OPINION — “Nuclear services on each [the Iranian and Israeli] sides have been focused. That’s the place we’re on this conflict, and that’s how far it’s escalated. If a nuclear reactor like [Iran’s] Bushehr [nuclear power plant] have been hit there’s a big threat of a meltdown and leaks of extraordinarily harmful radioactive supplies that might have an effect on all nations within the [Middle East] area, and, in fact hundreds of thousands of individuals together with People and American service members.”
That was Rep. Joaquin Castro (D-Texas) talking final Tuesday at a Home International Affairs Committee assembly on “Securing the Future: Arms Management and Worldwide Safety for the Trendy Age,” the place Thomas G. DiNanno, Underneath Secretary of State for Arms Management and Worldwide Safety was the one witness.
Because the U.S./Israeli air assaults have elevated and Iranian missile and drone strikes continued, Rep. Castro’s concern was echoed by Worldwide Atomic Vitality Company (IAEA) Director Common Rafael Mariano Grossi.
On the listening to, Rep. Castro referred to as consideration to Iran claiming that on March 17, a projectile hit a construction about 1,000 toes from Iran’s Bushehr nuclear energy plant. IAEA’s Grossi referred to as it “the reddest line of nuclear security.”
On March 21, Iran missiles attacked two southern Israeli cities together with Dimona, which is about 8 miles from Israel’s Shimon Peres Negev Nuclear Analysis Heart. This Israeli analysis heart incorporates a secretive nuclear reactor, plutonium reprocessing services, and laboratories — and was the place Israel first developed nuclear weapons within the Sixties.
Throughout final week’s Home committee listening to, Castro and DiNanno tangled over Israel’s nuclear weapons program, however I’ll take care of that under.
Iran’s March 21, ballistic missiles that struck Dimona, injured greater than 20 individuals, however for the primary time penetrated Israeli air defenses close to what’s Israel’s essential nuclear analysis facility. Iran mentioned explicitly it was concentrating on the Negev nuclear analysis heart in retaliation for U.S./Israeli assaults on Iran’s Natanz enrichment facility solely a day earlier.
So ten days in the past, Iran demonstrated its skill to achieve Israel’s most delicate nuclear-related websites, regardless of President Trump and Prime Minister Benjamin Netanyahu claiming earlier that Iran’s missile capabilities had been “destroyed.”
On the night March 24, hours after the above-mentioned Home listening to, Iran claimed a U.S. missile struck the premises of the Bushehr Nuclear Energy Plant, however there was no injury to the nuclear reactor, no accidents to workers, and the plant continued to function usually with radiation ranges secure. That was the second such assault at Bushehr in simply over every week.
A 3rd assault within the neighborhood of Bushehr happened final Friday when Israeli planes struck the Shahid Khondab Heavy Water Advanced in Arak, a key plutonium manufacturing website for attainable use in making nuclear weapons. Israel additionally hit a uranium processing facility within the Iranian metropolis of Yazd, the place they extract uncooked supplies important to the uranium enrichment course of. Once more, the studies have been there have been no radiation leaks.
Al Jazeera reported from Tehran that these current strikes on two main Iranian nuclear-related services might immediate the Iran army to focus on Israeli nuclear websites in Dimona once more, because it did on March 21. On the similar time, IAEA Director Common Grossi reiterated his name for “army restraint to keep away from any threat of a nuclear accident.”
On the March 24, Home listening to, Rep. Castro requested Underneath Secretary of State for Arms Management DiNanno, “What’s the [Trump] administration’s evaluation of the danger of nuclear escalation or radiological catastrophe on this conflict and what steps is the United States taking to forestall it?”
DiNanno initially replied that “operational questions would relaxation with [U.S. Central Command’s Commander] Adm. [Charles] Cooper,” and that “all assets that the [State Department] Nonproliferation Bureau [has] could be made obtainable and can be found ought to they need it.”
DiNanno shortly added, “I’ve had conversations with my colleagues within the Battle Division particularly to this concern and operationally the Battle Division would deal with the kind of issues.”
Requested by Castro if he might share any data he had acquired, DiNanno replied, “Admiral Cooper could be the decision-maker on how that might be, any hypothetical state of affairs could be, addressed.”
Castro then requested a collection of questions on Israel’s nuclear weapons that put DiNanno in a tough state of affairs, however one which has a sophisticated historical past which I’ll clarify under.
Castro mentioned, “I do not imagine that you’ve got adequately addressed the nuclear dangers right here. So, let’s take a step again and set up some fundamental info. The [Trump] administration has mentioned that Iran is, or was, near creating nuclear weapons, however they have not mentioned what Israel’s capability or capabilities are. So, I need to ask you, does Israel have nuclear weapons?”
DiNanno answered, “I am not ready to touch upon that.”
“You’re not ready to touch upon that,” Castro mentioned, after which went on, “It’s a really fundamental query. We’re with an ally, conducting a conflict in opposition to Iran. Everyone knows what American capabilities are; the U.S. Authorities has spoken what Iran’s capabilities are. Are you able to inform us what Israel’s capabilities are? The results, as you understand, are grave. This conflict continues to escalate inform us one thing as Congress, because the oversight physique what’s Israel’s nuclear functionality by way of weapons?
“I can not touch upon that particular query,” DiNanno mentioned, “I would should refer you to the Israelis on that.”
“Does that imply you don’t know?” Castro requested.
DiNanno responded, “I can’t touch upon that sir.”
I’ve to level out that Underneath Secretary DiNanno was following an historic, labeled Govt Department directive which for many years has pressured U.S. officers into what’s been referred to as “implausible deniability,” in relation to the query of Israel’s nuclear weapons arsenal.
Books have been written about how Israel secretly started a nuclear weapons growth program within the late Fifties and with the assistance of some French and American producers by 1967 had constructed a couple of nuclear bombs with radioactive materials from a nuclear reactor close to Dimona.
Conscious of the Israeli exercise, U.S. Presidents John Kennedy and Lyndon Johnson tried to halt this system however, in response to Israeli-American historian Avner Cohen, in 1969 an unwritten settlement was apparently reached between President Richard Nixon and Israeli Prime Minister Golda Meir.
The settlement was that Israel wouldn’t verify it had nuclear weapons nor check any; the U.S. wouldn’t push Israel to provide them up nor be part of the Non-Proliferation Treaty. As well as, the U.S. Authorities adopted as coverage that Israel’s possession of nuclear weapons stay a labeled secret.
That official U.S. Authorities coverage has continued since 1969, and consequently there’s restricted public dialogue and press protection of Israel’s nuclear weapons. The Stockholm Worldwide Peace Analysis Institute in 2025 estimated Israel possesses roughly 90 nuclear warheads, however others recommend numbers as excessive as 200 with nuclear warheads on ballistic and cruise missiles and nicely as nuclear bombs.
Nonetheless, there’s protection not simply within the American press, but additionally within the Israeli press.
For instance, again in June 2002, I wrote in The Washington Publish a narrative that started, “Israel has acquired three diesel submarines that it’s arming with newly designed cruise missiles able to carrying nuclear warheads, in response to former Pentagon and State Division officers, probably giving Israel a triad of land-, sea- and air-based nuclear weapons for the primary time.”
In 2016, the Instances of Israel, utilizing an ordinary attribution “in response to international studies” as a method of not violating their nation’s secrecy, described those self same Israeli submarines as “able to delivering a nuclear payload.”
One purpose Iran’s hardliners desire a nuclear weapon is as a result of Israel, their close by neighbor, has had them for many years.
