# Growing Fears of Massive Strikes On Iran As Nuclear Negotiations Sputter

U.S. President Donald Trump has been presented with a broad array of [potential military options against Iran](<https://www.twz.com/air/is-the-u-s-about-to-go-to-war-with-iran.md>) should ongoing nuclear negotiations with that country fail. Israel is already reportedly moving ever closer to at least being in a position to launch its own strikes on [Iranian nuclear sites](<https://www.twz.com/iranian-underground-nuclear-facility-may-be-a-hard-target-for-americas-biggest-bunker-busters.md>). The direct and indirect blowback from any such operations against Iran could be immense.

Fears that U.S.-Iranian nuclear talks are on the verge of collapse have been steadily growing in the past week or so amid statements from both sides outlining potentially intractable positions. Iran's ability to continue domestic enrichment of nuclear material that could be used to produce nuclear weapons has emerged as a key stumbling block to reaching a deal.

"If the President directed \[it\], is CENTCOM \[U.S. Central Command\] prepared to respond with overwhelming force to prevent a nuclear-armed Iran?" Congressman Mike Rogers, an Alabama Republican, asked U.S. Army Gen. Michael "Erik" Kurilla at a hearing of the House Armed Services Committee today. Kurilla is currently head of CENTCOM, making him the top officer overseeing operations across the Middle East.

"I have provided the Secretary of Defense \[Pete Hegseth\] and the President \[Trump\] a wide range of options," Kurilla said in response.

"I take that as a yes?" Rogers, the present chairman of the House Armed Services Committee, asked in return, appearing to refer to the specific wording of his question, to include the possible use of "overwhelming force."

"Yes," Kurrila said.

It is important to note here that U.S. presidents and defense secretaries regularly ask to be briefed on potential military options in light of crises or heightened risks of one erupting. Being presented with a full range of operational possibilities, including large-scale strikes or other significant direct action, does not mean the United States is automatically committed to pursuing any specific course of action, something we will come back to later on.

Publicly, Trump has [consistently advocated for reaching a deal](<https://www.timesofisrael.com/trump-speaks-with-netanyahu-stresses-us-wants-iran-deal-so-theres-no-destruction-and-death/>) with Iran to avoid any need to take military action, though he has also raised the possibility of military action in the event talks reach a dead end. He has separately said that he has pressed his Israeli counterpart, Prime Minister Benjamin Netanyahu, [to hold off on striking Iranian targets](<https://apnews.com/article/iran-us-nuclear-talks-0613bd70b6a47ed2f583177e54473a21>) while negotiations are ongoing. There have [been reports of significant friction](<https://www.timesofisrael.com/report-netanyahu-trump-phone-call-on-iran-was-marked-by-heated-disagreements/>) between [the two world leaders](<https://www.washingtonpost.com/world/2025/05/12/trump-netanyahu-middle-east-trip/>), as well. Amid all this, the U.S. president is said to be facing increasingly intense pressure from a faction of domestic political allies to acquiesce to and/or join in on Israeli attacks on Iran, according to a [new report just today from *Politico*](<https://www.politico.com/news/2025/06/10/iran-trump-maga-hawks-00394820>).

There have been reports for weeks already that the Israel Defense Forces (IDF) have been actively planning and otherwise preparing to launch strikes on Iran, and the country's nuclear sites in particular. Israel's *Haaretz* newspaper [reported yesterday](<https://www.haaretz.com/israel-news/2025-06-09/ty-article/.premium/israel-advancing-preparations-for-iran-strike-amid-obstacles-in-u-s-tehran-talks/00000197-561f-deed-a9bf-5f7fcd5c0000>) that those plans continue to advance, while the country's Channel 12 television station had said that more active preparations, including the prepositioning of munitions, may now be underway. It is also worth noting that there have been persistent reports about possible Israeli strikes on Iran for some time, but that this actually [came to pass on a more limited level](<https://www.twz.com/news-features/israels-reprisal-strike-carefully-calculated-unclear-if-jets-ever-flew-over-iran.md>) last year. Authorities in Israel have also [demonstrated a new willingness](<https://www.twz.com/news-features/details-of-israels-long-range-strike-that-decimated-yemeni-port-emerge.md>) to [launch overt attacks](<https://www.twz.com/news-features/israel-executes-massive-bunker-buster-strike-on-hezbollah-command-headquarters-in-beirut.md>) beyond the country's borders, in general.

"Iran is acting much differently in negotiations than it did just days ago," Trump [said in an interview today](<https://www.foxnews.com/politics/iran-becoming-much-more-aggressive-nuclear-talks-trump-tells-fox-news>) with *Fox News*' Bret Baier. "Much more aggressive. It’s surprising to me. It’s disappointing, but we are set to meet again tomorrow – we’ll see."

Trump had told reporters that the next round of U.S.-Iranian nuclear talks was scheduled for Thursday during a question-and-answer session around an Invest America roundtable with multiple corporate CEOs at the White House yesterday. It is unclear whether or not this plan has changed.

"We have a meeting with Iran on Thursday. So we're going to wait till Thursday," Trump had said. "They're just asking for things that you can't do. They don't want to give up what they have to give up. You know what that is. They seek enrichment. We can't have enrichment. We want just the opposite."

https://twitter.com/RudawEnglish/status/1932164921736990724

"And so far, they're not there. I hate to say that, because the alternative is a very, very dire one, but they're not there," the U.S. president continued. "They have given us their thoughts on the deal. I said, you know, it's just not acceptable."

"We discussed a lot of things, and it went very well, very smooth. We'll see what happens. You know, we're trying to do something with a country we just spoke about, Iran," Trump said at the same White House event yesterday in response to questions about a telephone conversation earlier in the day with Netanyahu. "They \[the Iranians\] are good negotiators, but they're tough. Sometimes they can be too tough. That's the problem, we're trying to make a deal so that there's no destruction and death. And we've told them that, and I've told them that. I hope that's the way it works out, but it might not work out that way. We'll soon find out."

Iran “won’t be enriching,” Trump had already told reporters this past weekend. "If they enrich, then we’re going to have to do it the other way."

Domestic Iranian capacity to enrich Uranium to a level of purity required to make effective nuclear weapons [has long been a sticking point](<https://www.bbc.com/news/articles/c1mg7kx2d45o>) between Tehran and much of the international community. The U.S. Intelligence Community, among others, continues to assess that Iran does not have an active nuclear weapons program, but that the country has put itself in a position where it could build one within as little as a week if it chose to do so. The United States, Israel, and others, including the International Atomic Energy Agency (IAEA), [have also accused Iran of lying](<https://www.twz.com/20531/new-syria-strikes-cause-earthquake-as-israel-drops-intelligence-bombshell-about-iran.md>), or [at least being far less than forthcoming](<https://isis-online.org/isis-reports/mobile/the-iaeas-iran-npt-safeguards-report-may-2022>), about the full extent of its nuclear efforts to date.

Signals from the Trump administration on the enrichment issue specifically have been mixed in recent weeks. [*Axios* reported just last week](<https://www.axios.com/2025/06/02/iran-nuclear-deal-proposal-enrich-uranium>) that a proposed U.S. deal might allow Iran to continue enriching uranium to lower purity levels associated with civilian nuclear generation. A previous multi-national deal with Iran that the United States was party to, called the Joint Comprehensive Plan of Action (JCPOA), had also put limits on Iranian enrichment, but did not require it to be stopped outright. Trump [withdrew the United States from the JCPOA](<https://www.twz.com/20717/heres-what-you-need-to-know-about-what-trump-just-did-to-the-iran-nuclear-deal.md>) in 2018 during his first term in office. Iran announced in 2020 that it was no longer abiding by any of the agreement's stipulations.

For its part, Iran has stressed repeatedly that it is not willing to completely abandon its domestic enrichment efforts. Iranian authorities have also said they want a clear, formalized plan for relief from U.S. sanctions as part of any new nuclear agreement.

"The U.S. proposal is not acceptable to us. It was not the result of previous rounds of negotiations. We will present our own proposal to the other side via Oman after it is finalized. This proposal is reasonable, logical, and balanced," Iranian foreign ministry spokesperson Esmaeil Baghaei said early today, [according to *Reuters*](<https://www.reuters.com/world/middle-east/iran-present-counter-proposal-us-nuclear-talks-foreign-ministry-says-2025-06-09/>). "We must ensure before the lifting of sanctions that Iran will effectively benefit economically and that its banking and trade relations with other countries will return to normal."

"Uranium enrichment is the key to our nuclear program and the enemies have focused on the enrichment," Iranian Supreme Leader Ayatollah Ali Khamenei also said last week during a televised address, [again per *Reuters*](<https://www.reuters.com/world/middle-east/irans-supreme-leader-says-us-nuclear-proposal-undermines-its-national-power-2025-06-04/>). "The proposal that the Americans have presented is 100% against our interests ... The rude and arrogant leaders of America repeatedly demand that we should not have a nuclear programme. Who are you to decide whether Iran should have enrichment?"

Majid Takht-e-Ravanchi, Iran's Deputy Foreign Minister for Political Affairs, also indicated yesterday that Iran could be looking to extend negotiations without necessarily outright rejecting a particular proposal.

“Our proposal is certainly not a one-sentence or one-paragraph text that can be easily dismissed," Takht-e-Ravanchi [explained in an interview](<https://en.irna.ir/news/85856828/Exclusive-I-Iran-s-response-to-U-S-proposal-will-be-logical>) with state-run *IRNA*. "It contains elements that demonstrate our seriousness, show that our position has a defined framework, and indicate that we intend to work based on established principles. Our approach is logical.”

“The reality is that we are not discussing an excessively lengthy text at this stage because we do not intend to present a comprehensive, time-consuming agreement or understanding. The proposal we have submitted serves as a framework for an agreement. If there is mutual understanding regarding this framework, we can then begin more detailed negotiations on specific issues.”

If U.S. negotiations with Iran do collapse, and American and/or Israeli attacks on nuclear facilities or other targets follow, it is unclear what the scale and scope of that operation might be, as already noted.

The IDF has already demonstrated an ability to launch precision [standoff strikes on Iran with virtual impunity](<https://www.twz.com/news-features/israels-reprisal-strike-carefully-calculated-unclear-if-jets-ever-flew-over-iran.md>) in the past year, but only against targets on the surface. Israeli forces would face significantly greater challenges in neutralizing deeply [buried sites tied to Iran's nuclear program](<https://www.twz.com/iranian-underground-nuclear-facility-may-be-a-hard-target-for-americas-biggest-bunker-busters.md>). *TWZ* [highlighted this reality](<https://www.twz.com/news-features/israeli-commando-raid-in-syria-sends-a-message-to-iran-that-its-on-underground-bases-are-not-untouchable.md>) after Israel announced its special operations forces had conducted [a dramatic ground raid](<https://www.twz.com/air/inside-israels-commando-raid-on-irans-underground-missile-factory-in-syria.md>) on an underground missile production facility in Syria last year.

“What member states decide to do is their prerogative," IAEA Director-General Rafael Grossi [told *The Jerusalem Post* yesterday](<https://www.jpost.com/middle-east/iran-news/article-857108>). "I don’t advise the Israeli government. They will decide what’s best."

“But one thing is certain,” he added, “The \[Iranian nuclear\] program runs wide and deep. And when I say ‘deep,’ I mean it. Many of these facilities are extremely well-protected. Disrupting them would require overwhelming and devastating force.”

This is where questions about U.S. participation typically come into the picture. America's armed forces have a unique conventional deep-penetrating strike capability in the form of [B-2 Spirit stealth bombers](<https://www.twz.com/28076/new-video-of-b-2-bomber-dropping-mother-of-all-bunker-busters-sends-ominous-message.md>) armed with [GBU-57/B Massive Ordnance Penetrator](<https://www.twz.com/air/massive-ordnance-penetrator-bunker-buster-grows-more-potent-thanks-to-new-tests.md>) (MOP) bunker buster bombs. *TWZ* highlighted the significance of this combination in reporting around the unusually large deployment of six [B-2s to the Indian Ocean island of Diego Garcia](<https://www.twz.com/air/signs-u-s-massing-b-2-spirit-bombers-in-diego-garcia.md>) between March and May of this year, as well as the use of those bombers [in strikes on Yemen last October](<https://www.twz.com/air/b-2-spirits-just-sent-a-very-ominous-message-to-iran-that-only-they-can.md>). In both cases, we also pointed out the clear strategic signalling aimed at Iran.

*USAF*

The B-2 bombers on Diego Garcia represented just a portion of the additional U.S. forces and materiel that flowed into the Middle East since the beginning of the year. In addition, last week, [reports began to emerge](<https://www.wsj.com/politics/national-security/us-halts-ukraine-anti-drone-russia-ce0b5b75?gaa_at=eafs&gaa_n=ASWzDAjCpndFW5PjCCCjHu6arrBCmvCQpjhGLbkNLTIypp8ch7_OkPkviWW8&gaa_ts=68489687&gaa_sig=8CA3TJIgDsW5loeSD1fta-TfEKAD343zzzcTO90w_ftXR5DBMCUzNuwYCMPz5kBKrgWyzUTDr1uvoGWDd1ZDxQ%3D%3D>) that the U.S. military had diverted counter-drone capabilities [originally intended to be delivered to Ukraine](<https://kyivindependent.com/trump-redirects-20-000-anti-drone-missiles-meant-for-ukraine-zelensky-confirms/>) to American forces in the Middle East.

Like Israel, the U.S. military could also launch its own standoff strikes on Iran via other aircraft, as well as ships and submarines, but would face similar limitations in the kinds of targets it might be able to prosecute. Questions have even been raised in the past about whether some of Iran's underground nuclear facilities [might be beyond the reach](<https://www.twz.com/iranian-underground-nuclear-facility-may-be-a-hard-target-for-americas-biggest-bunker-busters.md>) even of the MOP. Strikes that do not fully destroy facilities could still put them out of commission for at least a limited time. Ground raids could also be launched as part of what might be a protracted campaign.

Any such operation would require a much larger force package beyond just the assets tasked with carrying out the strikes, including to suppress and destroy hostile air defenses, and would present additional risks as a result. U.S. operations targeting Iranian-backed Houthi militants in Yemen in the past year or so have highlighted how even more rudimentary air defenses can still present real threats to even advanced American aircraft, as you can read more about [here](<https://www.twz.com/air/how-the-houthis-rickety-air-defenses-can-threaten-the-stealthy-f-35.md>). All of this would be further magnified by any need to mount a combat search and rescue effort to recover American personnel should their aircraft be downed inside Iran.

The Houthis' [arsenal of ballistic and cruise missiles](<https://www.twz.com/the-anti-ship-missile-arsenal-houthis-are-firing-into-the-red-sea.md>), as well as kamikaze drones, which the group has amassed with immense help from Iran, also underscores the dangers U.S. warships could face from Iranian retaliation.

*TWZ* [already explored the potential broader ramifications](<https://www.twz.com/air/is-the-u-s-about-to-go-to-war-with-iran.md>) of a major conflict between the United States and Iran in detail earlier this year amid another spike in tensions between the two countries. Iran has long vowed to carry out a broad retaliatory response if its nuclear facilities are targeted. This could include missile and drone attacks on Israeli and U.S. interests across the Middle East on a scale and scope not seen ever before, as well as similar actions by proxy forces like the Houthis, along with terrorist attacks globally.

“We have a rule in CENTCOM: you improve your foxhole every single day," Kurrila also said at today's hearing.

Just this week, Iranian authorities explicitly [threatened to strike Israeli nuclear sites](<https://www.tasnimnews.com/en/news/2025/06/10/3331696/iran-warns-of-retaliatory-strike-on-israel-s-clandestine-nuclear-facilities>) if their own are targeted. This followed claims from Iran’s intelligence minister, Esmail Khatib, that his country is in possession of a trove of secrets about [Israel's unacknowledged nuclear arsenal](<https://www.armscontrol.org/factsheets/nuclear-weapons-who-has-what-glance>), which he has also threatened to publicly release. This remains largely unconfirmed, but [IAEA's Grossi has indicated](<https://www.timesofisrael.com/iaea-chief-says-information-stolen-by-iran-refers-to-israeli-nuclear-research-site/>) that the information Iran has relates primarily to Israel's publicly acknowledged Soreq nuclear research facility.

It's also worth noting that Iran's general ability to threaten missile and drone attacks on targets further away from its shores has steadily grown in recent years. The U.S. Air Force's deployment in May of a contingent of F-15E Strike Eagle combat jets to provide force protection on Diego Garcia, which [*TWZ* was first to report](<https://www.twz.com/air/f-15-eagles-deploy-to-diego-garcia-to-protect-the-indian-ocean-outpost.md>), highlights this fact. The island, where a force of a B-52 bombers also remains forward-deployed, has historically been seen as being less vulnerable, especially to smaller potential adversaries like Iran, simply due to its remoteness.

Grossi, among others, [has also warned](<https://www.aljazeera.com/news/2025/6/9/israeli-attack-could-drive-iran-to-seek-nuclear-weapons-warns-iaea-chief>) that attacks on Iran's nuclear facilities could prompt the country to start an active nuclear weapons program. The U.S. Intelligence Community [has publicly assessed](<https://www.dni.gov/files/ODNI/documents/assessments/ATA-2025-Unclassified-Report.pdf>) that Iranian Supreme Leader Khamenei is already under increasing pressure from domestic hardliners to do so.

There is clear potential for other second-order impacts, as well. Iranian authorities have threatened the [possibility of blockading the Strait of Hormuz](<https://www.twz.com/22577/iran-to-practice-blockading-strait-of-hormuz-as-saudis-say-mandeb-strait-is-no-longer-safe.md>), which links the Persian Gulf to the Gulf of Oman, in times of heightened tensions in the past. Doing so would have major impacts on global oil and natural gas supplies. Yemen's Houthis [have already massively disrupted international shipping](<https://www.bloomberg.com/news/articles/2025-05-01/how-houthi-red-sea-ship-attacks-upended-global-trade>) with attacks on commercial vessels in and around the Red Sea in the past year or so. Regional and global impacts could draw in other countries and create additional complexities. [Russia](<https://www.reuters.com/world/iran-send-russia-launchers-short-range-missiles-sources-say-2025-05-09/>) and [China](<https://www.newsweek.com/iran-china-missile-fuel-import-us-tensions-2081804>), for instance, have deep ties to Iran and interests in keeping the current regime in Tehran in place.

All told, it remains to be seen whether the United States and/or Israel will launch attacks on Iran, including its nuclear sites. At the same time, that decision looks to heavily hinge on the increasingly uncertain future of ongoing U.S.-Iranian negotiations.
