The Declassified History of Israel's Nuclear Program

[NuclearID]

The true story is both ironic and historically murky. Here’s a fact checked breakdown with key points on how Israel obtained nuclear weapons.

The U.S. did not want Israel to go nuclear:

• The sitting president at the time, John F. Kennedy, was firmly opposed to Israel developing nuclear weapons. He pressured Israeli leadership repeatedly, demanding inspections of the Dimona nuclear facility and guarantees that it was for peaceful purposes only.

Israel lied and stalled:

• Israel played a game of deception, famously using the term “textile plant” as a cover for Dimona. They allowed only superficial inspections and deliberately hid key parts of their program from American inspectors.

The theft of uranium (NUMEC incident):

• In the 1960s, hundreds of pounds of enriched uranium went missing from the NUMEC facility in Pennsylvania. Later investigations strongly suggested that it was diverted to Israel with the help of Zalman Shapiro, the plant’s founder, who had ties to Israeli intelligence. Declassified documents now heavily support that this was part of a covert Israeli operation to secure fissile material.

U.S. leadership looked the other way:

• After Kennedy’s assassination, Lyndon B. Johnson took a less confrontational stance. There’s strong evidence the U.S. intelligence community knew what was happening, but political leadership made the decision to avoid a direct confrontation. By the time Richard Nixon came in, there was an unofficial understanding: Israel would maintain “nuclear ambiguity” don’t test, don’t talk, and the U.S. won’t push.

It was indeed covered up for decades:

• The whole affair both the uranium theft and the Dimona deception was buried to avoid political fallout and to preserve the U.S.-Israel alliance. Only recently have heavily redacted and declassified documents started confirming what many analysts long suspected: Israel committed state-level nuclear espionage against the U.S. and got away with it.

The U.S. didn’t want Israel to go nuclear, but through a mix of espionage, deception, and realpolitik, Israel did it anyway using stolen U.S. material and Washington chose to look the other way. That’s the quiet irony.

This is how Israel got the start of its nuclear program. It’s not speculation or theory, it happened! They built the foundation of their arsenal using stolen U.S. material.

Today, it’s not believed that Israel’s current nukes rely on U.S. uranium. Most evidence points to later supplies coming from France or South Africa, particularly during the height of their cooperation in the 1970s and 1980s.

And if you think this is just fringe speculation don’t. There are hundreds of sources, many from declassified U.S. government archives, publicly available. What I linked earlier was just a handful pulled from a sea of evidence confirming this entire timeline.

The theft of uranium (NUMEC incident):

• In the 1960s, hundreds of pounds of enriched uranium went missing from the NUMEC facility in Pennsylvania. Later investigations strongly suggested that it was diverted to Israel with the help of Zalman Shapiro, the plant’s founder, who had ties to Israeli intelligence. Declassified documents now heavily support that this was part of a covert Israeli operation to secure fissile material.

The NUMEC Uranium Diversion

• The NUMEC incident—involving the disappearance of over 200 pounds of highly enriched uranium from the Nuclear Materials and Equipment Corporation (NUMEC) in Pennsylvania—was investigated by multiple U.S. agencies. In 1976, the CIA briefed senior staff at the Nuclear Regulatory Commission, stating that the agency believed the missing uranium went to Israel.

Apollo affair - Wikipedia

• A 2010 General Accounting Office (GAO) report, declassified in May of that year, concluded: "We believe a timely, concerted effort on the part of these three agencies [DOE, FBI, CIA] would have greatly aided and possibly solved the NUMEC diversion questions, if they desired to do so."

Kennedy-Ben-Gurion Correspondence

• In 2019, the National Security Archive published a collection of documents, including letters between President John F. Kennedy and Israeli Prime Ministers David Ben-Gurion and Levi Eshkol. These documents revealed Kennedy's insistence on U.S. inspections of the Dimona nuclear facility and his warnings that U.S. support could be jeopardized absent such inspections.

Nixon-Meir Understanding

• Declassified documents from the Nixon administration, released in the early 2000s, shed light on the "nuclear ambiguity" policy agreed upon by President Richard Nixon and Israeli Prime Minister Golda Meir. This understanding allowed Israel to maintain its nuclear arsenal without declaring it, and the U.S. agreed not to press Israel to sign the Nuclear Non-Proliferation Treaty (NPT).

OH! What a bomb this story is!

Most of the puzzle pieces have been declassified between 2000 and 2020, but no one put them all together for mainstream consumption. Probably because it’s politically radioactive, even today.

Given that France’s Dessault sold Israel several IRBM missiles during this period. Which is what Israel built their Jericho Missile off around. A French company worked with Israel at the Dimona plant.

Seems the arming of Israel was a multi-national effort possible

Later on. But not at the start. Initially Israel's program was built on stolen U.S. material. That was the foundation. Only after establishing the basics did they turn to external partners like France or South Africa for further uranium, development, and support.

The building of the dimona plant began around 62-63. France had several hundred workers in Israel working at the plant. Ironically why? The US refused aiding in France’s nuclear program. Consultations to begin the France/Israel nuclear collaboration began in late fifties

Israel and Dessault began working on the Jericho missile program as early as 63.

And let’s not forget the nuances of Israel/US/Soviet alliances. It was not clear in the fifties and sixties if Israel was going to comedown in the Soviet or American power sphere.

So France and Israel where already working with each other on uranium refinement and ballistic missiles before the HEU went missing from NUMEC.


Was there missing HEU from NUMEC?
Yes never said there wasn’t. Did it end up with Israel? Almost certainly.
Was it theft or segments within the US gov deciding to aid Israel. President Johnson was relatively ambivalent about Israel developing nukes unlike Kennedy and others. Johnson was president when HEU went missing.

The man who asserted he saw armed strangers on the dock loading kegs of HEU at night on trucks. With shipping manifest showing they were “bound for Israel”. Not much of a theft if the canisters aren’t disguised in some manner AND there are shipping manifest showing who’s receiving the “stolen” property. And being armed is less an indicator of theft as it is more likely an indicator of guarding a shipment of HEU being transported.

He also didn’t come forward till 79 or 80. After he was fired from by the subsequent owner of NUMEC for job abandonment.

So yeah the HEU absolutely did go to Israel, never doubted it. Never even bothered to question it.
They likely didn’t steal it out from under the eyes of the entire US gov in some form of backstabbing espionage.
They likely had facilitators in the US gov who helped them. You know don’t ask don’t tell.

I’m only delineating this difference or nuance to point out they were not necessarily back stabbing who at the time was a Lukewarm ally (the US).

US relations with Israel in the 50’s and 60’s was hit and miss. There have always been segments of US gov and society who opposed any support of Israel (kinda like today).

What is likely more honest in truth is several hundred lbs of HEU went to Israel.
Facilitated by segments in US gov and industry. France already had a working cooperation in Israel on enrichment and missile technology. All before the HEU went to Israel.

So call it theft or call it a deceptive effort by Israel and segments of the US gov or DOD working to aid Israel in obtaining HEU.
Because France already was and no one wanted the Soviets from capitalizing it.

While the US government, et al, was playing Chess with the Soviets during the Cold War, its citizenry was , and is, wildly supportive of Israel.

It not differ than the Iran Contra affair. Even though Congress outright outlawed aid to the Contra’s it continued. Do you know where to pick up a few hundred TOW missiles? How about several dozen fully armed helicopters, all types? No? Well Lt Col Oliver North did. And he arranged for the Air Force to fly Army weapons and equipment all over the world (And he made a profit).

Now I don’t know what military you served in but in the US a Marine Officer won’t get a case of toilet paper from the US Army without half a dozen sign offs including Generals.

Just like Israel and Nuclear Weapons, the serving quorum of officers and most politicians saw the upside of a fully armed Israel. I would have happily helped out in either endeavor, without orders and totally ignoring whatever claptrap was bleeding out of the Congress in Washington DC.

Charlie Wilson was a hero for funneling arms to the Mujahideen. While Ollie North was a pariah for doing the same thing to rebels in Central America.
Perfectly acceptable, even admirable, to fight communism on the other side of the world. But verboten in our own hemisphere.
What’s that tell you.

Well, it happened in a time when funding rebels wasn't all that trendy in public opinion. Moreso that it was connected to Iran than anything else, probably.

They both occurred basically at same period.
Charlie Wilson and a few deep pockets decided Russia needed resisted and that was ok.
But there always seemed to be some moral aversion of using US covert or subversive tactics to counter Soviet influence efforts in the western hemisphere.
We always knew that the Soviets were supporting political and subversive activities in Latin america. Yet anytime it came to light that the US was countering these Soviet activities. There always seemed to be, what to me is a misplaced outrage, against US counter espionage operations in Latin america.
It’s like there is some assumed predisposition towards socialism or communism implied in the Latin america culture.
It all goes back to the worn out colonizer narrative. Everyone ignores the reality that the United States was a colony at one time as well.
And that any counter argument is met with charged of US imperialism.
Never mind that Russia was one of the original colonizer empires.

Of course LtC North also by arming Iran with Tow missiles left far fewer Iraqi Tanks for us to face just a few short years later. Triple win. Old Tows sold and replaced with Tow II’s and then used against Iraq, our enemy just 4-5 years later. Brilliant idea. Ran a profit. No wonder Congress was upset.
