The Samson Option is Israel’s deterrence strategy of massive nuclear retaliation as a "last resort" if the state faces existential destruction.
Named after the biblical figure Samson, who collapsed a Philistine temple, killing himself and his enemies, it implies Israel would unleash its nuclear arsenal to devastate adversaries—and potentially the world—rather than face annihilation alone.
This doctrine was coined in the 1960s by Israeli leaders, including David Ben Gurion and Moshe Dayan. Its purpose is not victory, but to ensure enemies face catastrophic consequences if Israel falls. It contrasts with Mutually Assured Destruction (MAD) because it threatens non-nuclear adversaries with nuclear retaliation, not just nuclear powers.
For example, during the 1973 Yom Kippur War, Israel reportedly readied 13 nuclear bombs when Arab forces initially overwhelmed its defences, signalling its readiness to use them.
Israel’s Nuclear Capability and Genesis
Israel has never officially confirmed its nuclear arsenal, a policy known as _amimut_, or deliberate ambiguity. However, it is estimated to possess 90–400 nuclear warheads, deliverable by F-15/F-16 fighters, Dolphin-class submarines, and Jericho ballistic missiles. The CIA estimated 10–20 weapons by 1976, with numbers growing to 75–200 thermonuclear warheads by 2002.
The decision to build the bomb is generally believed to have been made around 1955. Israel embarked on its nuclear armament path, aided by the United States.
A crucial step involved securing a plutonium reactor. In late 1957, Isreal found a willing partner in France, forging ties after the Suez Crisis. France provided Israel with a plutonium reactor and a reprocessing plant at the Demona nuclear facility. Over 2,500 French workers were involved in its construction, operating under strict secrecy, with communications routed through fake post office boxes in Latin America.
The Demona facility was shrouded in secrecy from its inception.
In September 1960, a US ambassador unknowingly overflew the site and was told by an Israeli official, Addy Cohen, that it was a textile factory.
This cover story was subsequently adopted by many Israeli officials. Despite efforts to conceal the programme, the Americans obtained photographic evidence of a reactor being built in the Negev desert in 1960.
US Presidents Eisenhower and JFK sought answers. Ben-Gurion publicly stated in the Knesset that Demona was for peaceful purposes, specifically electricity production. Kennedy pressed for regular inspections by US teams, which visited Demona in 1961, 1962, and 1964.
During these inspections, Israel employed elaborate deception, including building false walls in front of lifts leading to the underground reprocessing plant, thereby hiding it from American teams and even spy planes.
Key components were sourced covertly. The Lam (science laser Bureau) agency played a significant role. In 1965, Shimon Peres recruited Arnold Milchin, a Hollywood producer, as a spy. Milchin photographed blueprints and even enlisted a US nuclear scientist to join his company board. Israel also acquired heavy water, a vital component, from Norway.
By the late 1960s, the bomb was ready. Although a planned nuclear test in the Sinai desert was aborted after Israel’s victory in the 1967 Six-Day War, the Americans gained the full picture of Israel's nuclear capability
by 1968. The US kept this information secret to avoid jeopardising the Nuclear Non-Proliferation Treaty (NPT), which Arab nations subsequently signed, while Israel did not.
An alleged nuclear test occurred in 1979 near South Africa, detected as a "double flash" by a US satellite. Israeli sources later confirmed this was their nuclear test, with the apartheid South African regime allegedly assisting in exchange for nuclear know-how.
Exposure of the Programme
The existence and scale of Israel’s nuclear weapons programme were revealed to the world by Mordecai Vanunu. In the Negev desert, at the Demona nuclear installation, Israel had secretly built a plutonium reprocessing plant, effectively a nuclear bomb factory, located six levels below ground. Israel continues to refuse to acknowledge its existence.
Vanunu, who had worked as a technician at the Demona facility for nine years, was privy to the country’s best-kept secret. In 1986, he duped Israel’s security apparatus by smuggling a camera into the secret plant. His photographs exposed Israel’s nuclear arms programme as far bigger and much more powerful than previously imagined, revealing that enough material was produced annually for 10 bombs. Vanunu fled Israel and travelled through Europe and Asia before reaching Australia. He then took his photographs and story to the _Sunday Times_ newspaper in Britain.
In response, Israeli agents set a trap using an alluring female spy named Cindy, a "honey trap," to ensnare Vanunu in London. He was lured to Rome, where he was kidnapped, injected, and secretly shipped to Israel. He was subsequently convicted of espionage and treason and sentenced to 18 years in jail, of which eleven and a half years were spent in solitary confinement.
Following his release, Vanunu remained effectively a prisoner of the state, forbidden to leave Israel or communicate with foreigners.
