Kennedy’s toughest letter on Dimona left Washington on a Saturday afternoon. By Sunday night the man it was written for had resigned, and the letter sat undelivered at the embassy in Tel Aviv.

One letter, two prime ministers

A demand from one head of government to another, drafted, cabled and then withdrawn because the addressee resigned, is the cleanest test in the record of what the United States asked of Israel over Dimona and what it got.

On 15 June 1963 the State Department cabled a letter from President Kennedy to Prime Minister Ben-Gurion. It asked for American scientists to visit the reactor at Dimona that summer, again in June 1964 and every six months after that, with access to every part of the site. On 16 June Ben-Gurion resigned. The letter was never delivered. Three weeks later the same demand went to his successor, and 45 days after that Israel answered.
