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.”

Israeli Attack Exposed Iran's Military 'Vulnerability', Say Analysts

Israel's strikes on archfoe on Iran Friday exposed severe weaknesses for Tehran that have hampered its ability to respond militarily, analysts said.

Israel said it hit 100 targets including Iranian nuclear and military sites in the attacks, killing senior figures, among them the armed forces' chief and top nuclear scientists.

Supreme leader Ali Khamenei warned Israel it faces a "bitter and painful" fate over the attacks, but analysts say the country's options are limited.

"This is an intelligence defeat of existential proportions for Iran," said Ali Fathollah-Nejad, director of the Berlin-based Center for Middle East and Global Order (CMEG) think tank.

"It exposes the vital vulnerability of the regime's military and security apparatus and its key infrastructures, including nuclear, as well as its top political and military leadership," he told AFP.

"All this is meant, inter alia, to cripple Tehran's command and counter-strike capacities."

The United States and other Western countries, along with Israel, accuse Iran of seeking a nuclear weapon.

Tehran denies that, but has gradually broken away from its commitments under the 2015 nuclear deal it struck with world powers, after the United States pulled out of it.

The landmark accord provided Iran sanctions relief in exchange for curbs on its atomic program, but it fell apart after President Donald Trump halted US participation in 2018, during his first term.

Western nations in recent days accused Tehran of deliberately escalating its nuclear program, despite several rounds of US-Iran talks for a new accord.

Iran's Atomic Energy Organization said Thursday it would "significantly" increase production of enriched uranium, after the UN's nuclear watchdog found Tehran in breach of its obligations.

Israel has previously carried out attacks in Iran, including against military targets in October last year.

But Friday's attacks were unprecedented.

"The Israel campaign is sweeping in scope and sophistication," said Ali Vaez, of the International Crisis Group.

"We may still only be in the early stages of a prolonged operation that continues to expand, disrupting Iran's ability to either formulate or execute a response."

Israeli Prime Minister Benjamin Netanyahu warned his country's military operation would "continue for as many days as it takes to remove this threat".

Friday's strikes killed Iran's highest-ranking military officer, armed forces chief of staff Mohammad Bagheri, and the head of the powerful Iranian Revolutionary Guard Corps, Hossein Salami, Iranian media reported.

A senior advisor to Khamenei was also wounded, state television said.

Clement Therme, of the Sorbonne University, said that "to retaliate, the regime seems to be in a bind".

"Either it targets US bases in the region and jeopardizes its future, or it targets Israel, but we see that its military capabilities are limited," he said.

The Israeli military said Iran launched around 100 drones against it, but its air defenses intercepted "most" of them outside Israeli territory.

Israel, which relies on US diplomatic and military support, carried out the attack despite Trump's public urging for it to give time for diplomacy.

Trump's Middle East pointman Steve Witkoff had been set to hold a sixth round of talks with Iran on Sunday in Oman.

A Western diplomat earlier this year described Iran's economy as "cataclysmic", saying the country had "a gigantic need for the lifting of sanctions, reforms, a cleanup of the banking system, foreign investments".

Ellie Geranmayeh, an Iran expert at the European Council on Foreign Relations, said the strikes were "designed to kill President Trump's chances of striking a deal to contain the Iranian nuclear program".

"It is highly unlikely that in these conditions, Iran will proceed with the Omani-mediated talks scheduled for Sunday," she added.

But, after the strikes, a US official said Washington still hoped the Sunday talks would go ahead.

Trump urged Iran to "make a deal, before there is nothing left", warning that otherwise there will be more "death and destruction".

Vaez warned the strategy may not work.

"Rather than prompt Iranian concessions it could also lead to a doubling down by Tehran," he said.

"Setbacks could lead Iran to reconstitute their operations with a more determined effort to obtain a nuclear deterrent."
