The Secret Handwritten Memos behind Israel鈥檚 Nuclear Project: What Do They Tell Us and How to Study Them

Or Rabinowitz assesses a mysterious trove of handwritten Hebrew-language notes that seemingly contain secret snippets of Israel鈥檚 nuclear history.

The development of and the concurrent evolution of its policy of nuclear ambiguity, which included an Israeli decision not to join the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), have been at the heart of a growing body of literature in recent years. This burgeoning scholarly interest in Israeli nuclear history has been fueled by access to newly available documents and sources. These include non-Israeli sources, mainly from archives in the United States and the United Kingdom, as well as some Israeli sources that are largely unverified. In this post, I will discuss the backstory of a unique and potentially revelatory set of Israeli sources.

Several years ago, a trove of handwritten Hebrew-language notes that seemingly contained heretofore secret snippets of Israel鈥檚 nuclear history surfaced. An undisclosed source gave Israeli historian Adam Raz 鈥搕he author of   in Hebrew about Israel鈥檚 nuclear history 鈥 an envelope full of handwritten notes, letters, and protocols, all related to Israel鈥檚 nuclear program in the 1960s and 1970s. The notes are generally unsigned (leaving the authorship unclear or in doubt) and many are also undated.

Although several of these tantalizing documents were published in the Israeli , the unclear provenance and unusual backstory of the notes makes it nearly impossible for historians to authenticate them. In other words, there is no authoritative way of telling whether the documents are genuine or not. Naturally, these sources should be treated by researchers carefully.  However, the different handwritings in the notes appear to match those of several important Israeli ministers active in the 1960s, lending credibility to their authenticity. I treat them as an important auxiliary source which sheds light into Israel鈥檚 nuclear history, but not as a sole source for conclusive information on Israel鈥檚 nuclear history. Raz has kindly made these documents available to me, and below I discuss four of these notes.

The , presumably from Minister Yigal Allon, most likely circa 1969-1970, demonstrates that Israel adopted the NPT鈥檚 nuclear test criteria for its own purposes, allowing the Israeli leadership to maintain that Israel was not a nuclear state because it had not conducted a nuclear test. The note, which seems to have been written by Allon to Minister Israel Galili at an unspecified date, states the following: 鈥淵israel, I keep using the agreed term with Kissinger, that Israel is not a nuclear state. This definition stems from the agreement against proliferation of nuclear weapons. According to this agreement, a nuclear state is a state which has exploded a bomb or a device.鈥

The adoption of the NPT鈥檚 nuclear test criteria in this note mirrored Israel鈥檚 official language at the time when discussing the issue with US State Department officials.


A , presumably by Minister Yisrael Galili sometime in 1970, discusses the publication of a story on Israel鈥檚 nuclear program in the . According to the note, the story mentions 鈥渢he agreement we have with the President,鈥 alluding to the 1969 Richard Nixon-Golda Meir deal on Israel鈥檚 nuclear status. The note further attempts to analyze which source within the Nixon administration had approached the paper and leaked assessments on Israel鈥檚 nuclear capabilities, underscoring the secrecy and the sensitivity surrounding the 1969 understanding. The note refers to 鈥淎n attempt to reduce the tension that was created by the President and Kissinger鈥檚 statements opposing the Russian involvement and a call to attain a political solution (albeit by coercion) before Israel threw the entire region into an atomic war (namely Rogers and his friends)鈥, referencing the diplomatic crisis which took place at the time between Israel and the United States against the backdrop of Soviet military deployment in Egypt, during the last stage of the Israel-Egyptian War of Attrition.

鈥淭here are a few possibilities:

 1. The same circle that does not know about the agreement we have with the President.

2. The circle which knows and opposes the President鈥檚 position in this matter.

3. An attempt to reduce the tension that was created by the President and Kissinger鈥檚 statements opposing the Russian involvement and a call to attain a political solution (albeit by coercion) before Israel threw the entire region into an atomic war (namely Rogers and his friends).

Two additional documents pertain to the earlier years of the Israeli program.

 was presumably written by Finance Minister Pinchas Sapir. Indeed, according to Sapir鈥檚 daughter, it is his handwriting. In the early 1960s, the Dimona project caused internal political tension and did not enjoy a consensus. In addition, the projected costs of the reactor鈥檚 construction were widely underestimated. In an undated note seemingly written by Finance Minister Pinchas Sapir to Minister Yisrael Galili, Sapir asked: 鈥渉ad we known in advance that it will cost 340 million dollars 鈥 would we have voted for Dimona?鈥. 

The note underscores the tension between those in the Israeli leadership who spearheaded the construction of Dimona, led by Shimon Peres and Moshe Dayan, and those who doubted it and its financial feasibility, like Allon and others.

A , written by unknown author (possibly Yisrael Galili) to unknown recipient, dates from September 1963. It points to the fact that Israel saw itself as complying strictly with the nuclear-related commitments undertaken by David Ben-Gurion in his letters to President John F. Kennedy, referred to in the note as 鈥淏.G letters.鈥 The note consists of a list of short explanatory statements on the nature of these commitments and how Israel interprets them:

  • 鈥淲e did not disclose the object of the factory;鈥
  • 鈥淲e did not commit to inspection;鈥
  • 鈥淲e mentioned and stressed sovereignty in the timing of friendly inspections;鈥
  • 鈥淲e did not break from the content of B.G letters;鈥
  • and 鈥淭he French inspection procedure on the fuel before start-up
