The Iranian regime’s retention of key nuclear weapons facilities and its material for building atomic bombs — highly enriched uranium — has led to new efforts by the U.S. and Israeli militaries to take out the last vestiges of the regime’s program.

On Friday, the Israel Defense Forces (IDF) said in a statement that, that it’s “Air Force Struck the Arak Heavy Water Plant—A Key Plutonium Production Site for Nuclear Weapons.” The Arak plant is located in central Iran.

Prior to Friday’s attack, an IDF spokesperson told Fox News Digital concerning Arak, that there is a “high estimation” that attacks on “uranium enrichment sites are part of the plan.” The IDF declined to answer more specific questions about its target list and if any ground operations to retrieve the nuclear weapons-grade uranium were being considered.

Reuters, quoting regime media outlet Fars, reported that joint U.S.-Israeli strikes on Friday hit the Khondab heavy water research reactor. 

A statement released by the IDF said, “Heavy water is a unique material used to operate nuclear reactors, such as the inactive Arak reactor, which was originally designed to have weapons-grade plutonium production capabilities. These materials can also be used as a neutron source for nuclear weapons.”

The IDF statement added that “The plant was a significant economic asset for the terror regime and served as a source of income for the Iranian Atomic Energy Organization, generating tens of millions of dollars for the regime each year.”

The regime’s foreign minister posted a condemnation of Israel and warned the Jewish state, “Iran will exact HEAVY price for Israeli crimes.”

According to an article published by the Washington, D.C.-based Institute for Science and International Security (ISIS), “The IR-40 Arak, aka Khondab, Heavy Water Reactor and Heavy Water Production Plant date to the early 2000s… The reactor core design was ideal for making substantial amounts of weapon-grade plutonium for nuclear weapons.”

STRIKES MAY SET IRAN BACK — BUT LIKELY WON’T END NUCLEAR PROGRAM, UN WATCHDOG CHIEF SAYS

Jason Brodsky, the policy director of United Against Nuclear Iran (UANI), told Fox News Digital, “The one nuclear site which hasn’t been hit to date has been Pickaxe Mountain, so striking that site as part of Operation Epic Fury will be important to further degrade the Iranian nuclear program.”

A White House spokesperson referred Fox News Digital to President Trump’s cabinet meeting comments about Iran’s nuclear weapons program. Trump said on Thursday, “We’re free to roam over their cities and towns and destroy all of their crazy nuclear weapons and missiles and drones that they’re building.”

David Albright, a physicist, founder and president of the Institute for Science and International Security told Fox News Digital that with respect to key nuclear weapons facilities that remain, “The elephants in the tent are Natanz and Isfahan. There was an attack on Natanz that the Iranians revealed, but the Israelis said we are not aware of an attack. So it must have been the U.S.,” he claimed.

He said that Natanz has enriched uranium. “The Iranians were doing recovery operations in the underground fuel enrichment plant there and continuing to build this pickaxe mountain tunnel complex, which could hold enriched uranium. Right next to it is another tunnel complex that was built much earlier, around 2007… And the Iranians sealed it up, fortified it. There is something obviously important there.”

Albright said U.S. and Israeli airstrikes “have not attacked the underground Isfahan site. We know, according to the IAEA [International Atomic Energy Agency], highly enriched uranium is in that site.” He continued that, “There may be an enrichment plant under construction in that underground complex. We would like that site to be attacked.”

Albright warned that the war should not end like the previous U.S.-Israel war with Iran in 2025 with Tehran retaining the “crown jewels” of its atomic weapons program: highly enriched uranium and a number of centrifuges.

He warned, “You don’t want it to come out of this war with the same kind of nuclear weapons capabilities that it had at the end of June war with a higher incentive to build a bomb.” He added, that is why it’s so important “to finish the job,” in Iran. 

U.S. officials and analysts are weighing whether seizing Iran’s main oil export hub could deal a crippling financial blow — but experts warn the high-risk move may not shut off Tehran’s revenue as quickly or completely as expected.

Analysts say U.S. planners face a high-stakes decision: whether seizing Kharg Island would actually disrupt Iran’s oil revenue or leave key export flows intact while exposing American forces to sustained attack. Options under discussion range from interdicting tankers at sea to striking export infrastructure from the air, approaches some argue could pressure Tehran’s finances without putting troops on the ground.

“There’s a big debate going on right now,” R.P. Newman, Marine veteran and counterterrorism analyst, told Fox News Digital. 

Kharg Island handles the vast majority of Iran’s crude oil exports, making it one of the most strategically significant energy nodes in the region and a central pressure point for any effort to economically squeeze Tehran.

“We certainly have the ability, military wise, to take it,” said R.P. Newman, a Marine veteran and counter-terrorism analyst. 

Some analysts argue that taking Kharg could deliver an immediate economic shock, cutting off the regime’s primary source of oil revenue and potentially giving Washington leverage in broader negotiations. 

But such an operation would not be simple.

“It would take thousands to do that,” he said.

U.S. forces already have struck the island hitting more than 90 Iranian military targets, including missile and naval mine facilities, earlier in March while deliberately avoiding oil infrastructure, leaving export operations largely intact.

Retired Adm. Kevin Donegan, former commander of the U.S. Navy’s 5th Fleet, said the same objective could be achieved without putting U.S. forces on the island.

“You could achieve that desired outcome just by constraining the flow that comes out of Kharg after it gets outside the Gulf,” Donegan said.

“You could stop every ship that comes out,” he added.

Robbins said the U.S. could also disable Kharg’s export capability with air power rather than seizing it outright.

An influx of thousands of troops from Marine expeditionary units and the Army’s 82nd airborne division has raised speculation that a ground operation could be on the way. 

But Secretary of State Marco Rubio said Friday U.S. operations could wrap in “weeks, not months” and without ground troops. 

“We are ahead of schedule on most of (the objectives), and we can achieve them without any ground troops, without any,” Rubio told reporters during a trip to Paris for a meeting of G-7 foreign ministers.

Even if U.S. forces were able to seize the island, some analysts warn the economic impact would not be immediate.

“The desired full economic effect of taking Kharg Island is going to be a delayed effect if you don’t also seize underway tankers,” said Gregory Brew, analyst at the Eurasia Group, said. 

Any operation targeting Kharg would strike at one of Iran’s most critical economic assets.

“Sales of petroleum products have generally covered between 30 and 40% of the official state budget,” Brew said. “There’s no question the state budget will take a significant hit.”

But a loss of oil revenue would not necessarily cripple the regime’s core power structure.

“The IRGC has what is in effect a shadow budget,” Brew said. “If anything, its relative position may improve.”

That means that while the government’s official budget would shrink, the Iranian Revolutionary Guard Corps (IRGC) could retain a larger share of the country’s remaining resources through its independent revenue streams.

Even if Kharg were taken offline, Iran would retain other ways to keep exports flowing.

“Iran does have four other export facilities,” Brew said.

Its terminal at Jask, Iran, located outside the Strait of Hormuz, “can handle around one-fifth of the volume of oil that can be exported from Kharg.”

“Stopping completely would require interdicting that traffic as well,” Brew added. 

That means any effort to fully choke off Iran’s oil exports would likely extend beyond Kharg, requiring action against multiple export routes and facilities.

Sustaining the island would prove difficult as well, putting U.S. forces on a sea-locked target within range of Iranian drones, rockets and missiles from the mainland.

“Any deployment to the island will be vulnerable to Iranian counterattack,” Brew said.

“They would be a very small force, very exposed,” said James Robbins, dean of the Institute of World Politics and a former adviser to Defense Secretary Donald Rumsfeld.

Beyond the initial assault, sustaining forces on the island would present additional challenges.

“Once the guys are on the ground, then you have to support them and that would be extremely hard,” Robbins said.

Some analysts also question what a successful seizure would ultimately achieve.

“To what end would be the question,” Robbins said. “I don’t see an endgame to that, to seizing Kharg.”

President Donald Trump has publicly announced a reprieve on strikes on energy infrastructure until April 6, citing “progress” in negotiations with Iran. 

But Iranian officials have accused the president of “psychological warfare” and expressed skepticism. 

Iran already has begun preparing for a potential Kharg invasion, moving additional forces, bolstering air defenses and laying mines and other traps around the island, including along potential landing areas, sources familiar with the intelligence told CNN.

The Pentagon and the Iranian mission to the United Nations could not immediately be reached for comment. 

A Senate hearing got tense and quiet after Illinois father Joe Abraham confronted retiring Sen. Dick Durbin, D-Ill., for not acknowledging his daughter, Katie, who was killed by an illegal immigrant drunk driver.

After Sen. Ted Cruz, R-Texas, expressed his condolences to Abraham, the grieving father thanked him and then proceeded to drill into Durbin.

“I appreciate it. I also appreciate Ranking Member Welch and Mr. Padilla for recognizing that. What I don’t understand is why my senator of Illinois, Mr. Durbin, [I] haven’t heard two words from him toward me,” he said, pointing in Durbin’s direction.

“It’s kind of amazing,” Abraham added.

In the suddenly quiet hearing chamber, Cruz said, “I think it is a fair question to ask.” Abraham answered, “Kind of happy he’s calling it quits.”

After the tense exchange, Abraham again called out Durbin, writing, “You had the chance to show basic humanity, to acknowledge Katie’s life and death, as other senators in your own party did. Instead, silence. Not a call, not a statement, not even basic human acknowledgment.”

Abraham stated that “silence in the face of tragedy isn’t neutrality. It’s indifference.”

“You’re retiring, but for many of us, that comes 30 years too late. And whoever you choose to endorse should be rejected just as quickly, because Illinois cannot afford more of the same,” he added, writing, “Illinois families deserve better than leaders who look away when the consequences don’t fit their narrative.”

He also criticized Durbin for supporting sanctuary policies, saying, “My daughter died in a system shaped by policies you continue to defend.”

“You chose sanctuary policies that give special privileges to those here illegally, while law-abiding Illinois citizens like my family are left unprotected,” wrote Abraham. “That’s not compassion. That’s a failure of leadership.”

COLLEGE STUDENT’S ALLEGED MURDER BY ILLEGAL WENT EXACTLY AS DEMS ‘INTENDED,’ HOUSE SPEAKER SAYS

Abraham’s 20-year-old daughter, Katie Abraham, was killed by an illegal immigrant in a drunk-driving incident while standing at a stoplight in the college town of Urbana, Illinois. The federal government’s immigration crackdown in the Chicago area was launched in Katie’s honor. Dubbed “Operation Midway Blitz,” the effort resulted in more than 4,500 illegal immigrant arrests, according to DHS.

In an interview with Fox News Digital, Abraham, a lifelong Illinois resident, described his family as navigating a “dark wilderness” in the wake of Katie’s death.

“We have been in a dark wilderness, wandering, trying to find our new purpose … without Katie, who we thought would be with us the rest of our lives,” he said.

“She was a beautiful soul,” he added, lamenting, “We thought we’d have our children the rest of our lives.”

Addressing other Illinoisans, Abraham warned, “If anything, God forbid, happens to you, your state under this regime will turn its back on you, 100%.”

“That’s what they’ve done with us and Katie,” he said.
