Samson Option

Israel has maintained a policy of nuclear ambiguity since 1969, neither confirming nor denying possession of nuclear weapons.[1] Israel is not a signatory to the Nuclear Non-Proliferation Treaty and has never carried out a confirmed nuclear test.[2] Estimates of the arsenal's size are uncertain and conflicting, ranging from approximately 75–130 weapons in some U.S. intelligence assessments to substantially higher figures in published analyses.[2]

Israel's nuclear option was linked to its conventional security strategy at an early stage in the 1950s. An INSS study describes it as an "ultimate insurance policy" if that strategy failed to avert an existential threat; planning for the Dimona nuclear research center began in the mid-1950s, with construction starting in 1959.[1]

Shimon Peres articulated the logic of strategic ambiguity concisely: "The fact that some fear that we have the nuclear option is enough dissuasion," while simultaneously maintaining that Israel would not be the first country to introduce nuclear weapons into the region.[3] When Prime Minister Ehud Olmert appeared in 2006 to allude to nuclear capabilities during a German television interview, his spokeswoman promptly denied that he had admitted possession, reiterating the standard formula.[3] The Jerusalem Center for Security and Foreign Affairs argues that Israel's ambiguous deterrent developed as a "balance of fear" — a means of making any attempt to destroy Israel threaten the attacker's own survival — compensating for Israel's lack of strategic depth, small territory, and limited population.[4]

The name draws directly from Judges 16:30, in which Samson embraces the two central pillars of the Philistine temple and cries, "Let me die with the Philistines!" The verse records that those killed at his death outnumbered those he had killed during his life.[5] The image of a figure who destroys both enemies and self in a final act of desperation gave the concept its essential character: a last resort that inflicts devastating consequences on an adversary even as the actor faces annihilation.

In Hersh's account, secret conferences in late 1964 and early 1965 considered when, rather than whether, to begin mass production of a nuclear arsenal. Hersh says Dimona's supporters argued that only nuclear weapons could provide an "absolute and final deterrent" and presented the Samson Option as a replacement for the historical Masada model.[6] In a footnote, Hersh quotes Norman Podhoretz's later formulation that Israel would fight conventionally for as long as possible and, if facing decisive defeat without outside resupply, ultimately use nuclear weapons.[6] For the advocates in Hersh's narrative, the concept became another way of saying "Never again."[6]

Security analysts distinguish the Samson Option from Israel's broader nuclear posture, treating it as a specific last-resort subset rather than a core national nuclear strategy. An Institute for National Security Studies (INSS) analysis describes it as applicable only at the highest end of realistic war scenarios and dependent on a threatened attack against Israel's existence — likely involving higher-yield weapons than those normally considered usable, and contemplated only in last-resort or near-last-resort circumstances.[7]

The INSS characterizes the option's essential message as: "We (Israel) may have to ‘die,’ but (this time) we won't die alone." Its primary function would not be to communicate a graduated nuclear deterrent, but to signal an implicit promise of counter-city retaliation — a capability likely to deter only high-end nuclear or biological first strikes.[7] The same analysis treats the option as an adjunct to deterrence and certain preemption options, not as Israel's core strategy, and argues that its credibility would depend on selective nuclear disclosure rather than continued total ambiguity: keeping the bomb entirely "in the basement" would prevent Israel from using the residual Samson option at all.[7]

A JNS analysis similarly presents the Samson Option as a high-end deterrent whose value would lie in escalation dominance — signaling that Israel's nuclear-force capabilities would remain functional "at the eleventh hour" — rather than in threatening indiscriminate revenge.[8] Both analyses treat the option as hypothetical, and Israel has never officially acknowledged it as doctrine.[8][9]

The INSS also cautions that ending nuclear ambiguity carries destabilizing risks. The consequences would depend on the types of weapons disclosed, enemy calculations, and command-and-control arrangements; launch-on-warning procedures or delegated launch authority could increase the likelihood of unauthorized or accidental nuclear war.[7]

The most specific historical episode associated with the Samson concept concerns a reported Israeli plan — code-named "Shimshon" (the Hebrew form of Samson) — developed before the Six-Day War of June 1967. The account derives primarily from a 1999 interview conducted by nuclear scholar Avner Cohen with retired Israeli Brigadier General Yitzhak Ya'akov, who had been involved in nuclear-related planning.[10]

According to Ya'akov's account, the plan involved helicopters and commandos transporting an improvised atomic device to a mountaintop approximately 12 miles from the Egyptian military complex at Abu Ageila in the Sinai.[11] A small Sayeret Matkal force was to provide diversion while a team prepared the device. If detonated, the flash and mushroom cloud would reportedly have been visible across the Sinai and Negev, and possibly from Cairo.[10][11] Ya'akov described the underlying logic plainly: "You've got an enemy, and he says he's going to throw you to the sea. You believe him. He says he's going to throw chemical weapons on you…. What are you looking for? Anything you can do to stop him. How can you stop him? You scare him. If you've got something you can scare him with, you scare him."[10]

The operation's stated objective was to halt an Egyptian advance or the use of missiles — not to kill as many Egyptians as possible, but to create a new situation that would force the great powers to intervene or compel Egypt to stop.[10] Ya'akov said the command-and-control concept required authority from both the prime minister and the chief of staff, and he recalled that an order had been drafted and signed by Yitzhak Rabin, though he expressed uncertainty about the precise chain of command and acknowledged that the preparations were improvised.[10]

A reconnaissance flight toward Abu Ageila was attempted but aborted after the crew received a warning that enemy aircraft were taking off; the team identified a mountain and a possible canyon near the Egyptian military concentration but did not complete the flight or conduct rehearsals.[10] Israel's rapid and decisive victory in the Six-Day War rendered the operation unnecessary, and it was dissolved.[10] Ya'akov nevertheless told Cohen that he believed Israel should have proceeded and openly declared its nuclear capability.[11]

A separate and heavily debated episode involves the October 1973 Yom Kippur War. An INSS study reports that on October 7, 1973, Defense Minister Moshe Dayan proposed preparing "a demonstration of the nuclear option" because Israel would have little time and few options.[12] Ministers Yisrael Galili and Yigal Allon opposed the proposal, reportedly calling it "madness"; Prime Minister Golda Meir accepted their position, and no nuclear test or demonstration was carried out.[12] The INSS study concludes that Israel did not conduct nuclear signaling during the first days of the war, and that there is no reliable evidence that Israel armed Jericho missiles with nuclear warheads or used nuclear preparations to pressure Washington.[12]

Seymour Hersh's book offers a starkly different account, reporting that Meir's cabinet authorized the arming and targeting of Israel's nuclear arsenal in the event of total military collapse, with initial target planning including Egyptian and Syrian military headquarters near Cairo and Damascus, and that the weapons were removed from forward positions only after Israel's conventional military situation improved.[6] However, Hersh's account of this episode is disputed: the INSS study identifies conflicting dates in various accounts — October 7 in later testimony, October 9 in an account associated with Avner Cohen, October 8 in Hersh's book, and the night of October 8–9 in an earlier account — and contrasts Hersh's version with the accepted account in which Dayan's suggestion was rejected.[12]

Seymour M. Hersh's book The Samson Option: Israel's Nuclear Arsenal and American Foreign Policy was published by Random House in 1991 and is catalogued by the National Library of Israel as a 354-page work with bibliographical references and an index.[13] The book presents a detailed narrative of Israel's nuclear development, the origins of the Samson concept, and several specific nuclear episodes.[6]

Hersh's treatment has attracted substantial criticism. The Foundation for Defense of Democracies describes the book as containing numerous "stupendous" and sometimes contradictory allegations, including the claim that Israel threatened to use its nuclear arsenal during the 1973 Yom Kippur War to pressure the United States into an arms airlift — a claim Richard Nixon later said had "no foundation whatsoever."[14] The FDD article further states that Hersh's account relied substantially on Ari Ben-Menashe, whom it characterizes as an Israeli con man, noting that Hersh himself later acknowledged that Ben-Menashe "lies like people breathe."[14]

Hersh's book also describes the Samson Option as distinct from, but connected to, Israel's broader policy of nuclear ambiguity. In his account, Israel's public posture maintained uncertainty about nuclear possession, while the Samson concept referred specifically to the extreme contingency in which weapons might be used when survival was judged to be at stake. He concludes that the Samson Option was no longer Israel's only nuclear option by the time he wrote, describing what he characterizes as a later arsenal including battlefield and other nuclear capabilities.[6]

Several aspects of the Samson Option rest on contested or unverified accounts rather than officially confirmed doctrine. Most fundamentally, Israel has never publicly acknowledged a policy or doctrine by this name; published analyses describe it as widely assumed or hypothetical.[9][8]

The reported Operation Shimshon of 1967 rests substantially on the testimony of a single former officer. Israeli historian and government deputy minister Michael Oren publicly rejected the claim, arguing that it relied on one source and that tens or hundreds of thousands of declassified documents from the war contained no supporting evidence; Oren said he had also interviewed Ya'akov and was not convinced by the account.[15] Ya'akov himself was arrested in 2001 on charges related to passing secret information, was acquitted of the main charge, but received a two-year suspended sentence after being convicted of unauthorized disclosure of secret information.[11]

Claims about the scale and composition of Israel's nuclear arsenal remain unconfirmed and vary substantially among estimates.[2] The phrase "Samson Option" is also applied inconsistently across sources — used in some contexts for a specific last-resort retaliation concept and in others more broadly for Israel's high-end nuclear deterrent posture.[9][8] A 2003 Knesset Foreign Affairs and Defense Committee investigation used the phrase "Samson-like step" in reference to a feared potential response by Saddam Hussein if his regime faced destruction — not as a designation of an Israeli nuclear policy.[16]
