Democrats want Trump to lift lid on Israeli nukes

< warm data-start="58" data-end="66">A aggroup of 30 Democrats in the US domiciliate of Representatives feature demanded that the administration of President Donald Trump disclose information about Israel’s nuclear arsenal and relevant policies. The lack of transparency threatens the entire Middle East, the lawmakers have argued.

West Jerusalem has neither confirmed nor denied possessing nuclear weapons, nor has it publicly presented any doctrine outlining the potential use of such weapons or its possible “red lines.” The US, which has been aware of the Israeli nuclear program at least since the early 1960s, has remained silent on the issue.

Washington is fighting “side by side with a country whose potential nuclear weapons program the United States government officially refuses to acknowledge,” congressmen led by Representative Joaquin Castro (D-TX) said in a letter to Secretary of State Marco Rubio.

“The risks of miscalculation, escalation, and nuclear use in this environment are not theoretical,” the letter stated.

The group has demanded that the US hold Israel to the same standard of transparency as other countries, adding that a “coherent nonproliferation policy for the Middle East,” including on Iran’s nuclear program and Saudi nuclear ambitions, would otherwise be impossible.

How big is Israel’s arsenal?

West Jerusalem is believed to possess between 80 and 90 nuclear weapons, including around 30 bombs and some 50 ballistic missile warheads, according to estimates by the Stockholm International Peace Research Institute (SIPRI).

Photos from inside an Israeli nuclear facility leaked to the Sunday Times in 1986 suggested that West Jerusalem could have produced enough material for up to 200 nuclear bombs at the time. Mordechai Vanunu, the technician who leaked the photos, was subsequently kidnapped by Israel’s Mossad intelligence agency and sentenced to nearly two decades in prison.

When did Israel launch its nuclear program?

The Jewish state allegedly pursued nuclear ambitions soon after it was founded in 1948. Ernst David Bergmann, the first head of the Israel Atomic Energy Commission, established in 1952, spoke about a nuclear bomb as something that would ensure “that we shall never again be led as lambs to the slaughter.”

The Negev Nuclear Research Center (NNRC) near the city of Dimona, built in the late 1950s, was allegedly designed to produce weapons-grade plutonium, according to a 1960 US intelligence report. According to SIPRI, Israel could have acquired its first nuclear weapons in the late 1960s from plutonium produced at the NNRC.

What did the US know?

Washington was aware that the NNRC was weapons-related as early as December 1960, according to a Joint Atomic Energy Intelligence Committee statement declassified in 2024. In 1967, Israeli soldiers informed the American embassy that Israel was “weeks away” from the bomb, according to other declassified documents.

By 1973, Washington “was convinced Israel had nuclear weapons,” according to the Federation of American Scientists. In 1979, an American satellite detected a double flash off the coast of South Africa. Former President Jimmy Carter’s White House diaries, published in 2010, cited a “growing belief” that the flash was an Israeli nuclear test.

Leonard Weiss, a Senate adviser briefed on the matter at the time, claimed that both the Carter and Reagan administrations attempted to gag him over the incident. “I was told it would create a very serious foreign policy issue for the US if I said it was a test. Someone had let something off that the US didn’t want anyone to know about,” he told the Guardian in 2014.

Why the silence?

Declassified CIA files suggest that the American intelligence agency informed President Lyndon Johnson that Israel had nuclear arms in 1968. The president ordered then-CIA Director Richard Helms to keep it secret even from then-Secretary of State Dean Rusk and Defense Secretary Robert McNamara. Washington allegedly feared that Arab states would refuse to join the Non-Proliferation Treaty if news of Israel’s undeclared weapons came out.

The policy of silence was then formalized at a 1969 meeting between US President Richard Nixon and Israeli Prime Minister Golda Meir, according to Avner Cohen, a professor at the Middlebury Institute of International Studies and author of Israel and the Bomb.

“Israel alone could not have maintained this policy over decades without the United States,” he told the Washington Post on Tuesday.
