Mossad (Institute for Intelligence and Special Operations, Israel)

Origins

The Mossad’s official website presents Prime Minister David Ben-Gurion’s directive establishing the Institute and a list of its heads, beginning with Reuven Shiloah (1949–1952). The website does not give a date of establishment.¹

According to the Israel Security Agency, on 30 June 1948, a month after the Israel Defense Forces were founded, the Haganah’s intelligence service was dissolved. The new intelligence community had three branches: the Intelligence Service (later Aman), the Political Department (later the Mossad, responsible for operations abroad) and the Internal Intelligence Service (later the ISA).³

In 1952 Ben-Gurion, then Prime Minister and Minister of Defence, appointed Isser Harel, until then head of the internal security service, as head of the Mossad; Harel also chaired the committee of service chiefs.²

Heads

The list on the Mossad website names, in order: Reuven Shiloah, Isser Harel, Meir Amit, Zvi Zamir, Yitzhak Hofi, Nahum Admoni, Shabtai Shavit, Danny Yatom, Efraim Halevy, Meir Dagan, Tamir Pardo and Yossi Cohen (2016–2021).¹

Legal basis

According to media and secondary accounts · not confirmed by official sourcesAccording to the Militarnyi news site, citing i24NEWS (12 May 2026), Mossad director David Barnea stated in a letter to Israel’s Supreme Court that no dedicated statute governs the Mossad’s activities and that the service has no formal external oversight mechanisms.⁴

By comparison, Israel’s internal security service has been governed since 2002 by the General Security Service Law (see Shin Bet).⁵

The capture of Eichmann (1960)

According to the Israel State Archives, in May 1960 Mossad agents led by Isser Harel abducted Adolf Eichmann from Argentina and handed him over to the Israeli police. On 23 May 1960 Ben-Gurion announced in the Knesset that Israel’s security services had captured Eichmann, without naming the country.⁶

The trial before a special bench of the Jerusalem District Court opened on 11 April 1961; on 15 December 1961 Eichmann was sentenced to death and, after the Supreme Court dismissed his appeal (29 May 1962), he was executed on the night of 31 May to 1 June 1962.⁶

Argentina recalled its ambassador and turned to the UN Security Council. In Resolution 138 of 23 June 1960 the Council declared that such violations of sovereignty could, if repeated, endanger peace, and requested Israel to make appropriate reparation, while noting that this in no way condoned the crimes of which Eichmann was accused. On 3 August 1960 the two countries announced that the dispute was closed.^6,7

According to T. P. Kozłowski (2024), in May 1990, during the transit of Soviet Jews through Poland, a Mossad delegation visited the country (see Operation Bridge).⁸
