a bomb, if it chose to do so. It also set out the provisions of how and when sanctions would be lifted, as well as time limits for the accord itself.

Reaching limits, relief and timelines require the knowledge of experts, analysts say.

“A nonproliferation agreement is meaningless if it cannot be effectively implemented and verified,” Davenport said. “The United States needs a strong technical team to negotiate the detailed restrictions and intrusive monitoring that will be necessary to ensure any move by Iran toward nuclear weapons is quickly detected and there is sufficient time to respond.”

It remains unclear who the two sides will be sending for those negotiations.

Hiccups already heard in these negotiations

Both the Americans and the Iranians have been tightlipped over exactly what's been discussed so far, though both sides have expressed optimism about the pace. However, there has been one noticeable dispute stemming from comments Witkoff made in a television interview, suggesting Tehran could be able to enrich up to 3.67% purity. However, analysts noted that was the level set by the 2015 deal under Obama.

Witkoff hours later issued a statement suggesting that comparison struck a nerve: “A deal with Iran will only be completed if it is a Trump deal.”

“Iran must stop and eliminate its nuclear enrichment and weaponization program,” Witkoff added.

Araghchi responded by warning that Iran must be able to enrich.

"The core issue of enrichment itself is not negotiable,” he said.

Despite that, experts who spoke to the AP said they remained positive about the talks' trajectory so far.

“Although still early stages, I’m encouraged so far,” said Alan Eyre, a former US diplomat once involved in past nuclear negotiations with Tehran. “The pace of negotiations — to include starting expert level meetings this Wednesday — is good.”

He added that so far, there didn't appear to be any “mutually exclusive red lines” for the talks as well — signaling there likely wasn't immediately any roadblocks to reaching a deal.

Nephew similarly described reaching the expert level as a “positive sign.” However, he cautioned that the hard work potentially was just beginning for the negotiations.

“They imply the need to get into real details, to discuss concepts that senior (officials) might not understand and to answer questions. I also think too much can be read into them starting,” Nephew said. “Expert talks can sometimes be a fudge for seniors to avoid working on tough issues — ‘let’s have experts discuss it while we move on to other things’ — or to sidestep big political decisions."

Corey Hinderstein, the vice president for studies at the Carnegie Endowment for International Peace and a former US government nuclear expert, described herself as feeling “cautious optimism” over the expert talks beginning.

“Heads of delegation are responsible for setting strategic goals and defining success,” she said. “But if there is a deal to be made, the technical experts are the ones who will get it done.”



Will Israel’s Interceptors Outlast Iran’s Missiles?

Will Israel’s Interceptors Outlast Iran’s Missiles?

Israel has a world-leading missile interception system but its bank of interceptors is finite. Now, as the war drags on, Israel is firing interceptors faster than it can produce them.

On Thursday, The New York Times reporters spoke to current and former Israeli officials about the strengths and weaknesses of Israeli air defense.

Aside from a potentially game-changing US intervention that shapes the fate of Iran’s nuclear program, two factors will help decide the length of the Israel-Iran war: Israel’s reserve of missile interceptors and Iran’s stock of long-range missiles.

Since Iran started retaliating against Israel’s fire last week, Israel’s world-leading air defense system has intercepted most incoming Iranian ballistic missiles, giving the Israeli Air Force more time to strike Iran without incurring major losses at home.

But now, as the war drags on, Israel is firing interceptors faster than it can produce them. That has raised questions within the Israeli security establishment about whether the country will run low on air defense missiles before Iran uses up its ballistic arsenal, according to eight current and former officials.

Already, Israel’s military has had to conserve its use of interceptors and is giving greater priority to the defense of densely populated areas and strategic infrastructure, according to the officials. Most spoke on the condition of anonymity to speak more freely.

Interceptors are “not grains of rice,” said Brig. Gen. Ran Kochav, who commanded Israel’s air defense system until 2021 and still serves in the military reserve. “The number is finite.”

“If a missile is supposed to hit refineries in Haifa, it’s clear that it’s more important to intercept that missile than one that will hit the Negev desert,” General Kochav said.

Conserving Israel’s interceptors is “a challenge,” he added. “We can make it, but it’s a challenge.”

Asked for comment on the limits of its interceptor arsenal, the Israeli military said in a brief statement that it “is prepared and ready to handle any scenario and is operating defensively and offensively to remove threats to Israeli civilians.”

No Israeli official would divulge the number of interceptors left at Israel’s disposal; the revelation of such a closely guarded secret could give Iran a military advantage.

The answer will affect Israel’s ability to sustain a long-term, attritional war. The nature of the war will partly be decided by whether Trump decides to join Israel in attacking Iran’s nuclear enrichment site at Fordo, in northern Iran, or whether Iran decides to give up its enrichment program to prevent such an intervention.

But the war’s endgame will also be shaped by how long both sides can sustain the damage to their economies, as well as the damage to national morale caused by a growing civilian death toll.

Israel relies on at least seven kinds of air defense. Most of them involve automated systems that use radar to detect incoming missiles and then provide officers with suggestions of how to intercept them.

Military officials have seconds to react to some short-range fire, but minutes to judge the response to long-range attacks. At times, the automated systems do not offer recommendations, leaving officers to make decisions on their own, General Kochav said.

The Arrow system intercepts long-range missiles at higher altitudes; the David’s Sling system intercepts them at lower altitudes; while the Iron Dome takes out shorter-range rockets, usually fired from Gaza, or the fragments of missiles already intercepted by other defense systems.

The United States has supplied at least two more defense systems, some of them fired from ships in the Mediterranean, and Israel is also trying out a new and relatively untested laser beam. Finally, fighter jets are deployed to shoot down slow-moving drones.

Some Israelis feel it is time to wrap up the war before Israel’s defenses are tested too severely.

At least 24 civilians have been killed by Iran’s strikes, and more than 800 have been injured. Some key infrastructure, including oil refineries in northern Israel, has been hit, along with civilian homes. A hospital in southern Israel was struck on Thursday morning.

Already high by Israeli standards, the death toll could rise sharply if the Israeli military is forced to limit its general use of interceptors in order to guarantee the long-term protection of a few strategic sites like the Dimona nuclear reactor in southern Israel or the military headquarters in Tel Aviv.

“Now that Israel has succeeded in striking most of its nuclear targets in Iran, Israel has a window of two or three days to declare the victory and end the war,” said Zohar Palti, a former senior officer in the Mossad, Israel’s spy agency.

“When planning how to defend Israel in future wars, no one envisaged a scenario in which we would be fighting on so many fronts and defending against so many rounds of ballistic missiles,” said Palti, who was for years involved in Israel’s defensive planning.

Others are confident that Israel will be able to solve the problem by destroying most of Iran’s missile launchers, preventing the Iranian military from using the stocks that it still has.

Iran has both fixed and mobile launchers, scattered across its territory, according to two Israeli officials. Some of its missiles are stored underground, where they are harder to destroy, while others are in aboveground caches, the officials said.

The Israeli military says it has destroyed more than a third of the launchers. Officials and experts say that has already limited the number of missiles that Iran can fire in a single attack.

US officials said Israel’s strikes against the launchers have decimated Iran’s ability to fire its missiles and hurt its ability to create large-scale barrages.

“The real issue is the number of launchers, more than the number of missiles,” said Asaf Cohen, a former Israeli commander who led the Iran department in Israel’s military intelligence directorate.

“The more of them that are hit, the harder it will be for them to launch barrages,” Cohen added. “If they realize they have a problem with launch capacity, they’ll shift to harassment: one or two missiles every so often, aimed at two different areas simultaneously.”
