Nuclear Weapons

US Secretary of State Marco Rubio has said that talks with Iran are under way through intermediaries and that Washington will continue its military campaign until Tehran abandons its nuclear and missile programmes.

He warned on Monday that the Strait of Hormuz will be kept open “one way or another” and that US war objectives could be achieved “in weeks, not months”.

He also said the United States would welcome political change in Iran if the opportunity arose, but said it was not an official objective. Rubio criticised some NATO allies for refusing US access to bases during the war, and said Washington is closely watching developments in Cuba and Venezuela.

Here are the key takeaways from Rubio’s exclusive interview with Al Jazeera’s Hashem Ahelbarra:

Marco Rubio says talks with Iran are happening

Much of the communication between Tehran and Washington is indirect and through intermediaries, but Rubio insisted that it is ongoing.

He said there are “messages and some direct talks going on between some inside of Iran and the United States, primarily through intermediaries”, adding that the US president “always prefers diplomacy, always prefers an outcome”.

His comments come as US President Donald Trump escalated his rhetoric on social media, threatening to “obliterate” Iran’s energy infrastructure if a ceasefire is not reached soon, Al Jazeera’s Kimberly Halkett reported from Washington.

“Taken together, Rubio’s statements and Trump’s posts suggest the US is pursuing a dual-track approach: keeping diplomatic channels open through intermediaries while simultaneously increasing military and economic pressure on Iran,” she said.

US demands Iran abandon nuclear and missile programmes

Rubio said Iran must abandon its nuclear weapons ambitions and stop producing missiles and drones that can threaten countries across the Gulf region, and insisted “The Iranian regime can never have nuclear weapons.”

He said Iran’s missile programme poses a direct threat to countries across the Gulf, and claimed “These short-range missiles that they’re launching, they only have one purpose, and that is to attack Saudi Arabia and the UAE and Qatar and Kuwait and Bahrain.”

Rubio said Iran could pursue civilian nuclear energy, but not in a way that would allow it to quickly develop a nuclear weapon.

“What they cannot have is a system that allows them to quickly weaponise it,” he said. “They have to abandon all these weapon programmes and all their nuclear ambitions.”

However, Hassan Ahmadian, an assistant professor at the University of Tehran, questioned the narrative that Iran poses an offensive threat in the region.

“When was the last time Iran attacked its neighbours over three centuries?” Ahmadian asked, arguing that Iran’s military strategy is shaped by deterrence in an asymmetric conflict.

“Why is it doing this now? Because it’s the underdog in an asymmetric war that it wants to shield itself by expanding.”

Ahmadian added that Iran has been a central focus of US policy for years.

“With the break of two wars in less than a year, we have experienced, Iran has been on the table in different US administrations – all options are on the table,” he said.

Strait of Hormuz will be kept open ‘one way or another’

Rubio said the US would not accept Iran claiming sovereignty over the Strait of Hormuz and warned that the waterway would remain open regardless of Iran’s actions.

“Not only is the sovereignty over the Strait of Hormuz not acceptable to us, it won’t be acceptable to the world.”

“It sets an incredible precedent … nations can now take over international waterways and claim them as their own.”

“The Strait of Hormuz will be open … It will be open one way or another,” he said, adding that otherwise, Iran would “face real consequences” from the US and other countries.

Iranian analysts suggested the closure of the strait is a temporary wartime measure and could be reversed once the conflict ends.

“It’s opened partially,” Ahmadian said, adding “I think there is no Iranian interest to not open it beyond the war.”

“It’s an asymmetric way of putting pressure on Americans, just as they are bombing Iran, and so after the war there would be no need,” Ahmadian explained. “There will be an arrangement, according to the Iranians, with the GCC [Gulf Cooperation Council] countries to reopen it and see how things are managed.”

War objectives will be achieved ‘in weeks, not months’

Rubio said the US military campaign is progressing quickly and outlined the military objectives Washington is trying to achieve.

“Those objectives are the destruction of their air force, which has been achieved, the destruction of their navy, which has largely been achieved.”

“A significant reduction in the number of missile launchers… and we are going to destroy the factories that make those missiles and those drones.”

“We are well on our way or ahead of schedule.”

“We will achieve them in weeks, not months.”

“That’s a matter of weeks. I’m not going to tell you exactly how many weeks, but a matter of weeks, not months.”

Rubio says status of Iran’s new supreme leader is uncertain

Asked by Al Jazeera about his thoughts on Iran’s new Supreme Leader, Mojtaba Khamenei, Rubio said his status remains unclear.

“We don’t even know he’s in power. I know they say he’s in power. No one has seen him. No one has heard from him,” Rubio said.

“It’s very opaque right now. It’s not quite clear how decisions are being made inside of Iran.”

Iran’s leadership change is not an objective of the military operation

The US secretary of state suggested the US would welcome political change in Iran, though he said it was not the official objective of the military operation.

“We would always welcome a scenario in which Iran was led by people that had a different view of the future,” Rubio said. “If that opportunity presents itself, we’re going to take it.”

He said the Iranian people “deserve better leadership” and indicated Washington would not oppose a change in government if it occurred.

“Do we think the people of Iran deserve better leadership than what they’ve gotten from the clerical regime? One hundred percent,” Rubio said. “Would we be heartbroken if there was a change in leadership? Absolutely not.”

He also suggested the US would be willing to play a role if political change became possible.

“If there’s something we could do to facilitate that, would we be interested in participating? Of course.”

However, analysts said Washington’s position on regime change appears to have shifted over time.

“Originally bringing down the government was the goal; there has been a constant drawdown from that,” Paul Musgrave, a professor of government at Georgetown University in Qatar, told Al Jazeera.

“And now we have President Donald Trump on Truth Social saying he is negotiating with elements of what could become a new regime, so there is a lot of confusion here, but it is no longer the number one goal. It’s not something they are laying out,” he noted.

Rubio criticises NATO allies and warns alliance may be reviewed

Rubio said some NATO countries denied the US use of airspace and bases during the conflict and suggested Washington may need to reassess the alliance after the war.

“We have countries like Spain, a NATO member that we are pledged to defend, denying us the use of their airspace and bragging about it, denying us the use of their bases.”

“And so you ask yourself, well, what is in it for the United States?”

“If NATO is just about us defending Europe from attack, but them denying us basing rights when we need them, that’s not a very good arrangement.”

“All of that is going to have to be re-examined.”

Israel has been trying to make the case for its war on Iran by portraying the country as a threat to European cities, warning Iranian missiles could reach capitals like London and Paris.

Former NATO official William Alberque says 440 kg of missing Iranian uranium is blocking a US victory claim. He warns that despite strikes on Natanz Nuclear Facility, the risk of proliferation remains.

An Iranian missile has struck the southern Israeli cities of Dimona, home to the country’s main nuclear facility, and nearby Arad, wounding dozens of people and causing significant damage, in one of the most dramatic escalations since the US-Israel war on Iran began.

Iranian state television quickly reframed Saturday’s strikes as a “response” to what it said was a strike on Iran’s Natanz nuclear enrichment complex earlier in the day, marking a stark new phase of tit-for-tat targeting in the conflict, now in its fourth week.

Nearly 100 people were wounded in the attacks, according to Israel’s emergency services, including a 10-year-old boy who paramedics said was in critical condition with multiple shrapnel wounds. Seven others are also in critical condition.

An Israeli military spokesman said Israel’s air defence systems activated during the attacks, but failed to intercept some of the missiles, even though they were not “special or unfamiliar”.

The country’s Prime Minister Benjamin Netanyahu, addressing the attacks which wounded nearly 100 people, called it a “difficult” evening for Israel, and again vowed to continue attacking Iran.

The International Atomic Energy Agency (IAEA) said it had received no indication of damage to the Shimon Peres Negev Nuclear Research Center at Dimona itself, and that no abnormal radiation levels had been detected in the area.

The nuclear watchdog said it was closely monitoring the situation, with Director General Rafael Grossi urging that “maximum military restraint should be observed, in particular in the vicinity of nuclear facilities”.

Al Jazeera’s Nour Odeh, reporting from Ramallah in the occupied West Bank, said that three separate impact sites had been identified across Dimona, with one three-storey building having completely collapsed and several fires breaking out.

Witness footage verified by Al Jazeera, which is banned from operating inside Israel, showed a missile striking the city, followed by a large explosion.

Arad, another town near the nuclear facility, was also directly attacked, Israel’s firefighting service said in a statement, with extensive damage reported in the city centre.

“In both Dimona and Arad, interceptors were launched that failed to hit the threats, resulting in two direct hits by ballistic missiles with warheads weighing hundreds of kilograms”, firefighters said.

School in the surrounding Ramat Negev Regional Council was cancelled for the following day.

Earlier on Saturday, the Israeli military announced it had struck a research and development facility at Tehran’s Malek Ashtar University, which it said had been used to develop components for nuclear weapons and ballistic missiles.

The military said it “will not allow the Iranian regime to acquire nuclear weapons”.

Iran said that the US and Israel had targeted its Natanz enrichment complex that morning, though it reported no radioactive leakage.

An unnamed Israeli official, quoted by the Associated Press news agency, denied that Israel was responsible for the Natanz strike, but the Israeli army has not released a full statement on the matter.

Dimona has been at the heart of Israel’s nuclear programme since its research centre, built in secret with French assistance, opened there in 1958.

Eye-for-an-eye approach

Israel is believed to have developed nuclear weapons by the late 1960s. Its policy of deliberate ambiguity, neither confirming nor denying their existence, was part of a deal quietly struck with Washington, which judged that an open declaration would risk triggering a regional arms race.

Abas Aslani, a senior fellow at the Centre for Middle East Strategic Studies in Tehran, told Al Jazeera that Iran has been pursuing an eye-for-an-eye approach designed to re-establish deterrence.

“Tehran wants to reduce the gap between words and actions,” he said, adding that Iran’s goal was to make its threats credible enough to underpin a new long-term security arrangement, not to simply force a ceasefire, but establish deterrence.

The attacks came as the broader war grinds through its fourth week.

More than 1,400 people have been killed in Iran since the US and Israeli strikes began on February 28, including more than 200 children.

Iran has retaliated across the region, launching what it described as its 70th wave of attacks on Saturday, targeting Israeli and US military positions, as millions of Iranians marked the Persian New Year, Newroz, and Eid al-Fitr under the shadow of war.

US President Donald Trump has reacted to the resignation of the US National Counterterrorism Centre’s director, Joe Kent, saying that he couldn’t work with somebody who didn’t believe Iran was a threat. Trump also said his decision to bomb Iran avoided a ‘nuclear holocaust’.

Offering another rationale for the US-Israeli war on Iran, Donald Trump claimed he ordered strikes to prevent a nuclear conflict that would have turned into World War III. He also said not even the “greatest experts” thought Iran would retaliate with attacks on Gulf states.

North Korea’s Kim Yo Jong said the annual ‘Freedom Shield’ exercises could lead to ‘unimaginably terrible consequences’.

Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, has accused the United States and South Korea of “destroying the stability” of East Asia, as the two countries start their annual 10-day joint military exercises on the Korean Peninsula.

“The muscle-flexing of the hostile forces near the areas of our state’s sovereignty and security may cause unimaginably terrible consequences,” Kim Yo Yong said on Tuesday, according to the state-run Korean Central News Agency (KCNA).

“The enemies should never try to test our patience, will and capability,” Kim said.

“We will watch to what extent the enemy violates the security of our state and what it is playing at,” she continued.

Kim’s remarks follow the start of the joint Freedom Shield exercises on Monday, which will run for 10 days and involve 18,000 South Korean and US military personnel.

The military manoeuvres are designed to “enhance the combined, joint, all-domain, and interagency operational environment, thereby strengthening the Alliance’s response capabilities,” United States Forces Korea said.

This year’s Freedom Shield will involve 22 field training drills, according to South Korea’s Yonhap News Agency, which is fewer than half the number carried out last year.

Kim added on Tuesday that there was no justification to hold the exercises, which have been called a “defensive” action by Washington and Seoul in the past.

“No matter what justification they may establish and how the elements of the drill may be coordinated, the clear confrontational nature of the high-intensity large-scale war drill staged by the most hostile entities in collusion at the doorstep of [North Korea] never changes,” she said.

“The recent global geopolitical crisis and complicated international events prove that all military manoeuvres of the field warfare troops, to be conducted by the enemy states, assume no distinction between defence and attack, training and actual warfare,” she continued, in an apparent reference to the US-Israel war on Iran.

South Korea and North Korea have technically been at war since 1953, when an armistice agreement paused fighting but did not formally end the armed confrontation.

North Korean leader Kim Jong Un said in 2024 that he would no longer pursue reconciliation with South Korea, although it remains Seoul’s long-term goal.

An official at South Korea’s Ministry of Unification told Yonhap that Kim’s remarks on Tuesday were relatively muted by North Korean standards.

The statement did not refer directly to the US or threaten to use nuclear weapons, the official said, speaking on condition of anonymity.

“Kim appears to have limited her response to merely pinpointing the South Korea-US exercise, taking the current security situation into account,” the official told Yonhap.

Kim Jong Un supervised the launch of sea-to-surface ‘strategic cruise missiles’ from country’s new naval destroyer.

North Korean leader Kim Jong Un has overseen the test-firing of “strategic cruise missiles” from a new 5,000-tonne naval destroyer before the vessel’s official commissioning, according to state media.

Kim supervised the launch of sea-to-surface missiles from the destroyer Choe Hyon on Wednesday, assessing the test as a “core” element of the new warship’s capabilities, which he described as a “new symbol of sea defence” for his country.

Calling for the production of more warships of a similar class or better, Kim said his navy’s adoption of nuclear weapons was making progress.

“Our Navy’s forces for attacking from under and above water will grow rapidly. The arming of the Navy with nuclear weapons is making satisfactory progress,” Kim said at the Nampo Shipyard in the west of the country, according to North Korea’s official Korean Central News Agency (KCNA).

“All these successes constitute a radical change in defending our maritime sovereignty, something that we have not achieved for half a century,” he said.

South Korea’s official Yonhap news agency noted that North Korea uses references to “strategic” weapons to indicate they could have nuclear capabilities.

According to KCNA, over a two-day visit to the shipyard, spanning Tuesday and Wednesday, Kim inspected the Choe Hyon, the lead vessel in a new series of 5,000-tonne “Choe Hyon-class” destroyers currently under construction in North Korea.

‘Wage a more active and persistent struggle’

In May 2025, North Korea’s ambitious naval modernisation programme suffered a major setback when a second Choe Hyon-class destroyer capsized during a botched side-launch ceremony at Chongjin Shipyard, an incident witnessed by the Korean leader.

Later, and in a rare admission of failure, KCNA reported that a launch mechanism malfunction caused the stern of the 5,000-tonne destroyer to slide prematurely into the water. The accident crushed parts of the hull and left the bow stranded on the shipway.

At the time, Kim characterised the launch failure as a “criminal act”, blaming the incident on “absolute carelessness” and “irresponsibility” across multiple state institutions.

This week’s missile tests come after the North Korean leader pledged in late February to lift living standards as he opened a rare congress of the governing Workers’ Party, held once every five years.

Kim told the congress that the ruling party was “faced with heavy and urgent historic tasks of boosting economic construction and the people’s standard of living”.

“This requires us to wage a more active and persistent struggle without allowing even a moment’s standstill or stagnation,” he said.

North Korea has prioritised nuclear weapons development and military strength above all else, claiming that it must be militarily strong to resist pressure from the United States and its ally, South Korea.

Since taking power in late 2011, Kim has maintained the military as a core priority while simultaneously emphasising economic strengthening to address the country’s chronic impoverishment.
