مصاحبه با رادیو ملی آمریکا:حمله آمریکا و اسرائیل به ایران، دو دینامیک قدرتمندمردم ایران را شعله ور کرده است:ملی‌گرایی و ایدئولوژی شیعه

سید حسین موسویان- بیست و سوم مارس 2026

مجری: جمعه شب، رئیس‌جمهور ترامپ اعلام کرد که در حال بررسی کاهش تلاش‌های نظامی در منطقه است. واکنش شما به این خبر چه بود؟

موسویان: در واقع، رئیس‌جمهور پرزیدنت ترامپ گفت که می‌خواهد جنگ را کاهش دهد. در مصاحبه دیگری گفت که جنگ خیلی زود به پایان می‌رسد. با این حال، در مصاحبه دیگری هم گفت چرا باید آتش‌بس برقرار کنیم وقتی ایران را در حال شکست دادن هستیم؟ واقعاً نمی‌دانم کدام یک از این اظهارات بازتاب‌دهنده نیت واقعی رئیس‌جمهور است. با این وجود، امیدوارم تصمیمی برای پایان دادن به این جنگ اتخاذ شود، زیرا تا کنون ایران، اسرائیل و آمریکا همگی متحمل خسارات بی‌سابقه‌ای شده‌اند

مجری: طی سه هفته گذشته برخی مقامات ارشد ایران کشته شده‌اند ازجمله علی لاریجانی.. از دیدگاه کلان، فکر می‌کنید تأثیر پایدار این ترورها چه خواهد بود؟

موسویان: حمله آمریکا و اسرائیل به ایران، به ویژه ترور مقامات ارشد، دو دینامیک قدرتمند در داخل کشور را شعله ور کرده است – “ملی‌گرایی و ایدئولوژی شیعه”. مردم ایران عملاً  شاهد بوده‌اند که طی سه هفته جنگ آمریکا و اسرائیل بیش از ۱۰ هزار غیرنظامی کشته یا زخمی شده‌اند. و تقریباً ۲۰۰ مقام ایرانی از سال ۲۰۲۵ توسط جنگ‌های آمریکا و اسرائیل ترور شده‌اند. با این حال، حتی تحت بمباران، ده‌ها هزار نفر در مراسم خاک‌سپاری آن‌ها شرکت کرده‌اند. در سنت شیعه، کسانی که در راه اسلام یا وطن کشته می‌شوند شهید یا قهرمان تلقی می‌شوند. این پدیده اکنون در مورد ترور مقامات ایرانی رخ داده است

مجری: در این شرایط، به نظر می‌رسد قدرت بیشتری به سپاه پاسداران منتقل می‌شود. در این زمینه چه باید فهمید؟

موسویان: در ۱۵ سال گذشته، با تجربه ۴۰ ساله‌ام در روابط ایران و آمریکا و فعالیت دانشگاهی در پرینستون، بارها توضیح داده‌ام که تحریم‌ها و فشارهای بیشتر، سیاستهای ایران را بیش از پیش رادیکال می‌کند. همین اتفاق هنگام خروج آمریکا از برجام افتاد. آمریکا از برجام خارج شد و تحریمها را اعاده کرد و ایران سطح و ظرفیت غنی‌سازی خود را افزایش داد. حالا که آمریکا به ایران حمله کرده است، طبیعی است که نیروهای نظامی کشور عملاً کنترل بیشتری پیدا کنند

مجری: ایران حدود ۴۰۰ کیلوگرم اورانیوم غنی‌شده دارد. فکر می‌کنید چه اتفاقی برای این ذخایر خواهد افتاد؟

موسویان: واقعیت این است که در مذاکرات بین نمایندگان آمریکا – ویتکاف، کوشنر – و نمایندگان ایران در فوریه ۲۰۲۶، آقای عراقچی مذاکره‌کننده ایرانی به صراحت به طرف آمریکایی گفت که اگر توافقی حاصل شود، ایران آماده است کل اورانیوم غنی‌شده ۶۰٪ را رقیق کند و آن را کنار بگذارد. این موضوع رسماً توسط وزیر امور خارجه عمان اعلام شد. حتی اخیراً – نمی‌دانم مقاله گاردین را خوانده‌اید یا نه – مشاور امنیت ملی بریتانیا در جلسه فوریه ۲۰۲۶ شرکت کرد و تأیید کرد که ایران آماده است کل ذخایر اورانیوم ۶۰٪ را کنار بگذارد. بنابراین، اگر توافقی وجود داشته باشد، ایران مشکلی ندارد و قصد نگه‌داشتن آن را ندارد

مجری: فکر میکنید آیا هنوز جای دیپلماسی باقی مانده است، با توجه به اینکه آمریکا این جنگ را در میانه مذاکرات سازنده آغاز کرده است؟

موسویان: صادقانه بگویم، این بسیار دشوار و پیچیده است، زیرا آمریکا به ایران حمله کرده است. همان‌طور که وزیر امور خارجه عمان گفت، دو بار مذاکره انجام شد و پیشرفت قابل توجهی حاصل شده بود، آن‌ها بسیار به توافق نزدیک بودند، اما آمریکا تصمیم گرفت حمله کند. بنابراین اعتماد بیش از پیش از بین رفته است. با این حال، من معتقد نیستم که در را برای دیپلماسی کاملاً بسته باشد. واقعاً نمی‌دانم آمریکا دنبال چه نوع توافقی با ایران است. شما شنیدید که نخست‌وزیر نتانیاهو گفت استراتژی اسرائیل خاورمیانه بزرگ است. شنیدید که سفیر آمریکا در اسرائیل گفت اسرائیل حق دارد کشورهای خاورمیانه را تحت کنترل بگیرد. مدیر انرژی کاخ سفید گفت هدف کنترل نفت ایران است.واقعاً نمی‌دانم. اگرهدف واقعی آمریکا سقوط حکومت و تصاحب نفت و ثروت ایران باشد، در این صورت هرگز توافقی رخ نخواهد داد

Interview with NPR: As the war in Iran expands, can diplomacy help end it?

By Seyed Hossein Mousavian, March 21, 2026

ADRIAN MA, HOST:

As the war with Iran enters its fourth week, President Trump said on Friday, he’s considering, quote, “winding down” military efforts in the region. But ending the conflict may not be that easy. Iran has continued its retaliatory attacks, including an unsuccessful attempt to bomb the Diego Garcia air base, which is managed by U.S. and U.K. militaries.

And that came after a week of bombings in Iran targeting strategic sites and killing some of the country’s top leaders. One of them was Ali Larijani, the country’s top civilian leader. Before he was killed, Larijani was seen as someone who might be willing to negotiate with the West, and all of this leaves the path to a negotiated peace murky.

Hossein Mousavian is a former Iranian nuclear negotiator. He’s also a former policy advisor to Ali Larijani. He’s currently a research collaborator at Princeton University’s program on science and global security, and he joins us now. Thanks for being here.

HOSSEIN MOUSAVIAN: Thank you.

MA: So, on Friday night, President Trump announced on social media that he’s considering winding down military efforts in the region. What was your reaction to that?

MOUSAVIAN: Actually, the president said he wants to wind it down in another interview. Also he said the same – he said, the war will end very soon. However, in another interview, he asked, why should we have a ceasefire when we are defeating Iran? I really don’t know which statement reflects the president’s real intention. Nevertheless, I hope a decision is made to bring this war to an end because so far, Iran, Israel and the U.S. have all suffered unprecedented losses.

MA: So, it’s sending mixed messages there. And this follows, as we said, killings over the last three weeks of some top-level officials in Iran – Ali Larijani, the head of Iran’s Supreme National Security Council and a public policy advisor to Iran’s supreme leader, was killed. And from a high level, what do you think will be the lasting impact of these assassinations?

MOUSAVIAN: The U.S.-Israeli attack on Iran, specifically assassinating the top levels, has ignited two powerful dynamics within the country – nationalism and Shiite ideology. People inside Iran have witnessed practically – I mean, daily, they have witnessed that over the past three weeks of the U.S-Israeli war, more than 10,000 civilians have been killed or injured. And approximately, I would say, 200 Iranian officials have been assassinated by the U.S.-Israeli wars since 2025. Yet you see or you have seen, even under bombardments, tens of thousands of people have participated in their funeral ceremonies. In Shia tradition, there is a concept whereby those who are killed in the path of Islam or their homeland are regarded as martyrs or are viewed as heroes. This phenomenon now is unfolding in the case of assassination of Iranian officials.

MA: So, in this current climate, it seems that more power is shifting to the Revolutionary Guard. What should we understand about that?

MOUSAVIAN: During past 15 years, working at Princeton University as academic with my experience of 40 years working on Iran-U.S. relations, advocating peace between Iran and U.S. relations, I have explained in my books, in many articles, that more sanctions, more pressures, more coercion would radicalize Iran more and more and more. And this is exactly when the U.S. withdrew from the nuclear deal and imposed sanctions, Iran increased the level and the capacity of enrichment. And now the U.S. attacked Iran – I think it’s normal when a country is attacked, the military would take over the country practically.

MA: You refer to the earlier nuclear negotiations, and it’s believed that Iran has a stockpile of about 400 kilograms of enriched uranium. What do you think will happen to that stockpile?

MOUSAVIAN: See, I mean, here is the reality that during negotiations between the U.S. representative – Witkoff, Kushner – with Iranian representative in February 2026, the Iranian negotiator very clearly explicitly told the American side, if there is a deal, we would be ready to dilute the whole high-level enriched uranium 60%. We will be ready to give it up. This was mentioned officially in the – by the Oman foreign minister. Even lately – I don’t know whether you read the article at The Guardian – the U.K. National Security Advisor attended in the last meeting, February 2026, just this year, and he also confirmed that Iran was ready to give up the total 60% of stockpile enriched uranium. Therefore, if there is a deal, Iran has no problem. Iran is not going to keep it.

MA: Though a deal does seem hard to imagine at this particular moment, do you think there’s still room for diplomacy, given that the U.S. started this war in the middle of what were apparently productive negotiations?

MOUSAVIAN: Frankly speaking, that would be very difficult, complicated because the U.S. attacked Iran. As the Omani foreign minister said, there was two times negotiation with significant progress. They were very close to reach a deal, but the U.S. decided to attack. Therefore, trust is gone. Nevertheless, I don’t believe that the door for diplomacy is totally closed, nevertheless. I really don’t know what type of deal the U.S. is looking for with Iran. You heard Prime Minister Netanyahu saying the Israeli strategy is greater Middle East. You heard American ambassador in Israel said, Israel has a right to take over the Middle Eastern countries. And I really don’t know if this is really the objective – regime change, taking over Iranian oil, wealth – never there would be a deal.

MA: We’ve been speaking with Hossein Mousavian, former Iranian nuclear negotiator. Thank you so much for taking the time.

MOUSAVIAN: Thank you very much.

‘Tehran can manufacture missiles even during wartime” — What a former Iranian nuclear negotiator reveals to Parapolitika’

By Seyed Hossein Mousavian

Interview with Parapolitika, Greece, March 22, 2026.

Interview- Yanni Moutsios with Mousavian, Parapolitika newspaper / MEGA NEWS TV

  1. Ambassador Mousavian, Operation Epic Fury is already underway. Iran has warned that states assisting Western forces will face retaliation. Does that now include Arab countries that have traditionally maintained friendly relations with Tehran?

Iran had already conveyed to its neighbors before the war that if the United States attacked Iran, Tehran would retaliate by targeting U.S. military bases in the region. Since many of those bases are located in Arab countries in the Persian Gulf, Iran argues that any strikes there are directed at U.S. forces rather than against the host countries themselves. Iranian officials have repeatedly stated that if regional states allow their territory or facilities to be used for attacks on Iran, those locations could become legitimate targets in a retaliatory response. However, while Iran insists it seeks to maintain friendly relations with its neighbors and frames its actions as self-defense against the United States, the countries do not accept that justification and view attacks on their territory as violations of their sovereignty.

  1. Iran has launched missile and drone strikes since the operation began. How long can Iran realistically sustain this level of retaliation? Weeks, months, or longer? Critics say Iran’s missile arsenal is large but not unlimited. At what point would Iran risk be exhausting its strategic capabilities if this conflict drags on?

According to Iranian military statements, retaliation could continue for at least six months. However, the more objective assessment is that the sustainability depends on two factors: existing stockpiles and production capacity. Iran is largely self-sufficient in missile and drone production and can continue manufacturing during wartime, including through dispersed and underground facilities. Estimates suggest Iran possessed thousands of ballistic missiles before the current conflict, with production rates ranging from dozens to over 100 missiles per month depending on the system. This means Iran can continue producing missiles 24/7 even during the war, which allows it to replenish some losses. However, high-intensity barrages cannot be sustained indefinitely because consumption in major salvos can exceed monthly production.

  1. If the war intensifies, will Iran expand its target list to include energy infrastructure, shipping lanes, or civilian economic assets in the region?

Iran’s stated military approach is largely based on reciprocity. Iranian officials have indicated that the nature of Iran’s response would mirror the actions taken by the United States or Israel. If attacks are limited to military targets, Iran is likely to respond in a similar manner. However, if Iranian energy infrastructure, economic facilities, or civilian assets are targeted, Tehran has signaled that it would respond in kind. In such a scenario, Iran could expand its target list to include regional energy infrastructure, oil and gas facilities, and strategic shipping routes, particularly in and around the Persian Gulf and the Strait of Hormuz. These areas are critical to global energy flows and lie close to Iran, making them vulnerable during an escalatory conflict. In essence, Iran’s strategy suggests that escalation would likely be symmetrical: attacks on Iranian economic or energy infrastructure would likely trigger retaliatory strikes against comparable regional economic assets and maritime routes.

  1. We have already seen strikes affecting neighboring states. Is Iran prepared for the possibility that countries like Azerbaijan, Turkey, Iraq, or Pakistan could be pulled directly into this conflict?

Iran’s stated policy is to avoid confrontation with neighboring countries and to preserve good relations with them, including states such as Azerbaijan, Turkey, Iraq, and Pakistan. Iranian officials argue that their military responses are directed at U.S. or Israeli military assets, not at the host countries themselves. Tehran’s expectation is that neighboring governments will not allow their territory, airspace, or military facilities to be used for attacks against Iran; if such attacks originate from those locations, Iran says it reserves the right to respond against the attacking forces there. At the same time, Iranian leaders have emphasized that they do not seek to expand the war or draw neighboring states into the conflict and have even apologized for incidents affecting nearby countries, stressing that Iran wants to maintain friendly and stable relations with the region

  1. There is growing speculation about the next phase of the operation. Do you believe the United States would risk sending ground forces into Iran?

At this stage, a large-scale U.S. ground invasion of Iran appears unlikely, although it has not been completely ruled out by President Donald Trump. Most military assessments suggest Washington will rely primarily on-air power, naval forces, and other forms of pressure rather than committing to a massive ground war in a country as large and difficult to occupy as Iran. At the same time, the political calculations may be evolving. The initial expectation in Washington and Tel Aviv was that the operation would bring Iran to the brink of collapse within 48 hours, but Iran’s military responses have proven far stronger and more sustained than many anticipated. As a result, if the conflict continues to escalate without achieving its original objectives, it is possible that Trump could look for an off-ramp and announce a ceasefire or pause in operations while claiming that the main strategic goals of the campaign have been achieved.

  1. If that happened, could Washington try to work with Kurdish militias or other internal groups to destabilize the Iranian government from within?

It is often speculated that Washington could try to rely on Kurdish militias or other internal groups to destabilize the Iranian government, but such a strategy would face serious limitations. Using Kurdish forces would not only risk destabilizing neighboring countries like Turkey, Syria, and Iraq—where Kurdish issues are already highly sensitive—but could also create wider regional instability. Moreover, the situation of Kurds in Iran is different from some other parts of the region. Kurds are historically part of the broader Iranian civilizational sphere, and Iranian Kurds generally see themselves as part of Iran’s national fabric. For these reasons, it is unlikely that Iranian Kurds would support a foreign-backed effort to undermine the Iranian government, and any attempt to instrumentalize Kurdish groups could easily backfire both inside Iran and across the region.

  1. And if foreign troops did enter Iranian territory, what would Iran’s military response look like?

If foreign troops were to enter Iranian territory, Tehran’s military response would aim to turn any such intervention into a protracted and costly conflict for the invaders, much as the United States experienced in Vietnam and later in Afghanistan, where local resistance and difficult terrain led to drawn‑out wars that wore down foreign forces. Iranian military doctrine and statements by senior commanders have emphasized that any incursion into Iran’s sovereign territory would be met with sustained and widespread resistance using a combination of conventional forces, missile and drone strikes, and asymmetric tactics, making occupation extremely difficult and costly for any foreign power

  1. Some Western officials say the ultimate objective of this operation could be political change in Tehran. Do you believe regime change is actually part of the strategy?

While some Western officials frame the U.S. objective as promoting political change in Tehran, the broader regional context suggests multiple overlapping goals. Israeli leaders have consistently stated that their strategic aim is to weaken or disintegrate Iran to advance what they call the Greater Israel Agenda. (timesofisrael.com) From Washington’s perspective, senior officials have indicated that controlling Iran’s oil reserves is a central objective of the military campaign. In practice, this translates into a strategy aimed at undermining the current government, echoing patterns seen in the 1953 coup against Prime Minister Mossadegh, when the United States sought to replace Iran’s leadership to secure control over energy resources. (history.state.gov) Thus, while the rhetoric emphasizes political change, U.S. action reflect longstanding strategic and economic interests .

  1. Would Iran consider giving up its ballistic missile program or curtailing its nuclear ambitions to end the war? Iran remains a signatory to the Nuclear Non-Proliferation Treaty, but the country is now under direct military pressure. Could this conflict push Iran to rethink the limits of its nuclear program?

Iran’s leadership has long made clear that it will not agree to give up its ballistic missile capabilities or curtail its peaceful enrichment of uranium even to end a war, because Tehran views both as essential to deterring foreign invasion and preserving the country’s integrity. Iranian officials have repeatedly stated that the missile program is “non‑negotiable” and rooted in national defense, framing it as necessary to prevent any repetition of scenarios like Gaza or other foreign interventions, and they have refused to pause enrichment despite external pressure. From Tehran’s perspective, without its missile deterrent and nuclear advances, the risk of external powers seeking regime change or further strikes would only increase, so it would not be prepared to trade away those core defense capabilities to secure a ceasefire.

  1. Iran’s Assembly of Experts has appointed Mojtaba Khamenei as the country’s Supreme Leader. President Trump stated that he should have a say in the selection of Iran’s new leader and issued a threat of assassination if his demand was not met. What is your opinion on this situation?

The assassination of the previous Supreme Leader, Ayatollah Ali Khamenei, was a grave violation of international rules and norms. Following his killing, Iran’s constitutional body, the Assembly of Experts, appointed Mojtaba Khamenei as the new Supreme Leader during wartime conditions. Statements suggesting that the United States should decide who leads Iran, or threatening assassination if such demands are not met, would also be seen as clear violations of international law and Iran’s sovereignty. The decision by the Assembly of Experts sends a strong message that Iran, with thousands of years of history and civilization, will not accept foreign dictates over its leadership or political system. In my view, rather than relying on military strikes, assassinations, or threats, the wiser course for Washington would be to pursue diplomacy and seek a resolution with Iran based on mutual respect, mutual interests, and non-interference in each other’s internal affairs.

  1. Ambassador Mousavian, from Tehran’s perspective, what would it take to force Western governments to stop Operation Epic Fury?

From Tehran’s perspective, the continuation or end of Operation Epic Fury will largely depend on Iran’s ability to withstand U.S. and Israeli military pressure while maintaining the country’s territorial and political integrity. Iranian officials argue that if Iran successfully resists aggression and demonstrates that foreign forces cannot impose their objectives by force, Western governments will be compelled to reconsider their approach. Rather than achieving regime change, the West would then be forced to negotiate with Iran on terms of mutual respect, shared interest, and non‑interference, recognizing that sustainable compromise can only occur when Iran’s sovereignty and national resilience are fully acknowledged.

Interview, “Iran Has Adapted, Not Collapsed… U.S. ‘Five-Day Delay’ Is a Tactical Decision”,

By Seyed Hossein Mousavian

Interview with Hankookilbo newspaper, South Korea, 2026.03.25

Despite the challenges of wartime conditions, Iran’s decision-making system remains cohesive, operational, and has adapted to the realities of war. Despite heavy losses among senior leadership and intense airstrikes, the country’s top political and military structures remain intact, with key institutions—including the presidency, parliament, and the IRGC—continuing to coordinate and respond effectively. Iran’s defensive doctrine, known as “mosaic defense,” was specifically designed for such circumstances: even if top leadership or central command is struck, regional and local units retain the authority and capability to act independently. As a result, both cohesion and operational intensity appear to have been reinforced during the conflict.

The theory that Iran would collapse under military attack represents a major strategic miscalculation by the United States. Iran’s leadership views the U.S.–Israel war as an existential threat. The assumption that external pressure alone could trigger internal collapse is deeply flawed. Iran is not Venezuela or Syria; it possesses a long history and civilization, a strong national identity, established institutions, and significant social cohesion that make capitulation unlikely. With the onset of military confrontation, public attention has shifted from domestic grievances to national defense, producing a deeply rooted pattern of unity in response to what is perceived as foreign aggression—an essential reality policymakers must take into account.

Trust in the United States has sharply declined in Tehran. Trump’s shift—from threatening attacks on Iranian power facilities to announcing a five-day delay and signaling openness to a deal—appears largely tactical. The war began abruptly in the midst of nuclear negotiations that had made meaningful progress, further eroding confidence. For the five-day pause to yield substantive results, significant obstacles must be overcome. President Trump would need to demonstrate greater consistency and credibility in both rhetoric and policy, reduce contradictions, and take concrete steps to rebuild at least minimal trust.

From Tehran’s perspective, the underlying objectives of its adversaries go beyond the nuclear issue. Iranian leaders believe these goals include advancing a “Greater Israel” strategy through the weakening or fragmentation of Iran, alongside regime change and U.S. control over Iran’s oil and strategic resources. Under sustained military pressure aimed at forcing capitulation, Iran is likely to become more radicalized, increasing the risk of escalation into a broader and potentially uncontrollable regional war. While Iran has restricted maritime traffic in the Strait of Hormuz, it has so far refrained from fully closing it, preserving this option as a tool of pressure pending credible security guarantees.

Interview with The Open: “Khamenei was not only a politician, but a religious leader. Trump has miscalculated; he risks a long war”

The Open, Italy

Interview with Seyed Hossein Mousavian

March 4 2026

According to the diplomat, who led nuclear negotiations in the past, the killing of the ayatollah risks responses from other Muslim countries as well. A Venezuelan-style solution is impossible

“History teaches us that interventions designed to ensure stability often produce decades of unpredictable consequences.” Hossein Mousavian led the Iranian delegation in the nuclear negotiations in the 2000s. Today, he tells Open, he is very worried about what he calls “an existential war” for his country. Sixty-nine years old, former ambassador of Tehran to Germany, for twenty years a trusted man of the regime, Mousavian arrived in the United States in 2009 with a conviction for espionage on his head. In America he found a home at Princeton University, where he taught until last June when a campaign carried out by some colleagues and politicians – who accuse him of still being close to the regime – pushed him to retire. Accusations that the former diplomat has always rejected, stating that he is working “for dialogue between the two countries”.

Professor, what do you mean by “existential war”?
“By declaring that the goal is the collapse of the regime, it was the United States that framed the conflict as existential. Iran’s response is experienced internally by many as a defense of national survival. But there is more. With the assassination of Supreme Leader Ali Khamenei, the United States and Israel have crossed a red line. The consequences go far beyond the killing of a political leader: Khamenei was one of the main religious authorities in the Shiite world. His figure has theological importance, not only political. Some Shiite leaders have already launched calls for retaliation. Ayatollah Naser Makarem Shirazi, in Qom, declared that avenging Khamenei is a religious duty for all Muslims in the world, to eliminate the evil of these criminals from the face of the earth.

Why did Trump decide to attack right now?
“Many American officials have confirmed that it was Netanyahu who pushed Trump. But the timing is significant: both the June 2025 attacks and the February 28, 2026 attack took place at a time when nuclear negotiations – according to Oman’s foreign minister, who acted as mediator – had achieved significant progress. It was then Trump himself who admitted that the goal is regime change in Iran.”

Many have thought of a “Venezuelan” solution: cooperation with the apparatus in exchange for an end to the nuclear program and reforms for the oppressed population. Do you see it as possible?
“With Iran’s counter-attack on Israel and American bases in the region, I believe that the United States has already realized that a Venezuelan solution is impossible.”

Has the Trump administration underestimated Iran’s ability to respond?
“He made three errors of judgment. First: they underestimated the consequences of the killing of Khamenei, a Shiite religious leader worldwide. This will have repercussions far beyond Iran’s borders. Second: the Iranian military response. For the first time since World War II, major U.S. military bases in the region have been the subject of sustained attacks. The impact on American prestige could even outweigh the symbolic damage of the 1979 hostage crisis. Third: they believed that military force was enough. But force can destroy infrastructure and eliminate individuals, it cannot erase national identity, religious conviction or historical memory. The lessons of 1953, the US-backed coup, still resonate in Iran today.”

Netanyahu has always described Iran as the “existential threat” to Israel.
“Israel is facing the most intense attacks on the territory since its founding in 1948. Iran’s missile counter-offensive is threatening Israel’s security architecture, despite advanced defense systems. The perception of invulnerability – central to Israeli deterrence – has been shaken. Iran has suffered considerable military damage, but both sides have found themselves more fragile than they thought.”

How long can Iran resist? And how likely is it that the conflict will spread further?


“The war has already spread to the regional level and the trajectory is alarming: escalation generates counter-escalation because each side justifies its actions as defensive. The risks of miscalculation grow with each trade. Markets are on alert, regional players are being dragged in, diplomatic space is shrinking. It would be wiser for Trump to push for an immediate ceasefire, before it becomes impossible to contain the conflict. The longer it continues, the harder it will be to stop it.”

Op-ed: US-Israeli strikes can raze buildings, but they cannot extinguish Iranian identity 

Middle East Eye, March 3nd 2026

* Military force can destroy infrastructure and eliminate individuals, but it cannot extinguish national identity, religious conviction or historical memory. The lessons of 1953 still resonate. If history teaches anything, it is that interventions intended to secure stability often produce decades of unintended consequences.

* Both the US-Israeli military strikes on Iran in June 2025, and the attack in February 2026 occurred at moments when negotiations had achieved significant progress, according to Oman’s foreign minister.

* By officially declaring that its objective is regime collapse, the US framed the conflict as existential. Iran’s response is thus perceived domestically as a defence of national survival. 

* The choice now is stark: continue down a path of open-ended confrontation, or halt the escalation and return to diplomacy – before the damage becomes irreversible

* It would be wiser for US President Donald Trump to push now for an immediate ceasefire, to prevent further catastrophe. The longer this conflict continues, the harder it will be to contain.

Of Bombs and Regime Change: Experts Weigh the Israel-U.S. Strategy on Iran – The Cairo Review of Global Affairs

Interview with Mousavian

Cairo review, March 1, 2026

As of now, most countries around the world believe that the military attack by the United States and Israel constitutes a clear violation of the UN Charter and the norms and regulations of international law.

In 2018, the United States undermined a UNSC-Resolution 2231 by withdrawing from the JCPOA; in 2025-2026, through direct military strikes against Iran, it has been accused of violating core principles of the UN Charter, particularly those related to sovereignty, the prohibition of the use of force, and non-interference in internal affairs of other countries.

According to Oman’s foreign minister, both the U.S.–Israeli military strike on Iran in June 2025 and the subsequent attack in February 2026 occurred at moments when negotiations had reportedly achieved significant progress. As Oman served as a mediator, this statement implies that Washington bombed diplomacy at critical junctures. From this perspective, diplomacy has effectively been placed in the critical care unit, perhaps for an indefinite period, as many countries now believe that the negotiations were conducted not as a genuine path to compromise but as a strategic instrument.

The consequences of assassinating Ayatollah Khamenei could go beyond the killing of a head of state. He was one of the leading religious authorities (marajiʿ) in the Shiite world, and the U.S. action could be interpreted as a declaration of war against Shiite religious authorities. Consequently, some Shiite clerics have already issued fatwas of jihad and have called on Muslims around the world to avenge the assassination of Ayatollah Khamenei by targeting the United States and Israel. Attacks have taken place against U.S. diplomatic missions in Pakistan and Iraq, and dozens of Shiites have been killed or injured. Washington must therefore be concerned about a long-term ideological hostility from religious Shiites across the globe.

The collapse of the government in Iran as a result of military attack is not a simple matter. Even assuming that the United States and Israel succeed in bringing about regime change, they would still be the losers. Because:

  1. For the first time since World War II, the most important U.S. military bases have come under attack—a reputational blow to the United States’s prestige far greater than the hostage-taking of American diplomats in Iran.
  2. Israel and Iran have entered an existential phase of conflict. Iran has sustained severe military blows, while Israel has faced the most intense military attacks on its territory since World War II. Iran’s heavy missile strikes against Israel have exposed the fragility of Israel’s military and security structures.

Following the assassination of Iran’s leader, within less than 48 hours a three-member leadership council was formed in accordance with the constitution, and the next leader of Iran will be appointed by the Assembly of Experts.

With the second U.S. and Israeli military attack, several significant and troubling developments have occurred. First, by assassinating Iran’s leader, the United States crossed a red line of Iran’s current system of governance. Second, the United States officially declared that its objective is the collapse of the Iranian government; therefore, Iran’s response is framed as a defense of its very existence. Third, it was already clear that the conflict would become regional—which it has—and Iran has launched missile attacks against U.S. facilities in the region.

Ultimately, it would be better for President Trump to take the initiative for an immediate ceasefire in order to prevent further catastrophes.

Princeton University host Seyed Hossein Mousavian public lecture on the June 2025 US attacks on Iran and future of US-Iran relations

December 8, 2025

Princeton University’s Program on Science and Global Security (SGS) together with the Princeton School of Public and International Affairs (SPIA) hosted a public lecture Reflections on the June 2025 US Attacks on Iran: Causes, Consequences, and the Future of US-Iran Relations by Seyed Hossein Mousavian.

The lecture was introduced by Frank von Hippel, who co-founded SGS in 1974 and served as its co-director for its first 30 years, and is now a professor emeritus at Princeton University. von Hippel recruited Seyed Hossein Mousavian to join SGS in 2010. Mousavian was on the SGS research staff for 15 years as a Middle East Security and Nuclear Policy Specialist before he retired in May 2025.

In the lecture, Mousavian took as his starting point the Twelve Day War of June 2025 in which Israel and U.S. attacked Iran’s nuclear facilities, and which led to relations between Washington and Tehran entering their most dangerous and decisive period since the Iranian Revolution of 1979. The lecture explored three central questions: why did the U.S.–Iran relationship reach this crisis point, what have been the consequences so far, and what steps can be taken to prevent further war and lay a foundation for peace. As Washington and Tehran reassess their strategies amid a shifting balance of power in the Middle East, Mousavian offered his view on whether a new US-Iran nuclear deal was possible and the regional and global implications if no deal could be reached. 

Mousavian is the author of six books, including “A Middle East Free of Weapons of Mass Destruction” (2020), “Iran and the United States, An Insider’s View on the Failed Past and the Road to Peace” (2014), and “Iranian Nuclear Crisis, A Memoir” (2012). He is currently working on a book on the rise and fall of the Iran nuclear deal.

Mousavian originally trained as an industrial engineer in Iran and later earned a PhD in international relations from the University of Kent, United Kingdom and went on to have career as an Iranian government official and a scholar. As a diplomat, he served as Iran’s Ambassador to Germany (1990-1997), and as Head of the Foreign Relations Committee of Iran’s National Security Council (1997-2005), Spokesman for Iran in its nuclear negotiations with the international community (2003-2005), Foreign Policy Advisor to the Secretary of the Supreme National Security Council (2005-2007), Vice President of the Center for Strategic Research for International Affairs (2005-2009), General Director of Foreign Ministry for West Europe (1987-1990), He was Chief of Parliament Administration (1984-1986) and the editor-in-chief of the English-language international newspaper Tehran Times.
